    Public acceptance of radioactive waste management alternatives depends in part on public perception of the associated risks. Three aspects of those perceived risks were explored in this study: (1) synthetic measures of risk perception based on judgments of probability and consequences; (2) acceptability of hypothetical radioactive waste policies, and (3) effects of human values on risk perception. Both the work on synthetic measures of risk perception and on the acceptability of hypothetical policies included investigations of three categories of risk: (1) Short-term public risk (affecting persons living when the wastes are created), (2) Long-term public risk (affecting persons living after the time the wastes were created), and (3) Occupational risk (affecting persons working with the radioactive wastes). The human values work related to public risk perception in general, across categories of persons affected

    1984-01-01

    This dissertation examines the problem of the disposal of high-level nuclear waste in the Pacific region. There is a consensus of scientific opinion that the technical difficulties in waste disposal can be overcome. The most acceptable solution seems to be the multi-barrier approach for deep land-based geologic disposal. A questionnaire survey on the perception of nuclear and other hazards, conducted with student populations in Japan and Australia, and a survey of reporting of nuclear events in Pacific newspapers over the period 1946 to the 1980s, reveal that the image of nuclear weapons dominates public views on the risks associated with waste disposal in Australia, Japan, and the Pacific Islands. The problem of finding a suitable site for a nuclear waste disposal facility is to a large extent political. The capacity of anti-nuclear groups to influence waste disposal policies in Australia, Japan, and the Pacific Islands is examined. Current public attitudes toward nuclear waste disposal will delay the further development of activities connected with the nuclear fuel cycle, but this may change over time if the connection between commercial nuclear power and nuclear weapons can be severed more effectively. The most urgent problem in the region is the waste from the ambitious nuclear power programs of Japan, South Korea, and Taiwan

  4. Radioactive Waste Transport: Managing Risk Perception and Communication

    International Nuclear Information System (INIS)

    Murray, Ch.

    2009-01-01

    The implementation of a national transportation system for spent nuclear fuel and high-level waste that merits public trust and confidence will require the delivery of consistent, accurate and timely transportation messages; stakeholder and public understanding of the need for, and safety of, shipments; and effective two-way communication to address stakeholder concerns in its decision-making processes. Building the trust and consent of stakeholders and the public is complex and challenging. In order to accomplish this goal, it is imperative to understand how and why members of society develop various perceptions of risks and assessments of benefits with regard to the nuclear energy cycle. Understanding the basis and reasons for the public's beliefs concerning the nuclear energy cycle will allow OCRWM to more effectively address concerns regarding the national transportation program. This paper will examine how a person's gender, sources of information, world-view, culture, emotion, cognition, and other factors affect their beliefs and perceptions of risk. It will also explore the reasons why nuclear energy and nuclear waste are viewed with such a distinctly different attitude than other hazardous materials that pose a comparable or greater hazard. Drawing on research from prominent experts in risk perception and communication methods, this study will conduct a unique investigation into the perspectives of a diverse set of key stakeholders and experts involved in the transportation process. This paper will present several hypotheses on why there are unique challenges involved in communicating about transportation of spent nuclear fuel and other nuclear fuel cycle activities, and also present recommendations for remediating such challenges.

    This paper focuses on the risk perception associated to the installation of low and intermediate level radioactive waste (LLRW and ILRW) disposal facilities. The purpose is to give support for the implementation of a repository in Brazil. Public acceptance results from a long term work and trust is vital for the process as it takes long to be conquered but might be shortly lost. Therefore, it is essential to care about the way each step is conducted. The knowledge about the system and the risks, the comprehension about these risks, the commitment with safety, adequate support systems for the project (legislation, involved institutions) and the excellence as a goal to be reached are extremely important parameters. The involvement of all interested parties in the decision-making process is condition for a successful and publicly acceptable implementation of such project. The steps for public acceptance of a repository are summarized as follow: Risk perception: to verify how the local population understand and feel the installation of a repository in the region. Media observatory: to continuously follow the news reaching the region where the repository will be installed, including different media. Local population social/economical/cultural profile identification: to determine the local population social/economical/cultural profile; to conduct a survey to know their expectations, allowing the proposal of compensation and incentives to fully account for their expectations. Finally, the philosophy governing this Project is: on doubt, the public must be heard and only after this public hearing the policies concerning the project shall be formulated. (author)

    Disparate perceptions of risk have emerged as one of the critical issues confronting the future of commercial nuclear power. This paper explores the origins and possible ramifications of the public's perception of risks associated with commercial nuclear power and related high-level nuclear waste disposal programs. This paper summarizes the results of numerous psychometric studies and public opinion polls that analyze the relationship of risk to nuclear power and waste management

  8. Citizen perceptions of risks associated with moving radiological waste

    1996-01-01

    Much has been written about public support or opposition to the siting of hazardous waste facilities and more generally about concern for radioactive contamination. Much less has been written about the perceived risks of citizens' specific concerns about the transportation of radiological waste to temporary or permanent sites. This study reviews the existing literature in the area and presents new data on the subject from an Idaho survey. The new data indicates: (1) age, gender, and knowledge are the key variables predicting opposition to the transportation of such waste, (2) the primary concern among the opposing and unsure public is the planned use of trucks to move the TRU waste, and (3) respondents have high degrees of trust in officials who make decisions based on technical knowledge, are charged with the safety of transporting TRU waste, and who respond to mishaps. These attitudes need to be understood by policy makers and administrators when designing and implementing waste-transportation programs. 19 refs., 4 tabs

    The management of healthcare wastes is receiving greater attention because of the risks to both human health and the environment caused by inadequate waste management practices. In that context, the objective of this study was to analyse the healthcare waste management practices in hospitals of the Algarve region, Portugal, and in particular to assess the risk perceptions of, and actual risk to, healthcare staff. The study included three of the six hospitals in the region, covering 41% of the bed capacity. Data were collected via surveys, interviews, and on-site observations. The results indicate that waste separation is the main deficiency in healthcare waste practice, with correct separation being positively related to the degree of daily contact with the waste. Risk perceptions of healthcare staff show the highest levels for the environment (4.24) and waste workers (4.08), and the lowest for patients (3.29) and visitors (2.80), again being positively associated with the degree of daily contact. Risk perceptions of healthcare staff are related to the difficulties of the correct separation of wastes and the lack of knowledge concerning the importance of that separation. The risk of infection with needlesticks/sharps is higher during patient care than during waste handling, and the frequency of these injuries is related to the daily tasks of each healthcare group (doctors, nurses, and housekeepers). Furthermore, legislative definitions and classifications of healthcare wastes appear to have conditioned the management practices associated with, and the perceptions of risk concerning, healthcare wastes.

    1987-02-01

    A research project looking at the public's attitudes towards the siting of radioactive waste depositories is reported. The risk perception studies seek to compare expert and lay understanding of risk. Adverse public reactions to risk can only be understood if it is known how people relate to risks in their everyday or working lives. Social trends and experiences are important, for example, the adverse public opinion on the siting of nuclear waste facilities. A number of elements have been identified as common to different risk areas such as chemicals, drugs, food or radioactive waste. These are the clashing of values, polarization of beliefs or clashes of interest.

  11. Proposal for a questionnaire to assess risk perception concerning a radioactive waste repository

    One of the key features for public acceptance of nuclear energy is the belief that radioactive waste can be managed safely, in order to protect human beings from its possible harmful effects in present and future generations. In this sense, it is essential to understand how people perceive the risk associated with radioactive waste and which the main factors driving their attitudes toward its disposal are. One of the ways to achieve this understanding is through opinion polls. In this study, a questionnaire focused on the nuclear energy acceptability issue and its association with radioactive waste management was proposed, covering the following aspects: attitudes towards radioactive waste and nuclear power, credibility on institutions and sectors responsible by the nuclear safety, identification of perceived benefits, risk perception of specific technologies and activities, perception of real risk, emotional reaction comprehension and precautionary principle. Results obtained from a pilot questionnaire application are presented and discussed in this paper. (author)

    To study the homogeneity and influences on scientists' perspectives of environmental risks, the authors have examined similarities and differences in risk perceptions, particularly regarding nuclear wastes, and policy preferences among 1011 scientists and engineers. Significant differences (p<0.05) were found in the patterns of beliefs among scientists from different fields of research. In contrast to physicists, chemists, and engineers, life scientists tend to: (a) perceive the greatest risks from nuclear energy and nuclear waste management; (b) perceive higher levels of overall environmental risk; (c) strongly oppose imposing risks on unconsenting individuals; and (d) prefer stronger requirements for environmental management. On some issues related to priorities among public problems and calls for government action, there are significant variations among life scientists or physical scientists. It was also found that-independently of field of research-perceptions of risk and its correlates are significantly associated with the type of institution in which the scientist is employed. Scientists in universities or state and local governments tend to see the risks of nuclear energy and wastes as greater than scientists who work as business consultants, for federal organizations, or for private research laboratories. Significant differences also are found in priority given to environmental risks, the perceived proximity of environmental disaster, willingness to impose risks on an unconsenting population, and the necessity of accepting risks and sacrifices. 33 refs., 3 figs., 9 tabs

  13. Risk perception of various technical options in the field of radioactive waste management

    Cameron, F.X.

    1996-01-01

    The author's group had a wide ranging discussion of risk and, at the very end of the discussion got to the question that was posed to them, which is that of risk perception of various technical options in the field of radioactive waste management. Some of the points that were made in this discussion is a reality that the group, as decision-makers, have to deal with, and it has to be treated as a reality. Secondly, the scientist looks at risk from the classic definition of ''probability times consequences'', but the public only looks at the consequences side of the equation, and too often the probability of something happening is treated as a probability of one that it will actually happen. A third problem that was identified in this area is that often the efforts to make the disposal of waste safer may contribute, in the public mind, to the fact that the risk is even more hazardous. And the last problem is that people do not trust what a decision maker is saying when he talks about the fact that there is little probability of something happening. The group then went on to a discussion of how he should try to treat risk perception. One point that was made is that voluntary acceptance of a risk is important. A second point that was made on how to deal with risk perception problems is that the group could try to put the risk of radioactive waste disposal in the perspective of other risks to society, from the chemical industry for instance. The group also talked about the possibility of putting the benefits in perspective for people. Another point was that the group should have different communications strategies for different audiences. But, the more the public is involved in the decision making process, the more comfortable they are going to be with the risk, and the more consistent the perception of risk may be with the scientific definition thereof. In terms of new technologies, new innovations on the generation and management of waste, although these may actually

    A survey was made to determine the public risk perception of several industrial hazards. A free response approach was used in order for respondents to generate their own alternatives. The general class of hazard investigated here included all hazardous industrial facilities. The free response survey was used to study public perception of: (a) the closeness of the nearest hazardous industrial facility (as estimated by the respondent); (b) the sort of facility it is; (c) the sorts of risk associated with it; and (d) the persons placed at risk by it. Respondents also identified the risks of, and the persons placed at risk by, both a toxic chemical disposal facility and a nuclear waste disposal facility. Results of this study thus can inform us of the unprompted concerns of the public regarding a wide variety of industrial facilities

    1998-01-01

    This article examines how members of the lay public factor risk perceptions, trust and technical information from differing scientific sources into policy judgements about potentially hazardous facilities. Focusing on radwaste storage repositories, we examine how members of the public filter new information about potential hazards through risk perceptions, and adjust their own beliefs about risks in light of that information. Scientists play a large (and increasing) role in public policy debates concerning nuclear waste issues, in which public perceptions of human health and environmental risks often differ substantially from scientific consensus about those risks. Public concerns and uncertainties are compounded when scientists from competing groups (government agencies, scientific institutions, industries, and interest groups) make different claims about the likely health and environmental consequences of different policy options. We show the processes by which the public receive and process scientific information about nuclear waste management risks using data taken from interviews with 1800 randomly selected individuals (1200 in New Mexico, and 600 nationwide). Among the more important findings are: (1) members of the public are able to make quite reasonable estimates about what kinds of positions on the risks of nuclear waste disposal will be taken by scientists from differing organizations (e.g. scientists from environmental groups, government agencies, or the nuclear industry); (2) in assessing the credibility of scientific claims, members of the public place great emphasis on the independence of the scientists from those who fund the research; and (3) prior expectations about the positions (or expected biases) of scientists from different organizations substantially affects the ways in which members of the public weigh (and utilize) information that comes from these scientists

    1994-08-15

    The Department of Energy`s program for disposing of nuclear High-Level Waste (HLW) and transuranic (TRU) waste has been impeded by overwhelming political opposition fueled by public perceptions of actual risk. Analysis of these perceptions shows them to be deeply rooted in images of fear and dread that have been present since the discovery of radioactivity. The development and use of nuclear weapons linked these images to reality and the mishandling of radioactive waste from the nations military weapons facilities has contributed toward creating a state of distrust that cannot be erased quickly or easily. In addition, the analysis indicates that even the highly educated technical community is not well informed on the latest technology involved with nuclear HLW and TRU waste disposal. It is not surprising then, that the general public feels uncomfortable with DOE`s management plans for with nuclear HLW and TRU waste disposal. Postponing the permanent geologic repository and use of Monitored Retrievable Storage (MRS) would provide the time necessary for difficult social and political issues to be resolved. It would also allow time for the public to become better educated if DOE chooses to become proactive.

    Understanding public perceptions of risks is increasingly considered to be important in order to make sound policy decisions. For many years, social scientists have been working to understand why the public is so concerned about nuclear energy and radioactive waste. Indeed, risk perception studies have essentially focused on high-level nuclear waste. As a result, there is now a fair understanding of what determines public support or opposition to high-level nuclear waste storage and disposal facilities. However, to date, little research has been conducted into radioactive waste from mining and milling of uranium ores. In France, such waste have a much debated legal status, which illustrates their ambiguous origin (natural versus artificial) and the manner people can perceive them. Therefore, it seems relevant to explore the individual judgements, attitudes and beliefs towards risk associated with uranium mill tailings. The present study provides a structural model based on both the identification and analysis of implicit dimensions underlying risk perception (psychological, cultural, moral...) applied to the case of french uranium mill tailings. One objective of the research has been to develop an interview grid based on this conceptual model in order to elicit social demand beyond public attitudes. Semi-structured interviews have been conducted on site in french uranium bearing areas. The relationships inferred between identified risk characteristics and contextual risk perceptions suggest that five majors thematics (time, space, nature, ethics and trust) build determinants of the public's perceptions of risk related to waste from mining and milling of uranium ores.

    Public perception and acceptance of nuclear energy is now the most critical question concerning the future of nuclear energy. This is a review of the dynamics of societal risk taking as applied to nuclear power. It is shown that the human intellect is not well equipped for making decisions about risky activities. Risk-benefit relations are discussed. Some of the possible reasons why nuclear power is presently unpopular are described. Responses to a Battelle questionnaire on attitudes toward nuclear waste disposal are discussed

    The disposal of nuclear waste has gained attention of the public for decades. Accordingly, nuclear waste has been a prominent issue in natural, engineer and social science for many years. Although bearing risks for todays and future generations hazardous waste in contrast is much less an issue of public concern. In 2011, we conducted a postal survey among Swiss Germans (N = 3.082) to learn more about, how nuclear waste is perceived against hazardous waste. We created a questionnaire with two versions, nuclear waste and hazardous waste, respectively. Each version included an identical part with well-known explanatory factors for risk perception on each of the waste types separately and additional questions directly comparing the two waste types. Results show that basically both waste types are perceived similarly in terms of risk/benefit, emotion, trust, knowledge and responsibility. However, in the direct comparison of the two waste types a complete different pattern can be observed: Respondents perceive nuclear waste as more long-living, more dangerous, less controllable and it, furthermore, creates more negative emotions. On the other hand, respondents feel more responsible for hazardous waste and indicate to have more knowledge about this waste type. Moreover, nuclear waste is perceived as more carefully managed. We conclude that mechanisms driving risk perception are similar for both waste types but an overarching negative image of nuclear waste prevails. We propose that hazardous waste should be given more attention in the public as well as in science which may have implications on further management strategies of hazardous waste.

    Perception of risks by people depends on many factors, either characterizing the individuals, or specific to the risk sources. The risk concept, which confuses the issue, is precised first. Second, the perception phenomenon is presented as an interactive process involving the individual, the hazard, and the social context. Third, dimensions of perception are listed and used to describe the perception of radiation risks. Finally, the relation between perception and attitude is clarified. (author) 50 refs

    Most members of the public view the risks of nuclear power as uniquely hazardous. A survey in 1993 found that Canadians rank nuclear waste as the eleventh highest risk to their health. The trouble is that the public are not simply misinformed; rather, they view risk as something different from the product of probability of occurrence of an event multiplied by the measure of its harmful consequences. Among the 30 to 40 factors that influence public perception of risk, or acceptance of technology, are some that the scientific and technical community has hitherto failed to heed. Many of these factors can in fact be accommodated in the design, development and public presentation of nuclear projects. Such an accommodation of the public's views would involve dealing with factors like voluntariness, controllability, reversibility, equity and fairness, benefits, and trust in institutions. 9 refs

    Conflicts on technical issues frequently involve disagreements between the public and the technologists. This paper summarizes the major characteristics of three groups of technologists and four groups of the public which lead to many of the disagreements. To advance the mores of making decisions involving complex science or technology, technologists should develop an understanding of what information is needed for decisions, of the need for two-way communication with the public, and to become responsible for the accuracy and honesty of risk communication messages

    1996-11-01

    The first part of this review discusses the importance of risk. If there is any relation between the emotional and rational risk perceptions (for example, it is believed that increased knowledge will decrease emotions), it will be a desirable goal for society, and the nuclear industry in particular, to improve the understanding by the laymen of the rational risks from nuclear energy. This review surveys various paths to a more common comprehension - perhaps a consensus - of the nuclear waste risks. The second part discusses radioactivity as a risk factor and concludes that it has no relation in itself to risk, but must be connected to exposure leading to a dose risk, i.e. a health detriment, which is commonly expressed in terms of cancer induction rate. Dose-effect relations are discussed in light of recent scientific debate. The third part of the report describes a number of hazard indexes for nuclear waste found in the literature and distinguishes between absolute and relative risk scales. The absolute risks as well as the relative risks have changed over time due to changes in radiological and metabolic data and by changes in the mode of calculation. To judge from the literature, the risk discussion is huge, even when it is limited to nuclear waste. It would be very difficult to make a comprehensive review and extract the essentials from that. Therefore, we have chosen to select some publications, out of the over 100, which we summarize rather comprehensively; in some cases we also include our remarks. 110 refs, 22 figs

    The essential characteristics of the issue of radioactive waste management can be conceptualized as complex, with a variety of facets and uncertainty. These characteristics tend to cause people to perceive the issue of radioactive waste management as a 'risk'. This study was initiated in response to a desire to understand the perceptions of risk that the Korean public holds towards radioactive waste and the relevant policies and policy-making processes. The study further attempts to identify the factors influencing risk perceptions and the relationships between risk perception and social acceptance.

    1999-01-01

    This paper describes empirical work on risk perception and some related dimensions, in particular with regard to radiation and nuclear power hazards. Most of the data cited come from a current CEC project in which 5 countries in Western Europe have participated. Models of risk perception are discussed and some generally valid findings concerning risk perception are summarized. Risk is seen to be a primary factor in many policy matters and clearly, to the public, more important than utility considerations. Previously formulated models (the Psychometric Model and Cultural Theory) are found to be deficient and a much more efficient alternative is suggested. It is stressed that risk perception is of interest foremost because it can be of value to decision makers in making difficult policy decisions in matters of risk. Hence, it is important to ask what facets of perceived risk are most strongly related to demand for risk mitigation. It is found that expected severity of consequences of an hazard is the clearly most important dimension. The paper concludes with a brief summary of a case study of Swedish experience with high-level nuclear waste repository siting

  11. Psychological aspects of nuclear waste disposal: Long time perception and the question of discounting of risks

    Subjects of different ages and basic training indicated how they perceived risks related to spent nuclear fuel storage and located at different points of time into the future. The results indicated that minorities in all groups, ranging from about 10 to 40%, did not want to discount risks into the future. Those who discounted exhibited great inter and intra group variability. The physical discounting curves for e.g. both total radiation and for Pu-239 and -240 are within the range of curves generated by the groups for subjective discounting of risk. Politicians and experts were attributed equal shares of responsibility for risks of spent nuclear fuel in the future. About 10% to 40% of the subjects did not wish to discount responsibility. Discounting rates for those discounting varied so that some subjects decreased the level of responsibility to less than half 10 000 years into the future while others attributed this level of responsibility for 100 000 years and more.

    Many factors are involved in the perception of a risk by individuals. Some are individual related (psychology, knowledge, experience), others describe the social environment (culture, ideology), others at end precise the nature of the risk. The word risk has various meanings and is understood differently by the three main categories involved in risk management, that is engineers, administrators and lay public. Several models which describe the perception phenomenon are presented. The dimensions affecting perception are listed. Based on public opinion poll data, a risk taxonomy is proposed, perceived nuclear risks are compared with other risks, and results are given concerning trust in the information diffused and the credibility of those in charge of nuclear activities.

    The perception of risks involves the process of collecting, selecting and interpreting signals about uncertain impacts of events, activities or technologies. In the natural sciences the term risk seems to be clearly defined, it means the probability distribution of adverse effects, but the everyday use of risk has different connotations (Renn, 2008). The two terms, hazards and risks, are often used interchangeably by the public. Knowledge, experience, values, attitudes and feelings all influence the thinking and judgement of people about the seriousness and acceptability of risks. Within the social sciences however the terminology of 'risk perception' has become the conventional standard (Slovic, 1987). The mental models and other psychological mechanisms which people use to judge risks (such as cognitive heuristics and risk images) are internalized through social and cultural learning and constantly moderated (reinforced, modified, amplified or attenuated) by media reports, peer influences and other communication processes (Morgan et al., 2001). Yet, a theory of risk perception that offers an integrative, as well as empirically valid, approach to understanding and explaining risk perception is still missing". To understand the perception of risk is necessary to consider several areas: social, psychological, cultural, and their interactions. Among the various research in an international context on the perception of natural hazards, it seemed promising the approach with the method of semantic differential (Osgood, C.E., Suci, G., & Tannenbaum, P. 1957, The measurement of meaning. Urbana, IL: University of Illinois Press). The test on seismic risk perception has been constructed by the method of the semantic differential. To compare opposite adjectives or terms has been used a Likert's scale to seven point. The test consists of an informative part and six sections respectively dedicated to: hazard; vulnerability (home and workplace); exposed value (with reference to

    The paper does the following: Describes the time trends between 2001 and 2005 in terms of policy intention, perceived risk, trust and attitude Analyzes the relationships between policy attitude - the major dependent variable - and the explanatory variables of perceived risk, trust and attitude. Determines whether policy attitude variation across time, municipalities and genders can be accounted for by variation in perceived risk, trust and attitude. Random samples of 2000 persons living in Oesthammar and Oskarshamn were approached with a mailed questionnaire in 2005 (as was done in 2005). After two reminders, 888 had returned filled out questionnaires, yielding a total response rate of 50 percent, taking into account that some persons had moved without giving a forwarding address to the post office, and that some were unable to answer due to illness or old age. (1). There was a substantially more positive attitude to a local SNF repository in 2005 than in 2001, after an intervening period of phase 2 site investigation. This was true for men and women, both municipalities and with all the response measures analyzed. Men were more positive than women, and had developed more strongly in the positive direction than women had. The attitude in Oskarshamn was somewhat more positive than in Oesthammar. (2). Policy intention was well accounted for by the explanatory variables used here, close to 64 percent of the variance. The most important explanatory variables were epistemic trust, attitude to the repository and social trust, in that order. The differences among these three variables were small with regard to explanatory power. (3) Variation in policy attitude across time, municipalities and gender was reduced in an analysis of covariance with risk, trust and attitude as controlling factors. Hence, these factors explain a large fraction of the variation in policy attitude as observed here. Yet, the time trend was not fully explained and gender variability remained to

    A research project looking at the public's attitudes towards the siting of radioactive waste depositories is reported. The risk perception studies seek to compare expert and lay understanding of risk. Adverse public reactions to risk can only be understood if it is known how people relate to risks in their everyday or working lives. Social trends and experiences are important, for example, the adverse public opinion on the siting of nuclear waste facilities. A number of elements have been identified as common to different risk areas such as chemicals, drugs, food or radioactive waste. These are the clashing of values, polarization of beliefs or clashes of interest. (UK)

    The article on the risks and perceptions of nuclear power was previously published in the Times Higher Education Supplement, May 1987. The public attitude towards risks associated with nuclear power, compared with other risks in everyday life, is examined. Results of psychological studies of the perceived risk of nuclear power are also discussed. The author argues that fear of nuclear catastrophe is not one which can be brushed aside by statistics or punditry. (UK)

    Perceptions of risk from radiation have been studied systematically for about 20 years. This paper summarises the key findings and conclusions from this research with regard to the nature of risk perceptions, the impacts of these perceptions, and the need for communication about radiological hazards. Perhaps the most important generalisation from research in this area is that there is no uniform or consistent perception of radiation risks. Public perception and acceptance is determined by the context in which the radiation is used -and the very different reactions to different uses provide insight into the nature of perception and the determinants of acceptable risk.

  1. Risk perception in planning

    The general public's perception of the risks involved with hazardous industries is increasing, especially in countries that high environmental amenity characteristics. This increased public awareness of risk may be an important factor in the future of countries who produce a large quantity of petroleum and chemical products. However, existing decision-making processes for determining safety controls do not take sufficient account of the community perception of risk. Identification of perceived risk levels could contribute to the determination of safe land-use planning policies and practices. The objective of land-use planning for hazardous industries is to reduce the gap between the calculated or technical assessment of risk and the risk as perceived by the community. This also facilitates a balanced approach in the decision making process between meeting industry requirements and community concerns. The comprehensive analysis presented in this study, based on a questionnaire given to residents in each of the three study areas (Australia, Japan and Korea), focused on identifying and measuring the respondent's understanding of the risk posed by nearby hazardous industrial developments.

    This paper discusses how equity concerns are an important component of the debater on controversial public policy decisions such as those regarding high-level waste disposal. In science policy, concepts of fairness need to be applied to what counts as evidence, as well as to process (means) and outcomes (ends). A science policy decision that involves technologies perceived as risky may have a better chance of enduring over time if all the key parties feel that they have been fairly treated. One task of risk communication is to engage in a dialogue with affected parties and the public about what is fair in terms of process, evidence, and outcomes

    Public perceptions of risk will probably always be unsatisfying to a scientist. Public perceptions are formed by the actions of institutions which have goals other than formation of an informed public opinion, such as the schools, the media, business and the government. In this environment, it seems unrealistic to expect public opinion to reflect scientific realities. The talk will focus on the media as an opinion-former and will discuss several non-nuclear issues as illustrations: plague in New Mexico, Toxic Shock Syndrome, and Injuries as a Public Health Problem. Ultimately however, we are confronted with two wonderfully complex matters: can risk be adequately expressed or measured in universally comprehensible or broadly acceptable terms; and the mysterious movements of the public and collective mind

    One of the key features for public acceptance of nuclear energy is the belief that radioactive waste can be managed safely, in order to protect human beings from its possible harmful effects in present and future generations. In this sense, it is essential to understand how people perceive the risk associated with radioactive waste and which the main factors driving their attitudes toward its disposal are. One of the ways to achieve this understanding is through opinion polls. In this study, a questionnaire focused on the nuclear energy acceptability issue and its association with radioactive waste management was proposed, covering the following aspects: attitudes towards radioactive waste and nuclear power, credibility on institutions and sectors responsible by the nuclear safety, identification of perceived benefits, risk perception of specific technologies and activities, perception of real risk, emotional reaction comprehension and precautionary principle. Results obtained from a pilot questionnaire application are presented and discussed in this paper. (author)

  5. Cultural approach to the perception of risk. Analyzing concern about siting of a high-level nuclear waste facility in Finland

    1996-01-01

    The study of local residents' attitudes toward siting a high-level nuclear waste facility in Finland took place in three municipalities (Eurajoki, Kuhmo and Agnekoski), which are being considered possible host communities for the plant. The survey showed that the NIMBY phenomenon is a common reaction in two of the three municipalities, and in the third a polarization of opinions into two opposing camps is evident. The analysis of the data indicates that the opposition consist of people who have less education, less knowledge about the facility, lower incomes, and a lower occupational status. The social base of the proponents is the opposite. The persons most critical towards the possible siting can be found among women, older people, voters of the Greens, retired persons and farmers. People who welcome nuclear waste in their vicinity can be found among men, the middle-aged, voters of the Conservative Party and business owners. The study of the perception of possible negative impacts (health and safety, environmental, economic and social) showed that residents in Kuhmo and Adnekoski were more concerned about possible hazards than the residents of Eurajoki. According to the cultural approach, these findings must be contextualized. Eurajoka, which holds more favorable attitudes than Kuhmo and Agnekoski, hosts a nuclear power plant. In the two other communities the opposition is greater, because the residents are unfamiliar with nuclear technology. The thesis of the paper is that in order to understand different opinions about the facility, one must understand the cultural logic of risk perception. People evaluate the risk as individuals, but also as members of different reference groups and in the context of local, national and international circumstances

    This paper reviews the approach taken to assess the social impacts of the proposed high-level nuclear waste repository at Yucca Mountain, Nevada on residents in the closest metropolitan area, Las Vegas. The purpose of this portion of the assessment is to investigate the effects of the repository on the future well-being and behavior of Las Vegas residents under different operational futures of the repository. To investigate these effects, a research design and conceptual framework were developed to collect data from a random sample of Las Vegas metropolitan area residents. The design allows for the collection of both baseline data (to determine current risk perceptions and behaviors) and projected effects of the repository under four different operational futures

    Industry can master risks but it cannot master the representations people have of these risks. This is why distortions may occur, as the public perceives risks where they are not, or in a totally deformed way. To deal with this type of situation which is dangerous in the long run, both for society and industry, it is necessary to study in detail where and how the difference between real risks and perceived risks is introduced. It then becomes possible to determine what means of action are available to manage the representations and the perceptions of risks. We shall mention two rather different examples of type of direct contact with the industrial reality; in France, we have determined policy of visits of nuclear sites (more than 10 000 people visit Cogema- la Hague site yearly), mainly addressed to school children and people living in the vicinity of the site. During these visits there is of course no question of explaining the detailed operation of the facility or the risks it generates. The purpose is to make the representation of the nuclear industry just as familiar as the representation of another large-scale technology tool: trains, dams,. In a different manner, missions are organised by Cogema - B.N.F.L.- O.R.C. (Overseas reprocessing Committee) to de dramatize the transport of high level vitrified wastes from Europe to Japan. these missions travel through those countries the ship come close to. Here, again, although the target is more the relays of opinion, the effective presence of specialized transport ship is a crucial element in putting a halt to phantasmic representations, as they are born from the remoteness of the object.

The first decade of the new millennium aspires to become the age of food safety, and once again, a major research effort is made to find out how consumers' confidence can be restored. Brewing......, as a particular branch of food manufacturing, has in the past been able to dodge implication in major risk debates.

    Since 1984, a significant amount of media attention has focused on health threats from radon gas exposure. Using a probability telephone survey of adults (n = 685), we studied public perceptions of risk from radon exposure versus other environmental health risks. The results indicated that 92% of those individuals who had heard of radon believe radon to be a health risk, although only 4% believe they are currently exposed to high levels of radon gas. Perception of risk from radon was positively related to other perceptions of environmental risks. Younger and less educated individuals were more likely to perceive radon as a health risk. Women were three-and-one-half times as likely as men to perceive risk from radon. However, there was no significant relationship between perceived risk from radon and cigarette smoking. Media attention has apparently led to public awareness of radon hazards, but further attention is needed to improve smokers' awareness of their special risks from radon

    Risk perception has an important influence on wildlife management and is particularly relevant to issues that present health risks, such as those associated with wildlife disease management. Knowledge of risk perceptions is useful to wildlife health professionals in developing communication messages that enhance public understanding of wildlife disease risks and that aim to increase public support for disease management. To promote knowledge of public understanding of disease risks in the context of wildlife disease management, we used a self-administered questionnaire mailed to a stratified random sample (n = 901) across the continental United States to accomplish three objectives: 1) assess zoonotic disease risk perceptions; 2) identify sociodemographic and social psychologic factors underlying these risk perceptions; and 3) examine the relationship between risk perception and agreement with wildlife disease management practices. Diseases we assessed in the surveys were rabies, plague, and West Nile virus. Risk perception, as measured by an index consisting of severity, susceptibility, and dread, was greatest for rabies and West Nile virus disease (x = 2.62 and 2.59, respectively, on a scale of 1 to 4 and least for plague (x = 2.39). The four most important variables associated with disease risk perception were gender, education, prior exposure to the disease, and concern for health effects. We found that stronger risk perception was associated with greater agreement with wildlife disease management. We found particular concern for the vulnerability of wildlife to zoonotic disease and for protection of wildlife health, indicating that stakeholders may be receptive to messages emphasizing the potential harm to wildlife from disease and to messages promoting One Health (i.e., those that emphasize the interdependence of human, domestic animal, wildlife, and ecosystem health).

  13. Wind speed perception and risk.

    Full Text Available BACKGROUND: How accurately do people perceive extreme wind speeds and how does that perception affect the perceived risk? Prior research on human-wind interaction has focused on comfort levels in urban settings or knock-down thresholds. No systematic experimental research has attempted to assess people's ability to estimate extreme wind speeds and perceptions of their associated risks. METHOD: We exposed 76 people to 10, 20, 30, 40, 50, and 60 mph (4.5, 8.9, 13.4, 17.9, 22.3, and 26.8 m/s winds in randomized orders and asked them to estimate wind speed and the corresponding risk they felt. RESULTS: Multilevel modeling showed that people were accurate at lower wind speeds but overestimated wind speeds at higher levels. Wind speed perceptions mediated the direct relationship between actual wind speeds and perceptions of risk (i.e., the greater the perceived wind speed, the greater the perceived risk. The number of tropical cyclones people had experienced moderated the strength of the actual-perceived wind speed relationship; consequently, mediation was stronger for people who had experienced fewer storms. CONCLUSION: These findings provide a clearer understanding of wind and risk perception, which can aid development of public policy solutions toward communicating the severity and risks associated with natural disasters.

Specific project goals are to synthesize information useful to utilities on noncombustion wastes, emphasize waste reduction as a priority over end-of-pipe management, develop methods to manage the costs and risks associated with noncombustion wastes (e.g., direct costs, permitting costs, liability costs, public relations costs), develop software and documentation to deliver the information and analysis methods to the industry. This project was initiated EPRI's Environment Division in late 1988. The early phases of the project involved gathering information on current noncombustion waste management practices, specific utility problems and concerns with respect to these wastes, current and potential future regulations, and current and emerging management options. Recent efforts have focused on characterizing the direct and indirect (e.g., lawsuits, remedial action) costs of managing these wastes and on developing and implementing risk management methods for a subset of wastes. The remainder of this paper describes the specific issues addressed by and the results and insights from the three completed waste-specific studies

  19. Assessment and perception of risk

    A recent two-day meeting was called by the Royal Society to discuss all types of risks, but symptomatic of the concerns of most of those present, the discussion centred mainly on the risks inherent in energy production and use. Among the subjects considered were public perception of differing risks, and how these are ranked, and risks versus benefits. Quotations from and summaries of many of the papers presented show that it was generally felt that scientists must be very careful in the way that they use numerical assessments of risk and that they should pay more attention than they have to social and political factors.

    There has lately been a greater responsivement in the media as well as the general public to the risk potential of high-frequency electromagnetic fields (EMF). If the discussion continues to gain momentum, this could have grave consequences for companies offering the products or services under attack. The working group Man, Environment, Technology (MUT) at Juelich Research Centre has examined the question of how EMF risks are valuated by the public. The study centered on the following questions: How are EMF risk potentials perceived by the public and what factors influence the public discussion? What future course might the discussion on risks take and what critical events and conditions deserve particular attention? The authors present and discuss the results of this first German study on product-inherent risks. (orig.) [de

  1. Industrial risk perceptions

    The risks of occupational exposure to radiation need fuller and more explicit characterization. They also need a more developed quantitative comparison with more familiar occupational hazards. To achieve this, some criterion is needed for establishing the amount of detriment one should attribute to different harmful effects, e.g., from accidents at work which cause death, temporary or permanent disability; from fatal and nonfatal cancers; from developmental abnormalities and any likely nonstochastic effects; and from a range of genetic defects. No such criterion for comparing incommensurable kinds of harm can be scientifically defined, but one is essential if occupational exposure standards are to be put into perspective. A comparison of the frequency of fatal cancers and severe genetic defects with that of accidental deaths at work is admittedly incomplete. One possible starting point is from a review of the average length of healthy life and activity lost as a result of nonfatal industrial accidents and some curable cancers, or of gross impairment during the course of an active disease or as a result of many types of genetic defect, or of life expectancy lost absolutely owing to fatal accidents and diseases. Estimates are discussed to emphasize the areas in which opinion is most needed to translate measures of risk based simply on total time lost into acceptable criteria of perceived detriment. Standards of industrial safety are reviewed on this basis, both for risk from accidents at work and from radiation exposure, with evidence on the rate at which both types of risk are being reduced

    The focus of this paper is on changes in perceptions of the risks associated with nuclear waste management over time. In particular, we are interested in the kinds of change that take place when the management programs, and those who are charged with implementing them, are subject to intensive public debate over an extended period of time. We are undertaken an over-time study of perceived risks in Colorado and New Mexico by implementing sequential random household surveys in each state, timed at six month intervals. This study employs three of these surveys, spanning the period from summer, 1990 to summer, 1991. Using these data, we examine the dynamics that may underlie variations in perceived risks over time. In particular, our analysis is focused on changes in the roles played by (1) basic political orientations (i.e. political ideology) and (2) trust in those who advocate conflicting policy positions

    A seismic event generally has consequences on the social relationships, economy and culture of the impacted territory. As Mary Douglas quotes, a change into the social perception of risk as consequence of an earthquake may have effects on the lifestyle of the local community. The above mentioned statement is the starting point of this article. illustrating the difference between peril and risk is the second point. According to the Aristotelian theory of categories, risk can be considered as a human characteristic depending on social and cultural factors. Risk is here intended as a social category and cannot be de facto reported as a statistical or stochastic function based on a mathematical formula, as long assumed in the past. This approach, then, requires a deep revision. In this sense, and following the concept of risk perception, seismic risk is analysed in this article in terms of impacts, precautionary measures, risk assessment and management. Knowledge of this topic cannot be intended as a simple philosophical exercise, since right on awareness depend risk reduction, humans and goods too [it

    Full Text Available We compare and critique two measures of risk perception. We suggest that a single question --- ``How risky is the situation?'' --- captures the concept of risk perception more accurately than the multiple-item measure used by Sitkin and Weingart (1995. In fact, this latter measure inadvertently captures notions of attractiveness or expected return, rather than risk perception. We further propose that the error underlying the construction of Sitkin and Weingart's measure is explained in terms of a top-down model of risk perception, in which perceived risk and perceived return are consequences, rather than determinants, of attractiveness. Two studies compare the validity of the two alternative measures.

  5. Risk perception and credibility of risk communication

    1992-10-01

    Experts and the public frequently disagree when it comes to risk assessment. The reasons for such disagreement are discussed, and it is pointed out that disagreement among experts and lack of full understanding of real risks contributes to skepticism among the public. The notion that people are in general reacting in a highly emotional and non-rational, phobic, manner is rejected. The very conditions for risk assessment present to the public, and common-sense cognitive dynamics, are better explanations of risk perception, as are some social psychological concepts. If trust is to be established in a country where it is quite low some kind of politically regulated public influence on decision making and risk monitoring is probably needed, e.g. by means of a publicly elected and responsible ombudsman. 57 refs, 8 figs, 5 tabs.

    In insurance science and natural science risks are defined as the expected extent of damages per time unit, i.e. risks are determined by empirical data representing the average number of people who incur damages in one year or one decade. In the social sciences the concept of risk is understood as the paragon of all unforeseeable consequences of an event or an action, or even plainly as the sum of things threatening our life and environment. Of course, the intuitive understanding of the concept is also of interest: what do people consider risky, how do they assess risks and how do they cope with risky situations. It is a chief task of interdisciplinary research to investigate the tension between the scientific and intuitive perception of risks and to develop political recommendations for those responsible for decision-making.

  9. Risk Perception and Social Amplification

    Smith, R.E.

    2001-01-01

    This paper seeks to consider social amplification as it applies to risk perception. Perceptions of the magnitude of a risk are conditioned by issues such as the degree of uncertainty in probability and consequences, the nature of the consequences and the relative weightings placed on probability and consequences. Risk perceptions are also influenced by factors such as confidence in the operator of an industrial process, trust in the regulator and the perceived fairness of regulatory decision-making. Different people may hold different views about these issues and there may also be difficulties in communication. The paper identifies and discusses self-reinforcing mechanisms, which will be labelled 'lock-in' here. They appear to apply in many situations where social amplification is observed. Historically, the term 'lock-in' has been applied mainly in the technological context but, in this paper, four types of lock-in are identified, namely scientific/technological, economic, social and institutional lock-in. One type of lock-in tends to lead to the next and all are buttressed by people's general acceptance of the familiar, fear of the unknown and resistance to change. The regulator seeks to make decisions which achieve the common good rather than supporting or perpetuating any set of vested interests. In this regard the locked-in positions of stakeholders, whether organisations, interest groups, or individual members of the public, are obstacles and challenges. Existing methods of consultation are unsatisfactory in terms of achieving a proper and productive level of dialogue with stakeholders

    The recognition of the societal dimension of risk assessment has been at the cradle of the opinion research on risks. Since risk estimates are not fixed by experts anymore, but are considered to show variation across a diverse population, the people themselves must be asked how they experience the risks. Following the rise in popularity of risk assessment and the recognition of its 'human' dimension, the demand for public opinion surveys on risks has been increasing at a fast pace. Unfortunately, this high demand sees some negative consequences. First, surveys are frequently conducted by people lacking even a minimal knowledge of survey methodology. In this respect, we might think of a journal or a newspaper trying to impress their readers with the definitive public opinion poll about the latest issue in vogue. Second, time pressure causes experienced or trained researchers to lower themselves to 'quick and dirty' work. While methodologically flawed opinion research might not be something to worry about when appearing in the amusement press, concern is due if the results of a survey inspire policy development. Indeed, when public opinion research is conceived as an instrument to support rational, evidence based public policy, the strictest methodological standards should be applied, even if it is clear that scientific research will never substitute political reasoning. This contribution deals with the safeguarding and enhancing of the quality of large scale surveys focusing on risk perception and related issues. This attention is relevant, not only for the reason that methodological standards may be flawed due to the immense popularity of the opinion poll, but also because the results of opinion surveys may have far-reaching policy consequences.

    Public perceptions about radioactive waste are generally rather or even strongly negative. They are also very poorly informed. This is rather unfortunate as it is these perceptions that appear to greatly influence the Public views on nuclear energy in general. This, in turn, has had an influence on political decisions. On the other hand, in a very clear majority of the Member States of the European Union, the Public have already indicated that they would be ready to accept the important role of nuclear in their future energy mix as long as all the radioactive wastes can be safely managed. However perceptions about nuclear energy and radioactive waste should be seen in the context of the Public wider perceptions on energy and, in particular, the role in the future of different sources. It may be wrong for political decisions on nuclear energy in the future to rely to heavily on the Public perceptions. (author)

  16. Risk decisions and nuclear waste

    Hansson, S.O.

    1987-11-01

    The risk concept is multidimensional, and much of its contents is lost in the conventional reduction to a unidimensional and quantifiable term. Eight major dimensions of the risk concept are discussed, among them the time factor and the lack-of-knowledge factor. The requirements of a rational discourse are discussed, in general and in relation to risk issues. It is concluded that no single method for the comparison and assessment of risks can be seen as the only rational method. Different methods can all be rational, although based on different values. Risk evaluations cannot be performed as expert assessments, divorced from the political decision process. Instead, risk evaluation must be seen as an essentially political process. Public participation is necessary in democratic decision-making on risks as well as on other issues. Important conclusions can be drawn for the management of nuclear waste, concerning specifications for the technical solution, the need for research on risk concepts, and the decision-making process.

    No public policy issue has been as difficult as high-level nuclear waste. Debates continue regarding Yucca Mountain as a disposal site, and-more generally-the appropriateness of geologic disposal and the need to act quickly. Previous research has focused on possible social, political, and economic consequences of a facility in Nevada. Impacts have been predicted to be potentially large and to emanate mainly from stigmatization of the region due to increased perceptions of risk. Analogous impacts from leaving waste at power plants have been either ignored or assumed to be negligible. This paper presents survey results on attitudes of residents in three counties where nuclear waste is currently stored. Topics include perceived risk, knowledge of nuclear waste and radiation, and impacts on jobs, tourism, and housing values from leaving waste on site. Results are similar to what has been reported for Nevada; the public is concerned about possible adverse effects from on-site storage of waste.

  18. Risk Assessment, Transparency and Public Perception

    To examine the US. public perception of risk now, in mid-2003, is a matter of capturing a snap shot at a particular moment of a specific circumstance. Over the past two years, Americans have gone from what they considered to be a fast-paced, high-stress, rapidly-changing, but fumiliar lifestyle and culture, to an uncertain existence that starts and stops with 'breaking news'. For people who previously felt confident about their understanding of what is or is not likely to happen, is or is not dangerous, and is or is not acceptable, there is now doubt. Studies of human behavior in judgement and decision making point out the importance of 'affect'. People's first reactions are based on good or bad experiences or images and not a rational weighing of pros and cons. The study results imply that people base their judgments of an activity or a technology not only on what they think about it but also on what they feel about it. It is unreasonable to expect that the public will accept decisions made for them regarding nuclear waste disposal and transport considering the negative images associated with radiation combined with the threat of possible terrorism. The federal government does face, as one of its most important tasks, protecting the health, safety and security of its people. it is also necessary for the government to consider the issue of nuclear waste disposal, but combining the two and using national security to defend nuclear waste policies is publically unacceptable. In a democracy, methods of how to best protect the people should be a matter of public debate and should be implemented only after public approval. One sure path to the erosion of democracy is govemmental decision making without the consent of the peopie, in the name of a (albeit honorable) principle. When government defends its own ideology and implements its own conception of what is best for the nation, democracy is lost

    The objective of this study is to examine risk taking and risk perception associations with perceived exertion, pacing, and performance in athletes. Two experiments were conducted in which risk perception was assessed using the domain-specific risk taking (DOSPERT) scale in 20 novice cyclists (experiment 1) and 32 experienced ultramarathon runners (experiment 2). In experiment 1, participants predicted their pace and then performed a 5-km maximum effort cycling time trial on a calibrated Kingcycle mounted bicycle. Split times and perceived exertion were recorded every kilometer. In experiment 2, each participant predicted their split times before running a 100-km ultramarathon. Split times and perceived exertion were recorded at seven checkpoints. In both experiments, higher and lower risk perception groups were created using median split of DOSPERT scores. In experiment 1, pace during the first kilometer was faster among lower risk perceivers compared with higher risk perceivers (t(18) = 2.0, P = 0.03) and faster among higher risk takers compared with lower risk takers (t(18) = 2.2, P = 0.02). Actual pace was slower than predicted pace during the first kilometer in both the higher risk perceivers (t(9) = -4.2, P = 0.001) and lower risk perceivers (t(9) = -1.8, P = 0.049). In experiment 2, pace during the first 36 km was faster among lower risk perceivers compared with higher risk perceivers (t(16) = 2.0, P = 0.03). Irrespective of risk perception group, actual pace was slower than predicted pace during the first 18 km (t(16) = 8.9, P risk perception groups. Initial pace is associated with an individual's perception of risk, with low perceptions of risk being associated with a faster starting pace. Large differences between predicted and actual pace suggest that the performance template lacks accuracy, perhaps indicating greater reliance on momentary pacing decisions rather than preplanned strategy.

    The Idaho National Engineering and Environmental Laboratory (INEEL) is investigating the development of a comprehensive and quantitative risk model framework for environmental management activities at the site. Included are waste management programs (high-level waste, transuranic waste, low-level waste, mixed low-level waste, spent nuclear fuel, and special nuclear materials), major environmental restoration efforts, major decontamination and decommissioning projects, and planned long-term stewardship activities. Two basic types of risk estimates are included: risks from environmental management activities, and long-term legacy risks from wastes/materials. Both types of risks are estimated using the Environment, Safety, and Health Risk Assessment Program (ESHRAP) developed at the INEEL. Given these two types of risk calculations, the following evaluations can be performed: risk evaluation of an entire program (covering waste/material as it now exists through disposal or other e nd states); risk comparisons of alternative programs or activities; comparisons of risk benefit versus risk cost for activities or entire programs; ranking of programs or activities by risk; ranking of wastes/materials by risk; evaluation of site risk changes with time as activities progress; and integrated performance measurement using indicators such as injury/death and exposure rates. This paper discusses the definition and calculation of legacy risk measures and associated issues. The legacy risk measure is needed to support three of the seven types of evaluations listed above: comparisons of risk benefit versus risk cost, ranking of wastes/materials by risk, and evaluation of site risk changes with time

    The communication of natural hazards and their consequences is one of the more relevant ethical issues faced by scientists. In the last years, social studies have provided evidence that risk communication is strongly influenced by the risk perception of people. In order to develop effective information and risk communication strategies, the perception of risks and the influencing factors should be known. A theory that offers an integrative approach to understanding and explaining risk perception is still missing. To explain risk perception, it is necessary to consider several perspectives: social, psychological and cultural perspectives and their interactions. This paper presents the results of the CATI survey on seismic risk perception in Italy, conducted by INGV researchers on funding by the DPC. We built a questionnaire to assess seismic risk perception, with a particular attention to compare hazard, vulnerability and exposure perception with the real data of the same factors. The Seismic Risk Perception Questionnaire (SRP-Q) is designed by semantic differential method, using opposite terms on a Likert scale to seven points. The questionnaire allows to obtain the scores of five risk indicators: Hazard, Exposure, Vulnerability, People and Community, Earthquake Phenomenon. The questionnaire was administered by telephone interview (C.A.T.I.) on a statistical sample at national level of over 4,000 people, in the period January -February 2015. Results show that risk perception seems be underestimated for all indicators considered. In particular scores of seismic Vulnerability factor are extremely low compared with house information data of the respondents. Other data collected by the questionnaire regard Earthquake information level, Sources of information, Earthquake occurrence with respect to other natural hazards, participation at risk reduction activities and level of involvement. Research on risk perception aims to aid risk analysis and policy-making by

    This study considers, in a geographical context, issues arising from the disposal of radioactive waste with particular emphasis on societal perceptions of Risk, Trust, NIMBYand Time. It establishes that the wider community now accepts the concepts of 'user pays' and offsetting compensation to any community that accepts a risk, such risk to be minimised and interruptible as necessary. The underlying causes of NIMBYism have been misjudged by industry and this work establishes that they are as much due to exclusion from the decision making process as they are to direct concerns about the social impact, health and environment. The principal cause of NIMBYism is discussed and a procedure to assist siting approval is suggested. This study establishes that industry, government authorities or specialists working alone in this field engender less trust by society than composite bodies including government departments, industry, environmentalists, health, science and society. The dimension of an individual's perception of forward time has been quantified and found to be much shorter than the time required for the isolation of radioactive waste. This research highlights the dynamic nature of all waste isolation processes and proposes a procedure that could render the concept of long term geological disposal more acceptable to the public. It evolved that the disposal of all waste is a dynamic process, the management of which must provide the time necessary for physical and chemical change and to ensure isolation from the biosphere while it remains hazardous. The outcome of this research is applicable to the disposal of all solid hazardous waste. (author)

  5. Stakeholder Perceptions of Risk in Construction

    Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders’ risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders’ varying judgments when considering injury prevention and hazard assessment.

    This publication reports and comments the results of a survey performed every 6 years on the perception of exposure to environmental risks. It notably comments the evolution between 2007 and 2013 of the perception of exposure to different types of risks: seismic risks, terrorism, major industrial risks, flooding risks, nuclear risks, food-related risks, risks related to climate change, unemployment, air pollution, and cancer. The perceptions of inhabitants of cities exposed or not exposed to some risks (industrial, climate, flooding) are compared. Risks are ranked from very important to not important at all. The influence of the existence of a risk when choosing to settle in a dwelling is also assessed, as well as the already lived consequences of catastrophes, the level of concern about possible consequences of a catastrophe, the respective roles of the State and citizen in the field of risk prevention, the opinions on law efficiency to protect people and goods, the knowledge of prevention arrangements against natural and technological risk, the level of confidence in public action regarding risks to which interviewed people are actually exposed (industrial risks, risks related to climate, flooding)

  9. Toxic urban waste's assault on cardiovascular risk

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available A cardiovascular health survey of 1203 persons in households located near the hazardous waste disposal sites and in a reference community, was conducted from 2009 until today to assess whether rates of adverse cardiovascular health outcomes were elevated among persons living near the sites. Data included medical records of reported cardiovascular disease certificates and hospital admission for cardiovascular diseases from hospital database. The study areas appeared similar with respect to mortality, cancer incidence, and pregnancy outcomes. In contrast, rate ratios were greater than 1.5 for 2 of 19 reported diseases, i.e., angina pectoris, and strokes. The apparent broad-based elevation in reported diseases and symptoms may reflect increased perception or recall of conditions by respondents living near the sites. Our study found that cardiovascular risk is associated only with PM2.5 concentrations, derived from uncontrolled burning of municipal solid waste in particular sites of our country. Their analysis demonstrated a relationship between increased levels of eventual fine particulate pollution and higher rates of death and complications from cardiovascular and cerebrovascular diseases. Management of solid waste releases a number of toxic substances, most in small quantities and at extremely low levels. Because of the wide range of pollutants, the different pathways of exposure, long-term low-level exposure, and the potential for synergism among the pollutants, concerns remain about potential health effects but there are many uncertainties involved in the assessment. Future community-based health studies should include medical and psychosocial assessment instruments sufficient to distinguish between changes in health status and effects of resident reporting tendency.

    Studies concerning the chemical risks of nuclear waste are reviewed. The radiological toxicity of the material is of primary concern but the potential nonradiological toxicity should not be overlooked as the chemotoxic substances may reach the biosphere from a nuclear waste repository. In the report is concluded that the possible chemotoxic effects of a repository for nuclear waste should be studied as a part of the formal risk assessment of the disposal concept. (author)

    The Waste Isolation Pilot Plant (WIPP) deep geological defense-generated transuranic radioactive waste (TRUW) repository in the United States was certified on the 13 of May 1998 and opened on the 26 of March 1999. Two sets of safety/performance assessment calculations supporting the certification of the WIPP TRUW repository show that the maximum annual individual committed effective dose will be 32 times lower than the regulatory limit and that the cumulative amount of radionuclide releases will be at least 10 times, more likely at least 20 times, lower than the regulatory limits. Yet, perceptions remain among the public that the WIPP TRUW repository imposes an unacceptable risk.

    2012-11-01

    Within research on individual variations in risk perception, personality has been suggested as one important factor. In the present study, personality traits (44 items from the Big Five inventory) were investigated in relation to risk perception in transport and transport behavioural adaptations. In a sample of 312 participants, we found that the personality trait 'emotional stability versus neuroticism' was negatively correlated with risk perception (operationalised as "thinking about the possibility") of an accident (-0.38) and an unpleasant incident, such as crime, violence, robbery (-0.25). 'Agreeableness' was also negatively related to risk perception, however first and foremost in relation to perceived risk for unpleasant incidents on transport modes in which one interacts with other people (0.25). Moreover, regression analyses showed that 'emotional stability' was a significant predictor of behavioural adaptations on bus. Regression analyses explained between 17 and 26 percent of variance in behavioural adaptations. The results show that different groups of people vary systematically in their perception of risk in transport. Furthermore, these differences are manifest as a difference in risk-preventive behaviour at a strategic level, i.e. as decisions about avoiding risky situations. Copyright © 2012 Elsevier Ltd.

    Waste poses a threat to public health and the environment if it is not stored, collected, and disposed of properly. The perception of waste as an unwanted material with no intrinsic value has dominated attitudes towards disposal. This study investigates the domestic waste practices, waste disposal, and perceptions about waste and health in an urban community. The study utilised a mixed-method approach. A cross-sectional survey questionnaire and in-depth interview were used to collect data. A total of 364 household heads were interviewed in the survey and six key informants were interviewed with the in-depth interviews. The results of the study revealed that 93.1% of households disposed of food debris as waste and 77.8% disposed of plastic materials as waste. The study also showed that 61.0% of the households disposed of their waste at community bins or had waste picked up at their homes by private contractors. The remaining 39.0% disposed of their waste in gutters, streets, holes and nearby bushes. Of those who paid for the services of private contractors, 62.9% were not satisfied with the services because of their cost and irregular collection. About 83% of the respondents were aware that improper waste management contributes to disease causation; most of the respondents thought that improper waste management could lead to malaria and diarrhoea. There was a general perception that children should be responsible for transporting waste from the households to dumping sites. Proper education of the public, the provision of more communal trash bins, and the collection of waste by private contractors could help prevent exposing the public in municipalities to diseases.

    Determining the differences in the perception of risks between experts who are regularly exposed to radiation, and lay people provides important insights into how potential hazards may be effectively communicated to the public. In the present study we examined lay people's (N = 1020) and experts' (N = 332) perception of five different radiological risks: nuclear waste, medical x-rays, natural radiation, an accident at a nuclear installation in general, and the Fukushima accident in particular. In order to link risk perception with risk communication, media reporting about radiation risks is analysed using quantitative and qualitative content analyses. The results showed that experts perceive radiological risks differently from the general public. Experts' perception of medical X-rays and natural radiation is significantly higher than in general population, while for nuclear waste and an accident at a nuclear installation, experts have lower risk perception than the general population. In-depth research is conducted for a group of workers that received an effective dose higher than 0.5 mSv in the year before the study; for this group we identify predictors of risk perception. The results clearly show that mass media don't use the same language as technical experts in addressing radiological risks. The study demonstrates that the discrepancy in risk perception and the communication gap between the experts and the general population presents a big challenge in understanding each other

    The necessity for research and development of risk analysis methods arise from practical needs for safety for men and environment. Relating to speed of technological development risk is implemented in modern technological achievements. Complexity of approach to the concept of risk presents the essence of risk management. Risk management means to apply risk analysis in order to risk decrease and control. Database for risk management is in technical social, economic and political area. Risk perception is a construction in the field of social psychology i.e. public opinion research. These results are of importance for the risk management. Research presented in this paper has been done on the sample of 240 examines with two basic sub samples: person working with ionizing radiation (140 of them) and persons not working with ionizing radiation (100 of them). Attitudes to risk definition risk acceptance and relation to risk consequences. (author)

    The aim of this study is a quantification of public risk perception towards the nuclear field so as to be considered in decision making whenever the public involvement is sought. The proposed model includes both qualitative factors such as familiarity and voluntariness and numerical factors influencing risk perception, such as probability of occurrence and severity of consequence. Since part of these factors can be characterized only by qualitative expressions and the determination of them are linked with vagueness, imprecision and uncertainty, the most suitable method for the risk level assessment is Fuzzy Logic, which models qualitative aspects of knowledge and reasoning processes without employing precise quantitative analyses. This work, then, offers a Fuzzy-Logic based mean of representing the risk perception by a single numerical feature, which can be weighted and accounted for in decision making procedures. (author)

    Many researches on risk perception have often been concerned with reaction of the public to modern technology. A major concern is the public fear of such new technology as nuclear power and genetic engineering. When the perceived risk was examined using a risk ranking technique, Japanese school teachers, university students and also NIRS staffs (female clerical staffs and researchers) viewed nuclear power to be much riskier than the objective estimation. Many technical experts have believed that this great fear results from an overestimation of risk by the public due to lack of scientific knowledge. So far, several studies reported the results to examine the correlation of the perception of some risk sources with knowledge about them, although their conclusions are inconsistent. When the perceived risk by trainees on a radiation protection course in NIRS was examined, nuclear power was rated as the second and 14th among 30 risk items by those who majored in life sciences in college and by those in physics, chemistry or technology, respectively. The perceived risk of nuclear power did not change among trainees by training offered fundamental knowledge about radiation during the course. On the other hand, the orders of smoking and alcoholic beverages rose considerably. Our results are consistent with the previous reports, i.e., what people learn initially about risk source has more important role in risk perception than what they learn later, and the increase of perceived risk is more easier than its decrease. Knowledge is now recognized as one of the factors which influence on risk perception. However, a special emphasis is now placed on risk communication in order to make partnership between communicators and receivers in the risk management. (author)

    Risk is generally defined as the "combination of the probability of the occurrence of an event and its negative consequences" ( UNISDR, 2009). However, the perception of a risk differs among cultures regarding different features such as the context,causes, benefits or damage. Risk perception is the subjective valuation of the probability of an event happening and how concerned individuals or groups are with the consequences (Sjöberg, 2004). Our study is based on an existing framework for risk perception (Rehn and Rohrmann, 2000). We analyse the characteristics of the risk perception regarding extreme events (e.g.droughts) and how the perception of the group drives the action to manage the risk. We do this to achieve an overview of the conditions that let stakeholders join each other to improve risk management especially when governments are not reacting properly. For our research, attention is paid on risk perception of Multi-Sector Partnerships not taking into account the individual level of risk perception. We focus on those factors that make risk management effective and increase resilience. Multi-Sector Partnerships, considered as significant governance structures for risk management, might contribute to reduce vulnerability in prone areas to natural hazards and disasters. The Multi-Sector Partnerships used for our research are existing partnerships identified in the cases studies of the European project ENHANCE. We implement a survey to analyse the perception of risk in the case studies. That survey is based on the Cultural Theory (Douglas and Wildavsky, 1982)and the Protection Motivation Theory (Rogers, 1975). We analyse the results using the Qualitative-Comparative Analysis proposed by Ragin in 1987. The results show the main characteristics of a risk culture that are beneficial to manage a risk. Those characteristics are shaped by the perception of risk of the people involved in the partnership, which in turn shapes their risk management. Nevertheless, we

    A systematic Risk Assessment was performed to identify the technical, regulatory, and programmatic uncertainties and to quantify the risks to the Hanford Site double-shell tank waste vitrification program baseline (as defined in December 1990). Mitigating strategies to reduce the overall program risk were proposed. All major program elements were evaluated, including double-shell tank waste characterization, Tank Farms, retrieval, pretreatment, vitrification, and grouting. Computer-based techniques were used to quantify risks to proceeding with construction of the Hanford Waste Vitrification Plant on the present baseline schedule. Risks to the potential vitrification of single-shell tank wastes and cesium and strontium capsules were also assessed. 62 refs., 38 figs., 26 tabs

    This paper describes methods for evaluating perception-based economic impacts resulting from siting hazardous waste facilities. Socioeconomic impact analysis has devoted increasing attention to the potential implications of changed public perceptions of risk due to an activity or situation. This contrasts with traditional socioecconomic impact analysis, which has been limited to measuring direct and indirect consequences of activities, e.g., the employment effects of placing a military base in a specified location. Approaches to estimating economic impacts due to changes in public perceptions are ex ante or ex post. The former predict impacts prior to the construction and operation of a facility, while the later is based on impacts that become evident only when the facility is up and running. The theoretical foundations and practical requirements for demonstrating impacts, resulting from the siting of a hazardous facility are described. The theoretical rationale supporting the study of perceived risk research is presented along with discussion of problems that arise in demonstrating the existence and measuring the quantitative importance of economic impacts due to changes in perceived risk. The high-level nuclear waste facility being considered in Nevada is presented as an example in which there is potential for impacts, but where the link between perceived risk and economic conditions has not yet been developed

    Full Text Available Ruth Webster1, Emma Heeley21Cardiovascular Division, 2Neurological and Mental Health Division, The George Institute for International Health, Camperdown, NSW, AustraliaAbstract: Cardiovascular disease (CVD is still the leading cause of death and disability worldwide despite the availability of well-established and effective preventive options. Accurate perception of a patient’s risk by both the patient and the doctors is important as this is one of the components that determine health-related behavior. Doctors tend to not use cardiovascular (CV risk calculators and underestimate the absolute CV risk of their patients. Patients show optimistic bias when considering their own risk and consistently underestimate it. Poor patient health literacy and numeracy must be considered when thinking about this problem. Patients must possess a reasonably high level of understanding of numerical processes when doctors discuss risk, a level that is not possessed by large numbers of the population. In order to overcome this barrier, doctors need to utilize various tools including the appropriate use of visual aids to accurately communicate risk with their patients. Any intervention has been shown to be better than nothing in improving health understanding. The simple process of repeatedly conveying risk information to a patient has been shown to improve accuracy of risk perception. Doctors need to take responsibility for the accurate assessment and effective communication of CV risk in their patients in order to improve patient uptake of cardioprotective lifestyle choices and preventive medications.Keywords: risk perception, cardiovascular disease, cardioprotective lifestyle

    An implicit assumption of risk perception studies is that concerns expressed in questionnaires reflect concerns in everyday life. The aim of the present study is to check this assumption, i.e., the extrapolability of risk perceptions expressed in a survey, to risk perceptions in everyday life. To that end, risk perceptions were measured by a multidimensional approach. In addition to the traditional focus on measuring the magnitude of risk perceptions, the thematic relevance (how often people think about a risk issue) and the discursive relevance (how often people think about or discuss a risk issue) of risk perceptions were also collected. Taking into account this extended view of risk perception, an online survey was conducted in six European countries with 2454 respondents, referring to radio frequency electromagnetic field (RF EMF) risk potentials from base stations, and access points, such as WiFi routers and cell phones. The findings reveal that the present study's multidimensional approach to measuring risk perception provides a more differentiated understanding of RF EMF risk perception. High levels of concerns expressed in questionnaires do not automatically imply that these concerns are thematically relevant in everyday life. We use thematic relevance to distinguish between enduringly concerned (high concern according to both questionnaire and thematic relevance) and not enduringly concerned participants (high concern according to questionnaire but no thematic relevance). Furthermore, we provide data for the empirical value of this distinction: Compared to other participants, enduringly concerned subjects consider radio frequency electromagnetic field exposure to a greater extent as a moral and affective issue. They also see themselves as highly exposed to radio frequency electromagnetic fields. However, despite these differences, subjects with high levels of thematic relevance are nevertheless sensitive to exposure reduction as a means for improving the

    Risk perception is a subjective assessment of the actual or potential threat to one's life or, more broadly, to one's psychological well-being. Given the various risks associated with later life, a valid and reliable integrative screening tool for assessing risk perception among the elderly is warranted. The study examined the psychometric properties and factor structure of a new integrative risk perception instrument, the Perceived Risk Scale. This eight-item measure refers to various risks simultaneously, including terror, health issues, traffic accidents, violence, and financial loss, and was developed specifically for older adults. An online survey was conducted with 306 participants aged 50 years and older. The scale was examined using exploratory factor analysis and concurrent validity testing. Factor analysis revealed a two-factor structure: later-life risks and terror risks A high percentage of explained variance, as well as internal consistency, was found for the entire scale and for both factors. Concurrent validity was supported by significant positive associations with participants' depression and negative correlations with their life satisfaction. These findings suggest that the Perceived Risk Scale is internally reliable, valid, and appropriate for evaluating risk perception in later life. The scale's potential applications are discussed. © The Author(s) 2016.

    A framework for relating the variables involved in the public perception of hazardous materials transportation is presented in which perceived risk was described in six basic terms: technical feasibility, political palatability, social responsibility, benefit assessment, media interpretation, and familiarity as a function of time. Scientists, the media and public officials contribute to the discussion of risks but ultimately people will decide for themselves how they feel and what they think. It is not sufficient to consider the public of not being enlightened enough to participate in the formulation of radioactive material transport policy. The framework provides the technologist with an initial formulation to better inform the public and to understand public perception

    A recent two-day meeting was called by the Royal Society to discuss all types of risks, but symptomatic of the concerns of most of those present, the discussion centred mainly on the risks inherent in energy production and use. Among the subjects considered were public perception of differing risks, and how these are ranked, and risks versus benefits. Quotations from and summaries of many of the papers presented show that it was generally felt that scientists must be very careful in the way that they use numerical assessments of risk and that they should pay more attention than they have to social and political factors.

  18. Public perception of radioactive waste management and lessons learned

    Energy Technology Data Exchange (ETDEWEB)

    Curd, Peter James [UK Nirex Ltd., Harwell, Didcot (United Kingdom)

    1989-07-01

    This paper reviews the background to the current public awareness campaign on the management of radioactive wastes, which culminated in the publication by UK Nirex Limited of a Discussion Document 'The Way Forward'. The lessons learned from previous confrontations with communities and pressure groups are outlined together with the philosophy behind the Company's comprehensive discussion programme. An open policy of information distribution, while necessary was not enough. Therefore previous Nirex public information programmes had been less successful than hoped. Much has been learned from the problems encountered and this has been applied to develop a new programme. The importance of inviting people to take part in the decision process is manifest, and the discussion process was designed to encourage participation. It was an important step in overcoming the perception of secrecy which still surrounds the nuclear industry as a whole. It was unlikely that many communities would volunteer to take responsibility for the nations nuclear waste, although there are encouraging signs that some communities see the potential benefits outweigh perceived risks. However, by actively airing the matter in the general absence of local controversy a lot of accurate and hopefully persuasive information has been passed to many people and organisations in an atmosphere conducive to gaining their attention. If the Nirex discussion programme achieved nothing else there should be no local authority in the United Kingdom who does not know who we are, what we are doing and why. Having made a good start it is essential that an open debate continues and that local communities continue to share in the decision making process. There will be problems to overcome especially where unpopular recommendations have to be made but Nirex will continue to make every effort to win confidence and support by deeds as well as words.

  20. Lay and expert perceptions of zoonotic risks

    2005-01-01

    As in many other areas, there is a divide between lay and expert perceptions of risk within the food sector, and this can lead to disagreement over priorities in food risk management. The risk perception literature tends to stress that the parties involved in this disagreement have different...... concepts of risk and hence are bound more or less to talk at cross-purposes. This paper suggests an alternative analysis: In the light of moral theory, the conflicting perspectives can be understood as a genuine moral conflict. When this conflict is conceptualised, a rational dialogue becomes possible....... The paper reports a series of qualitative interviews with lay people and experts on zoonotic food risks. The interviews are used to reconstruct the values underlying some of the dominant perspectives. The conflict between these stylised perspectives is then analysed with the help of moral theory. Finally...

  1. The Role of risk perception for risk management

    International Nuclear Information System (INIS)

    Renn, Ortwin

    1999-01-01

    The list of individual and social factors that shape risk perception demonstrates that the intuitive understanding of risk is a multidimensional concept and cannot be reduced to the product of probabilities and consequences. Although risk perceptions differ considerably among social and cultural groups, the multi-dimensionality of risk and the integration of beliefs related to risk, the cause of risk, and its circumstances into a consistent belief system appear to be common characteristics of public risk perception in almost all countries in which such studies have been performed. Furthermore, the experience of risk is not limited to the threat of facing harm in the future. It includes subjective predictions of possible outcomes, the social and cultural context in which the risk is experienced, the mental images the risk situation evokes, the perception of the players who are involved in the risk situation and the judgments about fairness and equity related to the distribution of potential hazardous events. In this sense, risk is a social construct rather than a physical entity. Risk communication and conflict resolution is therefore a crucial element of any risk management strategy. The goal of risk communication and conflict resolution should not be to persuade people to accept whatever the communicator thinks is best for them. The ideal communication program envisions a receiver who processes all the available information to form a well-balanced judgement in accordance with the factual evidence, the arguments of all sides, and his/her own interests and preferences. The ultimate goal of risk communication is to reconcile expertise, interests, and public preferences. (EHS)

    2000-01-01

    The fact that the risks deriving from different activities involving the same radiation exposure are seen very differently by a single population is a highly significant one. Exactly identical risks are considered oppositely, depending on the origin of radiation (whether produced by medical applications or by nuclear power plants, resulting from natural radiation or from artificial radiation). It appears as if there was good radiation and bad radiation..! One of the purposes of the paper is the discussion of causes. The acceptance of a given risk by a certain section of the population is closely related to the benefits that the group expects to receive-either consciously or unconsciously-from the activity producing the risk. Consequently, an analysis of the factors influencing the eventual rejection of a practice should explore not only fears, but also hopes...! On the basis of a risk-perception survey carried out in a population sector attending hospitals-including both patients and physicians-, a prior objective analysis of the results obtained was performed and, later on, the various statements by those surveyed were studied. The design of the survey allowed for a comparative assessment of the perception of different risks depending on the people's educational and social level. An epistemological study was made on the validity involved in the use of the data resulting from the survey, so as to reach different conclusions. The population's opinion about the capacity for response, the qualification and the mitigation means available to the State authorities in order to face an eventual radiological emergency plays a leading role in risk perception. In an analysis of the relevant factors involved in risk and benefits perception by the population (in the real world), attention must be paid to the existence of organized opinion groups representing the interest of a given sector. Of course, the population's confidence in the experts providing the information is a key

    Although the results of this paper are based on some restrictive assumptions and a limited amount of data, the authors nevertheless feel that they form a starting point for some new insights into the difficult problem of how to compare risks that have different characteristics. Today almost all regulatory agencies are facing the difficult question of ''how safe is safe enough.''. Although risk conversion factors may be able to play a useful role in setting safety criteria, it must also be recognized that RCFs as developed here are only a part of what needs to be considered. The RCFs involve only risk comparisons, whereas a safety criterion must surely include not only risk but cost and benefit as well

    The purpose of this paper is to present our main results from a survey carried out in Spain in the context of social risk perception. This survey is included in a broad project (PRISP) sponsored by the UE and the national Civil Protection Service, and carried out simultaneously in three countries: Spain, Italy and UK. The project combined qualitative and quantitative assessment methods, although only survey results are presented here. A random sample of 600 subjects from two different Spanish communities close to a COMAH chemical site was selected for the research. Main findings regarding, differential perception between both community populations, sex differences, and 'bias perception' of risks among others have been achieved. Main dimensions were obtained by multidimensional scaling and Factor Analysis. Dimensions reported here are similar to the usual findings from the psychometric paradigm. (authors)

    Radiation protection training and general employee training within the nuclear industry are designed to reduce workers' concerns about radiation and to develop skills that will protect against unwarranted exposures. Inaccurate perceptions about radiation by workers can cause a lack of adequate concern or exaggerated fears, which in turn can result in unnecessary radiation exposure to the worker or co-workers. The purpose of the study is threefold: (a) to identify health and safety concerns among nuclear power plant employees, (b) to discover variables that influence the perception of risk among employees, and (c) to ascertain if attitudes of the family, community, and the media affect workers' perception of risk. Workers identified five areas of concern: shift work, radiation, industrial safety, stress, and sabotage

Through empirical examples derived from our research and other studies, we show that fishermen’s risk perception can be explained...... by the need to adopt coping strategies, ie compromises and resilience in an environment marked by uncertainty and unpredictability. The difference between lay and expert knowledge is particularly salient in the case of safety researchers and fishermen. In order to make sense of the fishermen’s risk perception......In this paper we reflect on the possible reasons for the acceptability of risk in sea fishing and the implications they may have for safety actions and interventions.

    The Tank Waste Remedation System (TWRS) Risk Management List and it's subset of critical risks, the Critical Risk Management List, provide a tool to senior RL and WHC management (Level-1 and -2) to manage programmatic risks that may significantly impact the TWRS program. The programmatic risks include cost, schedule, and performance risks. Performance risk includes technical risk, supportability risk (such as maintainability and availability), and external risk (i.e., beyond program control, for example, changes in regulations). The risk information includes a description, its impacts, as evaluation of the likelihood, consequences and risk value, possible mitigating actions, and responsible RL and WHC managers. The issues that typically form the basis for the risks are presented in a separate table and the affected functions are provided on the management lists

    The problems in the field of risk to inform the public are the difference in the risk perception by the public, between the risk realities and the image the public makes in himself, the confidence of the public towards those that give information, the readability ( and then understanding) of the information, the easiness for the public to forget the information. Solutions can be summarized by the same way: durability of information actions, information elaborated by safety authority, inhabitants associations, risk generator, elected members, supports of information clear and understandable.

    Full text of publication follows: what is natural? And what is Nature? Are perceptions of Nature and naturalness related to perceptions of risk? This paper focuses on these aspects based on results from a Swedish representative sample (N=731), where subjects indicated e.g. the degree of naturalness of various phenomena, their views of nature, and personal life values, as well as perceptions of risk in specified contexts. The results showed a tendency to perceive as natural the phenomenon which is positively valued, i.e. what is natural is also good or desirable. Further, there were weak correlations between perceived naturalness and indicators of technological optimism, possibly indicating that persons with a more generous view of what is natural also more easily might accept change and outcomes due to human intelligence and activity. The construct of 'tampering with nature' has previously been shown to be one good predictor of perceived risk. The respondents also rated their agreement with items aimed to reflect the four 'views of nature' as suggested by Cultural Theory, i.e. nature as robust, capricious, tolerant and fragile. Nature was foremost perceived as fragile, but the main result clearly revealed that peoples' views of nature were complex and most often involved several of the suggested categories. The discussion focuses on the possible implications on environmental concern and risk perception given that Nature would develop into an undesirable type of locality. (author)

  16. Some approaches to understanding public perceptions of risk

    International Nuclear Information System (INIS)

    Greer-Wootten, B.

    1981-01-01

    The debate on nuclear power contains a central set of arguments that can be related, by and large, to differences in the meaning of risk assessment for various concerned publics. At an earlier point in time the arguments largely concerned power production (reactor safety), but now most components of the nuclear fuel cycle are subject to risk perceptions. The strongest levels of public concern over time have focussed on waste management, and in this area illustrates most clearly the gaps between the assessments of the technical community and those of the publics. In order to understand such gaps, a theoretical framework is necessary. The broadest scope for such a framework is found in the I.I.A.S.A. - I.A.E.A. model developed by H.J. Otway, with its three interrelated components of risk estimation (technical), risk evaluation (public) and risk management. The model is described in this paper, as well as a number of empirical studies that derive from it and attempt to measure public perceptions of risks. These studies are then compared to several alternative explanations: the use of public opinion surveys; risk rating tasks based on psychologicl theory; the structure of arguments used by members of the public in qualitative focus group discussions; and a model of local community conflict derived from the content analysis of newspapers. Throughout the discussion, examples are taken wherever possible, from recent Canadian studies, in which the effects of major incidents (such as T.M.I., the Mississauga derailment, the Blind River refinery siting controversy, etc.) become apparent. It is suggested that our understanding of public perceptions of risks cannot be divorced from the set of broad societal concerns evidenced in the I.I.A.S.A. - I.A.E.A. model, and that the crucial elements of this approach are seen in its emphasis on the decision-making process

    The initial phase of the work performed during FY 1977 consisted of performing a ''scoping'' study to define issues, determine an optimal methodology for their resolution, and compile a data base for acceptable risk criteria development. The issues, spanning technical, psychological, and ethical dimensions, were categorized in seven major areas: (1) unplanned or accidental events, (2) present vs future risks, (3) institutional controls and retrievability, (4) dose-response mechanism and uncertainty, (5) spatial distribution of exposed populations, (6) different types of nuclear wastes, and (7) public perception. The optimum methodology for developing ARC was determined to be multi-attribute decision analysis encompassing numerous specific techniques for choosing, from among several alternatives, the optimal course of action when the alternatives are constrained to meet specified attributes. The data base developed during the study comprises existing regulations and guidelines, maximum permissible dose, natural geologic hazards, nonradioactive hazardous waste practices, bioethical perspectives, and data from an opinion survey

    The sanitary waste represents a potential hazard for health workers. Given the high risk of infection in labor accidents, the correct management of sanitary waste minimizes this risk and improves labor and environment conditions. To identify risk perception with health professionals in relation to the advanced sorting and management of healthcare waste (HW). The current study is a descriptive, cross-sectional. The sample size was 177 health workers (nurse assistants, nurses, physicians, lab technicians) from three hospitals in Barcelona (Catalonia). Homemade questionnaire and questions with a free and spontaneous association and incomplete sentences were used to analyze labor variables, perception of risk and personal security through a Likert scale. Using a score from 1 (the lowest perception of risk) to 5 (the high perception of risk) to assess the risk perception, the average value for nurse assistants, nurses, physicians, and lab technicians was 3.71, 3.75, 3.83 and 4.03, respectively. Referring to items with free and spontaneous response association, 44.8% of workers consider HW as a biohazard, 29.6% consider it as waste material, 22.1% state that it must be managed properly and 3.5% described it as unknown residues. The results suggest that all health professionals generally have a perception of high risk. The lab technicians have a higher perception of the real risk of inadequate management of HW A 63.2% report that everyone has to make a proper management to preserve their occupational health; the 59% consider that the HW are a biological risk to the general population and only the 47.8% that are harmful to public health. Although it should be noted that only 44.8% think that HW are toxic and dangerous.

    1998-01-01

    This article is an outgrowth of the opening article given at a pair of invited sessions on 'Risk Perception versus Risk Analysis' at the PSAM 3 Conference held on Crete in June 1996. The first introductory section provides some review of the relevant issues and raises some general questions about possible changes in the emphasis and directions of research on risk perception and related social science studies. The second section looks in a little more detail at issues related to public participation in the deliberations and decision-making concerning significant societal ventures involving risk. Section 3 examines the role and importance of knowledge in risk perception. the relatively brief fourth section raises questions about the public's perception of geologic disposal of high-level radioactive wastes as something catastrophic, to be 'dreaded'. Section 5 looks at the bases for allocation of resources for improving the public health and safety. And the sixth section examines intragenerational equity and the conflict which can arise between it and intergenerational equity

    Full Text Available Jarosite waste, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many tailing damps has become a major ecological concern. Three different methods, namely modified Synthetic Precipitation Leaching Procedure (SPLP, three-stage BCR sequential extraction procedure and Potential Ecological Risk Index (PERI Method were used to access the ecological risk of jarosite waste disposal in Mitrovica Industrial Park, Kosovo. The combination of these methods can effectively identify the comprehensive and single pollution levels of heavy metals such as Zn, Pb, Cd, Cu, Ni and As present in jarosite waste. Moreover, the great positive relevance between leaching behavior of heavy metals and F1 fraction was supported by principal component analysis (PCA. PERI results indicate that Cd showed a very high risk class to the environment. The ecological risk of heavy metals declines in the following order: Cd>Zn>Cu>Pb>Ni>As.

  3. The social perception of risk

    International Nuclear Information System (INIS)

    Eiser, J.R.

    1989-01-01

    Much research on acceptance of risks implies a distinction between objective and subjective definitions of risk. This paper disputes this distinction, arguing instead that discrepancies between public and 'expert' views are to be better understood in terms of differences in how decisions are seen to be made. Risk is a product of decisions taken in response to environmental events, and depends not simply on the threat posed by such events but on the quality of the decisions. A model of decision quality is presented, derived from signal detection theory, which distinguishes between the ability to discriminate between different kinds of events, and the criterion, or level of certainty that is required before a particular response is chosen. Whereas discrimination ability depends on the expertise of decision-makers and the predictability of the events in question, the response criterion reflects considerations of costs, benefits and equity. Where the cost of overlooking a real threat ('false-negative' response) is high, a cautious criterion may be demanded. Where discrimination ability is also seen to be low, the chance of 'false-negatives' may only be adequately reduced at the price of a large number of 'false-positives', or 'unnecessary' protective responses against imagined threats. In extreme cases, this may amount to total opposition to the operation of a system. (author)

    The purpose of the Tank Waste Remediation System (TWRS) Risk Management Plan is to describe a consistent approach to risk management such that TWRS Project risks are identified and managed to achieve TWRS Project success. The Risk Management Plan implements the requirements of the Tank Waste Remediation System Systems Engineering Management Plan in the area of risk management. Figure ES-1 shows the relationship of the TWRS Risk Management Plan to other major TWRS Project documents. As the figure indicates, the Risk Management Plan is a tool used to develop and control TWRS Project work. It provides guidance on how TWRS Project risks will be assessed, analyzed, and handled, and it specifies format and content for the risk management lists, which are a primary product of the risk management process. In many instances, the Risk Management Plan references the TWRS Risk Management Procedure, which provides more detailed discussion of many risk management activities. The TWRS Risk Management Plan describes an ongoing program within the TWRS Project. The Risk Management Plan also provides guidance in support of the TWRS Readiness To-Proceed (RTP) assessment package

The text is divided into three parts: In the first part it tells the story of the black plague pandemic during the XIV century, showing how this disease was associated with the residues produced by the human body. In the second part it explains how the first notions of waste were, and still are, related to dirt, disease and death. Finally, in the third part, it describes the first measures of hygiene in the Renaissance and refers to the first public health actions at the beginning of the XX century, starting to combat the agents of infectious diseases and their vectors.

    Research has identified a number of risk factors for road traffic accidents. Some of these require education of drivers and a first step in this process is to assess perceptions of these risk factors to determine the current level of awareness. An online survey examined risk perception with the focus being on driver behavior, risk taking and fatigue. The results showed that drivers’ perceptions of the risk from being fatigued was lower than the perceived risk from the other factors.

    Full Text Available Recycling is viewed as a central aspect in sustainability and mainly as pro-environmental consumer behavior. The purpose of this study is to examine the perception of households on financial incentives in endorsing sustainable recycling for municipal solid waste in Nigeria. The study was conducted in the Shomolu Local Government Area, Lagos State, Nigeria. The study also covers drivers for household willingness to recycle municipal solid waste on environmental risk, behavioral economics, resource value, economic benefit, convenience, knowledge, legislation, and belief. The result from the study asserts the hypothesis that financial incentives for recycling are vital for reducing and managing municipal solid waste sustainably. The most important driver for household willingness to recycle municipal solid waste is the detrimental environmental impacts. A moderate to positive relationship exists between households’ perception of financial incentives for recycling and drivers for household willingness to recycle municipal solid waste. The study recommends adopting the extended producer responsibility (EPR model, reverse vending options, amongst other approaches, in an effort to promote recycling culture among citizens and residents in Nigeria.

Debates continue regarding Yucca Mountain as a disposal site, and - more generally - the appropriateness of geologic disposal and the need to act quickly. Previous research has focused on possible social, political, and economic consequences of a facility in Nevada. Impacts have been predicted to be potentially large and to emanate mainly from stigmatization of the region due to increased perceptions of risk. Analogous impacts from leaving waste at power plants have been either ignored or assumed to be negligible. This paper presents survey results on attitudes of residents in three countries where nuclear waste is currently stored. Topics include perceived risk, knowledge of nuclear waste and radiation, and impacts on jobs, tourism, and housing values from leaving waste on site. Results are similar to what has been reported for Nevada; the public is concerned about possible adverse effects from on-site storage of waste. 24 refs., 7 figs., 5 tabs

    This study analyzes cattle farmers’ perceptions of risk and risk management strategies in Tigray, Northern Ethiopia. We use survey data from a sample of 356 farmers based on multistage random sampling. Factor analysis is employed to classify scores of risk and management strategies, and multiple...... utilization were perceived as the most important strategies for managing risks. Livestock disease and labor shortage were perceived as less of a risk by farmers who adopted the practice of zero grazing compared to other farmers, pointing to the potential of this practice for risk reduction. We find strong...... evidence that farmers engage in multiple risk management practices in order to reduce losses from cattle morbidity and mortality. The results suggest that government strategies that aim at reducing farmers’ risk need to be tailored to specific farm and farmer characteristics. Findings from this study have...

    This study examines the perceived risks to forest biodiversity and perceived effectiveness of biodiversity conservation strategies among the general public. It tests the hypotheses that perceived risk to forest biodiversity is influenced by cognitive factors (value orientation and knowledge) and social-cultural factors (such as gender and environmental membership) and that risk perceptions influence other cognitive constructs such as support for natural resource policy and management. Data were collected from a sample of the general public (n= 596) in British Columbia, Canada by mail survey in 2001. Results show that insects and disease were perceived as the greatest risk. Educating the public and industry about biodiversity issues was perceived as a more effective conservation strategy than restricting human uses of the forest. Value orientation was a better predictor of perceptions of risk and perceived effectiveness of conservation strategies than knowledge indicators or social-cultural variables. Examining the indirect effects of social-cultural variables, however, revealed that value orientation may amplify the effect of these variables and suggests that alternative paths of influence should be included. Perceived risk showed an inconsistent association with perceived effectiveness of conservation strategies.

    Background Subjective risk factor perception is an important component of the motivation to change unhealthy life styles. While prior studies assessed cardiovascular risk factor knowledge, little is known about determinants of the individual perception of stroke risk. Methods Survey by mailed questionnaire among 1483 participants of a prior public stroke campaign in Germany. Participants had been informed about their individual stroke risk based on the Framingham stroke risk score. Stroke risk factor knowledge, perception of lifetime stroke risk and risk factor status were included in the questionnaire, and the determinants of good risk factor knowledge and high stroke risk perception were identified using logistic regression models. Results Overall stroke risk factor knowledge was good with 67–96% of the participants recognizing established risk factors. The two exceptions were diabetes (recognized by 49%) and myocardial infarction (57%). Knowledge of a specific factor was superior among those affected by it. 13% of all participants considered themselves of having a high stroke risk, 55% indicated a moderate risk. All major risk factors contributed significantly to the perception of being at high stroke risk, but the effects of age, sex and education were non-significant. Poor self-rated health was additionally associated with high individual stroke risk perception. Conclusion Stroke risk factor knowledge was high in this study. The self perception of an increased stroke risk was associated with established risk factors as well as low perception of general health. PMID:17371603

    Three fundamental questions concerning public perception of the measurement of radioactive wastes were addressed in this report. The first question centered on the perceived importance of nuclear waste management as a public issue: how important is nuclear waste management relative to other technological and scientific issues; do different segments of the public disagree on its importance; the second question concerned public attitudes toward a nuclear waste disposal facility: how great a risk to health and safety is a nuclear waste disposal facility relative to other industrial facilities; is there disagreement on its riskiness among various public groups; the third question pertained to the aspects of risks that affect overall risk perception: what are the qualitative aspects of a nuclear waste disposal facility that contribute to overall perceptions of risk; do different segments of the population associate different risk characteristics with hazardous facilities. The questions follow from one another: is the issue important; given the importance of the issue, is the facility designed to deal with it considered risky; given the riskiness of the facility, why is it considered risky. Also addressed in this report, and a main focus of its findings, were the patterns of differences among respondent groups on each of these questions

    Risk perception is one of important subjects in management psychology and cognitive psychology. It is of great value in the theory and practice to investigate the societal hazards that the public cares a lot especially in Socio-economic transition period. A survey including 30 hazards and 6 risk attributes was designed and distributed to about 2, 485 residents of 8 districts, Beijing. The major findings are listed as following: Firstly, a scale of societal risk perception was designed and 2 factors were identified (Dread Risk & Unknown Risk). Secondly, structural equation model was used to analyze the influence factors and mechanism of societal risk perception. Risk preference, government support and social justice could influence societal risk perception directly. Government support fully moderated the relationship between government trust and societal risk perception. Societal risk perception influenced life satisfaction, public policy preferences and social development belief.

    Transportation of hazardous materials, and particularly radioactive wastes, on public highways has become an important risk management issue. The unfavorability of public attitudes regarding hazardous and nuclear waste signals the potential for strong public opposition to programs for transporting these materials. This paper presents the results of a survey conducted to assess public reactions to a long-term nuclear waste transport program planned to follow a route through a portion of rural Oregon. The survey assessed a number of key risk perception issues, including perceived health and safety risks of nuclear waste transport, relative risks of transport vs. storage at an existing site, trust in state officials, and satisfaction with life in communities along the transport route. The survey identified a number of attitudes and concerns that need to be understood and considered by those in charge of designing and implementing the waste-transportation program. 22 refs., 1 fig., 5 tabs

  17. The role of risk perception for risk management

    1998-01-01

    Are risks social constructions of different societal actors that can be checked at best against standards of consistency, cohesion and internal conventions of deduction, but cannot claim any validity outside of the actor's logical framework? Or are technical estimates of risk representations of real hazards that can and will affect people as predicted by the statistical values, regardless of the beliefs or convictions of those who conduct the assessments? Which of the two sides one takes determines the legitimate function of risk perception for management purposes. The paper argues that both extremes, the constructivist and the realist perspective, miss the point, as risks are always mental representations of threats that are capable of claiming real losses. Over the last two decades, risk analysts have dealt with both sides of risk in an additive fashion. In times in which risk management has been under serious pressure to demonstrate effectiveness and cost-efficiency, the parallel approach of pleasing the technical elite and the public alike has lost legitimacy. In order to integrate risk assessment and perception, the paper analyses the strengths and weaknesses of each approach to risk analysis and highlights the potential contributions that the technical sciences and the social sciences can offer to risk management. Technical assessments provide the best estimate for judging the average probability of an adverse effect linked to an object or activity. First, public perception should govern the selection of criteria on which acceptability or tolerability are to be judged. Second, public input is needed to determine the trade-offs between criteria. Third, public preferences are needed to design resilient strategies for coping with remaining uncertainties. A public participation model is introduced that promises an integration of analytic knowledge and deliberative process involving those who will be affected by the respective risk

    The social and economic burden of diabetes is large and growing. Diabetes is a significant public health issue in the Appalachian region; women constitute approximately 50% of those diagnosed with diabetes. This cross-sectional study examined the relationship among sociodemographic, anthropometric, lifestyle, and psychosocial factors (cognitive and affective representations) and perceived risk of diabetes in non-diabetic, non-elderly (21-50 years) Appalachian women residing in West Virginia (N = 202). Participants were recruited through social media, flyers, and a newsletter from the West Virginia University Extension. The final survey was conducted from March 2015 to June 2015. Bivariate analyses were used to examine unadjusted relations among sociodemographic, anthropometric, lifestyle, and psychosocial factors and comparative perceived risk of diabetes. In a multivariable logistic regression model, we found that younger age, higher body mass index, non-White race, greater diabetes knowledge, personal control, and moderate amounts of physical activity were significantly, positively associated with higher diabetes risk perception (p related to diabetes risk perception among Appalachian women. Understanding perceived diabetes-related risk may aid in the development of effective intervention strategies to reduce the burden of diabetes among Appalachian and other populations. These cross-sectional findings need further evaluation in longitudinal studies.

    A project for site selection and construction of a national radioactive waste repository is underway at the Comissao Nacional de Energia Nuclear. Public acceptance is determinant to the deployment of an undertaking of this size. A major concern regarding the use of nuclear energy are the problems related to safe management of the radioactive waste. For effective communication between decision makers and the public, a mutual understanding of views, as well as attitudes towards risk, is needed. The use of opinions polls is necessary in order to achieve it. This work aims to point out the major aspects to be approached by an opinion poll for the study of risk perception on the candidate regions for repository construction. A risk perception research model is presented, to be applied to the case of radioactive waste disposal, along with theoretical support to the organization and implementation of its structure.

    The Superfund Amendments and Reauthorization Act of 1986 (SARA) provided the Environmental Protection Agency (EPA) with additional resources and direction for the identification, evaluation, and remediation of hazardous waste sites in the United States. SARA established more stringent requirements for the Superfund program, both in terms of the pace of the program and the types of remedial alternatives selected. The central requirement is that remedial alternatives be ''protective of public health and the environment'' and ''significantly and permanently'' reduce the toxicity, mobility, or volume of contaminants. The mandate also requires that potential risk be considered in the decision-making process. This document discusses risk management at hazardous waste sites. Topics include selection of sites for placement on the National Priority List, risk assessment and the decision process, risk reduction and remedial alternative selection, and aquifer restoration. 10 refs., 2 figs

    Risks are mental models, which allow people to cope with dangerous phenomena (Renn, 2008; Jasanoff, 1998). The term "risk" refers to the likelihood of an adverse effect resulting from an event. The aim of the present study is to identify the psychological factors that are most predictive of risk perception in relation with age, gender, educational level and socio-economical status. Earthquake hazard was considered, because it is an emerging danger for Bucharest. 80% of the laypeople sample are waiting for this event to happen in the next three years. By integrating all the research data, it was attempted to build a risk profile of the investigated population, which could be used by institutions responsible for earthquake risk mitigation situations in Bucharest. This research appealed to the social learning Rotter (1966), auto-effectiveness Bandura (1977; 1983), and anxiety and stress theories. We used psychological variables that measured stress, personal effectiveness and the belief in personal control. The multi-modal risk perception questionnaire was structured on a 49 items sequence. The sample was composed of 1.376 participants recruited on a voluntary basis. The characteristics of risk (like probability and magnitude, time scales) are perceived differently according to psychological factors that play a role also in biases in people's ability to draw inferences from probabilistic information (like cognitive dissonance). Since the 1970's, it has been argued that those who perceive life's events as being beyond their locus of control (external locus of control) are significantly more anxious and less adapted. In this research, strongest associations and significant differences were obtained between sex, age and income categories with Stress vulnerability factor and the External Locus of Control factor. The profile of the low risk perceiver is that of a young, more educated, male individual with a higher self- efficacy level and an internal locus of control.

    Problems of radioactive waste management, both real and apparent, have provided a serious constraint in the development of nuclear power. Several studies have been conducted in an attempt to evaluate the actual (quantifiable) risks of radioactive waste management and place them in a reasonable perspective. These studies are reviewed and discussed. Generally, the studies indicate the risks to be of a level of seriousness which might normally be considered acceptable in current society. However, it is apparent that this acceptability has not been attained and public apprehension prevails. To understand the reasons for this apprehension requires an assessment of those factors of ''perceived'' risks which play a major role in determining public attitudes toward radioactive waste management programs and nuclear power, in general. Such factors might include the spector of legacies of harm to future generations, genetic effects, nuclear garbage dumps, proliferation of plutonium inventories, nuclear terrorism, etc. A major problem in development of acceptable waste management policies and programs requires not only the recognition of the importance of perceived risk factors but development of a methodology for their incorporation in planning and conduct of such activities. Some approaches to the development of this methodology are discussed

Revelation of individual risk perception is essential for local acceptance...... and cooperation. We do this by a comparative study with Bangladesh shrimp farmers and Danish mussel farmers. Since these people live on the edge of subsistence, already small changes in the climate will affect them significantly. Farmers in both developed and developing economies are concerned about global...... climate change but there are significant differences in farmers’ perceptions of the causes of global climate change in developed and developing countries....

    This article reviews central findings and current developments of psychological and sociological research on the perception of health risks. Risk perception is influenced by numerous psychological, social, political, and cultural factors. These factors can be categorized into (a) risk characteristics, (b) characteristics of the risk perceiving person and his/her situation, and (c) characteristics of risk communication. Thus, besides individual cognitive and affective processing of risk information, social processes of risk amplification (e.g., media effects) are also involved in the construction of individual risk perceptions. We discuss the recommendations for health risk communication that follow from these findings with regard to different communication goals.

  6. Quantifying risks in nuclear waste isolation

    1982-01-01

    A top-level application of an RSS risk assessment procedure is selected as a unifying framework within which the long-time (about 1000 years) performance of a waste repository may be considered. Two major themes are developed: First, the fractional contribution of the engineered features to the ''system'' risk is determined. This contribution effectively segregates those features over which conservative design and quality control may be used to control risk. Second, the development of event tree logic to support such analysis is shown to represent a meaningful, systematic means of factoring-in the total system dynamics; in particular, the generality provided by such an approach lends itself well to consideration of a broad spectrum of accident sequences which includes varying responses of the waste repository system to time-dependent ''accident'' initiators and system failure synergism. Modification to traditional logic development methods to span the longtime system performance are described in some detail, and the attendant data requirements are developed

    2015-01-01

    Uncertainty provides opportunities for differences in perception, and radiation risks at low level of exposures involved in few computed tomography scans fall in this category. While there is good agreement among national and international organisations on risk probability of cancer, risk perception has barely been dealt with by these organisations. Risk perception is commonly defined as the subjective judgment that people make about the characteristics and severity of a risk. Severity and latency are important factors in perception. There is a need to connect all these. Leaving risk perception purely as a subjective judgement provides opportunities for people to amplifying risk. The author postulates a risk perception index as severity divided by latency that becomes determining factor for risk perception. It is hoped that this index will bring rationality in risk perception. (authors)

  8. The Psychology of Hazard Risk Perception

    Thompson, K. F.

    2012-12-01

    A critical step in preparing for natural hazards is understanding the risk: what is the hazard, its likelihood and range of impacts, and what are the vulnerabilities of the community? Any hazard forecast naturally includes a degree of uncertainty, and often these uncertainties are expressed in terms of probabilities. There is often a strong understanding of probability among the physical scientists and emergency managers who create hazard forecasts and issue watches, warnings, and evacuation orders, and often such experts expect similar levels of risk fluency among the general public—indeed, the Working Group on California Earthquake Probabilities (WGCEP) states in the introduction to its earthquake rupture forecast maps that "In daily living, people are used to making decisions based on probabilities—from the flip of a coin (50% probability of heads) to weather forecasts (such as a 30% chance of rain) to the annual chance of being killed by lightning (about 0.0003%)." [1] However, cognitive psychologists have shown in numerous studies [see, e.g., 2-5] that the WGCEP's expectation of probability literacy is inaccurate. People neglect, distort, misjudge, or misuse probability information, even when given strong guidelines about the meaning of numerical or verbally stated probabilities [6]. Even the most ubiquitous of probabilistic information—weather forecasts—are systematically misinterpreted [7]. So while disaster risk analysis and assessment is undoubtedly a critical step in public preparedness and hazard mitigation plans, it is equally important that scientists and practitioners understand the common psychological barriers to accurate probability perception before they attempt to communicate hazard risks to the public. This paper discusses several common, systematic distortions in probability perception and use, including: the influence of personal experience on use of statistical information; temporal discounting and construal level theory; the effect

  9. Risk Perception is not what it seems: the Psychometric Paradigm Revisited

    Sjoeberg, Lennart

    2003-01-01

    Risk perception has become an important topic to policy makers concerned with technology and the environment, and the psychological analysis of this construct has attracted much interest. Psychological research on risk perception has been dominated by the psychometric paradigm which has been fruitful in bringing up important issues in research. Yet, most of the conclusions reached in the paradigm are not sufficiently well based on empirical data and appropriate analyses. Results are presented here which show the prevalence of risk for energy attitudes, the importance of Tampering with Nature as a new risk dimension accounting for much of the perceived risk of nuclear waste, widely different levels but similar correlational structures of risk perception data for experts and the public, moderately strong correlations between perceived risk and trust (especially specific trust rather than general trust), and demand for risk mitigation being related most strongly to seriousness of consequences of a hazard, not the risk of an accident or the riskiness of the activity. Risk perception is related to conceptions of knowledge which stress the limits of science and different, New Age type, ways of knowing. Finally, interest emerged as an important predictor of demand for risk mitigation. A conceptualization of the risk perceiver, based on these results, is briefly discussed

    Understanding public perceptions of climate change risks is a prerequisite for effective climate communication and adaptation. Many studies of climate risk perceptions have either analyzed a general operationalization of climate change risk or employed a case-study approach of specific adaptive processes. This study takes a different approach, examining attitudes toward 17 specific, climate-related coastal risks and cognitive, affective, and risk-specific predictors of risk perception. A survey of 558 undergraduates revealed that risks to the physical environment were a greater concern than economic or biological risks. Perceptions of greater physical environment risks were significantly associated with having more pro-environmental attitudes, being female, and being more Democratic-leaning. Perceptions of greater economic risks were significantly associated with having more negative environmental attitudes, being female, and being more Republican-leaning. Perceptions of greater biological risks were significantly associated with more positive environmental attitudes. The findings suggest that focusing on physical environment risks maybe more salient to this audience than communications about general climate change adaptation. The results demonstrate that climate change beliefs and risk perceptions are multifactorial and complex and are shaped by individuals' attitudes and basic beliefs. Climate risk communications need to apply this knowledge to better target cognitive and affective processes of specific audiences, rather than providing simple characterizations of risks.

    The current study investigated how adolescents perceive their own health risks and compare their own likelihood of health risks with that of others of the same age. Moreover, the study identified the differences in health risk perceptions between males and females. A total of 625 adolescents (314 males and 311 females) from the Nowon district, geographically located in northern Seoul, voluntarily participated. In order to measure health risk perceptions a Korean version of self-other risk judgments profile was used. The findings indicated that study participants, regardless of gender and age, tend to underestimate their vulnerability to majority of health risk events. Furthermore, there were significant gender and age differences in health risk perception and perception bias in all health risk domains. The present study suggests that further research is needed to identify realistic and unrealistic perception mechanism for a large number of people from different demographic and socioeconomic backgrounds.

  12. Rationality and irrationality in estimating the risks of nuclear waste disposal

    International Nuclear Information System (INIS)

    Freudenburg, W.R.

    1987-01-01

    In addition to their intrinsic or ''academic'' interest, public perceptions of risks have begun to receive increased scientific attention for at least three reasons that are directly relevant to waste disposal. The first and most commonly recognized reason is that, if people perceive a problem to be real, it will be real in its consequences. This means that unless public perceptions are taken explicitly into account, decisionmaking will be based on inaccurate information, and the impacts of developments will not be properly understood, predicted, or mitigated. The second reason is that, now that perceptions are beginning to be the focus of increased scientific inquiry, the nature of public perceptions is beginning to be better understood. It is becoming clear that it is not accurate to characterize public perceptions and being simply unpredictable or ''irrational,'' and studies are making considerable progress in documenting the factors that tend to influence public perceptions of facilities such as nuclear waste repositories. Third, increasing evidence indicates that the real-versus-perceived distinction is not as clear as was once assumed, and for two reasons. One reason is that, while expert judgments are often taken as representing ''real'' risks for decisionmaking purposes, it is impossible to know the ''real'' risks of technologies for which little or no actual operating experience has accumulated, and expert judgments often prove under closer scrutiny to express the scientists' values as well as science's facts. The other reason is that the broader public's perceptions now appear to reflect more wisdom than was at first apparent

    Santorini, Greece is a major explosive volcano. The Santorini volcanic complex is composed of two active volcanoes—Nea Kameni and Mt. Columbo. Holocene eruptions have generated a variety of processes and deposits and eruption mechanisms pose significant hazards of various types. It has been recognized that, for major European volcanoes, few studies have focused on the social aspects of volcanic activity and little work has been conducted on public perceptions of hazard, risk and vulnerability. Such assessments are an important element of establishing public education programmes and developing volcano disaster management plans. We investigate perceptions of volcanic hazards on Santorini. We find that most residents know that Nea Kameni is active, but only 60% know that Mt. Columbo is active. Forty percent of residents fear that negative impacts on tourism will have the greatest effect on their community. In the event of an eruption, 43% of residents would try to evacuate the island by plane/ferry. Residents aged >50 have retained a memory of the effects of the last eruption at the island, whereas younger residents have no such knowledge. We find that dignitaries and municipal officers (those responsible for planning and managing disaster response) are informed about the history, hazards and effects of the volcanoes. However, there is no "emergency plan" for the island and there is confusion between various departments (Civil Defense, Fire, Police, etc.) about the emergency decision-making process. The resident population of Santorini is at high risk from the hazards associated with a future eruption.

    The author has a critical look at the proposal by Pangea Resources Australia Pty Ltd (PARPL) to establish in Australia a permanent underground disposal site for radioactive waste from around the world. In his opinion, the inevitable risk in the proposal stems from the magnitudes: 250,000 tonnes of enormously dangerous RADwaste in the northern hemisphere 20,000 km from its destined dump in Australia, where it must remain intact for at least 10,000 years. These magnitudes - of tonnage, lethality, distance of transport, and time - entail great inherent risk. He also argue that the job of the Australian scientists is to apply due diligence to PARPL proposal

    Adolescence is a period of life in which peer relationships become increasingly important. Adolescents have a greater likelihood of taking risks when they are with peers rather than alone. In this study, we investigated the development of social influence on risk perception from late childhood through adulthood. Five hundred and sixty-three participants rated the riskiness of everyday situations and were then informed about the ratings of a social-influence group (teenagers or adults) before rating each situation again. All age groups showed a significant social-influence effect, changing their risk ratings in the direction of the provided ratings; this social-influence effect decreased with age. Most age groups adjusted their ratings more to conform to the ratings of the adult social-influence group than to the ratings of the teenager social-influence group. Only young adolescents were more strongly influenced by the teenager social-influence group than they were by the adult social-influence group, which suggests that to early adolescents, the opinions of other teenagers about risk matter more than the opinions of adults. © The Author(s) 2015.

  20. Radiological social risk perception: something more than experts/ public discrepancies

    One of the most important concerns of the postindustrial societies lies on the specification and quantification of risk, the Risk Assesment. However, the efforts and resources devoted to such goal have not avoided a growing worry about both the environmental conditions and the situations that potentially threaten it, generating an intense social debate about risks. In this framework, discrepancies between experts and public evaluations risks leaded to the study of social Risk perception. Several theoretical scopes have tried to characterize the phenomenon. A worthy conclusion of the empirical studies carried out on this issue is that all of them, experts and public, are influence by some factors which, in turns, affect their risk perception,. Specially striking is the fact that perception of risk among experts is also modulated by qualitative, personal and social factors. Social Risk Perception, through the process of Communication and Social Participation, has been configurated as a critical tool for both risk prevention and management

    In this article, we present the results of a study investigating the influence of vulnerability to climate change as a function of physical vulnerability, sensitivity, and adaptive capacity on climate change risk perception. In 2008/2009, we surveyed Nevada ranchers and farmers to assess their climate change-related beliefs, and risk perceptions, political orientations, and socioeconomic characteristics. Ranchers' and farmers' sensitivity to climate change was measured through estimating the proportion of their household income originating from highly scarce water-dependent agriculture to the total income. Adaptive capacity was measured as a combination of the Social Status Index and the Poverty Index. Utilizing water availability and use, and population distribution GIS databases; we assessed water resource vulnerability in Nevada by zip code as an indicator of physical vulnerability to climate change. We performed correlation tests and multiple regression analyses to examine the impact of vulnerability and its three distinct components on risk perception. We find that vulnerability is not a significant determinant of risk perception. Physical vulnerability alone also does not impact risk perception. Both sensitivity and adaptive capacity increase risk perception. While age is not a significant determinant of it, gender plays an important role in shaping risk perception. Yet, general beliefs such as political orientations and climate change-specific beliefs such as believing in the anthropogenic causes of climate change and connecting the locally observed impacts (in this case drought) to climate change are the most prominent determinants of risk perception. © 2012 Society for Risk Analysis.

    The objectives of risk assessment studies for radioactive waste disposal are: to specify the features that prevent the escape of radionuclides from a deep disposal vault, to estimate how effective these features are likely to be, and to determine the potential consequences of the expected situation and conceivable but unlikely situations. The major features to be analysed include the insoluble nature of the waste form itself, the resistance of its container to corrosion or mechanical damage, the effectiveness of the massive rock barrier and the hold-up and dilution of radionuclides in the surface environment. Computer modelling is used in a technique called ''pathway analysis'' to bring together the experimental data, field data and understanding of the relevant phenomena into an assessment of the resultant effect on man and the environment.

    Full text: Since 1997, IRSN conducts a yearly survey designed to understand how the French population perceives risk: the IRSN barometer. In this survey, 30 risks are investigated from three different angles: a) Seriousness of the risk; b) Trust in the authorities; c) Credibility of information given about these risks. The 30 risks include situations widely covered by the media (traffic accidents, smoking, alcohol, etc.), as well as situations of which the public can be unaware (such as radon in homes) and situations perceived as low risk (X-rays, noise, etc.). The list includes nuclear power plants, nuclear waste storage, Chernobyl pollution impacts, chemical industries, chemical waste, transportation of hazardous chemicals, etc. Statistical analysis of the answers highlighted five groups of risks in relation with a common rationale of perception by the French people. This will be presented as the first part of the paper. The conclusion will show that the risk perceptions of the French population are not at all versatile. Their perception logic is based on the perceived seriousness of the risk, on their 'trust in the protective measures taken by the French authorities' and on the perceived credibility of information. Risk perception varies greatly with age, gender, culture and level of education. We know this with the IRSN Barometer and others opinion pools. However, few surveys are carried out among experts in risk. Do they have a different perception of risk from the general public? It's the subject of a study entitled PERPLEX (Perception of Risk by the Public and Experts) who was realized in October 2004. This will be presented in the second part of the paper. The same question can be asked for the population who live near a nuclear power plant or other nuclear facility. So, in November 2007, 318 residents in the vicinity of twenty nuclear facility have answered at the IRSN's annual barometer questionnaire. The results of these three surveys will be presented

    Public risk perceptions of mass disasters carry considerable influences, both psychologically and economically, despite their oft-times imprecise nature. Prior research has identified the presence of an optimistic bias that affects risk perception, but there is a dearth of literature examining how these perceptions differ among cultures-particularly with regard to mass disasters. The present study explores differences among Japanese, Argentinean, and North American mental health workers in their rates of the optimistic bias in risk perceptions as contrasted between natural disasters and terrorist events. The results indicate a significant difference among cultures in levels of perceived risk that do not correspond to actual exposure rates. Japanese groups had the highest risk perceptions for both types of hazards and North Americans and Argentineans had the lowest risk perceptions for terrorism. Additionally, participants across all cultures rated risk to self as lower than risk to others (optimistic bias) across all disaster types. These findings suggest that cultural factors may have a greater influence on risk perception than social exposure, and that the belief that one is more immune to disasters compared to others may be a cross-cultural phenomenon. © 2010 Society for Risk Analysis.

  7. Risk perception as a factor in policy and decision making

    2004-01-01

    Risk perception is often believed to be an important factor in policy decision making, when it comes to the management of hazardous technology. Research on risk perception by the public since the 1970's has purportedly shown that such perception is emotional and based on ignorance. Experts, on the other hand, have been claimed to be objective and correct in their risk assessments. The present paper reviews a large body of research which has led to a quite different conclusions, viz. that emotions play only a marginal role in risk perception, which is mainly driven by ideological concerns and attitudes. The methodological shortcomings of the prevailing view of risk perception as emotional and simply misinformed are described. (author)

    This study addresses the issues of perception of nuclear risks and social-economic impacts while discussing the role awarded to experts regarding these issues, as well as public perception. It first discusses the emergence of the French nuclear sector in the post-war context and with its civil and military components. It discusses the public perception of the associated technological risk, and more particularly the relationship between citizen and nuclear techno-science, notably through governance models. The next part addresses the specific case of nuclear wastes to analyse public perceptions as well as possible disciplinary approaches, and to discuss three theoretical risk approaches: the economic one, the psychological one, and the sociological one. Three empirical studies of the perception of the nuclear risk are then commented: an IRSN comparative study on public opinions and expert opinions, an IRSN survey performed on a sample of teachers, and a CNRS survey performed on a sample of researchers. The comparative study and another survey are then discussed at the light of the decision theory. A mathematical representation of relationships between policy and perception and based on the viability theory is then proposed

    Objectives We aim to present new knowledge about different perspectives of health care professionals’ risk perceptions and clinical decision making. Furthermore, we intend to discuss differences between professional and personal risk perceptions and the impact on decisions in terms of both short...... and long-term outcomes. Background Insight into healthcare professionals’ perception of risk is a cornerstone for understanding their strategies for practising preventive care. The way people perceive risk can be seen as part of a general personality trait influenced by a mixture of individual...... considerations and the specific context. Most research has been focused on understanding of the concepts of risk. However healthcare professionals’ risk perception and personal attitudes also affect their clinical decision-making and risk communication.

    Risk perceptions are only slightly correlated with the expected values of a probability distribution for negative health impacts. Psychometric studies have documented that context variables such as dread or personal control are important predictors for the perceived seriousness of risk. Studies about cultural patterns of risk perceptions emphasize different response set to risk information, depending on cultural priorities such as social justice versus personal freedom. This chapter reports the major psychological research pertaining to the factors that govern individual risk perception and discusses the psychometric effects due to people's risk perception and the experience of severe stress. The relative importance of the psychometric content variables, the signals pertaining to each health risks and symbolic beliefs are explained. (Author)

    In environmental surveys, risk perception may be a source of bias when information on health outcomes is reported using questionnaires. Using the data from a survey carried out in the largest chipboard industrial district in Italy (Viadana, Mantova), we devised a score of health risk perception and described its determinants in an adult population. In 2006, 3697 parents of children were administered a questionnaire that included ratings on 7 environmental issues. Items dimensionality was studied by factor analysis. After testing equidistance across response options by homogeneity analysis, a risk perception score was devised by summing up item ratings. Factor analysis identified one latent factor, which we interpreted as health risk perception, that explained 65.4% of the variance of five items retained after scaling. The scale (range 0-10, mean ± SD 9.3 ± 1.9) had a good internal consistency (Cronbach's alpha 0.87). Most subjects (80.6%) expressed maximum risk perception (score = 10). Italian mothers showed significantly higher risk perception than foreign fathers. Risk perception was higher for parents of young children, and for older parents with a higher education, than for their counterparts. Actual distance to major roads was not associated with the score, while self-reported intense traffic and frequent air refreshing at home predicted higher risk perception. When investigating health effects of environmental hazards using questionnaires, care should be taken to reduce the possibility of awareness bias at the stage of study planning and data analysis. Including appropriate items in study questionnaires can be useful to derive a measure of health risk perception, which can help to identify confounding of association estimates by risk perception.

  12. Rethinking the relationship between flood risk perception and flood management.

    2014-04-15

    Although flood risk perceptions and their concomitant motivations for behaviour have long been recognised as significant features of community resilience in the face of flooding events, there has, for some time now, been a poorly appreciated fissure in the accompanying literature. Specifically, rationalist and constructivist paradigms in the broader domain of risk perception provide different (though not always conflicting) contexts for interpreting evidence and developing theory. This contribution reviews the major constructs that have been applied to understanding flood risk perceptions and contextualises these within broader conceptual developments around risk perception theory and contemporary thinking around flood risk management. We argue that there is a need to re-examine and re-invigorate flood risk perception research, in a manner that is comprehensively underpinned by more constructivist thinking around flood risk management as well as by developments in broader risk perception research. We draw attention to an historical over-emphasis on the cognitive perceptions of those at risk to the detriment of a richer understanding of a wider range of flood risk perceptions such as those of policy-makers or of tax-payers who live outside flood affected areas as well as the linkages between these perspectives and protective measures such as state-supported flood insurance schemes. Conclusions challenge existing understandings of the relationship between risk perception and flood management, particularly where the latter relates to communication strategies and the extent to which those at risk from flooding feel responsible for taking protective actions.

  13. Risk perception in Western Europe 10 years after the Chernobyl accident

    Sjoeberg, L.

    1999-01-01

    What have we learned about risk perception? Let me summarize a few highlights: Perceived risk is at the present highest with regard to acute economic needs, but the environment and nuclear technology are also important. Nuclear technology has a special role in being perceived as very low in 'control', i.e. if you can protect yourself from its hazards. Media do play an important role in risk perception, but it is more subtle than most often believed. Media do affect our beliefs by the information they bring us, but not necessarily by increasing the 'availability of what we already know'. Trust is not the primary factor in risk perception that it often is believed to be - it does play a role at a moderate level of power. It may be that trust is a necessary but not sufficient factor for risk 'acceptance'. In Western Europe, we have noted very large variations among countries both with regard to trust and perceived risk. Inclusion of other societies would probably have meant observation of even greater variation. The RISKPERCOM project serves as a starting point for further work on risk perception and technology. Attitudes and values need to be studied in a broader frame than merely perceived risk, as the project has shown. Future research on such acute topics as nuclear waste is called for; the project has already produced a number of results in that area but space restrictions preclude me from reviewing them here

  15. Radiation risk perception and public information

    We as Health Physicists face what, at many times, appears to be a hopeless task. The task simply stated is informing the public about the risks (or lack thereof) of radiation. Unfortunately, the public has perceived radiation risks to be much greater than they actually are. An example of this problem is shown in a paper by Arthur C. Upton. Three groups of people -- the League of Women Voters, students, and Business and Professional Club members -- were asked to rank 30 sources of risk according to their contribution to the number of deaths in the United States. Not surprisingly, they ranked nuclear power much higher and medical x-rays much lower than the actual values. In addition to the perception problem, we are faced with another hurdle: health physicists as communicators. Members of the Health Physics Society (HPS) found that the communication styles of most health physicists appear to be dissimilar to those of the general public. These authors administered the Myers-Briggs Type Indicator to the HPS Baltimore-Washington Chapter. This test, a standardized test for psychological type developed by Isabel Myers, ask questions that provide a quantitative measure of our natural preferences in four areas. Assume that you as a health physicist have the necessary skills to communicate information about radiation to the public. Health physicists do nothing with these tools. Most people involved in radiation protection do not get involved with public information activies. What I will attempt to do is heighten your interest in such activities. I will share information about public information activities in which I have been involved and give you suggestions for sources of information and materials. 2 refs., 1 tab

  16. The aesthetics of hazardous waste - Distinguishing visual impacts from publicly perceived risk

    International Nuclear Information System (INIS)

    Sheppard, S.

    1986-01-01

    The need to address the aesthetic impacts of hazardous waste projects on the environment and the public stems from two sources: government regulations which specifically require assessment of aesthetic effects; and rapidly increasing public concern for perceived impacts and risks of existing or proposed hazardous waste facilities. How aesthetic issues are handled on hazardous waste projects can potentially have significant implications on the fate of those projects. These implications range from delays in the permitting process to denial of sites or costly legal judgments in damage suits. This paper discusses strategies for evaluating the aesthetic/perceptual aspects of hazardous waste. In particular, it focuses upon ways to distinguish visual concerns from other influences on public perceptions such as perceived health and safety risks

    Technological stigmas can be a source of confusion and misunderstandings of the effect on public health and safety of technological activities. The result can be a gross waste of national resources to fix the 'stigma' rather than the real problem. Fueling technological stigmas has become a visible activity, especially among non-technical professionals. Further, it is not clear that these same critics are accountable for their influence on policy and practices that may adversely affect people's lives and financial resources. Their bad news of alleged high risk and incompetent technologists is more appealing to the press than the more technical and apparently boring news of finding engineering solutions to real problems. The issue of technological stigma is especially visible in relation to the environmental and safety effects of the nuclear and chemical industries. These industries are in an extremely defensive position because the stigmatizes put much more emphasis on their risks than on their benefits to society. There is the genuine threat of the denial of important technologies in the nuclear and chemical fields and a resulting loss of lives and resources. The actions required to better tell the whole cost-risk-benefit story of specific technologies have to come from all of the groups involved. The critics and stigmatizers need to be more accountable for their assertions, the technologists need to involve the public more in their consideration of technological solutions to environmental and safety issues, and the press needs to present all of the facts rather than just the sensational or 'outrage' part of the story.

    Waterborne disease is estimated to cause about 10% of all diseases worldwide. However, related risk perceptions are not well understood, particularly in the developing world where waterborne disease is an enormous problem. We focus on understanding risk perceptions related to these issues in a region within northern Mexico. Our findings show how waterborne disease problems and solutions are understood in eight small communities along a highly contaminated river system. We found major differences in risk perceptions between health professionals, government officials, and lay citizens. Health professionals believed that a high level of human-waste-related risk existed within the region. Few officials and lay citizens shared this belief. In addition, few officials and lay citizens were aware of poor wastewater-management-related disease outbreaks and water contamination. Finally, aside from health professionals, a few interviewees understood the importance of basic hygiene and water treatment measures that could help to prevent disease. Our results add to the literature on environmentally-related risk perceptions in the developing world. We discuss recommendations for improving future human-wastewater-related risk communication within the region. © 2011 Society for Risk Analysis.

    The extent to which people are willing to take on risk, i.e. their risk preferences as well as subjective risk perception plays a major role in explaining their behavior. This is of particular relevance in agricultural production, which is inherently risky. The data presented here was collected amongst a total of 64 German farmers in 2015. It includes results of three different risk preference elicitation methods (multiple price list, business statements in four relevant domains and general self-assessment) as well as risk perception. Additionally, farm business characteristics (e.g. size, farm-level workforce, succession) and personal farmer characteristics (e.g. age, gender, risk literacy) are included.

  3. A discussion of the limitations of the psychometric and cultural theory approaches to risk perception

    International Nuclear Information System (INIS)

    Sjoeberg, L.

    1996-01-01

    Risk perception has traditionally been conceived as a cognitive phenomenon, basically a question of information processing. The very term perception suggests that information processing is involved and of crucial importance. Kahneman and Tversky suggested that the use of 'heuristics' in the intuitive estimation of probabilities accounts for biased probability perception, hence claiming to explain risk perception as well. The psychometric approach of Slovic et al, a further step in in the cognitive tradition, conceives of perceived risk as a function of general properties of a hazard. However, the psychometric approach is shown here to explain only about 20% of the variance of perceived risk, even less of risk acceptability. Its claim to explanatory power is based on a statistical illusion: mean values were investigated and accounted for, across hazards. A currently popular alternative to the psychometric tradition, Cultural Theory, is even less successful and explains only about 5% of the variance of perceived risk. The claims of this approach were also based on a statistical illusion: 'significant' results were reported and interpreted as being of substantial importance. The present paper presents a new approach: attitude to the risk generating technology, general sensitivity to risks and specific risk explained well over 60% of the variance of perceived risk of nuclear waste, in a study of extensive data from a representative sample of the Swedish population. The attitude component functioning as an explanatory factor of perceived risk, rather than as a consequence of perceived risk, suggests strongly that perceived risk is something other than cognition. Implications for risk communication are discussed. (author)

    In order to gain a better understanding and acceptance of the task of implementing high level radioactive waste disposal, a study on new communication system about social risk information has been initiated by noticing the rapid expansion of Internet in the society. First, text mining method was introduced to identify the core public interest, examining public comments on the technical report of high level radioactive waste disposal. Then we designed the dialog-mode contents based on the theory of norm activation by Schwartz. Finally, the discussion board was mounted on the web site. By constructing such web communication system which includes knowledge base contents, introspective contents, and interactive discussion board, we conducted the experiment for verifying the principles such as that the basic technical knowledge and trust, and social ethics are indispensable in this process to close the perception gap between nuclear specialists and the general public. The participants of the experiment increased their interest in the topics with which they were not familiar and actively posted their opinions on the BBS. The dialog-mode contents were significantly more effective than the knowledge-based contents in promoting introspection that brought people into a greater awareness of problems such as social dilemma.

    This article examines why, as suggested by the Three Mile Island Nuclear Station (TMI) event, the public is more inclined to evacuate in response to a radiation release than to a natural hazard. During the TMI incident, for example, did authorities present confusing or conflicting information or did the public have an exaggerated perception of radiation risk. Behavioral intention studies are combined with risk perception analyses to ascertain (1) the extent to which intentions to evacuate can be generalized from one sample to another and from one hazard to another, (2) the degree to which behavioral intentions are related to specific dimensions of risk perception, and (3) how public perceptions of risk compare with estimates of risk produced by reactor accident consequence analyses

    Full Text Available Health-care workers are at risk of exposure to occupational infections with subsequent risk of contracting diseases, disability, and even death. A systematic collection of occupational disease data is useful for monitoring current trends in work situations and disease exposures; however, these data are usually limited due to under-reporting. The objective of this study was to review literature related to knowledge, risk perceptions, and practices regarding occupational exposures to infectious diseases in Malaysian health-care settings, in particular regarding blood-borne infections, universal precautions, use of personal protective equipment, and clinical waste management. The data are useful for determining improvements in knowledge and risk perceptions among health-care workers with developments of health policies and essential interventions for prevention and control of occupational diseases.

    Full Text Available Abstract Background Risk perception is considered a motivating factor for adopting preventive behaviors. This study aimed to verify the demographic characteristics and cancer family history that are predictors of risk perception and to verify if risk perception is a predictor of colonoscopy adherence. Methods Individuals with a family colorectal cancer history as indicated by a proband with cancer were interviewed by telephone. They responded to a questionnaire covering demographic characteristics, colonoscopy history and four questions on risk perception. Tests of multiple linear regression and logistic regression were used to identify associations between dependent and independent variables. Results The 117 participants belonged to 62 families and had a mean age of 45.2 years. The majority of these individuals were female (74.4% and from families who met the Amsterdam Criteria (54.7%. The average risk perception was 47.6%, with a median of 50%. The average population perception of individual risk was 55.4%, with a median of 50%. Variables associated with a higher risk perception were age, gender, religion, school level, income, and death of a family member. The variable predicting colonoscopy was receiving medical information regarding risk (odds ratio OR 8.40. Conclusions We found that family cancer history characteristics (number of relatives with cancer, risk classification are associated with adequate risk perception. Risk perception does not predict colonoscopy in this sample. The only variable that predicted colonoscopy was receiving medical information recommending screening.

  10. Exposure knowledge and risk perception of RF EMF

    Full Text Available The presented study is part of the EU Project LEXNET (Low EMF Exposure Future Networks, which deals among other things with the issue of whether a reduction of the radiofrequency (RF electro-magnetic fields (EMF exposure will result in more acceptance of wireless communication networks in the public sphere.We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception. Therefore we evaluated respondents’ risk perceptions of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF risk perception is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features - except distance - do influence people’s general RF EMF risk perceptions. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF risk perception of various sources. The results show a tendency that better exposure knowledge leads to higher risk perception, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and risk perception. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries.

    2016-09-01

    Building on the theoretical arguments of the impersonal-impact and differential-impact hypotheses, this study has a twofold purpose: first, to demonstrate how fear-arousing media messages about risk are associated with personal-level risk perception, as well as, and perhaps more so than, societal-level risk perception; and second, to examine how the resulting risk perceptions can mediate intention to talk about the risk with family and friends. A news message evaluation study was conducted among the general public in South Korea concerning two major risks, carcinogens and bovine spongiform encephalopathy (BSE). Two sets of structural equation models reveal three main findings: (a) Fear-arousing news messages are positively related to personal-level risk perception, as well as to societal-level risk perception; (b) fear-arousing news messages result in intention to talk about the risk directly and indirectly through risk perception; and (c) personal-level risk perception appears more strongly related to intention to talk than does societal-level risk perception, although such relationships may vary across risk topics.

  12. Informal Risk Perceptions and Formal Theory

    2001-01-01

    Economists have argued persuasively that our goals are wider than just risk minimization, and that they include a prudent weighing of costs and benefits. This economic line of thought recognizes that our policy goals are complex. As we widen the range of goals we are willing to entertain, though, we need to check that the methods we customarily employ are appropriate for the tasks to which we customarily apply them. This paper examines some economic methods of risk assessment, in light of the question of what our policy goals are and should be. Once the question of goals is open, more complexities than just cost intrude: what the public wants and why begs to be addressed. This leads us to the controversial issue of public risk perceptions. We have now examined a number of procedures that experts use to make public policy decisions. Behind all these issues is always the question of social welfare: what actions can we take, what policies should we embrace, to make the world a better place? In many cases, the public and the experts disagree about what the right choice is. In the first section, we saw a possible defense of the experts based on democratic theory: the people's participation, and even their will, can be legitimately set aside in the pursuit of their true interests. If this defense is to work, a great deal of weight rests on the question of the people's interests and the competence and integrity of the experts' pursuit of it. But at the same time, social preferences are ill-defined, and so are not good candidates for rational actor theory. Both the prescriptive legitimacy claim and the very workings of formal theory we have seen to depend on informal, qualitative, political judgments. Unfortunately, we have also seen a steady pattern of expert reliance on technical procedures even when they were manifestly unsuited to the task. The experts seem so intent on excluding informal thought that they would prefer even a bad quantitative process to a qualitative

    One factor women consider when deciding whether to pursue amniocentesis is the risk of miscarriage. People use mechanisms like anchoring, or the prior belief regarding the magnitude of risk, as a frame of reference for new information. This study aimed to determine a woman's perception of miscarriage risk associated with amniocentesis before and after genetic counseling and to determine what factors anchor a woman's perception of miscarriage risk. One hundred thirteen women being seen for prenatal genetic counseling and possible amniocentesis at six Houston clinics participated in the two-part anonymous survey. While most women (56.7 %) perceived the risk as low or average pre-counseling and indicated the numeric risk of amniocentesis as risk as risk perception did not change after the genetic counseling session (60 %). Those who changed their feeling about the risk after counseling showed a decreased perception of the risk (p perception of the risk (p = 0.017) whereas those who declined amniocentesis were more likely to view the risk as high (p = 0.004). The only two anchoring factors that had an effect were having a friend or relative with a personal or family history of a genetic disorder (p = 0.001) and having a child already (p = 0.038); both were associated with a lower risk perception. The lack of significant factors may reflect the uniqueness of each patient's risk assessment framework and reinforces the importance of genetic counseling to elucidate individual concerns, particularly as non-invasive prenatal testing becomes more widely available and further complicates the prenatal testing landscape.

    Risk communication and vaccines is complex and the nature of risk perception is changing, with perceptions converging, evolving and having impacts well beyond specific geographic localities and points in time, especially when amplified through the Internet and other modes of global communication. This article examines the globalization of risk perceptions and their impacts, including the example of measles and the globalization of measles, mumps and rubella (MMR) vaccine risk perceptions, and calls for a new, more holistic model of risk assessment, risk communication and risk mitigation, embedded in an ongoing process of risk management for vaccines and immunization programmes. It envisions risk communication as an ongoing process that includes trust-building strategies hand-in-hand with operational and policy strategies needed to mitigate and manage vaccine-related risks, as well as perceptions of risk.

    Scientists and policy makers were slow to recognize the importance of public attitudes and perceptions in shaping the fate of nuclear power. In 1976, Alvin Weinberg observed: 'As I compare the issues we perceived during the infancy of nuclear energy with those that have emerged during its maturity, the public perception and acceptance of nuclear energy appears to be the question that we missed rather badly.... This issue has emerged as the most critical question concerning the future of nuclear energy.' Today, fourteen years later, the problem of public acceptance is even more critical. Either the problem is damn tough or we have not been working hard enough to solve it (I suspect that both of these assertions are true). Public support for nuclear power has declined steadily for a decade and a half, driven by a number of powerful forces and events. In mid-March of 1979, the movie The China Syndrome had its premier, dramatizing the worst-case predictions of the earliest risk assessment studies. Two weeks later, events at Three Mile Island made the movie appear prophetic. Succeeding years have brought us Chernobyl and other major technological disasters, most notably Bhopal and the Challenger accident. The public has drawn a common message from these accidents - that nuclear (and other) complex technology is unsafe, that expertise is inadequate, and that government and industry cannot be trusted to manage nuclear power safely. These dramatic accidents and the distrust they have spawned have been reinforced by numerous chronic problems involving radiation, such as the discovery of significant radon concentrations in many homes, the continuing battles over the siting of facilities to store or dispose of nuclear wastes, and the disclosures of serious environmental contamination emanating from nuclear weapons facilities (at Hanford, Fernald, Rocky Flats and Savannah River)

One of the aims of this RAS program is to inform the public and advise the authorities on methods for transmutation/conditioning of nuclear waste, and on techniques which are being developed. Such new procedures for the treatment of waste should of course not lead to significant risks for the present population. Small risks might be accepted, but these should sufficiently be compensated for by favours to future generations.

    Nanotechnology involves the fabrication, manipulation, and control of materials at the atomic level and may also bring novel uncertainties and risks. Potential parallels with other controversial technologies mean there is a need to develop a comprehensive understanding of processes of public perception of nanotechnology uncertainties, risks, and benefits, alongside related communication issues. Study of perceptions, at so early a stage in the development trajectory of a technology, is probably unique in the risk perception and communication field. As such it also brings new methodological and conceptual challenges. These include: dealing with the inherent diversity of the nanotechnology field itself; the unfamiliar and intangible nature of the concept, with few analogies to anchor mental models or risk perceptions; and the ethical and value questions underlying many nanotechnology debates. Utilizing the lens of social amplification of risk, and drawing upon the various contributions to this special issue of Risk Analysis on Nanotechnology Risk Perceptions and Communication, nanotechnology may at present be an attenuated hazard. The generic idea of "upstream public engagement" for emerging technologies such as nanotechnology is also discussed, alongside its importance for future work with emerging technologies in the risk communication field. © 2011 Society for Risk Analysis.

    Lay judgments of environmental risks are central to both immediate decisions (e.g., taking shelter from a storm) and long-term ones (e.g., building in locations subject to storm surges). Using methods from quantitative psychology, we provide a general approach to studying lay perceptions of environmental risks. As a first application of these methods, we investigate a setting where lay decisions have not taken full advantage of advances in natural science understanding: tornado forecasts in the US and Canada. Because official forecasts are imperfect, members of the public must often evaluate the risks on their own, by checking environmental cues (such as cloud formations) before deciding whether to take protective action. We study lay perceptions of cloud formations, demonstrating an approach that could be applied to other environmental judgments. We use signal detection theory to analyse how well people can distinguish tornadic from non-tornadic clouds, and multidimensional scaling to determine how people make these judgments. We find that participants (N = 400 recruited from Amazon Mechanical Turk) have heuristics that generally serve them well, helping participants to separate tornadic from non-tornadic clouds, but which also lead them to misjudge the tornado risk of certain cloud types. The signal detection task revealed confusion regarding shelf clouds, mammatus clouds, and clouds with upper- and mid-level tornadic features, which the multidimensional scaling task suggested was the result of participants focusing on the darkness of the weather scene and the ease of discerning its features. We recommend procedures for training (e.g., for storm spotters) and communications (e.g., tornado warnings) that will reduce systematic misclassifications of tornadicity arising from observers’ reliance on otherwise useful heuristics.

    Climate change is an increasingly salient issue for societies and policy-makers worldwide. It now raises fundamental interdisciplinary issues of risk and uncertainty analysis and communication. The growing scientific consensus over the anthropogenic causes of climate change appears to sit at odds with the increasing use of risk discourses in policy: for example, to aid in climate adaptation decision making. All of this points to a need for a fundamental revision of our conceptualization of what it is to do climate risk communication. This Special Collection comprises seven papers stimulated by a workshop on "Climate Risk Perceptions and Communication" held at Cumberland Lodge Windsor in 2010. Topics addressed include climate uncertainties, images and the media, communication and public engagement, uncertainty transfer in climate communication, the role of emotions, localization of hazard impacts, and longitudinal analyses of climate perceptions. Climate change risk perceptions and communication work is critical for future climate policy and decisions. © 2012 Society for Risk Analysis.

  12. The Affective Bases of Risk Perception: Negative Feelings and Stress Mediate the Relationship between Mental Imagery and Risk Perception.

    Sobkow, Agata; Traczyk, Jakub; Zaleskiewicz, Tomasz

    2016-01-01

    Recent research has documented that affect plays a crucial role in risk perception. When no information about numerical risk estimates is available (e.g., probability of loss or magnitude of consequences), people may rely on positive and negative affect toward perceived risk. However, determinants of affective reactions to risks are poorly understood. In a series of three experiments, we addressed the question of whether and to what degree mental imagery eliciting negative affect and stress influences risk perception. In each experiment, participants were instructed to visualize consequences of risk taking and to rate riskiness. In Experiment 1, participants who imagined negative risk consequences reported more negative affect and perceived risk as higher compared to the control condition. In Experiment 2, we found that this effect was driven by affect elicited by mental imagery rather than its vividness and intensity. In this study, imagining positive risk consequences led to lower perceived risk than visualizing negative risk consequences. Finally, we tested the hypothesis that negative affect related to higher perceived risk was caused by negative feelings of stress. In Experiment 3, we introduced risk-irrelevant stress to show that participants in the stress condition rated perceived risk as higher in comparison to the control condition. This experiment showed that higher ratings of perceived risk were influenced by psychological stress. Taken together, our results demonstrate that affect-laden mental imagery dramatically changes risk perception through negative affect (i.e., psychological stress).

    The concept of risk cannot be limited to simply knowing the probability of occurrence and the seriousness of the damages caused. It's a matter of social construction and numerous elements contribute towards its perception and acceptability. These elements have been studied for 20 years or so. Some of these elements influence risk perception such as awfulness, unfamiliarity, the number of people exposed to it, other elements influence its acceptance such as individual perceptions, social factors, ethics and equity. Their knowledge allows a better understanding of the evolution of perception and of the risk acceptability in general and transfusion risk in particular.

    Currently, more conflicts appear between the public and government over the establishment of the 4th nuclear power plant in Taiwan. In order to improve risk management by the Society, understanding the risk perception of the public will be essential. A pilot study on the risk perception toward nuclear power operation and other current risks was conducted in summer of 1999. In addition to perception towards nuclear power operation, the survey evaluated several dimensions of health-related risks including smoking, chemical wastes, nuclear wastes, air transportation, AIDS, and food intoxication. The questionnaire was designed to be proceeded under systemic instruction and followed with self-filling. 57 (85.1%) of 67 respondents worked at the Taipei Metropolitan Rapid Transportation, including 62 male subjects (92.5%). 44 (69.8%) respondents favored building the 4th nuclear power plant in Taiwan. The acceptable distance between their houses and the nuclear power plant was 145.13 km in average, as compared with 400 km that of North and South of Taiwan. The mean expenses they are willing to pay to reduce the risk of the NPP is about US $7.73, 0.56% of their average income. However, the levels of risks toward nuclear power operation is significant higher than these for air transportation, smoking, and food intoxication. Government's spending is assumed more effective to reduce the threats from risks of nuclear power operation, rather than professional's or experts' effects. Besides, other related factors include levels of involuntary exposure to NP operation (p<0.001) and number of people potentially in danger (p<0.001). These 2 altitudes are positively correlated with the respondents' perceived risks. Different attitudes toward NP operation within these engineers, and those evaluated by others, are of great interest. Further evaluation will be conducted to compare the mechanism involved.

  16. Prior storm experience moderates water surge perception and risk.

    Directory of Open Access Journals (Sweden)

    Gregory D Webster

    Full Text Available BACKGROUND: How accurately do people perceive extreme water speeds and how does their perception affect perceived risk? Prior research has focused on the characteristics of moving water that can reduce human stability or balance. The current research presents the first experiment on people's perceptions of risk and moving water at different speeds and depths. METHODS: Using a randomized within-person 2 (water depth: 0.45, 0.90 m ×3 (water speed: 0.4, 0.8, 1.2 m/s experiment, we immersed 76 people in moving water and asked them to estimate water speed and the risk they felt. RESULTS: Multilevel modeling showed that people increasingly overestimated water speeds as actual water speeds increased or as water depth increased. Water speed perceptions mediated the direct positive relationship between actual water speeds and perceptions of risk; the faster the moving water, the greater the perceived risk. Participants' prior experience with rip currents and tropical cyclones moderated the strength of the actual-perceived water speed relationship; consequently, mediation was stronger for people who had experienced no rip currents or fewer storms. CONCLUSIONS: These findings provide a clearer understanding of water speed and risk perception, which may help communicate the risks associated with anticipated floods and tropical cyclones.

  17. Advanced maternal age and risk perception: A qualitative study

    Science.gov (United States)

    2012-01-01

    Background Advanced maternal age (AMA) is associated with several adverse pregnancy outcomes, hence these pregnancies are considered to be “high risk.” A review of the empirical literature suggests that it is not clear how women of AMA evaluate their pregnancy risk. This study aimed to address this gap by exploring the risk perception of pregnant women of AMA. Methods A qualitative descriptive study was undertaken to obtain a rich and detailed source of explanatory data regarding perceived pregnancy risk of 15 women of AMA. The sample was recruited from a variety of settings in Winnipeg, Canada. In-depth interviews were conducted with nulliparous women aged 35 years or older, in their third trimester, and with singleton pregnancies. Interviews were recorded and transcribed verbatim, and content analysis was used to identify themes and categories. Results Four main themes emerged: definition of pregnancy risk, factors influencing risk perception, risk alleviation strategies, and risk communication with health professionals. Conclusions Several factors may influence women's perception of pregnancy risk including medical risk, psychological elements, characteristics of the risk, stage of pregnancy, and health care provider’s opinion. Understanding these influential factors may help health professionals who care for pregnant women of AMA to gain insight into their perspectives on pregnancy risk and improve the effectiveness of risk communication strategies with this group.

    Enhanced precipitation due to climate change leads to increase in both frequency and intensity of landslides in Norway. A proactive approach to risk management is therefore required to significantly reduce the losses associated with landslides. Opinions and perceptions from practitioners on the performance of landslide risk management can provide insights on areas for improvement in the landslide risk management strategies in Norway. The Risk Management Index (RMI), proposed by Cardona et al. (2004), is a well-established method to measure perceptions of disaster management of selected actors holistically. The RMI is measured based on opinion questionnaires to technical staff, decision-makers, and stakeholders involved in all stages of risk reduction strategies. It is a composite index that considers a wide variety of strategies to manage risks, including structural and non-structural measures, acceptance strategies, disaster management, and risk transfer. The RMI method was modified to be implemented in landslide hazards and to fit with Norwegian conditions. An opinion survey was conducted in autumn 2015 to measure perceptions of landslide risk management in Norway. Perceptions were surveyed for two time periods: 2015 and 2050, and are based on national, county, and municipality levels. Based on the survey results, performance of landslide risk management at any administrative levels in Norway is perceived to improve from `significant' in 2015 to `significant' to `outstanding' in 2050. Knowledge and technology, climate, risk perceptions, and anthropogenic activities are mostly considered by respondents for their 2050 perceptions. Several aspects of landslide risk management in Norway can be improved. For example, landslide hazard evaluation and mapping should be prioritised in Norway. Upgrading, retrofitting, and reconstruction of assets may also be included in the landslide risk reduction strategies. In addition, there should be more focus on inter

    Starting with 2000, the expert group Society and Policy Support carries out research on various aspects of risk governance. Measuring several risk perception items at regular intervals with the Belgian population is an important part of this research. SCK-CEN has organised a first risk perception barometer in 2002 and a second one in 2006. The 2006 barometer is based on 1063 Computer Assisted Personal Interviews, with a duration of approximately 35 minutes. The large scale of the survey ensures that general trends can be detected and allows specific and detailed analysis on subgroups of the population. Besides the classical background variables used to obtain a sample representative for the Belgian 18+ population (age, language, habitat, gender and social class), several questions were included assessing the sociological context and the psychological personality profile. A series of questions on risk perception, confidence in authorities and specific nuclear topics were repeated in 2006 and constitute a fixed core, allowing comparison over time in Belgium, as well as with the results from the IRSN French barometer. In addition, a number of topics such as acceptance of legal norms and management options for radioactively contaminated milk, energy, nuclear waste and the perception of the Chernobyl accident were covered in detail in the 2006 edition of the SCK-CEN barometer

    Background Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes.

    The extent to which people are willing to take on risk, i.e. their risk preferences as well as subjective risk perception plays a major role in explaining their behavior. This is of particular relevance in agricultural production, which is inherently risky. The data presented here was collected amongst a total of 64 German farmers in 2015. It includes results of three different risk preference elicitation methods (multiple price list, business statements in four relevant domains and general s...

    In industry, because of retirement of postwar baby-boom generation and decreasing labor accident by improvement in facilities, diminished worker's risk perception is concerned about. Although hazard prediction activity (KY: Kiken-Yochi) is carried out for improvement of workers' risk perception in sites, it is get into a rut not to estimate the effects of the activity. Then the purpose of this study is to examine the possibility of measuring and estimating individual inherent risk perception not depending on the experiences and knowledge, and to confirm the effects of the experiences and knowledge on one's risk perception. Eleven subjects were requested to detect the hazards and to estimate the results and the extents of damage in the three films (1: working at an office (all subjects had the experience), 2: feeding at the GS (gas station) (half of them had the experience), 3: overhauling a valve (no one had the experience)) that were included in some hazards. The rate of hazards detection and the accuracies of 5 categories, that were hazards, results, damage of human, damage of objects or facilities and coping, were calculated. The experience of feeding had effects on the rate of hazards detection and some of the accuracies at the film of feeding at the GS. Also, all of indices were significantly lower at the firm of overhauling a valve than the firm of working at an office. These results showed that the experiences and knowledge were affected on one's risk perception. Meanwhile, the similarity of the tendency to the rate of hazards detection and the accuracies between 2 firms except for the firm of feeding was found by means of the ordinal correlation. The result showed that it will be able to measure the individual inherent risk perception from the number of hazards detection and the depth of the context. The future issues are discussed for developing the method to evaluate the risk perception. (author)

  5. Waste-acceptance criteria and risk-based thinking for radioactive-waste classification

    International Nuclear Information System (INIS)

    Lowenthal, M.D.

    1998-01-01

    The US system of radioactive-waste classification and its development provide a reference point for the discussion of risk-based thinking in waste classification. The official US system is described and waste-acceptance criteria for disposal sites are introduced because they constitute a form of de facto waste classification. Risk-based classification is explored and it is found that a truly risk-based system is context-dependent: risk depends not only on the waste-management activity but, for some activities such as disposal, it depends on the specific physical context. Some of the elements of the official US system incorporate risk-based thinking, but like many proposed alternative schemes, the physical context of disposal is ignored. The waste-acceptance criteria for disposal sites do account for this context dependence and could be used as a risk-based classification scheme for disposal. While different classes would be necessary for different management activities, the waste-acceptance criteria would obviate the need for the current system and could better match wastes to disposal environments saving money or improving safety or both

    Hardy, Terry L.

    2005-12-01

    A number of inventors and entrepreneurs are currently attempting to develop and commercially operate reusable launch vehicles to carry voluntary participants into space. The operation of these launch vehicles, however, produces safety risks to the crew, to the space flight participants, and to the uninvolved public. Risk communication therefore becomes increasingly important to assure that those involved in the flight understand the risk and that those who are not directly involved understand the personal impact of RLV operations on their lives. Those involved in the launch vehicle flight may perceive risk differently from those non-participants, and these differences in perception must be understood to effectively communicate this risk. This paper summarizes existing research in risk perception and communication and applies that research to commercial reusable launch vehicle operations. Risk communication is discussed in the context of requirements of United States law for informed consent from any space flight participants on reusable suborbital launch vehicles.

    1990-01-01

    Most analytical assessments of potential impacts on the environment from US Department of Energy (DOE) activities receive, at some point in their development, public scrutiny. The objective of this paper is to discuss the apparent perception of these assessments held by the public reviewers, based on written and verbal comments that they have offered. The discussion begins with a short overview of the analytical assessment process most often used on DOE projects. The process is described in terms of the basic process elements and data sources involved. Based on this outline of the assessment process, the key elements from the public's perspective are identified and examined on the basis of Importance Criteria and the Perception Framework in which the Importance Criteria appear to be applied. The paper is concluded with an analysis of the key elements of the public's perception. This section of the discussion is formatted to couple observational evidence of public perception difficulties with key assessment elements, and these difficulties with potential alternative approaches that serve the same purpose but are more acceptable to the public

    Research by cognitive and social psychologists has demonstrated that when lay persons make estimates of risks they do not merely calculate in terms of probabilistic information. People tend to construe the risk in accordance with other schemata. The Psychometric Paradigm (Slovic et. al., 1980), found out two main dimensions in the perception of risk: the Dread and the Familiarity-Voluntariness factors. This paper presents some of the key findings of a comparative Latin-American study on radiological risk perception in the health area. The main objective is to check whether or not the Dread and the Familiarity-Voluntariness dimensions explain the perception of risk in this specific context. A questionnaire was distributed to outpatient samples from ten countries: Argentine, Brazil, Colombia, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Spain, thanks to the collaboration of the different National Radioprotection Societies of the above mentioned countries, and of other concerned professionals (in case they didn't have any association at the time). A list of 22 risks, including both radiological and non-radiological ones, were evaluated on two rating scales: possibility and seriousness. Factor analysis, both exploratory and confirmatory, as well as Multidimensional Scaling will be used for the data analysis. The paper will discuss the main cross-cultural differences with regard to the structure of risk perception. The peculiarities of the health related risks will be emphasised. (author)

    Technological progress and its impacts on humankind has caused an increasing awareness of risk, and objective, statistical estimations are often inadequate to alleviate the public's fright and fear. Research on risk perception using psychological and sociological approaches is trying to bridge this gap. As a first step, a distinction must be made between the technical definition of risk (probability x consequences) and the social definition, in which additional parameters (source, dimensions, timeframe, exposure) need to be included. The methodology of risk assessment, though objective by design, is limited in the interpretability of its results, if the calculation of consequences does not take public perceptions and social effects into account. The problems and advantages of risk assessment are discussed, and the key questions for risk perception research are presented. Various techniques are available to study risk perception and attitudes towards risk; selection of a specific technique is determined by the objective of the research, namely sociological implications or psychological cognitions. Several empirical studies in both areas are presented and the results discussed.

    Full Text Available Environmental events such as natural disasters may influence the public's affective reactions and decisions. Shortly after the 2004 Tsunami disaster we assessed how affect elicited by thinking about this disaster influenced risk perceptions and future time perspective in Swedish undergraduates not directly affected by the disaster. An experimental manipulation was used to increase the salience of affect associated with the disaster. In Study 1 we found that participants reminded about the tsunami had a sense that their life was more finite and included fewer opportunities than participants in the control condition (not reminded about the tsunami. In Study 2 we found similar effects for risk perceptions. In addition, we showed that manipulations of ease-of-thought influenced the extent to which affect influenced these risk perceptions, with greater ease of thoughts being associated with greater perceived risks.

    Social considerations significantly influence daily purchase decisions, and the perception of social risk (i.e., the anticipated disapproval of others) is crucial in dissuading consumers from making purchases. However, the neural basis for consumers' perception of social risk remains undiscovered, and this novel study clarifies the relevant neural processes. A total of 26 volunteers were scanned while they evaluated purchase intention of products (purchase intention task) and their anticipation of others' disapproval for possessing a product (social risk task), using functional magnetic resonance imaging (fMRI). The fMRI data from the purchase intention task was used to identify the brain region associated with perception of social risk during purchase decision making by using subjective social risk ratings for a parametric modulation analysis. Furthermore, we aimed to explore if there was a difference between participants' purchase decisions and their explicit evaluations of social risk, with reference to the neural activity associated with social risk perception. For this, subjective social risk ratings were used for a parametric modulation analysis on fMRI data from the social risk task. Analysis of the purchase intention task revealed a significant positive correlation between ratings of social risk and activity in the anterior insula, an area of the brain that is known as part of the emotion-related network. Analysis of the social risk task revealed a significant positive correlation between ratings of social risk and activity in the temporal parietal junction and the medial prefrontal cortex, which are known as theory-of-mind regions. Our results suggest that the anterior insula processes consumers' social risk implicitly to prompt consumers not to buy socially unacceptable products, whereas ToM-related regions process such risk explicitly in considering the anticipated disapproval of others. These findings may prove helpful in understanding the mental

    Full Text Available The current work examined the structure of household waste management system, collection and disposal within the context of a wider research on integrated solid waste management in households. A sample of 30 households from eleven selected residential areas with a focus group of 60 respondents in Ojo Local Government Area, Lagos State, Nigeria was used. The selected residential areas were divided into high, middle and low socio-economic strata. The research examined a range of environmental behaviours, attitude and perception of respondents on household solid waste management. The results established waste management behaviours among the respondents on solid waste management system, services, patronage of services and cost recovery methods. Public opinion and perception on solid waste management system is characterized with irregularity and inefficient collection system; with poor monitoring of the private waste service providers by the local authority. Willingness to pay for waste management services provided by the private service providers, the Private Sector Participation operators is higher among the middle and high income socio-economic groups than in the low income group. However, with the application of sustainable environmental education greater success ratio could be achieved. Level of patronage of solid waste management services is high across the three socio-economic groups but patronage is shared among the two operating service providers (formal and informal. The Private Sector Participation has the highest patronage level with 64.6% severity index while the informal sector (Cart pushers have only 48.7% severity index both percentages translate to the agreed and neutral perception opinion ranges respectively. The paper advocates for improved solid waste management system through proper monitoring of the services of the Private Sector Participation operators by the Local Government Area for improved service efficiency.

    Like every year, this report presents and comments the results of an opinion survey on risks, and more particularly on nuclear and radiological risks. The first part addresses the current concerns of French people (the main concerns in the present society and with respect to the environment, how science is considered). The second part addresses the opinion on expertise (who should control a hazardous installation, the role and image of experts, the access to expertise files, the perception of pluralist bodies). The third part examines the reaction of people in front of 33 different hazardous situations (risks to which people feel being exposed, confidence in authorities, confidence in information on hazards, hierarchy of 33 situations and relationship with installation acceptability). The fourth part addresses the nuclear issue (nuclear risk, ability and credibility of nuclear actors, the Chernobyl accident, radioactive wastes, demand of information on the nuclear risk).

    Congress has strengthened the laws under which active hazardous waste facilities are regulated. Nevertheless, after visiting a number of active treatment, storage, and disposal facilities, the Council on Economic Priorities (CEP) found that not only do generators not know which facilities are the best, but that the EPA has not always selected the best facilities to receive wastes removed from Superfund sites. Other facilities were better managed, better located, and better at using more advanced technologies than the facilities the EPA selected. In fact, of the ten facilities CEP evaluated in detail the EPA chose the one that performed worst - CECOS International, Inc. in Williamsburg, Ohio - to receive Superfund wastes in more instances than any of the other nine facilities. Data from a house subcommittee survey indicate that almost half of the operating hazardous waste facilities the EPA chose to receive wastes removed from Superfund sites may have contaminated groundwater. Some of the chosen facilities may even be partially responsible for a share of the wastes they are being paid to clean up. Hazardous waste management strategies and technology, how to evaluate facilities, and case studies of various corporations and hazardous waste management facilities are discussed

    Clinical risk stratification models, such as the CHA2DS2-VASc, are used to assess stroke risk in atrial fibrillation (AF) patients. No study has yet investigated whether and to which extent these patients have a realistic perception of their personal stroke risk. The purpose of this study was to investigate and describe the association between AF patients' stroke risk perception and clinical stroke risk. In an observational cross-sectional study design, we surveyed 178 AF patients with a mean age of 70.6 years (SD 8.3) in stable anticoagulant treatment (65% treatment duration >12 months). Clinical stroke risk was scored through the CHA2DS2-VASc, and patients rated their perceived personal stroke risk on a 7-point Likert scale. There was no significant association between clinical stroke risk assessment and patients' stroke risk perception (rho = .025; P = .741). Approximately 60% of the high-risk patients had an unrealistic perception of their own stroke risk, and there was no significant increase in risk perception from those with a lower compared with a higher risk factor load (χ(2) = .010; P = .522). Considering possible negative implications in terms of lack of motivation for lifestyle behavior change and adequate adherence to the treatment and monitoring of vitamin K antagonist, the apparent underestimation of risk by large subgroups warrants attention and needs further investigation with regard to possible behavioral consequences.

    The Belgian Nuclear Research Center SCK-CEN 2006 risk perception barometer is based on over 1000 Computer Assisted Personal Interviews, taken from persons selected to be representative for the Belgian 18+ population, and all realized in the period March 21st to April 12th 2006. Besides the classical background variables used to obtain the quota for representativity (age, language, habitat, gender and social class), we also included a series of questions assessing the sociological context and the psychological personality profile. The main topics in the survey were I) risk perception and confidence in authorities; II) acceptance of legal norms for food products; III) acceptance of countermeasures for the food chain in case of a radiological contamination and associated consumers behaviour; IV) energy; v) disposal of radioactive waste; vi) perception of the Chernobyl accident and its consequences. Some of the questions asked in 2006 are similar to those enquired in the SCK barometer of 2002, in order to study the time evolution of the risk perception associated with various issues. For the part related to acceptance of legal norms and of countermeasures for the food chain, simulated news bulletins were used in order to better reproduce the real-life context of a contamination.

    The paper concerns a study of peoples' attitude towards the siting of radioactive waste repositories, carried out by the University of Surrey, United Kingdom. The work has been commissioned by the Department of the Environment as part of its radioactive waste management research programme. The people taking part were asked to mark on a map of Great Britain places they felt radioactive waste repositories would be least objectionable. The degree to which people worried about the technology and the management of radioactive waste disposal was monitored. Questions were asked about storage, disposal and transportation aspects, and about present and future worries. (UK)

    The resilience of communities against natural hazards is largely influenced by how the individuals perceive risk. A good understanding of people's risk perception, awareness and hazard knowledge is crucial for developing and improving risk management and communication strategies between authorities and the affected population. A lot of research has been done in investigating the social aspects of risks to natural hazards by means of interviews or questionnaires. However, there is still a lack of research in the investigation of the influence of the spatial distance to a hazard event on peoples risk perception. While the spatial dimension of a natural hazard event is always assessed in works with a natural science approach, it is often neglected in works on social aspects of natural hazards. In the present study, we aimed to overcome these gaps by combining methods from different disciplines and assessing and mapping the spatial pattern of risk perception through multivariate statistical approaches based on empirical data from questionnaires. We will present results from a case study carried out in Badia, located in the Province of South Tyrol- Italy, where in December 2012 a landslide destroyed four residential buildings and led to the evacuation of 36 people. By means of questionnaires distributed to all adults living in the case study area we assessed people's risk perception and asked respondents to allocate their place of residence on a map of the case study area subdivided in 7 zones. Based on the data of the questionnaire results we developed a risk perception factor in order to express various assessed aspects linked to risk perception with one metric. We analyzed and mapped this factor according to the different zones reflecting the spatial distance to the event. Furthermore, a cluster analysis identified various risk behavior profiles within the population. We also investigated the spatial patterns of these risk profiles. We revealed that the residential

    This present work contains the study of risk perception in different areas of interaction. For it was made an analysis using methodology previously recognized and tested: a systematic review in the search for better understanding of the perception of risk in the nuclear area. Through this study it was possible to understand the potential of the systematic review as a tool for information that encompass the perception of risk as a whole. Making it possible to trace parameters to find out why the world's people have an aversion to certain matters relating to nuclear energy. Considering that if you can understand what drives the people has disgust on nuclear area, it is probably possible to create alternatives to remedy this lack of information and knowledge about the area. Causing the population to realize the benefits that nuclear power brings to people. (author)

    Objectives Falls are a leading cause of injury at work, and slipping is the predominant cause of falling. Prior research has suggested a modest correlation between objective measures (such as coefficient of friction, COF) and subjective measures of slipperiness (such as worker perceptions) in the workplace. However, the degree of association between subjective measures and the actual risk of slipping at the workplace is unknown. This study examined the association between perception of slipperiness and the risk of slipping. Methods 475 workers from 36 limited-service restaurants participated in a 12-week prospective cohort study. At baseline, demographic information was collected, participants rated floor slipperiness in eight areas of the restaurant, and work environment factors, such as COF, were measured. Restaurant-level and area-level mean perceptions of slipperiness were calculated. Participants then reported their slip experience at work on a weekly basis for the next 12 weeks. The associations between perception of slipperiness and the rate of slipping were assessed. Results Adjusting for age, gender, body mass index, education, primary language, mean COF, use of slip-resistant shoes, and restaurant chain, each 1-point increase in mean restaurant-level perception of slipperiness (4-point scale) was associated with a 2.71 times increase in the rate of slipping (95% CI 1.25 to 5.87). Results were similar for area-level perception within the restaurant (rate ratios (RR) 2.92, 95% CI 2.41 to 3.54). Conclusions Perceptions of slipperiness and the subsequent rate of slipping were strongly associated. These findings suggest that safety professionals, risk managers and employers could use aggregated worker perceptions of slipperiness to identify slipping hazards and, potentially, to assess intervention effectiveness.

    An analysis of the risk associated with nuclear material recovery and waste preparation is presented. The steps involve: reprocessing of spent fuel to recycle fissionable material, refabrication of the recovered material for use as reactor fuel, and the transportation links connecting these plants with the power plants and waste repositories. The risks considered are radiological and non-radiological, accident and routine effects on the public and workers during plant construction, operation and decommissioning.

    Full text of publication follows: the study of public perceptions of risk has given rise to a number of different (and sometimes conflicting) perspectives. Although the differences between these approaches are not trivial, recent reviews have suggested that there may be some points of convergence. In particular, recent work within the different traditions has emphasised the importance of factors such as trust and power for understanding public perceptions of risk. These factors take us beyond the characteristics of the risks themselves, which were the focus of influential work in the psychometric tradition and into a consideration of the social and cultural context within which potentially hazardous technologies are encountered and evaluated. In this paper we examine the way in which the lay public understand and respond to a particular class of technological risks - those associated with site-based major accident hazards. On the basis of empirical research, we argue that an appreciation of the different contexts within which citizens encounter such risks is crucial to understanding the dynamics of public concerns. We illustrate our argument by examining the different ways in which contextual factors influence perceptions. The discussion draws upon a recently completed study of public perceptions of the risks at seven major hazard sites in the UK, which was funded the by UK Health and Safety Executive. (authors)

    According to recent studies, Spanish adolescents show low perception of risk in alcohol consumption. The current study aims to analyze the factors that favor this low perception based on the opinion of a group of 32 professional experts on adolescence, family, school, mass media, and local policies. A qualitative methodology was used, based on Grounded Theory, using information from 5 focus groups guided by semi-structured interviews. Twelve factors or subcategories were identified, grouped in 4 general categories: short-term risk, immediacy, and perception of invulnerability ("adolescent thinking" category); benevolent view of alcohol, normalization of consumption, and alcohol-entertainment binomial ("social norms" category); parents' habitual consumption, verbal/non-verbal inconsistency in parental model, risk-free consumption depicted in the mass media, consumption with positive results in the media ("social models" category); and excessive health content, long-term risk ("preventive discourse" category). After discussing the results in the context of the current scientific literature, the article offers various proposals for increasing risk perception in adolescents: stronger impact of contents on short-term risks of alcohol; educational strategies targeted to adolescents to include agents of socialization, especially parents; and policies centered on the substance and reduction of supply.

  19. Risk perception and communication in sub-Saharan Africa.

    2012-11-01

    In this narrative review, a brief summary of theoretical approaches to risk perception is followed by an analysis of some of the special factors influencing risk perception and risk communication in sub-Saharan Africa. Examples of recent and emergent local medicines and vaccine controversies in several countries are given along with evidence and analysis of how they were managed. These demonstrate, among other things, the extent to which ethnic, religious and cultural issues influence popular perception, and the power of rumour and anecdote in shaping public opinion and official responses to events. Where safety monitoring systems exist, they are in their infancy, with limited capacity for data collection, credible scientific review, effective public communication and robust crisis management. Although increasing democratic freedoms, including less restricted media, and evolving health systems are addressing the challenges and give hope for further progress, there are still deep and intractable issues that inhibit transparent and effective risk communication and stand in the way of African populations comprehending medicines and their risks in safer and more balanced ways. Some proposals for future change and action are offered, including the pursuit of a deeper understanding of local and national values, assumptions and beliefs that drive risk perception; tailoring public health planning and communications to specifically-targeted regions and populations; strengthening of safety surveillance and data-collection systems; giving higher priority to medicines safety issues in healthcare training and public education.

    Effective risk communication in transfusion medicine is important for health-care consumers, but understanding the numerical magnitude of risks can be difficult. The objective of this study was to determine the effect of a visual risk communication tool on the knowledge and perception of transfusion risk. Laypeople were randomly assigned to receive transfusion risk information with either a written or a visual presentation format for communicating and comparing the probabilities of transfusion risks relative to other hazards. Knowledge of transfusion risk was ascertained with a multiple-choice quiz and risk perception was ascertained by psychometric scaling and principal components analysis. Two-hundred subjects were recruited and randomly assigned. Risk communication with both written and visual presentation formats increased knowledge of transfusion risk and decreased the perceived dread and severity of transfusion risk. Neither format changed the perceived knowledge and control of transfusion risk, nor the perceived benefit of transfusion. No differences in knowledge or risk perception outcomes were detected between the groups randomly assigned to written or visual presentation formats. Risk communication that incorporates risk comparisons in either written or visual presentation formats can improve knowledge and reduce the perception of transfusion risk in laypeople.

    In two experiments, the impact of shopping context on consumers' risk perceptions and regulatory focus was examined. We predicted that individuals perceive an online (vs. conventional) shopping environment as more risky and that an online shopping environment, by its risky nature, primes a prevention focus. The findings in Study 1 demonstrate these effects by using self-report measures for risk perception and prevention focus. In Study 2, we replicated these findings and demonstrated that the effect of an online shopping environment carries over to behavior in a domain unrelated to shopping.

    Previous research suggested that illness perceptions provide the basis for illness risk perceptions through an inductive reasoning process. This study aimed to assess the direction of relationships between illness and recurrence risk perceptions over time, among cardiac patients. A longitudinal study was conducted among 138 patients undergoing coronary angioplasty. Self-report questionnaires measured perceived recurrence risk and illness perceptions one day and one month after catheterisation. Cross-lagged Panel Model Analyses revealed that higher perceptions of timeline, consequences and emotional representations of illness at hospitalisation were associated with higher recurrence risk perceptions one month later. Perceived personal control was the only illness perception with bi-directional associations: higher perceived personal control at hospitalisation was associated with higher recurrence risk perceptions one month later; and higher recurrence risk perceptions at hospitalisation was associated with lower personal control one month later. The findings suggest that the associations between recurrence risk and illness perceptions can only partly be explained by inductive reasoning. Halo effects and defensive processes are suggested as complementary explanations for the observed associations between risk and illness perceptions.

    This study aims at investigating laymens' experiences of risk in connection with storage of nuclear waste. The data consisted of interviews. To begin with, a pilot study was conducted using 14 subjects, with the aim of generating issues that could be further penetrated in the main study. The main study consisted of interviews with 30 subjects. The final data analysis was based on 25 subjects' answers to the interviews, with 5 of the 30 persons omitted due to contradictory and extremely vague answers, making any coherent interpretation impossible. The results section is divided into 3 parts. The first clarifies the conditions for the possibility of experiencing risk. These conditions are so general that they are most likely valid as conditions for any kind of risk experience. The second part of the results section consists of a presentation and clarification of the components which made up the subjects experiences of risk in connection with storage of nuclear waste. The third and final part of the results section consists of a presentation of the two main profiles in the experience of risk in connection with storage of nuclear waste. These two main profiles can be conceived of as opposites. One of the risk profiles was constituted in the following way; a perception of the risk as high, a negative attitude to nuclear energy, presence of emotional expression, distrust towards significant people, an assumption that experts lacked sufficient knowledge and a focusing or widening frame of reference. The other main profile was constituted as follows; a perception of the risk as not high, an absence of emotional expression, trust towards significant people, an assumption that experts possessed sufficient knowledge and a focusing or weighing frame of reference

    Full Text Available Introduction and purpose: Improper management of healthcare waste (HCW can pose considerable risks to human health and the environment and cause serious problems in developing countries such as Iran. In this study, we sought to determine the hazards of HCW in the public hospitals affiliated to Abadan School of Medicine using the preliminary hazard analysis (PHA method. Methods: In this descriptive and analytic study, health risk assessment of HCW in government hospitals affiliated to Abadan School of Medicine (4 public hospitals was carried out by using PHA in the summer of  2016. Results: We noted the high risk of sharps and infectious wastes. Considering the dual risk of injury and disease transmission, sharps were classified in the very high-risk group, and pharmaceutical and chemical and radioactive wastes were classified in the medium-risk group. Sharps posed the highest risk, while pharmaceutical and chemical wastes had the lowest risk. Among the various stages of waste management, the waste treatment stage was the most hazardous in all the studied hospitals. Conclusion: To diminish the risks associated with healthcare waste management in the studied hospitals, adequate training of healthcare workers and care providers, provision of suitable personal protective and transportation equipment, and supervision of the environmental health manager of hospitals should be considered by the authorities.

    The measures that are applied to regulate a certain practice, are based on the risk that implies the practice and in the acceptance of the above mentioned risk from the part affected by the practice. If the perception of the risk does not correspond to the reality the situation is unstable and it is possible to lose the control of the situation. When discrepancies exist in the Perception of the Risk on the part of different sectors of the society, they can produce serious conflicts that affect the establishment of the protection measures. The problem of the 'perception of the risk' rests on the fact that the technical people and the public use generally different reasoning and therefore its coincidence is almost fortuitous. The intuitive perception of the risk is often narrowly tied to a 'symbolic mechanism' and once established the symbolic relation can produce a psychological phenomenon by means of which the individuals resist to the reality, and the symbols make prevail over the facts in order not to alter the interior symbolic pre-established scheme. The perception of the risk appears in two different groups of persons: 1) The persons affected by the risk (the public); and 2) The persons who can modify this risk (operators). It is important that the perception of the risk is compatible with the scientific hypotheses to avoid conflicts in the situation 1 and to assure the control in the situation 2 (safety culture). The 'perception of the risk' is fundamental to support the control of a practice and it is possible to modify it across the communication. It is necessary to know which are all The Factors that affect the perception of the risk to be able to design a strategy of suitable communication. Across different studies it has been learned which are the factors that affect the perception of risk: 1) Some factors depend on the proper characteristics of the risk; 2) Others depend on the proper characteristics of the individuals and finally; 3) Other factors

    Conventional solid waste management planning usually focuses on economic optimization, in which the related environmental impacts or risks are rarely considered. The purpose of this paper is to illustrate the methodology of how optimization concepts and techniques can be applied to structure and solve risk management problems such that the impacts of air pollution, leachate, traffic congestion, and noise increments can be regulated in the iong-term planning of metropolitan solid waste management systems. Management alternatives are sequentially evaluated by adding several environmental risk control constraints stepwise in an attempt to improve the management strategies and reduce the risk impacts in the long run. Statistics associated with those risk control mechanisms are presented as well. Siting, routing, and financial decision making in such solid waste management systems can also be achieved with respect to various resource limitations and disposal requirements.

  12. Perception of injury risk among amateur Muay Thai fighters.

    Muay Thai is a style of kickboxing that allows full-contact blows to an unprotected head, torso and legs, and, as in any combat sport, there is an inherent risk of injury. Previous observational studies have shown there is a substantial risk of injury in competitive kickboxing. None of these studies, however, have investigated the potential role of psychological risk factors and, consequently, little is known about the perception of injury risk among these athletes. Notwithstanding the important role risk perception may play in the occurrence and prevention of sports injuries, there is very limited empirical data pertaining to athletes in full-contact combat sports such as Muay Thai. Because the development and successful implementation of effective injury prevention policies for combat sports are likely to benefit from an increased understanding of the perception of injury risk and sport safety attitudes and behavior of its participants, further study is warranted. Muay Thai fighters were invited to complete an online survey in which they rated the perceived risk of injury in a range of different sports, including Muay Thai kickboxing. Perceived comparative risk was obtained indirectly by subtracting perceived risk of injury to oneself from perceived risk of injury to a peer. Data were analyzed using descriptive statistics, comparison of means, and ordinal logistic regression. Contrary to the best available epidemiological evidence, Muay Thai fighters perceived the risk of injury in their own sport to be average and significantly lower than that in other collision and contact sports, including popular combat sports such as boxing and mixed martial arts. On average, Muay Thai fighters perceived their own risk injury to be significantly lower compared to their peers (p injury risk perception and actual risk among Muay Thai fighters. Moreover, these athletes also exhibit a slight degree comparative optimism or unrealistic optimism. Because behavior is determined by

    Regarding radiation risk individual coping strategies range from apathy, no worry, avoidance, information seeking, changes in life style, inter alia. How they occur and when, is a necessary information for the development of better risk communication programmes. To address these points four particular situations involving radiation were chosen, namely indoor radon exposure, X-ray diagnostic, consumption of irradiated food, and radioactive waste management. Situations correspond to very different contexts, natural exposure (with indoor radon), daily life (with medical diagnostic and food consumption) and the industrial and energy context (with waste). From a cross-cultural perspective it was deemed fruitful to compare these situations in various countries. (author)

    Cardiovascular disease (CVD) has emerged as a major cause of morbidity and mortality in HIV-infected adults. Research in noninfected populations has suggested that knowledge of CVD risk factors significantly influences perceptions of risk. This cross-sectional study describes CVD risk factor knowledge and risk perception in HIV-infected adults. We recruited 130 HIV-infected adults (mean age = 48 years, 62% male, 56% current smokers, mean years since HIV diagnosis, 14.7). The mean CVD risk factor knowledge score was fairly high. However, controlling for age, CVD risk factor knowledge was not predictive of perceived risk [F(1, 117) = 0.13, p > .05]. Estimated risk and perceived risk were weakly but significantly correlated; r (126) = .24, p = .01. HIV-infected adults are at increased risk for CVD. Despite having adequate risk-factor knowledge, CVD risk perception was inaccurate. Improving risk perception and developing CVD risk reduction interventions for this population are imperative.

    Although risk perception is a key predictor in health behavior theories, current conceptions of risk comprise only one (deliberative) or two (deliberative vs. affective/experiential) dimensions. This research tested a tripartite model that distinguishes among deliberative, affective, and experiential components of risk perception. In two studies, and in relation to three common diseases (cancer, heart disease, diabetes), we used confirmatory factor analyses to examine the factor structure of the tripartite risk perception (TRIRISK) model and compared the fit of the TRIRISK model to dual-factor and single-factor models. In a third study, we assessed concurrent validity by examining the impact of cancer diagnosis on (a) levels of deliberative, affective, and experiential risk perception, and (b) the strength of relations among risk components, and tested predictive validity by assessing relations with behavioral intentions to prevent cancer. The tripartite factor structure was supported, producing better model fit across diseases (studies 1 and 2). Inter-correlations among the components were significantly smaller among participants who had been diagnosed with cancer, suggesting that affected populations make finer-grained distinctions among risk perceptions (study 3). Moreover, all three risk perception components predicted unique variance in intentions to engage in preventive behavior (study 3). The TRIRISK model offers both a novel conceptualization of health-related risk perceptions, and new measures that enhance predictive validity beyond that engendered by unidimensional and bidimensional models. The present findings have implications for the ways in which risk perceptions are targeted in health behavior change interventions, health communications, and decision aids.

  16. Perception of risk and the attribution of responsibility for accidents.

    Accidents, one often hears, "happen"; we accept, and even expect, that they will be part of daily life. But in situations in which injury or death result, judgments of responsibility become critical. How might our perceptions of risk influence the ways in which we allocate responsibility for an accident? Drawing from attribution and risk perception theory, this study investigates how perceived controllability and desirability of risk, in addition to perceived danger and recreational risk-taking, relate to attributions of responsibility for the cause of unintentional injury in a unique setting: U.S. national parks. Three parks, Mount Rainier, Olympic, and Delaware Water Gap, provide the setting for this survey-based study, which considers how park visitors (N = 447) attribute responsibility for the cause of a hypothetical visitor accident. Results suggest that respondents tended to make more internal (i.e., related to characteristics of the victim), rather than external (i.e., related to characteristics of the park, or park management) attributions. As respondents viewed park-related risk as controllable, they were more likely to attribute the cause of the accident to the victim. Moreover, among other significant variables, having experienced a similar accident predicted lower internal causal attribution. Opportunities for future research linking risk perception and attribution variables, as well as practical implications for the management of public outdoor settings, are presented. © 2013 Society for Risk Analysis.

    Few studies have investigated how gamblers perceive risk or the role of risk perception in disordered gambling. The purpose of the current study therefore was to obtain data on lay gamblers' beliefs on these variables and their effects on decision-making, behaviour, and disordered gambling aetiology. Fifteen regular lay gamblers (non-problem/low risk, moderate risk and problem gamblers) completed a semi-structured interview following mental models and grounded theory methodologies. Gambler interview data was compared to an expert 'map' of risk-perception, to identify comparative gaps or differences associated with harmful or safe gambling. Systematic overlapping processes of data gathering and analysis were used to iteratively extend, saturate, test for exception, and verify concepts and themes emerging from the data. The preliminary findings suggested that gambler accounts supported the presence of expert conceptual constructs, and to some degree the role of risk perception in protecting against or increasing vulnerability to harm and disordered gambling. Gambler accounts of causality, meaning, motivation, and strategy were highly idiosyncratic, and often contained content inconsistent with measures of disordered gambling. Disordered gambling appears heavily influenced by relative underestimation of risk and overvaluation of gambling, based on explicit and implicit analysis, and deliberate, innate, contextual, and learned processing evaluations and biases.

    This paper explores and quantifies the recent Wall Street fears concerning nuclear utilities. An econometric model of investor behavior is presented that quantifies the nuclear risk premium for the period when nuclear fear among investors was at its height, in mid-1984. The principal finding is that the risk premium relates primarily to nuclear construction work in progress (CWIP), rather than to the commercial operation of completed nuclear plants. 7 references, 1 table

    2012-04-01

    In the last decade, in most of the European countries risk maps on natural hazards have been elaborated but there is so far little experience how to efficiently communicate these maps to the public. Recently, the public authorities of Zurich informed the owners of buildings located within the hazard zone on urban flood risks The owners received official letters containing information on potential danger, the probability of flood events, constructional safety measures, and guidelines for appropriate actions in case of an immediate flood. In the cover letter they were also encouraged to achieve more detailed information about the particular risks for their building using an online accessible risk map within a geographic information system (GIS). This risk communication campaign was based on the expectation that informing citizens increases their risk awareness and that citizens aware of risks are more likely to undertake actions to protect themselves and their property. There is, however, little empirical evidence that these expected outcomes can be achieved by written forms of risk communication. With this project we aim to find out to which degree a campaign of written risk communication can shape land owners risk perception and risk behaviour, and which other factors (e.g. trust in authorities, risk, risk zone category of the building) contributed to these outcomes... In collaboration with public authorities we conducted a survey among 1500 owners of buildings in the hazard zones in Zurich (50 % in blue zone, 50 % in yellow and yellow-white zone), that is 14% of all persons who were addressed by the authorities of the city. The standardized questionnaire comprises in particular items measuring respondents' evaluation of the virtual and physical information material, the time they spent for studying the information material, the dimensions of their risk perception, their acceptability of risks and their preparedness to implement constructional and other safety

    We explored the risky driving behaviors and risk perceptions of a cohort of young novice drivers and sought to determine their associations with crash risk. Provisional drivers aged 17 to 24 (n = 20 822) completed a detailed questionnaire that included measures of risk perception and behaviors; 2 years following recruitment, survey data were linked to licensing and police-reported crash data. Poisson regression models that adjusted for multiple confounders were created to explore crash risk. High scores on questionnaire items for risky driving were associated with a 50% increased crash risk (adjusted relative risk = 1.51; 95% confidence interval = 1.25, 1.81). High scores for risk perception (poorer perceptions of safety) were also associated with increased crash risk in univariate and multivariate models; however, significance was not sustained after adjustment for risky driving. The overrepresentation of youths in crashes involving casualties is a significant public health issue. Risky driving behavior is strongly linked to crash risk among young drivers and overrides the importance of risk perceptions. Systemwide intervention, including licensing reform, is warranted.

  3. A metasynthesis of risk perception in women with high risk pregnancies.

    risk perception in women with high risk pregnancies affects their decisions about perinatal care and is of interest to anyone involved in the care of pregnant women. This paper provides a metasynthesis of qualitative studies of risk perception in women with high risk pregnancies. a systematic search of eight electronic databases was conducted. Additional papers were obtained through searching references of identified articles. Six studies were identified that reported qualitative research into risk perception in relation to high risk pregnancy. A metasynthesis was developed to describe and interpret the studies. the synthesis resulted in the identification of five themes: determinants of risk perception; not seeing it the way others do; normality versus risk; if the infant is ok, I׳m ok; managing risk. this metasynthesis suggests women at high risk during pregnancy use multiple sources of information to determine their risk status. It shows women are aware of the risks posed by their pregnancies but do not perceive risk in the same way as healthcare professionals. They will take steps to ensure the health of themselves and their infants but these may not include following all medical recommendations. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The complexities of our political and legal systems, along with both insufficient information and misinformation, has resulted in significant problems in the disposal of radioactive waste. Distrust of the industry and regulators by the public, along with insufficient understanding of public fear by those responsible for waste disposal, has created a delay which shows few signs of early resolution. In light of these problems, this paper will specifically cover low-level radioactive waste disposal and management issues in the Appalachian Compact state of Pennsylvania. It will focus on the public's perception of waste technologies, and related policy issues, and the necessity of research and public education to create a bridge of understanding between those responsible for disposing of this material, those who benefit (the general public) from the creation of the waste, and those who are asked to live near disposal sites

    The United States Department of Energy (DOE) Hanford Site recently has undergone a significant change in mission. The focus of operations has shifted from plutonium production to environmental restoration. This transition has caused a substantial increase in quantities of nuclear waste and other hazardous materials packaged and transported onsite. In response to the escalating transportation activity, Westinghouse Hanford Company (Westinghouse Hanford), the Hanford Site operations and engineering contractor, is proposing an integrated risk assessment methodology and risk management strategy to enhance the safety of onsite packaging and transportation operations involving nuclear waste. The proposed methodology consists of three integral parts: risk assessment, risk acceptance criteria, and risk minimization. The purpose of the methodology is to ensure that the risk for each ongoing transportation activity is acceptable and to minimize the overall risk for current and future onsite operations.

    Slovic, P; MacGregor, D; Kraus, N N

    1987-10-01

    Descriptions of safety engineering defects of the kind that compel automobile manufacturers to initiate a recall campaign were evaluated by individuals on a set of risk characteristic scales that included overall vehicle riskiness, manufacturer's ability to anticipate the defect, importance for vehicle operation, severity of consequences and likelihood of compliance with a recall notice. A factor analysis of the risk characteristics indicated that judgments could be summarized in terms of two composite scales, one representing the uncontrollability of the damage the safety defect might cause and the other representing the foreseeability of the defect by the manufacturer. Motor vehicle defects were found to be highly diverse in terms of the perceived qualities of their risks. Location of individual defects within the factor space was closely associated with perceived riskiness, perceived likelihood of purchasing another car from the same manufacturer, perceived likelihood of compliance with a recall notice, and actual compliance rates.

    Full Text Available Abstract Background Counselees are more aware of genetics and seek information, reassurance, screening and genetic testing. Risk counseling is a key component of genetic counseling process helping patients to achieve a realistic view for their own personal risk and therefore adapt to the medical, psychological and familial implications of disease and to encourage the patient to make informed choices 12. The aim of this study was to conceptualize risk perception and anxiety about cancer in individuals attending to genetic counseling. Methods The questionnaire study measured risk perception and anxiety about cancer at three time points: before and one week after initial genetic counseling and one year after completed genetic investigations. Eligibility criteria were designed to include only index patients without a previous genetic consultation in the family. A total of 215 individuals were included. Data was collected during three years period. Results Before genetic counseling all of the unaffected participants subjectively estimated their risk as higher than their objective risk. Participants with a similar risk as the population overestimated their risk most. All risk groups estimated the risk for children's/siblings to be lower than their own. The benefits of preventive surveillance program were well understood among unaffected participants. The difference in subjective risk perception before and directly after genetic counseling was statistically significantly lower in all risk groups. Difference in risk perception for children as well as for population was also statistically significant. Experienced anxiety about developing cancer in the unaffected subjects was lower after genetic counseling compared to baseline in all groups. Anxiety about cancer had clear correlation to perceived risk of cancer before and one year after genetic investigations. The affected participants overestimated their children's risk as well as risk for anyone in

    While risk perception is a key factor influencing safety behavior, the academia lacks specific attention to the ways that workers perceive risk, and thus little is known about the mechanisms through which different risk perceptions influence safety behavior. Most previous research in the workplace safety domain argues that people tend to perceive risk based on rational formulations of risk criticality. However, individuals' emotions can be also useful in understanding their perceptions. Therefore, this research employs an integrated analysis concerning the rational and emotional perspectives. Specifically, it was expected that the identified three rational ways of perceiving risk, i.e., perceived probability, severity, and negative utility, would influence the direct emotional risk perception. Furthermore, these four risk perceptions were all expected to positively but differently influence safety behavior. The hypotheses were tested using a sample of 120 construction workers. It was found that all the three rational risk perceptions significantly influenced workers' direct perception of risk that is mainly based on emotions. Furthermore, safety behavior among workers relied mainly on emotional perception but not rational calculations of risk. This research contributes to workplace safety research by highlighting the importance of integrating the emotional assessment of risk, especially when workers' risk perception and behavior are concerned. Suggested avenues for improving safety behavior through improvement in risk perception include being aware of the possibility of different ways of perceiving risk, promoting experience sharing and accident simulation, and uncovering risk information.

    Local public resistance can block the site-selection process, construction, and operation of nuclear waste repositories. Social science has established that the perception of risks and benefits, trust in authorities, and opinion on nuclear energy play important roles in acceptance. In particular, risk and benefit evaluations seem critical for opinion formation. However, risks and benefits have rarely been studied independently and, most often, the focus has been on the two most salient groups of proponents and opponents. The aim of this exploratory study is to examine the often-neglected majority of people holding ambivalent or indifferent opinions. We used cluster analysis to examine the sample (N = 500, mailed survey in German-speaking Switzerland) in terms of patterns of risk and benefit perception. We reveal four significantly different and plausible clusters: one cluster with high-benefit ratings in favor of a repository and one cluster with high-risk ratings opposing it; a third cluster shows ambivalence, with high ratings on both risk and benefit scales and moderate opposition, whereas a fourth cluster seems indifferent, rating risks and benefits only moderately compared to the ambivalent cluster. We conclude that a closer look at the often neglected but considerable number of people with ambivalent or indifferent opinions is necessary. Although the extreme factions of the public will most probably not change their opinion, we do not yet know how the opinion of the ambivalent and indifferent clusters might develop over time. © 2012 Society for Risk Analysis.

    This study investigated the influence of personality characteristics and gender on adolescents' perception of risk and their risk-taking behaviour. Male and female participants (157 females: 116 males, aged 13-20) completed self-report measures on risk perception, risk-taking and personality. Male participants perceived behaviours as less risky, reportedly took more risks, were less sensitive to negative outcomes and less socially anxious than female participants. Path analysis identified a model in which age, behavioural inhibition and impulsiveness directly influenced risk perception, while age, social anxiety, impulsiveness, sensitivity to reward, behavioural inhibition and risk perception itself were directly or indirectly associated with risk-taking behaviour. Age and behavioural inhibition had direct relationships with social anxiety, and reward sensitivity was associated with impulsiveness. The model was representative for the whole sample and male and female groups separately. The observed relationship between age and social anxiety and the influence this may have on risk-taking behaviour could be key for reducing adolescent risk-taking behaviour. Even though adolescents may understand the riskiness of their behaviour and estimate their vulnerability to risk at a similar level to adults, factors such as anxiety regarding social situations, sensitivity to reward and impulsiveness may exert their influence and make these individuals prone to taking risks. If these associations are proven causal, these factors are, and will continue to be, important targets in prevention and intervention efforts.

    Transgender women experience a variety of factors that may contribute to HIV risk. The purpose of this study was to explore links among HIV risk perception, knowledge, and sexual risk behaviors of transgender women. A descriptive, correlational study design was used. Fifty transgender women from the South Florida area were enrolled in the study. Transgender women completed a demographic questionnaire and standardized instruments measuring HIV risk perception, knowledge, and sexual risk behaviors. Transgender women reported low levels of HIV risk perception, and had knowledge deficits regarding HIV risk/transmission. Some participants engaged in high-risk sexual behaviors. Predictors of sexual risk behaviors among transgender women were identified. More research is needed with a larger sample size to continue studying factors that contribute to sexual risk behaviors in the understudied population of transgender women. Evidence-based guidelines are available to assist public health nurses in providing care for transgender women. Nurses must assess HIV perception risk and HIV knowledge and provide relevant education to transgender women on ways to minimize sexual risk. © 2016 Wiley Periodicals, Inc.

    The Fuel Cycle Risk Analysis Division of Sandia Laboratories is funded by the Nuclear Regulatory Commission (NRC) to develop a methodology for assessment of the long-term risks from radioactive waste disposal in deep, geologic media. The first phase of this work, which is documented in this report, involves the following: (1) development of analytical models to represent the processes by which radioactive waste might leave the waste repository, enter the surface environment and eventually reach humans and (2) definition of a hypothetical ''reference system'' to provide a realistic setting for exercise of the models in a risk or safety assessment. The second phase of this work, which will be documented in a later report, will involve use of the analytical models in a demonstration risk or safety assessment of the reference system. The analytical methods and data developed in this study are expected to form the basis for a portion of the NRC repository licensing methodology

    Nuclear waste has become the prime target for an increasingly concerned public over the acceptability of technological risks. In recent times the major conflict is about the distribution and the tolerability of risks for different social groups, regions, and future generations. This shift of focus implies new forms of conflict resolution and underlines the importance of communication as a necessary, though not sufficient, step towards a social equilibrium. Interest of public institutions and academia in risk communication has considerably grown during the last five years. Risk communication has become a popular topic in the literature. Risk communication can serve many purposes ranging from enlightenment, to inducing behavioral changes, to conflict resolution. The crucial issue of how the media shape the perception of risk among individuals and social groups is discussed, and how trust and credibility have become major agents in the public communication process. Some advices are given for risk managers, in particular those dealing with nuclear waste, about potential improvement in their risk communication efforts. (R.P.)

    Full Text Available Abstract Consumer behaviors are more important in the study of Green Marketing. This studied aims to examined buying behavior of consumers on organic products which is formed by perception of quality and perception of risk. The research model with three hypotheses to explained the relationship and influenced between the constructs that perception of quality perception of risk and purchase decision. In these empirical studied treated 366 respondents from customer of retail supermarkets in West Java - Indonesia. Results of research founded a significant negative relationship between perception of quality and perception of risk. As well as the behavior of perception of quality and the perception of risk has a significant influenced on purchase decision. Retail self-service needs to improve the perception of quality and reduces the risk perception of the consumers if purchasing behavior of consumers want increase on organic products. This studied was useful in raising awareness of self-service retail and consumers for environmentally friendly products.

    and farm management training are considered among the best methods to manage the risks in the shrimp-farming business. We also observe some disparities in farmers' perceptions. For instance, farmers mentioned that removal of influence of middlemen from supply chain is essential for the betterment......Aquaculture farmers' risk perceptions and risk management strategies have still received little attention in agricultural research. Therefore, an exploratory study has been undertaken to provide empirical insight into Bangladeshi coastal shrimp farmers' risk perceptions and risk management...... and availability of quality shrimp seeds, exploitation by intermediaries and uncertainty about the future demand for shrimp in foreign markets are perceived as the most important sources of risk. On the other hand, prevention of disease, timely supply of shrimp seeds, elimination of middlemen from the supply chain...

    The TWRS Characterization Project has developed a process and plan in order to identify, manage and control the risks associated with tank waste characterization activities. The result of implementing this process is a defined list of programmatic risks (i.e. a risk management list) that are used by the Project as management tool. This concept of risk management process is a commonly used systems engineering approach which is being applied to all TWRS program and project elements. The Characterization Project risk management plan and list are subset of the overall TWRS risk management plan and list

    This risk management plan defines the approach to be taken to managing risks in the Tank Waste Remediation System (TWRS) program. It defines the actions to be taken at the overall program level, and the risk management requirements for lower-level projects and other activities. The primary focus of this plan is on ''programmatic'' risks, i.e., risks with respect to the cost, schedule, and technical performance of the program. The plan defines an approach providing managers with the flexibility to manage risks according to their specific needs, yet creates. The consistency needed for effectiveness across the program. The basic risk management approach uses a risk management list for the program, each project, and additional lower-level activities. The risk management list will be regularly reviewed and updated by appropriate level of management. Each list defines key risks, their likelihood and consequences, risk management actions to be taken, responsible individuals, and other management information

    The mission of the US Department of Energy's (DOE'S) Mixed Waste Integrated Program (MWIP) is to develop complete and appropriate technologies for the treatment of DOE mixed low-level waste and transuranic wastes in order to ensure that all affected DOE installations and projects can come into compliance with environmental law and meet DOE's 30-yr cleanup and operational goals. The MWIP will achieve its goal by developing technologies that are in compliance with regulatory requirements, are socially and politically viable, and are cost beneficial and effective in disposed waste source term and volume reduction. The project management plan for MWIP requires that technologies be evaluated in accordance with criteria that rank technologies with regard to performance, risk, and cost-effectiveness. This paper addresses the methodology used to rank alternative mixed-water treatment technologies with regard to relative risk

  16. On risk assessment of high level radioactive waste disposal

    International Nuclear Information System (INIS)

    Smith, C.F.; Kastenberg, W.E.

    1976-01-01

    One of the major concerns with the continued growth of the nuclear power industry is the production of the high level radioactive wastes. The risks associated with the disposal of these wastes derives from the potential for release of radioactive materials into the environment. The development of a methodology for risk analysis is carried out. The methodology suggested involves the probabilistic analysis of a general accident consequence distribution. In this analysis, the frequency aspect of the distribution is treated separately from the normalized probability function. In the final stage of the analysis, the frequency and probability characteristics of the distribution are recombined to provide an estimate of the risk. The characterization of the radioactive source term is accomplished using the ORIGEN computer code. Calculations are carried out for various reactor types and fuel cycles, and the overall waste hazard for a projected 35 year nuclear power program is determined. An index of relative nuclide hazard appropriate to problems involving the management of high level radioactive wastes is developed. As an illustration of the methodology, risk analyses are made for two proposed methods for waste management: extraterrestrial disposal and interim surface storage. The results of these analyses indicate that, within the assumptions used, the risks of these management schemes are small compared with natural background radiation doses. (Auth.)

    to explore perceptions and examples of risk related to pregnancy and childbirth in rural and remote Australia and how these influence the planning of maternity services. data collection in this qualitative component of a mixed methods study included 88 semi-structured individual and group interviews (n=102), three focus groups (n=22) and one group information session (n=17). Researchers identified two categories of risk for exploration: health services risk (including clinical and corporate risks) and social risk (including cultural, emotional and financial risks). Data were aggregated and thematically analysed to identify perceptions and examples of risk related to each category. fieldwork was conducted in four jurisdictions at nine sites in rural (n=3) and remote (n=6) Australia. 117 health service employees and 24 consumers. examples and perceptions relating to each category of risk were identified from the data. Most medical practitioners and health service managers perceived clinical risks related to rural birthing services without access to caesarean section. Consumer participants were more likely to emphasise social risks arising from a lack of local birthing services. our analysis demonstrated that the closure of services adds social risk, which exacerbates clinical risk. Analysis also highlighted that perceptions of clinical risk are privileged over social risk in decisions about rural and remote maternity service planning. a comprehensive analysis of risk that identifies how social and other forms of risk contribute to adverse clinical outcomes would benefit rural and remote people and their health services. Formal risk analyses should consider the risks associated with failure to provide birthing services in rural and remote communities as well as the risks of maintaining services.

    Transports of radioactive waste from nuclear facilities have been a matter of frequent public concern in the recent past. News reports, protests and questions concerning the radiological risk tended to concentrate on transports to and from central waste management facilities, e.g. transports of spent fuel elements to reprocessing plants abroad (France, England), transports to intermediate storage sites (Ahaus, Gorleben), transports to operative (Morsleben) and projected (Konrad) final storage sites, and transports of vitrified high-activity waste from reprocessing plants to the intermediate storage site (Gorleben).

    Fisher, J.E.; Falconer, K.L.

    1984-01-01

    A probabilistic risk assessment method is presented for performance evaluation of low-level waste disposal facilities. The associated program package calculates the risk associated with postulated radionuclide release and transport scenarios. Risk is computed as the mathematical product of two statistical variables: the dose consequence of a given release scenario, and its occurrence probability. A sample risk calculation is included which demonstrates the method. This PRA method will facilitate evaluation of facility performance, including identification of high risk scenarios and their mitigation via optimization of site parameters. The method is intended to be used in facility licensing as a demonstration of compliance with the performance objectives set forth in 10 CFR Part 61, or in corresponding state regulations. The Low-Level Waste Risk Methodology is being developed under sponsorship of the Nuclear Regulatory Commission

    2011-11-01

    In Malaysia technologically enhanced naturally occurring radioactive materials (TENORM) wastes are mainly the product of the oil and gas industry and mineral processing. Among these TENORM wastes are tin tailing, tin slag, gypsum and oil sludge. Mineral processing and oil and gas industries produce large volume of TENORM wastes that has become a radiological concern to the authorities. A study was carried out to assess the radiological risk related to workers working at these disposal sites and landfills as well as to the members of the public should these areas be developed for future land use. Radiological risk was assessed based on the magnitude of radiation hazard, effective dose rates and excess cancer risks. Effective dose rates and excess cancer risks were estimated using RESRAD 6.4 computer code. All data on the activity concentrations of NORM in wastes and sludges used in this study were obtained from the Atomic Energy Licensing Board, Malaysia, and they were collected over a period of between 5 and 10 y. Results obtained showed that there was a wide range in the total activity concentrations (TAC) of nuclides in the TENORM wastes. With the exception of tin slag and tin tailing-based TENORM wastes, all other TENORM wastes have TAC values comparable to that of Malaysia's soil. Occupational Effective Dose Rates estimated in all landfill areas were lower than the 20 mSv y(-1) permissible dose limit. The average Excess Cancer Risk Coefficient was estimated to be 2.77×10(-3) risk per mSv. The effective dose rates for residents living on gypsum and oil sludge-based TENORM wastes landfills were estimated to be lower than the permissible dose limit for members of the public, and was also comparable to that of the average Malaysia's ordinary soils. The average excess cancer risk coefficient was estimated to be 3.19×10(-3) risk per mSv. Results obtained suggest that gypsum and oil sludge-based TENORM wastes should be exempted from any radiological regulatory

    Full text: West Africa is one of the Africa's most populated regions, with a total population of approximately 200 million people. The West African sub-region comprises of sixteen different countries, which are as follows: Nigeria, Benin, Togo, Ghana, Code Ivore, Guinea, Guinea Bissau, Liberia, Sierra-Leone, Gambia, Senegal, Mauritania, Western Sahara, Mali, Burkina Faso and Niger Republique. Apart from Nigeria, Senegal and Ghana all the other remaining' countries are extremely poor and unviable. As a result of this the sub-region has been experiencing a lot of civil unrest, countries like Liberia, Sierra Leon and Code Ivore have been experiencing civil wars since the early 1990s. In addition to the already existing problems of trafficking in drugs, arms, humans and weaponry trade within the sub-region. Today the sub-region is experiencing the coming of a new evil deal called 'Trade in radio active waste'; which involves the transporting Of radioactive wastes from the developed countries to it's waste bin in West Africa, where it is unsafely buried after collecting millions of dollars from It's original owners. Recent statistics have revealed that most of the people involved in the evil businesses of trafficking in drugs, human, arms and trading in weaponry, are diverting in to the so called evil business of 'Trade in Radioactive waste' because this new illegal trade financially exceeds the rest of the above listed evil businesses

    2012-07-01

    Using the Annenberg Perception of Tobacco Risk Survey 2, this paper finds that perceived risk deters smoking among persons aged 14-22 years who think that it is relatively difficult to quit smoking and that onset of deleterious health effects occurs relatively quickly. Perceived health risk, however, does not affect the smoking status of young people who hold the opposite beliefs. These results are consistent with predictions of rational addiction models and suggest that young people, who view smoking as more addictive and health effects as more immediate, may have greater incentive to consider long-term health effects in their decision to smoke.

    1987-01-01

    Some of the key findings are discussed of psychological research on the perception of risks and attitudes with respect to the use of uranium and coal for electricity generation. It appears that attitudes are mostly not based on ideology but rather determined by a trade-off of expected risks and advantages. Lay estimates of probabilities are compared with expert judgements. In the last section attitudes of people living near existing or planned power plants are analyzed. Serious doubts are raised about the possibilities to give residents economic compensation for exposure to risks. 1 fig., 29 refs.

    Background Patients at higher than average risk of heritable cancer may process risk information differently than the general population. However, little is known about clinical, demographic, or psychosocial predictors that may impact risk perception in these groups. The objective of this study was to characterize factors associated with perceived risk of developing cancer in groups at high risk for cancer based on genetics or family history. Methods We searched Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, and Scopus from inception through April 2009 for English-language, original investigations in humans using core concepts of "risk" and "cancer." We abstracted key information and then further restricted articles dealing with perceived risk of developing cancer due to inherited risk. Results Of 1028 titles identified, 53 articles met our criteria. Most (92%) used an observational design and focused on women (70%) with a family history of or contemplating genetic testing for breast cancer. Of the 53 studies, 36 focused on patients who had not had genetic testing for cancer risk, 17 included studies of patients who had undergone genetic testing for cancer risk. Family history of cancer, previous prophylactic tests and treatments, and younger age were associated with cancer risk perception. In addition, beliefs about the preventability and severity of cancer, personality factors such as "monitoring" personality, the ability to process numerical information, as well as distress/worry also were associated with cancer risk perception. Few studies addressed non-breast cancer or risk perception in specific demographic groups (e.g. elderly or minority groups) and few employed theory-driven analytic strategies to decipher interrelationships of factors. Conclusions Several factors influence cancer risk perception in patients at elevated risk for cancer. The science of characterizing and improving risk perception in cancer for high risk groups, although evolving, is still

    Siting of radioactive waste management facilities frequently raise arguments among stakeholders such as a municipal government and the residents. Risk communication is one of the useful methods of promoting mutual understanding on related risks among stakeholders. In Finland and Sweden, siting selection procedures of repositories for spent nuclear fuels have been carried out successfully with risk communication. The success reasons are analyzed based on the interviews with those who belong to the regulatory authorities and nuclear industries in both countries. Also, in this paper, risk communication among the Japan Radioisotope Association (JRIA), a local government and the general public, which was carried out during the establishment process of additional radioactive waste treatment facilities in Takizawa Village, Iwate Prefecture, is analyzed based on articles in newspapers and interviews with persons concerned. The analysis results showed that good risk communication was not carried out because of the lack of confidence on the JRIA, decision making rules, enough communication chances and economic benefits. In order to make good use of these experiences for the future establishment of radioactive waste management facilities, the lessons learned from these cases are summarized and proposals for good risk communication (establishment of exploratory committee and technical support system for decision making, and measurements to increase familiarity of radioactive waste) are discussed.

    2010-01-01

    This paper analyses some potential security risks, concerning terrorism or more mundane forms of crime, such as fraud, in management of nuclear waste using a PEST scan (of political, economic, social and technical issues) and some insights of criminologists on crime prevention. Nuclear waste arises as spent fuel from ongoing energy generation or other nuclear operations, operational contamination or emissions, and decommissioning of obsolescent facilities. In international and EU political contexts, nuclear waste management is a sensitive issue, regulated specifically as part of the nuclear industry as well as in terms of hazardous waste policies. The industry involves state, commercial and mixed public-private bodies. The social and cultural dimensions--risk, uncertainty, and future generations--resonate more deeply here than in any other aspect of waste management. The paper argues that certain tendencies in regulation of the industry, claimed to be justified on security grounds, are decreasing transparency and veracity of reporting, opening up invisible spaces for management frauds, and in doing allowing a culture of impunity in which more serious criminal or terrorist risks could arise. What is needed is analysis of this 'exceptional' industry in terms of the normal cannons of risk assessment - a task that this paper begins. Copyright 2009 Elsevier Ltd. All rights reserved.

    Full Text Available Health care or biomedical waste, if not managed properly, can be of high risk to the hospital staff, the patients, the community, public health and the environment, especially in low and middle income settings where proper disposal norms are often not followed. Our aim was to explore perceptions of staff of an Indian rural tertiary care teaching hospital on hospital waste management.A qualitative study was conducted using 10 focus group discussions (FGDs, with different professional groups, cleaning staff, nurses, medical students, doctors and administrators. The FGD guide included the following topics: (i role of Health Care Waste Management (HCWM in prevention of health care associated infections, (ii awareness of and views about HCWM-related guidelines/legislation, (iii current HCWM practices, (iv perception and preparedness related to improvements of the current practices, and (v proper implementation of the available guidelines/legislation. The FGDs were recorded, transcribed verbatim, translated to English (when conducted in Hindi and analysed using content analysis.Two themes were identified: Theme (A, 'Challenges in integration of HCWM in organizational practice,' with the categories (I Awareness and views about HCWM, (II Organizational practices regarding HCWM, and (III Challenges in Implementation of HCWM; and Theme (B, 'Interventions to improve HCWM,' with three categories, (I Educational and motivational interventions, (II Organizational culture change, and (III Policy-related interventions.A gap between knowledge and actual practice regarding HCWM was highlighted in the perception of the hospital staff. The participants suggested organizational changes, training and monitoring to address this. The information generated is relevant not merely to the microsystem studied but to other institutions in similar settings.

    The Industry Degraded Core (IDCOR) Program was designed to develop a comprehensive, technically sound position on the issues related to potential accidents in light water reactors. One of the goals is to acquire knowledge and data so that a more realistic approach to the problem is possible. Some of the IDCOR tasks develop information in a Probabilistic Risk Assessment (PRA) framework. The PRA approach is structured upon reliability characteristics for individual components, such as pumps, valves and relays, which can be used to predict the frequency of system failures. System failure combinations can then be used to predict the probability of undesirable plant response to given initiating events. The IDCOR PRA tasks provide a significant amount of information related to the response of the plant to severe accidents. This information has been derived in a logical and consistent manner and so provides a coherent and rational basis for decision-making

    2004-02-01

    Public opposition to genetically modified (GM) food and crops is widely interpreted as the result of the public's misperception of the risks. With scientific assessment pointing to no unique risks from GM crops and foods, a strategy of accurate risk communication from trusted sources has been advocated. This is based on the assumption that the benefits of GM crops and foods are self-evident. Informed by the interpretation of some qualitative interviews with lay people, we use data from the Eurobarometer survey on biotechnology to explore the hypothesis that it is not so much the perception of risks as the absence of benefits that is the basis of the widespread rejection of GM foods and crops by the European public. Some respondents perceive both risks and benefits, and may be trading off these attributes along the lines of a rational choice model. However, for others, one attribute-benefit-appears to dominate their judgments: the lexicographic heuristic. For these respondents, their perception of risk is of limited importance in the formation of attitudes toward GM food and crops. The implication is that the absence of perceived benefits from GM foods and crops calls into question the relevance of risk communication strategies for bringing about change in public opinion.

    1993-01-01

    This study investigated risk perception, well-being, and organizational commitment among nuclear power plant personnel. The study group, 428 employees from a nuclear power plant, completed a questionnaire which included the same questions as those in previous surveys on risk perception of lay persons and industrial workers. Hazards at work were not seen as a sizable problem by nuclear power plant personnel. The study group estimated the safety of nuclear power plants better and the possibility of a serious nuclear accident as more unlikely than the general public. Compared to employees in other industrial companies, the overall perceived risks at work among plant personnel did not exceed the respective perceptions of the reference groups. Risk-related attitudes did not explain well-being among plant personnel, but the relationship between the perceived probability of a serious nuclear accident at work and organizational commitment yielded to a significant correlation: Those plant workers who estimated the likelihood of an accident higher were less committed to the organization. 21 refs., 2 tabs

    Unmanned aircraft, or drones, are a rapidly emerging sector of the aviation industry. There has been limited substantive research, however, into the public perception and acceptance of drones. This article presents the results from two surveys of the Australian public designed to investigate (1) whether the public perceive drones to be riskier than existing manned aviation, (2) whether the terminology used to describe the technology influences public perception, and (3) what the broader concerns are that may influence public acceptance of the technology. We find that the Australian public currently hold a relatively neutral attitude toward drones. Respondents did not consider the technology to be overly unsafe, risky, beneficial, or threatening. Drones are largely viewed as being of comparable risk to that of existing manned aviation. Furthermore, terminology had a minimal effect on the perception of the risks or acceptability of the technology. The neutral response is likely due to a lack of knowledge about the technology, which was also identified as the most prevalent public concern as opposed to the risks associated with its use. Privacy, military use, and misuse (e.g., terrorism) were also significant public concerns. The results suggest that society is yet to form an opinion of drones. As public knowledge increases, the current position is likely to change. Industry communication and media coverage will likely influence the ultimate position adopted by the public, which can be difficult to change once established. © 2014 Society for Risk Analysis.

  1. Risk perception, safety goals and regulatory decision-making

    Deciding on 'how safe is safe enough?' includes value judgements with implications of an ethical and political nature. As regulators are accountable to governments, parliaments and the general public, regulatory decision-making should be characterized by transparency with respect to how such value judgements are reflected in risk assessments and regulatory decisions. Some approaches in this respect are discussed in the paper, based on more than fifteen years of experience in nuclear regulatory decision-making. Issues discussed include: (1) risk profiles and safety goals associated with severe reactor accidents--individual health risks, societal risks and risk of losing investments; (2) risk profile-based licensing of the Swedish SFR final disposal facility for low and intermediate level radioactive waste

    A limited scope risk assessment was performed on the preliminary design of a high-level waste interim storage facility. The Canister Storage Building (CSB) facility will be built to support remediation at the US Department of Energy Hanford Site in Washington State. The CSB will be part of the support facilities for a high level Hanford Waste Vitrification Plant (HWVP). The limited scope risk assessment is based on a preliminary design which uses forced air circulation systems to move air through the building vault. The current building design calls for natural circulation to move air through the building vault

    Using the instruments of the empirical social sciences, a cross-section study was conducted comprising experiments on qualitative risk characteristics, in-depth interviews on mechanisms of risk perception and representative surveys of the public on technical risk sources, in particular with regard to nuclear energy. The results of these studies show that person-related expectations in respect of risk consequences, the possibility of personal influencing control, the severity of risk consequences and one's own risk propensity play a significant role in the evaluation of risks

    1978-01-01

    Within the scope of a system study, ''Radioactive wastes in the Federal Republic of Germany,'' performed from 1974 through 1976, the questions of risk assessment were investigated. A risk analysis of a high-level waste (HLW) management system was performed. The results of the HLW tank storage are that the risk expectation value is 700 nJ/kg x RBE (7 x 10 -5 rem) per year for atmospheric release. The discussion of the main contributing accidents shows the possibility of reducing the risk by a technical means. A qualitative comparison on the release basis with the results of the WASH-1400 report shows significant differences that can be explained by the different methodologies applied. The risk analysis activities have led to a comprehensive risk assessment project, which was recently started. The projected includes research and development tasks concerning nuclide migration and transport to the ecosphere, nuclide mobilization by various mechanisms, methodology problems, data collection, computer code development, as well as risk analyses of waste management facilities. It is intended to round off the project with risk analyses of spent fuel element transport, storage, and reprocessing

    The prioritization of solid waste disposal options in terms of reduced risk to workers, the public, and the environment has recently generated considerable governmental and public interest. In this paper we address the development of a methodology to establish priorities for waste disposal options, such as incineration, landfills, long-term storage, waste minimization, etc. The study is one result of an overall project to develop methodologies for Probabilistic Risk Assessments (PRAs) of non-reactor nuclear facilities for the US Department of Energy. Option preferences are based on a levelized cost-risk reduction analysis. Option rankings are developed as functions of disposal option cost and timing, relative long- and short-term risks, and possible accident scenarios. We examine the annual costs and risks for each option over a large number of years. Risk, in this paper, is defined in terms of annual fatalities (both prompt and long-term) and environmental restoration costs that might result from either an accidental release or long-term exposure to both plant workers and the public near the site or facility. We use event timing to weigh both costs and risks; near-term costs and risks are discounted less than future expenditures and fatalities. This technique levels the timing of cash flows and benefits by converting future costs and benefits to present value costs and benefits. We give an example Levelized Cost-Benefit Analysis of incinerator location options to demonstrate the methodology and required data

    The final destination of the waste generated in a nuclear power plant remains a big challenge. The question is not only the radiation emitted by the sources, in some cases for many years, but also the public acceptance of this theme. In many countries where a nuclear waste storage facility has to be built, the local population of the chosen site did not accept it at first, and the whole process had to restart including this variable. In the past, the population opinion was considered not relevant but several international experiences showed that in fact it can not be forgotten. Statistical data show that a significant fraction of the population of the world has many concerns about nuclear energy and its potential impacts. Although many experts state that it has environmental advantages, such as the absence of greenhouse gases emissions, the subject is still the target of never ending discussions. But it is a concrete fact that the sector is growing in many countries. The objective of this article is to summarize several experiences in many countries associated with nuclear energy, mainly those ones that involve nuclear storage facilities, and its acceptance by the public. This task can help CNEN in the studies associated with the RMBN project - Repository for Radioactive Waste with Low and Medium Levels of Radiation. (author)

    Health effects and risks of radiation and radionuclides are being misunderstood by many members of general public. Many peoples have fear and anxieties for radiation. So far, the health effects from radiation at low dose and low dose rate have not been cleared on biological aspects. Then, we have quantitatively estimated health risks of low-dose radiation on the basis of linear dose response relationship without threshold from the viewpoints of radiation protection by using both epidemiological data, such as atomic bomb survivors, and some models and assumptions. It is important for researchers and relevant persons in radiation protection to understand the process of risk estimation of radiation and to communicate an exact knowledge of radiation risks of the public members.

    Introduction Disasters will continue to occur throughout the world and it is the responsibility of the government, health care systems, and communities to adequately prepare for potential catastrophic scenarios. Unfortunately, low-and-middle-income countries (LMICs) are especially vulnerable following a disaster. By understanding disaster preparedness and risk perception, interventions can be developed to improve community preparedness and avoid unnecessary mortality and morbidity following a natural disaster. Problem The purpose of this study was to assess disaster preparedness and risk perception in communities surrounding Trujillo, Peru. After designing a novel disaster preparedness and risk perception survey based on guidelines from the International Federation of Red Cross and Red Crescent Societies (IFRC; Geneva, Switzerland), investigators performed a cross-sectional survey of potentially vulnerable communities surrounding Trujillo, Peru. Data were entered and analyzed utilizing the Research Electronic Data Capture (REDCap; Harvard Catalyst; Boston, Massachusetts USA) database. A total of 230 study participants were surveyed, composed of 37% males, 63% females, with ages ranging from 18-85 years old. Those surveyed who had previously experienced a disaster (41%) had a higher perception of future disaster occurrence and potential disaster impact on their community. Overall, the study participants consistently perceived that earthquakes and infection had the highest potential impact of all disasters. Twenty-six percent of participants had an emergency supply of food, 24% had an emergency water plan, 24% had a first aid kit at home, and only 20% of the study participants had an established family evacuation plan. Natural and man-made disasters will remain a threat to the safety and health of communities in all parts of the world, especially within vulnerable communities in LMICs; however, little research has been done to identify disaster perception

    Results from 4 studies are reported. A mixture of survey, experimental and quasi-experimental designs and a variety of samples (undergraduates, postgraduates and graduates of Nottingham University, visitors to Sellafield and a random national UK sample) were used to examine risk perceptions of nuclear energy. The roles of risk, benefit, preference, knowledge, control, trust, attitudes, intentions to act and personality, in relation to nuclear energy, were examined. A survey study examined and explored the above-mentioned variables. Then experimental and quasi-experimental studies were devised using a BNFL video advert, a BNFL written newspaper advert and BNFL's Sellafield Visitors' Centre (SVC), to test the effectiveness of information on these variables. Through pre-post experimental and quasi-experimental studies, it was shown that levels of knowledge could be increased through information. This increase was also seen to be sustained over time, especially when people engaged in their learning environment (reading a newspaper or going to Sellafield). Regarding levels of knowledge, passively watching a video had a significant but very small effect. Changes in attitudes were also recorded, although these were only sustained over time for the Visitors' Centre. Concerning the other variables in question, changes in perceived risk, perceived benefit and preference were also recorded for the samples, although these results either could not be attributed to the different types of information, were not sustained or were no different to observations in the control groups. Some changes were recorded for aspects of control in the advert study although none were seen in the SVC study. No changes were found in trust for any of the different types of information. The main, consistent finding, was that sustained changes were recorded for knowledge and attitudes. These were both found to be linked to many of the variables under investigation, including risk

    Over the last few decades, Europe has suffered from a number of severe flood events and, as a result, there has been a growing interest in probing alternative approaches to managing flood risk via prevention measures. A literature review reveals that, although in the last decades risk evaluation has been recognized as key element of risk management, and risk assessment methodologies (including risk analysis and evaluation) have been improved by including social, economic, cultural, historical and political conditions, the theoretical schemes are not yet applied in practice. One main reason for this shortcoming is that risk perception literature is mainly of universal and theoretical nature and cannot provide the necessary details to implement a comprehensive risk evaluation. This paper therefore aims to explore a procedure that allows the inclusion of stakeholders' perceptions of prevention measures in risk assessment. It proposes to adopt methods of risk communication (both one-way and two-way communication) in risk assessment with the final aim of making flood risk management more effective. The proposed procedure not only focuses on the effect of discursive risk communication on risk perception, and on achieving a shared assessment of the prevention alternatives, but also considers the effects of the communication process on perceived uncertainties, accepted risk levels, and trust in the managing institutions. The effectiveness of this combined procedure has been studied and illustrated using the example of the participatory flood prevention assessment process on the Sihl River in Zurich, Switzerland. The main findings of the case study suggest that the proposed procedure performed well, but that it needs some adaptations for it to be applicable in different contexts and to allow a (semi-) quantitative estimation of risk perception to be used as an indicator of adaptive capacity.

    The Buried Waste Integrated Demonstration is supporting the development, demonstration, testing, and evaluation of a suite of technologies that, when integrated with commercially available technologies, form a comprehensive system for the remediation of radioactive and hazardous buried waste. As a part of the program's technology development, remote retrieval equipment is being developed and tested for the remediation of buried waste. During remedial planning, several factors are considered when choosing remote versus manual retrieval systems. Time that workers are exposed to radioactivity, chemicals, air particulate, and industrial hazards is one consideration. The generation of secondary waste is also a consideration because it amounts to more waste to treat and some wastes may require special handling or treatment. Cost is also a big factor in determining whether remote or manual operations will be used. Other considerations include implementability, effectiveness, and the number of required personnel. This paper investigates each of these areas to show the risk and cost benefits and limitations for remote versus manual retrieval of buried waste

    This study analyzes effects of changes in risk perceptions of smoking's health harms on actual and attempted quits and quitting intentions of male smokers in China. Our survey of 5000+ male smokers was conducted two years after their neighbor's lung cancer diagnosis. We use proximity to a lung cancer neighbor as an exogenous determinant of individual's smoking risk perception. We show that learning of a neighbor's lung cancer diagnosis substantially affects smokers' subjective beliefs about smoking's harms, which in turn affects decisions about continued smoking and intentions to quit. Our study findings offer important public policy implications in indicating the importance of designing health-warning messages that fit smokers' personal circumstances as opposed to warnings solely based on edicts from scientific experts and/or epidemiological evidence.

    Full Text Available The aim of this paper is to isolate the corporate reputational risk faced by US oil and gas companies—as listed on the New York Stock Exchange (NYSE—after recent oil spill disasters. For this purpose, we have conducted a standard short-horizon daily event study analysis aimed at the calibration of the financial perceptions caused by these environmental episodes between 2005 and 2011, and the drop effect on the market value of the firms analyzed. We not only find significant negative impact on the stock prices of the companies analyzed but also significant cumulative negative abnormal returns (CAR around the accidental spillages, especially for the longest event windows. Corporate reputational risk is also identified and even measured by adjusting abnormal returns by a certain loss ratio. A new metric, CAR(Rep, is then proposed to disentangle operational losses and the reputational damage derived from such negative financial perceptions.

    The purpose of this study is to analyze the characteristics of risk perception associated with nuclear power plants in the framework of the behavioral economics, such as prospect theory. Due to the bounded rationality of the people, the public tends to overestimate the risk of nuclear power, especially after the disaster of Fukushima Daiichi in Japan. Social acceptance is an essential element for the nuclear power plants, but nuclear option is getting regarded as a risky choice. On the other hand, experts define and measure risk by the calculation of the probability of damage to the core as a result of sequences of accidents identified by the study. However, this approach also involves limitations to some extent. We explore a possible way to close the gap under in the by wider social context with consideration of risk trade-off among various risk factors, rather than focusing only on nuclear issue. (author)

    This study aimed to determine the effect that level of concern for osteoporosis, as well as self-perceived risk of osteoporosis and fracture, has on supplementation use, seeking medical advice, bone mineral density (BMD) testing, and antiosteoporosis medication (AOM) use. Study subjects were 1,095 female Australian participants of the Global Longitudinal study of Osteoporosis in Women (GLOW) untreated for osteoporosis at baseline. Study outcomes from self-administered questionnaires included calcium and vitamin D supplementation, self-reported seeking of medical advice regarding osteoporosis, BMD testing, and AOM use in the last 12 months at the late assessment. Logistic regression was used in the analysis. Concern significantly increased the likelihood of seeking medical advice and, however, had no significant impact on screening or treatment. Heightened self-perceived risks of osteoporosis and fracture both significantly increased the likelihood of seeking medical advice and BMD testing while elevated self-perceived risk of fracture increased AOM use. Supplementation use was not significantly associated with concern levels and risk perception. Concern and risk perceptions to osteoporosis and fracture were significantly associated with certain bone-protective behaviours. However, the disconnect between perceived osteoporosis risk and AOM use illustrates the need to emphasize the connection between osteoporosis and fracture in future education programs. PMID:25276471

    For effective risk communication, clinicians must understand patients' values and beliefs in relation to the risks of treatment. This qualitative study aimed to explore adolescent perceptions of orthodontic treatment risks and risk information. Five focus groups were carried out with 32 school/college pupils aged 12-18 in Wales, UK. Participants were purposively selected and had all experienced orthodontic treatment. A thematic approach was used for analysis and data collection was completed at the point of data saturation. Four themes emerged from the data; (a) day-to-day risks of orthodontic treatment, (b) important orthodontic risk information, (c) engaging with orthodontic risk information and (d) managing the risks of orthodontic treatment. Day-to-day risks of orthodontic treatment that were affecting participants "here and now" were of most concern. Information about preventing the risks of treatment was deemed to be important. Participants did not actively seek risk information but engaged passively with information from convenient sources. Perceptions of risk susceptibility influenced participants' management of the risks of orthodontic treatment. This study demonstrates that adolescent patients can understand information about the nature and severity of orthodontic treatment risks. However, adolescent patients can have false perceptions if the risks are unfamiliar, perceived only to have a future impact or if seen as easy to control. Adolescent patients must be provided with timely and easily accessible risk information and with practical solutions to prevent the risks of treatment. The views and experiences gathered in this study can assist clinicians to better understand their young patients' beliefs about treatment risks, facilitate effective risk communication and contribute to improved patient-centred care.

    1980-01-01

    The problems of risk analysis of geological disposal of radioactive waste are briefly summarized. Several characteristics, such as the very long time span considered, make it rather unique among the problems of modern society. The safety of nuclear waste disposal in geological formations is based on several barriers, natural and man-made, which prevent disposed radionuclides from reaching the biosphere. They include a) the physico-chemical form of conditioned waste, b) the waste container, c) the geological isolation, d) buffering and backfilling materials, radionuclide retention in the geosphere and e) environmental dilution and isolation processes. The knowledge available on each barrier and its modelling is reviewed. Specific disposal strategies in clay, granite and salt formations are considered, outlining the performance of the barriers in each particular strategy, and results obtained in preliminary evaluations

    Full Text Available The turn of the century has brought a lot of radical shifts and risks for tourism industry, which ranged from terrorism to lethal virus outbreaks. Henceforth risk perception theory, which was formulated in psychology, was re-appropriated by policy makers and tourism-related scholars. However, from its inception this conceptual corpus was based on the economic-centred paradigm. This piece discusses critically the main limitations of risk perception theory and the rise of a new discipline, post disaster marketing, in view of the caveats and speculative assumption of “the precautionary principle”.

  2. The Perception Gap: Recognizing and managing the risks that arise when we get risk wrong.

    Science.gov (United States)

    Ropeik, David

    2012-05-01

    Many in the academic, science, and business communities are frustrated at how people perceive and respond to risk, lamenting that the lay public is sometimes more afraid of some threats than the evidence warrants, and less afraid of some dangers than the evidence warns. This is often ascribed to the alarmist way the news media cover risk-related subjects. That criticism is simplistic and unproductive, and ignores or dismisses the large body of research that finds that the perception of risk is not, and can never be, perfectly rational. Risk perception among members of the public, the media, and members of the academic, scientific, and business communities, is ultimately subjective. The gap between our fears and the evidence is not simply the product of alarmist media reporting. This 'Perception Gap' poses significant risks in and of itself, influencing the choices we make as individuals and as a society. The roots of the Perception Gap must be understood if we are to recognize the dangers that can arise when we sometimes get risk wrong, and in order that we may more wisely manage those risks as actively as we manage toxicological or food or other risks with which we are more familiar.

    1982-01-01

    This paper describes the recent work of the authors on the evaluation of health risk benefits of space disposal of nuclear waste. The paper describes a risk model approach that has been developed to estimate the non-recoverable, cumulative, expected radionuclide release to the earth's biosphere for different options of nuclear waste disposal in space. Risk estimates for the disposal of nuclear waste in a mined geologic repository and the short- and long-term risk estimates for space disposal were developed. The results showed that the preliminary estimates of space disposal risks are low, even with the estimated uncertainty bounds. If calculated release risks for mined geologic repositories remain as low as given by the U.S. DOE, and U.S. EPA requirements continue to be met, then no additional space disposal study effort in the U.S. is warranted at this time. If risks perceived by the public are significant in the acceptance of mined geologic repositories, then consideration of space disposal as a complement to the mined geologic repository is warranted.

    The acceptable level of radiation risk for public members, that is 10/sup -5//y, was proposed by ICRP and other international organizations. We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10/sup -5//y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure. From these bases we derived the value of 10/sup -5//y as acceptable risk level in Japan. The perception to risk level of 10/sup -5//y in conventional life was investigated by means of questionnaires for 1,095 college students living in Tokyo. The risks considered in this study were natural background radiation, coffee, skiing, X-ray diagnosis, spontaneous cancer, passive smoking and air pollution. The most acceptable risk was the risk related with natural background radiation. And the risk of natural background radiation was more easily accepted by the students who had knowledges on natural background radiation. On the other hand, the risk from air pollution or passive smoking was the most adverse one.

    The acceptable level of radiation risk for public members, that is 10 -5 /y, was proposed by ICRP and other international organizations. We studied to survey basic procedures of deriving this value and to derive an acceptable risk value in Japan by using similar procedures. The basic procedures to derive 10 -5 /y were found as follows; (1) 0.1 percent of annual mortality from all diseases, (2) 0.1 percent of life time risk, (3) one percent of mortality from all causes in each age cohort and (4) corresponding value to 1 mSv annual radiation exposure.

    To examine change in risk perception and optimistic bias concerning behavior-linked health threats and environmental health threats between adolescence and young adulthood and how these factors related to personal satisfaction. In 1996 and 2002, 1624 adolescents responded to a mailed questionnaire. Adolescents showed strong positive optimistic bias concerning behaviorlinked risks, and this optimistic bias increased with age. Increase in optimistic bias over time predicted increase in personal satisfaction. The capacity to process and perceive potential threats in a positive manner might be a valuable human ability positively influencing personal satisfaction and well-being.

    Risk analysis tools have been successfully used to determine the potential hazard associated with disease introductions and have facilitated management decisions designed to limit the potential for disease introduction. Chronic Wasting Disease (CWD) poses significant challenges for resource managers due to an incomplete understanding of disease etiology and epidemiology and the complexity of management and political jurisdictions. Tools designed specifically to assess the risk of CWD introduction would be of great value to policy makers in areas where CWD has not been detected.

    In recent years, perception of flood risks has become an important topic to policy makers concerned with risk management and safety issues. Knowledge of the public risk perception is considered a crucial aspect in modern flood risk management as it steers the development of effective and efficient flood mitigation strategies. This study aimed at gaining insight into the perception of flood risks along the Belgian coast. Given the importance of the tourism industry on the Belgian coast, the survey considered both inhabitants and residential tourists. Based on actual expert's risk assessments, a high and a low risk area were selected for the study. Risk perception was assessed on the basis of scaled items regarding storm surges and coastal flood risks. In addition, various personal and residence characteristics were measured. Using multiple regression analysis, risk perception was found to be primarily influenced by actual flood risk estimates, age, gender, and experience with previous flood hazards. © 2011 Society for Risk Analysis.

  17. Affect-Laden Imagery and Risk Taking: The Mediating Role of Stress and Risk Perception

    Science.gov (United States)

    2015-01-01

    This paper investigates how affect-laden imagery that evokes emotional stress influences risk perception and risk taking in real-life scenarios. In a series of three studies, we instructed participants to imagine the consequences of risky scenarios and then rate the intensity of the experienced stress, perceived risk and their willingness to engage in risky behavior. Study 1 showed that people spontaneously imagine negative rather than positive risk consequences, which are directly related to their lower willingness to take risk. Moreover, this relationship was mediated by feelings of stress and risk perception. Study 2 replicated and extended these findings by showing that imagining negative risk consequences evokes psychophysiological stress responses observed in elevated blood pressure. Finally, in Study 3, we once again demonstrated that a higher intensity of mental images of negative risk consequences, as measured by enhanced brain activity in the parieto-occipital lobes, leads to a lower propensity to take risk. Furthermore, individual differences in creating vivid and intense negative images of risk consequences moderated the strength of the relationship between risk perception and risk taking. Participants who created more vivid and intense images of negative risk consequences paid less attention to the assessments of riskiness in rating their likelihood to take risk. To summarize, we showed that feelings of emotional stress and perceived riskiness mediate the relationship between mental imagery and risk taking, whereas individual differences in abilities to create vivid mental images may influence the degree to which more cognitive risk assessments are used in the risk-taking process.

    Although urban community gardening can offer health, social, environmental, and economic benefits, these benefits must be weighed against the potential health risks stemming from exposure to contaminants such as heavy metals and organic chemicals that may be present in urban soils. Individuals who garden at or eat food grown in contaminated urban garden sites may be at risk of exposure to such contaminants. Gardeners may be unaware of these risks and how to manage them. We used a mixed quantitative/qualitative research approach to characterize urban community gardeners' knowledge and perceptions of risks related to soil contaminant exposure. We conducted surveys with 70 gardeners from 15 community gardens in Baltimore, Maryland, and semi-structured interviews with 18 key informants knowledgeable about community gardening and soil contamination in Baltimore. We identified a range of factors, challenges, and needs related to Baltimore community gardeners' perceptions of risk related to soil contamination, including low levels of concern and inconsistent levels of knowledge about heavy metal and organic chemical contaminants, barriers to investigating a garden site's history and conducting soil tests, limited knowledge of best practices for reducing exposure, and a need for clear and concise information on how best to prevent and manage soil contamination. Key informants discussed various strategies for developing and disseminating educational materials to gardeners. For some challenges, such as barriers to conducting site history and soil tests, some informants recommended city-wide interventions that bypass the need for gardener knowledge altogether.

    Nuclear energy was becoming increasingly popular as an alternative to air polluting fossil fuel technologies through the latter half of the 2000s. The tragic events of March 11, 2011 in Fukushima, Japan appear to have instantly killed any momentum the nuclear industry had gained. While unfortunate, many argue that nuclear power is still a safe alternative and that the Fukushima disaster resulted from insufficient safety regulations in Japan, a problem that does not exist in the United States. This project examines U.S. public support for nuclear energy one year after the Fukushima tragedy, seeking to understand the influence of knowledge and risk perceptions on policy support. We evaluate public support for nuclear energy policy from several perspectives using risk and attitudinal measurements that are more specific than often found in the literature to obtain a greater understanding of the connection between policy and risk. -- Highlights: •Paper evaluates US public support for nuclear energy1 year after Fukushima tragedy. •Attitudinal indicators are significant predictors of nuclear power policy support. •People more knowledgeable about energy issues are more supportive of nuclear energy. •Perceptions of risk exert varying influence on support for nuclear power. •Specific attitude and risk indicators permit nuanced insight into their influence

    Full Text Available Risk stratification (RS in primary care is frequently used by policy-makers, payers, and health systems; the process requires risk assessment for adverse health outcomes across a population to assign patients into risk tiers and allow care management (CM resources to be targeted effectively. Our objective was to understand the approach to and perception of RS in primary care practices. An online survey was developed, tested, and administered to 148 representatives of 37 primary care practices engaged in RS varying in size, location and ownership. The survey assessed practices’ approach to, perception of, and confidence in RS, and its effect on subsequent CM activities. We examined psychometric properties of the survey to determine validity and conducted chi-square analyses to determine the association between practice characteristics and confidence and agreement with risk scores. The survey yielded a 68% response rate (100 respondents. Overall, participants felt moderately confident in their risk scores (range 41–53.8%, and moderately to highly confident in their subsequent CM workflows (range 46–68%. Respondents from small and independent practices were more likely to have higher confidence and agreement with their RS approaches and scores (p < 0.01. Confidence levels were highest, however, when practices incorporated human review into their RS processes (p < 0.05. This trend was not affected by respondents’ professional roles. Additional work from a broad mixed-methods effort will add to our understanding of RS implementation processes and outcomes.

    As it is well known, an accident with a teletherapy source made of 137 CsCl with an initial activity of 59 TBq occurred in Goiania, in September of 1987. This paper will discuss the decision-making process, and the struggle that followed the decision to build the final repository for the remnants of the Goiania accident. The Goiania final repository was built as planned. The two subsurface structures under the grassy artificial hills hold the overall volume of the remnants of the Goiania accident. The near hill holds 5x10 3 m3 of stabilized wastes without radioactivity, or with very low radioactivity. The far hill holds the remaining 6.5x10 3 m 3 of stabilized wastes with low and medium radioactivity. The central part of each subsurface hill has been shielded by wastes with less and less radioactivity. The overall fenced area occupies 1.85x10 5 m 2 . The external radiation levels are similar to the surrounding background, and much lower than those found in the Brazilian areas of high natural radioactivity. The site is permanently monitored by independent institutions, including Brazilian universities, and national and international organizations. As it was mentioned earlier, the final repository was build to last for at least 400 years. Although the initial decision to adopt a too conservative decontamination criterion in the case of the Goiania accident was bound to produce excessive amount of waste; such decision proved, retrospectively, not to be bad because the excess low radioactive waste produced was used as extra shielding material in final repository. The technical decision-maker should not abandon risk estimates, but should be aware that credibility is the main basis to achieve acceptability of a decision by the general public. Risk perception should be regarded as only a first step towards what may be called knowledge, or comprehension of risk estimates, but risk perception by the general public is still an open issue.

    Municipal solid waste (MSW) piling up is becoming a serious problem in all developing countries (DC) as a result of inequitable waste collection and treatment. Citizens' collaboration is partly based on understanding their views and their active involvement in MSW planning; on the other hand the assessment of the perception of hazardousness related with MSW is considered rather important as well since the identification of the weak points of the applied MWM strategy is eased and the level of required training is determined. Researchers implemented a case study in the West Bank (WB) and Gaza Strip (GS) regions of Palestine, taking into consideration previous researches in other developing countries. They reached to safe and useful conclusions regarding the parameters which mean the greatest in the waste management field as far as DC are concerned. Lack of skilled manpower, irregular collection services, inadequate equipment used for waste collection, inadequate legal provisions, and resource constraints are additional factors that are confirmed to be challenging the waste management scenarios in all DCs today. The research takes those factors under consideration but focuses on the educational gap and the results revealed interesting trends a significant relationship between respondent's educational attainment and their awareness of hazardous waste (hazard perception); the results will indicate the measure taking required to avoid accidents occurred in those regions (burns from toxics, cuts from sharps, etc). National policy and legislation development based on the research outcomes will ensure equitable and accessible services are in place in order to move towards a healthier environment. Specialized health education and training programs on national scale are also needed to enhance awareness on hazardous waste. Copyright © 2014 Elsevier Ltd. All rights reserved.

  5. Development of risk assessment methodology applicable to radioactive waste isolation

    1978-01-01

    The risk from radioactive waste disposal in a deep geologic formation has not yet been completely assessed. A complete assessment should include credible estimates of the likelihood that radioactive materials would escape the repository and enter the human environment, and the magnitude of the resultant consequences in terms of human health effects. In addition, such an assessment should identify the dominant contributors to risk and, to the extent possible, quantify the uncertainties in risk estimates. A complete risk assessment may not be possible because of our limited knowledge of various aspects of geology and hydrogeology important to the long-term safety of a radioactive waste repository. The results of past analyses are not entirely consistent, perhaps as a direct result of the limited knowledge of the phenomena involved. It may, therefore, seem premature to attempt a rigorous risk analysis of radioactive waste disposal in deep, geologic media at the present time. However, the value of such analyses lies more in the insight and information they provide than in their prediction of absolute levels of risk

    Smith, C.F.

    1975-01-01

    The risks associated with the disposal of high level wastes derive from the potential for release of radioactive materials into the environment. The assessment of these risks requires a methodology for risk analysis, an identification of the radioactive sources, and a method by which to express the relative hazard of the various radionuclides that comprise the high level waste. The development of a methodology for risk analysis is carried out after a review of previous work in the area of probabilistic risk assessment. The methodology suggested involves the probabilistic analysis of a general accident consequence distribution. In this analysis, the frequency aspect of the distribution is treated separately from the normalized probability function. At the final stage of the analysis, the frequency and probability characteristics of the distribution are recombined to provide an estimate of the risk. The characterization of the radioactive source term is accomplished using the ORIGEN computer code. Calculations are carried out for various reactor types and fuel cycles, and the overall waste hazard for a projected thirty-five year nuclear power program is determined

    We report data from the first representative national phone survey of Americans' perceptions about nanotechnology (N =1536). Public opinion about nanotechnology is in its infancy, and knowledge about it is quite limited. Yet, Americans' initial reaction to nanotechnology is thus far generally positive, probably rooted in a generally positive view of science overall. Survey respondents expected benefits of nanotechnology to be more prevalent than risks, and they reported feeling hopeful about nanotechnology rather than worried. Their most preferred potential benefit of nanotechnology is 'new and better ways to detect and treat human diseases,' and they identified 'losing personal privacy to tiny new surveillance devices' as the most important potential risk to avoid. The most discouraging aspect to the data is respondents' lack of trust in business leaders to minimize nanotechnology risks to human health. Overall, these data indicate that while Americans do not necessarily presume benefits and the absence of risks, their outlook is much more positive than not

    The measurement of the risk-related impacts from the siting of a high-level nuclear waste (HLNW) repository represents a new and important addition to conventional socioeconomic impact studies. In particular, the driving forces behind these impacts are the risks people perceive to be associated with the repository. Measuring the risk impacts requires a complementary set of approaches, of which, risk surveys are the cornerstone.a The purpose of these surveys is to provide scientifically defensible measures of the risk-related impacts. The risk surveys follow directly from a conceptual framework of how the HLNW repository affects peoples' perceptions and, ultimately, their behaviors. These surveys describe and measure: Characteristics of individuals, Risks people perceive from the HLNW repository, Views, or mind sets, they form about the HLNW repository, Changes in behaviors--e.g., changes in retirement decisions or industrial relocations--induced by the location of the repository, and Changes in well-being of Nevada citizens, if the repository were located at Yucca Mountain

    A new research project has started to develop two kinds of on-the-web communication systems which are aimed at effective social risk information on nuclear energy. One is mutual communication system for fostering safety culture among the workers in nuclear industry while the other is to enlighten general public about the risk issues on final disposal of high-level radioactive waste. Prior to the on-the-web systems development, social investigations have been conducted on risk perception for nuclear power for both the nuclear experts and women in the metropolitan area, in order to know how and what should be considered for the effective risk communication methods. It was found from the statistical analysis of the results of social investigation that the majority of nuclear people take business risk seriously but there is a fraction of nuclear people who are afraid of present practice of nuclear power operation while women in metropolitan area are evenly afraid of radioactive risk. The obtained results of social investigation gave useful insight for developing two kinds of risk communication systems and the related field study for enhancing safety culture in nuclear industries.

For such a subtle task, it will be good to know something about the person, who undertakes such a challenge. Thus, he first makes a short description of himself in a number of relevant personal feature, emphasising rather what he is not: cadre of insurance company.... etc. He starts with a literal understanding of the idiom Risk Perception in English and in other languages (in Chinese). This formulation, still abstract, is framed with concrete objects, and materialised into touchable structures. He then puts life into these structures, and makes them accessible to emotion and experience. Now that this notion is animated, he follows it's way into life in the field of Radiation Protection, and find among others that the term Cost and Benefit correspond to the Chinese idiom, and that the system of Justification and Optimisation is as difficult to achieve objectively as an Upright Walk on the Confucian Path to-ward the Middle. One of the difficulties lies in the difference in the scale in estimating values.

This leads, according to the author, to the well known and accepted term of Risk Residuum, in German, Rest Risiko. Despite of partialness of all perceptions, solid decisions are based on perception.

    This GFSI Risk Management Plan (RMP) describes the strategy for assessing and managing project risks for the Integrated Waste Treatment Unit (IWTU) that are specifically within the control and purview of the U.S. Department of Energy (DOE), and identifies the risks that formed the basis for the DOE contingency included in the performance baseline. DOE-held contingency is required to cover cost and schedule impacts of DOE activities. Prior to approval of the performance baseline (Critical Decision-2) project cost contingency was evaluated during a joint meeting of the Contractor Management Team and the Integrated Project Team for both contractor and DOE risks to schedule and cost. At that time, the contractor cost and schedule risk value was $41.3M and the DOE cost and schedule risk contingency value is $39.0M. The contractor cost and schedule risk value of $41.3M was retained in the performance baseline as the contractor's management reserve for risk contingency. The DOE cost and schedule risk value of $39.0M has been retained in the performance baseline as the DOE Contingency. The performance baseline for the project was approved in December 2006 (Garman 2006). The project will continue to manage to the performance baseline and change control thresholds identified in PLN-1963, ''Idaho Cleanup Project Sodium-Bearing Waste Treatment Project Execution Plan'' (PEP)

    A significant problem in radioactive waste facility siting is that apparent small risks or minor risks events produce substantial public concern and social impacts. The reasons for this difference in public health and societal impacts is not well understood. This paper explores the issues involved in the social amplification of risk, using the risk associated with site characterization as the example. Noteworthy as sources of amplification are the information flow associated with risks and risk events including the large volume of information, the extent of dispute, and misinformation and rumor. Such information passes through the mass media and interpersonal networks. The major mechanisms involved in risk amplifications are discussed and their likely impacts on society described

    It has long been recognized in the nuclear industries and the regulatory body that exemption from the regulatory control for a given practice or source of radioactive materials, which is very low radiation exposure situation where the level of risk to any of the public would be considered as trivial, may be beneficial and practical. Therefore, it is necessary to establish the exempt levels of radioactive wastes for unconditional disposal, incineration, recycle and reuse of slightly contaminated materials. In Korea, from its announcement of the Enforcement Regulation of Atomic Energy Act, the Article 97 (Exemption from Permanent Disposal) for very low-level waste disposal in January 1990, the KINS (Korea Institute of Nuclear Safety) have made their efforts to establish a de minimis level (a level of radioactivity in waste that is sufficiently low that the waste can be disposed of as ordinary, non-radioactive trash) for short-lived radioisotopes commonly used in medical, research institutes and industrial applications and to study the possibility for unrestricted deregulation of those radioisotopes. As one of preliminary works to predict environmental radiological impacts from uncontrolled and unrestricted release of RI waste, an average effective dose to any ordinary individual and a collective dose for total population in Korea was estimated, based on conservative assumptions and Korean specific environment data, by an equilibrium biosphere models with a generic probabilistic risk approach

    This work begins with exposition of the basics of risk analysis. These basics are then applied to the Finnish radioactive waste disposal environment in which the nuclear power companies are responsible for all costs of radioactive waste management including longterm disposal of spent fuel. Nuclear power companies prepare cost estimates of the waste disposal on a yearly basis to support the decision making on accumulation of resources to the nuclear waste disposal fund. These cost estimates are based on the cost level of the ongoing year. A Monte Carlo simulation model of the costs of the waste disposal system was defined and it was used to produce preliminary results of its cost risk characteristics. Input data was synthesised by modifying the original coefficients of cost uncertainty to define a cost range for each cost item. This is a suitable method for demonstrating results obtainable by the model but it is not accurate enough for supporting decision making. Two key areas of further development were identified: the input data preparation and identifying and handling of (i.e. eliminating or merging) interacting cost elements in the simulation model. Further development in both of the mentioned areas can be carried out by co-operating with the power companies as they are the sources of the original data. (orig.)

    In this study the dynamics of risk perceptions related to bovine spongiform encephalopathy (BSE) held by Canadian consumers and cow-calf producers were evaluated. Since the first domestic case of BSE in 2003, Canadian consumers and cow-calf producers have needed to make decisions on whether or not their purchasing/production behavior should change. Such changes in their behavior may relate to their levels of risk perceptions about BSE, risk perceptions that may be evolving over time and be affected by BSE media information available. An econometric analysis of the behavior of consumers and cow-calf producers might identify the impacts of evolving BSE risk perceptions. Risk perceptions related to BSE are evaluated through observed market behavior, an approach that differs from traditional stated preference approaches to eliciting risk perceptions at a particular point in time. BSE risk perceptions may be specified following a Social Amplification of Risk Framework (SARF) derived from sociology, psychology, and economics. Based on the SARF, various quality and quantity indices related to BSE media information are used as explanatory variables in risk perception equations. Risk perceptions are approximated using a predictive difference approach as defined by Liu et al. (1998). Results showed that Canadian consumer and cow-calf producer risk perceptions related to BSE have been amplified or attenuated by both quantity and quality of BSE media information. Government policies on risk communications need to address the different roles of BSE information in Canadian consumers' and cow-calf producers' behavior.

    Since most of the empirical work on risk perception has been conducted in the 1970s and few studies are available that claim to span the full range of psychological, sociological and cultural variables, the Center of Technology Assessment in Stuttgart (Germany) has conducted a representative survey in the German State of Baden-Wuerttemberg on risk perception in the general population. In addition, a qualitative investigation based on a sample of 62 respondents was launched in 2001. The objective of the study was to determine the relative importance of psychometric, stigma-related, social value-related, trust-related and cultural variables in explaining risk perception and acceptance. The following report summarizes the results of these investigations. (orig.)

    In this study, the risk perception level of each light pollution type was analyzed, and the effects of the variables (e.g., psychometric paradigm factor, trust in the government, etc.) on the process of the increase in the risk perception were analyzed. For the sample population (1096 persons) in Korea, the risk perception levels of each light pollution type and other environmental and health risk factors were compared, and the relative magnitude was examined. In addition, to test which variables affect the group with high-risk perception of each light pollution type, a logistic regression analysis was performed. For the group with highest risk perception of light pollution, the odds ratios (OR) of all psychometric paradigms (excluding controllability) increased compared to those of the group with low-risk perception. Additionally, the level showing the acquisition of information from the media and the recollection level of media criticism on each light pollution type showed a statistically significant increase. Especially, the risk perception of light trespass increased as trust in the government decreased. The significance of this study includes the finding that the public's risk perception of light pollution was significantly affected by the psychometric paradigm factors. Moreover, this study analyzed the differences of the variables that affect the increase in the risk perception of each light pollution type and provided a theoretical framework that can practically reflect the strategy for the risk communication of light pollution.

    The purpose of this study was to investigate the contribution of actual cardiovascular disease (CVD) risk, as well as, individual, psychosocial, and work-related factors as predictors of CVD risk perception among Korean blue-collar workers. The participants were 238 Korean blue-collar workers who worked in small companies. Data were collected through a survey; anthropometric and blood pressure measures; and blood sampling for lipid levels. Blue-collar workers had high actual CVD risk and low CVD risk perception. The significant predictors of risk perception included perceived health status, alcohol consumption, knowledge of CVD risk, actual CVD risk, decision latitude, and shift work. The model explained 26% of the variance in CVD risk perception. The result suggests when occupational health nurses are giving routine health examination in small companies, they can enhance CVD risk perception in blue-collar workers by providing essential information about CVD risk factors and personal counseling on the individual worker's CVD risk status.

    Increasingly, support for water fluoridation has come under attack. We seek an explanation, focusing on the case of Waterloo, Ontario, where a 2010 referendum overturned its water fluoridation program. In particular, we test whether individuals perceive the risks of water fluoridation based not on 'hard' scientific evidence but on heuristics and cultural norms. A sample of 376 residents in Waterloo were surveyed in June 2012 using random digit dialing. We use factor analysis, OLS regression, as well as t-tests to evaluate a survey experiment to test the credibility hypothesis. Perceptions of fluoride as a risk are lower among those who perceive fluoride's benefits (B = .473, p < 0.001) and those whose cultural view is 'egalitarian' (B = .156, p < 0.05). The experiment shows a lower level of perception of fluoride's benefits among respondents who are told that water fluoridation is opposed by a national advocacy group (Group A) compared to those who are told that the government and the World Health Organization support fluoridation (Group B) (t = 1.6547, p < 0.05), as well as compared to the control group (t = 1.8913, p < 0.05). There is no difference between Group B and the control, possibly because people's already general support for fluoridation is less prone to change when told that other public organizations also support fluoridation. Public health officials should take into account cultural norms and perceptions when individuals in a community appear to rise up against water fluoridation, with implications for other public health controversies.

    Approximately 95% of older women have factors that put them at risk for developing cardiovascular disease, but research indicates many do not perceive themselves to be at risk. We examined older women's perceived risk for coronary heart disease (CHD) and the factors influencing their perceptions. We conducted a descriptive, qualitative study using in-depth, individual interviews and quantitative measures to assess perceived risk and risk factors. Twenty-four older African American and Caucasian women had a mean 4.46 cardiac risk factors but perceived their own CHD risk as unrealistically low at 1.95 cm (SD = 1.57, on 0-to-8 cm visual analogue scale). Narrative data clustered in themes that represented a lack of fact-based information and multiple misconceptions about CHD and prevention. Major improvements in CHD health are only achievable if risk factors are prevented. This research suggests older women have substantial needs for consistent CHD information and prevention guidance.

    2000-01-01

    Full Text Available This paper describes a study that is part of a multidisciplinary project examining the relationship between transport, air pollution and health in Guildford, a medium sized town in the UK. Real-time air quality monitoring revealed low levels of air pollution through vehicle emissions. However, the residents of the town claim that there is an air pollution problem, perceptions reinforced by visual and sensory feedback, i.e., people see dust, feel irritations to their eyes, noses and throats and smell exhaust fumes. It is shown that the higher people believe air pollution levels to be the more responsible they feel and the less trust they have in local authorities and technological developments. Beliefs about the health consequences of air pollution are not related to responsibility and trust. The findings support other studies on risk perception that have shown that people find a risk less acceptable when they have a lower trust in risk managers. It is concluded that these findings are of importance for the environmental education of the public generally and risk communication by local authorities in particular.

  6. A proposed risk acceptance criterion for nuclear fuel waste disposal

    International Nuclear Information System (INIS)

    Mehta, K.

    1985-06-01

    The need to establish a radiological protection criterion that applies specifically to disposal of high level nuclear fuel wastes arises from the difficulty of applying the present ICRP recommendations. These recommendations apply to situations in which radiological detriment can be actively controlled, while a permanent waste disposal facility is meant to operate without the need for corrective actions. Also, the risks associated with waste disposal depend on events and processes that have various probabilities of occurrence. In these circumstances, it is not suitable to apply standards that are based on a single dose limit as in the present ICRP recommendations, because it will generally be possible to envisage events, perhaps rare, that would lead to doses above any selected limit. To overcome these difficulties, it is proposed to base a criterion for acceptability on a set of dose values and corresponding limiting values of probabilities; this set of values constitutes a risk-limit line. A risk-limit line suitable for waste disposal is proposed that has characteristics consistent with the basic philosophy of the ICRP and UNSCEAR recommendations, and is based on levels on natural background radiation

    This screening level risk assessment evaluates potential adverse human health and ecological impacts resulting from continued operations of the calciner at the New Waste Calcining Facility (NWCF) at the Idaho Nuclear Technology and Engineering Center (INTEC), Idaho National Engineering and Environmental Laboratory (INEEL). The assessment was conducted in accordance with the Environmental Protection Agency (EPA) report, Guidance for Performing Screening Level Risk Analyses at Combustion Facilities Burning Hazardous Waste. This screening guidance is intended to give a conservative estimate of the potential risks to determine whether a more refined assessment is warranted. The NWCF uses a fluidized-bed combustor to solidify (calcine) liquid radioactive mixed waste from the INTEC Tank Farm facility. Calciner off volatilized metal species, trace organic compounds, and low-levels of radionuclides. Conservative stack emission rates were calculated based on maximum waste solution feed samples, conservative assumptions for off gas partitioning of metals and organics, stack gas sampling for mercury, and conservative measurements of contaminant removal (decontamination factors) in the off gas treatment system. Stack emissions were modeled using the ISC3 air dispersion model to predict maximum particulate and vapor air concentrations and ground deposition rates. Results demonstrate that NWCF emissions calculated from best-available process knowledge would result in maximum onsite and offsite health and ecological impacts that are less then EPA-established criteria for operation of a combustion facility.

    In this paper, risk communications among the Japan Radioisotope Association (JRIA), a local government and the general public which were carried out during the development process of a radioactive waste treatment facility in Takizawa Village, Iwate Prefecture are analyzed based on the articles of newspapers and the interviews with the concerned people. The analysis results show good risk communications were not carried out because of the absence of the confidence to the JRIA, decision making rules and the merits. In order to make good use of this experience for the future development of radioactive waste management facilities, the lessons learned from this case are summarized and the check lists for good risk communication are proposed.

      Environmental sustainability is a critical concern in health care. Similar to other professions, the practice of athletic training necessitates the use of a large quantity of natural and manufactured resources.   To examine the perceptions of the waste produced by the practice of athletic training and the green practices currently used by athletic trainers (ATs) to combat this waste.   Mixed-methods study.   Field setting.   A total of 442 ATs completed the study. Sixteen individuals participated in the qualitative portion.   Data from sections 2 and 3 of the Athletic Training Environmental Impact Survey were analyzed. Focus groups and individual interviews were used to determine participants' views of waste and the efforts used to combat waste. Descriptive statistics were used to examine types of waste. Independent t tests, χ 2 tests, and 1-way analyses of variance were calculated to identify any differences between the knowledge and use of green techniques. Interviews and focus groups were transcribed verbatim and analyzed inductively.   Participants reported moderate knowledge of green techniques (3.18 ± 0.53 on a 5-point Likert scale). Fifty-eight percent (n = 260) of survey participants perceived that a substantial amount of waste was produced by the practice of athletic training. Ninety-two percent (n = 408) admitted they thought about the waste produced in their daily practice. The types of waste reported most frequently were plastics (n = 111, 29%), water (n = 88, 23%), and paper for administrative use (n = 81, 21%). Fifty-two percent (n = 234) agreed this waste directly affected the environment. The qualitative aspect of the study reinforced recognition of the large amount of waste produced by the practice of athletic training. Types of conservation practices used by ATs were also explored.   Participants reported concern regarding the waste produced by athletic training. The amount of waste varies depending on practice size and setting

    Full Text Available Objectives This study examined variations in the perceptions of dioxin risk among social groups defined by geographical living location, environmental education, and occupation. Dioxin risk perceptions were analyzed according to values, risk awareness, knowledge, and behavioral preferences. Methods A quasi-experimental survey was designed and conducted on individuals from seven experimental groups in Jeonju city, South Korea, including: people living near incineration facilities; people living far from incineration facilities; governmental experts; nongovernmental organization members; office workers in developmental institutes or banks; students who were enrolled in environmental-related classes; and students who were enrolled in business-related classes. Results The results show variations among groups in values, awareness and behavioral preferences. Particular attention should be given to the result that groups with higher connectedness- to-nature values show higher willingness-to-act (WTA for risk reduction. Result s can be summarized as follows. First, awareness is associated with one’s geographical setting. Second, values and WTA behaviors are related to one’s environmental-related education and occupation. Third, values are significantly related to WTA behaviors. Conclusions Different cultures, in terms of values or worldview, among groups influence their perceptions of dioxin risk and choices of risk reduction behaviors. It is important to consider values in communicating complicated long-term risk management involving public participation. Further research should be continuously conducted on the effects of multiple dimensions of values on one’s WTA for risk reduction behaviors.

    1993-01-01

    Public support for nuclear power has declined greatly, driven by a number of powerful forces and events. Numerous studies have demonstrated the public's extreme perceptions of risk and negative attitudes regarding nuclear power. This negativity is remarkable in light of the confidence most technical analysts have regarding the safety of this technology. Public fears and opposition to nuclear power can be seen as a crisis in confidence, a profound breakdown in trust in the scientific, governmental, and industrial managers of nuclear technologies. The problem is not due to public ignorance or irrationality, but is deeply rooted in individual psychology and the adversarial nature of our social, institutional, legal, and political systems of risk management. In the absence of revolutionary changes in the ways that risks are managed in our society, it is unlikely that public trust, confidence, and acceptance of nuclear power can be regained

    To determine women's perceived personal and comparative risks of breast cancer, and to examine the relationships with risk factors. Despite the increasing incidence of breast cancer in younger women and the availability of screening, women's health behaviors have not advanced accordingly. A cross-sectional survey design utilized a convenience sample of 222 women in their 30s and 40s recruited from community settings in Seoul. Self-administered questionnaire data were analyzed by descriptive statistics, the chi-squared test, and ANOVA. Risk perception levels differed significantly by breast cancer risk factors. Half of the women were optimistic about their breast cancer risk, while perceived personal risk did not reflect women's own risk factors and comparative risk differed only by the practice of clinical breast exam. Women's knowledge and awareness of their breast cancer risk factors need to be improved for appropriate risk perception and health behaviors, and accurate risk estimation could be utilized to educate them in clinical settings. © 2013.

  15. Risks of municipal solid waste incineration: an environmental perspective.

    Denison, R A; Silbergeld, E K

    1988-09-01

    The central focus of the debate over incineration of municipal solid waste (MSW) has shifted from its apparent management advantages to unresolved risk issues. This shift is a result of the lack of comprehensive consideration of risks associated with incineration. We discuss the need to expand incinerator risk assessment beyond the limited view of incinerators as stationary air pollution sources to encompass the following: other products of incineration, ash in particular, and pollutants other than dioxins, metals in particular; routes of exposure in addition to direct inhalation; health effects in addition to cancer; and the cumulative nature of exposure and health effects induced by many incinerator-associated pollutants. Rational MSW management planning requires that the limitations as well as advantages of incineration be recognized. Incineration is a waste-processing--not a waste disposal--technology, and its products pose substantial management and disposal problems of their own. Consideration of the nature of these products suggests that incineration is ill-suited to manage the municipal wastestream in its entirety. In particular, incineration greatly enhances the mobility and bioavailability of toxic metals present in MSW. These factors suggest that incineration must be viewed as only one component in an integrated MSW management system. The potential for source reduction, separation, and recycling to increase the safety and efficiency of incineration should be counted among their many benefits. Risk considerations dictate that alternatives to the use of toxic metals at the production stage also be examined in designing an effective, long-term MSW management strategy.

    Expert's risk evaluation of radiation exposure strongly influences the public's risk perception. Experts can inform laypersons of significant radiation information including health knowledge based on experimental data. However, some experts' radiation risk perception is often based on non-conclusive scientific evidence (i.e., radiation levels below 100 millisievert), which is currently under debate. Examining perception levels among experts is important for communication with the public since these individual's opinions have often exacerbated the public's confusion. We conducted a survey of Korean radiation researchers to investigate their perceptions of the risks associated with radiation exposure below 100 millisievert. A linear regression analysis revealed that having ≥ 11 years' research experience was a critical factor associated with radiation risk perception, which was inversely correlated with each other. Increased opportunities to understand radiation effects at perception of radiation exposure. In addition, radiation researchers conceived that more scientific evidence reducing the uncertainty for radiation effects perception of radiation exposure.

  19. A framework for understanding risk perception, explored from the perspective of the water practitioner.

    2014-02-01

    Sustainable urban water systems are likely to be hybrids of centralized and decentralized infrastructure, managed as an integrated system in water-sensitive cities. The technology for many of these systems is available. However, social and institutional barriers, which can be understood as deeply embedded risk perceptions, have impeded their implementation. Risk perceptions within the water sector are often unrecognized or unacknowledged, despite their role in risk management generally in informing value judgments and specifically in ranking risks to achieve management objectives. There has been very little examination of the role of these risk perceptions in advancing more sustainable water supply management through the adoption of alternative sources. To address this gap, this article presents a framework that can be used as a tool for understanding risk perceptions. The framework is built on the relational theory of risk and presents the range of human phenomena that might influence the perception of an "object at risk" in relation to a "risk object." It has been synthesized from a critical review of theoretical, conceptual, and empirical studies of perception broadly and risk perception specifically, and interpreted in relation to water practitioners. For a water practitioner, the risk object might be an alternative water system, a component, a process, or a technology, and the object at risk could be public or environmental health, profitability, or professional reputation. This framework has two important functions: to allow practitioners to understand their own and others' risk perceptions, which might differ, and to inform further empirical research. © 2013 Society for Risk Analysis.

    Highlights: • Contribution to the scientific literature by examining the relationship between concern for the environment and waste disposal in the frame of household waste treatment mechanism specifically in developing countries. • The awareness of the citizens satisfaction level and the local existing capacities in developing countries significantly contribute to decision making on MSW management sustainability in Palestine and other developing countries when applied. • Identification of the differences and similarities among DC resulting to failures or success in WM field. - Abstract: Municipal solid waste (MSW) piling up is becoming a serious problem in all developing countries (DC) as a result of inequitable waste collection and treatment. Citizens’ collaboration is partly based on understanding their views and their active involvement in MSW planning; on the other hand the assessment of the perception of hazardousness related with MSW is considered rather important as well since the identification of the weak points of the applied MWM strategy is eased and the level of required training is determined. Researchers implemented a case study in the West Bank (WB) and Gaza Strip (GS) regions of Palestine, taking into consideration previous researches in other developing countries. They reached to safe and useful conclusions regarding the parameters which mean the greatest in the waste management field as far as DC are concerned. Lack of skilled manpower, irregular collection services, inadequate equipment used for waste collection, inadequate legal provisions, and resource constraints are additional factors that are confirmed to be challenging the waste management scenarios in all DCs today. The research takes those factors under consideration but focuses on the educational gap and the results revealed interesting trends a significant relationship between respondent’s educational attainment and their awareness of hazardous waste (hazard perception); the

    There are reports of increased sexual risk behavior among people on highly active antiretroviral therapy (HAART) due to beliefs about risk of HIV transmission when on HAART. In a cross-sectional study (Seropositive Urban Men's Study), we examined the relationship between risk perception and sexual risk behavior among sexually active, culturally diverse HIV positive men who have sex with men (N = 456). Less than twenty-five percent engaged in unprotected anal sex (either with an HIV negative, or unknown-status partner, or an HIV positive partner) within the past 3 months. Most men believed there was significant health risk (to partner or self) associated with unprotected sex when on HAART. There was no increased risk behavior associated with being on HAART, although the perception of negative health consequences, including HIV transmission, when on HAART was significantly lower for the relatively small subset of men who reported unprotected sex. Prevention strategies need to be tailored to address risk perception associated with HAART.

    Serious bottle-necks exist in the nuclear fuel cycle and will continue for the next decade. A total of 800 nuclear reactors are now in operation. 153 nuclear power plants represent an installed capacity of 70 GVe. Until 1985 five hundred nuclear power plants will be in operation from which up to this date 53.000 t uranium will have been discharged. Part of this will have to be reprocessed. Associated with the above mentioned amount are 500 t plutonium and 1.500 t highly radioactive wastes. Two risks for the population have to be considered: firstly, the effect of small amounts of radioactive substances released during normal operation of nuclear power plants (the annual dose is about 1 mrem per person). Secondly, the possibility of the release of great amounts of radioactivity during heavy accidents (the probability for which is extremely small). A series of feasible possibilities for conditioning are shown. Firstly, the wastes are packed in substances which are insoluble in water. Secondly, for low and medium wastes these can be mixed with concrete or bitumen and filled into stable containers. Thirdly, the wastes could also be solidified. Fourthly, the wastes could be enclosed in small glass spheres which are embedded in a metal matrix. (H.G.)

    The Tank Waste Remediation System (TWRS) mission is to store, treat, and immobilize the highly radioactive Hanford Site tank wastes and encapsulated cesium and strontium materials in an environmentally sound, safe, and cost effective manner. Additionally, the TWRS conducts, as part of this mission, resolution of safety issues associated with the wastes within the 177 underground radioactive waste tanks. Systems engineering principles are being applied to determine the functions and establish requirements necessary for accomplishing the TWRS mission (DOE 1994 draft). This systematic evaluation of the TWRS program has identified key decisions that must be executed to establish mission scope, determine requirements, or select a technical solution for accomplishing identified functions and requirements. Key decisions identified through the systematic evaluation of the TWRS mission are presented in this document. Potential alternative solutions to each decision are discussed. After-discussion and evaluation of each decision with effected stakeholder groups, the US Department of Energy (DOE) will select a solution from the identified alternatives for implementation. In order to proceed with the development and execution of the tank waste remediation program, the DOE has adopted a planning basis for several of these decisions, until a formal basis is established. The planning bases adopted by the DOE is continuing to be discussed with stakeholder groups to establish consensus for proceeding with proposed actions. Technical and programmatic risks associated with the planning basis adopted by the DOE are discussed

    A research group at the Nuclear Research Centre, Julich, has attempted to trace public attitudes to nuclear power and their roots. The structure of attitudes, types of reasoning and the processes involved in deciding about nuclear power were measured. Intuitive perceptions of technology and risk were studied. Attitudes to nuclear energy are found to be the result of intuitive processes and opposition is 'natural' on the basis of intuitive reasoning. Many people who believe nuclear power to be hazardous nevertheless will accept it as inevitable for the economic advantages it will bring in the future. (U.K.)

    Cardiovascular risk factors (CVRFs) self-perception by women may be inaccurate. A questionnaire was completed anonymously Online by women who self-reported their personal CVRF levels including age, weight, contraceptive use, menopausal status, smoking, diet and physical activities. Self-perceived risk was matched to actual cardiovascular risk according to the Framingham score. Among 5,240 young and middle-aged women with a high educational level, knowledge of personal CVRFs increased with age, from 51-90% for blood pressure (BP), 22-45% for blood glucose and 15-47% for blood cholesterol levels, between 30 and 65 years, respectively. This knowledge was lower for smoking compared with nonsmoking women: 62.5% vs. 74.5% for BP (P self-perception of individual risk are inaccurate in women. Educational interventions should be emphasized. Copyright © 2017 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

    Surrounded by landfills, and toxic and hazardous facilities, Altgeld Gardens is located in a "toxic doughnut". With high rates of environmentally-related conditions, residents have called for a community-based environmental health assessment to improve overall health in their community. The purpose of this study was to investigate the attitudes and beliefs of environmental health risks of Altgeld's residents which would assist community organizing efforts and provide the groundwork for a community-based environmental health assessment. A questionnaire was designed and administered to 42 Altgeld residents who also participated in focus groups to assess their perceptions of environmental health risks. All participants were Altgeld residents for at least two years and were fairly representative of the broader community. Physical and social hazards were primarily identified as posing risks to participants' family and the broader community. Physical hazards included the dumping of hazardous waste and landfills; social hazards were crime and drugs. These findings have been useful in community organizing efforts and in program planning for local community-based organizations and public health agencies. The results have also been used to prioritize health and environmental risk issues impacting the community.

    The central concern in this Symposium is with risk to human health and life. Health risk includes the possibility of deaths (mortality), either immediate or delayed, and less severe health effects due to injury and illness (morbidity). Risk is defined as the product of the magnitude and the probability so that where it may be expressed quantitatively it is stated in units of harm per unit time (e.g. deaths per year or deaths per year per million of population). The 15 papers presented at this conference discuss the measurement, analysis perception, and management of risk. Six papers judged to be in scope were indexed for INIS

    The aim of the paper is to analyze how Finns perceive the risks of uranium mining and nuclear waste management. In social science quite much research has been done on the issue of how people perceive the risks of nuclear waste and nuclear waste management, but not much has been done in analyzing the similarities and differences of risk perception (and ethical considerations) of the utmost ends of nuclear fuel cycle. There have been some changes in Finnish nuclear policy during ongoing decade, which make this type of study interesting: decision on the fifth nuclear power plant was done in 2002, the site for spent nuclear fuel has been chosen in 2001 and in 2010 the Parliament will decide which of three competitors will get the permission to construct the sixth nuclear power plant. This national nuclear renaissance was accompanied with the uranium boom, which started in 2005. New international interest in nuclear power had raised the price of uranium. International mining companies started uranium explorations because Finnish bedrock is the oldest in Europe, and it is similar with and also of the same age as is that of the great uranium producers, Canada and Australia. The analysis of risk perceptions between uranium questions and spent nuclear fuel is based on the national survey data (N=1180) gathered in 2007

    Hybrid systems (source-driven subcritical reactors), are investigated at CEA, mainly from a conceptual point of view, in order to assess their potential to transmute radioactive wastes (mainly long-lived fission products, LLFP) and their potential to insure a minimal long-term radiological risk related both to the fuel inventory inside the system and to the full fuel cycle (mass flows, reprocessing transport, waste disposal). The physics of these systems has been explored and work is in progress both in the field of basic data and INC code validation, in the frame of international collaborations and in the field of conceptual design studies. The most interesting feature of subcritical source-driven system is related to the possibility to obtain an {open_quotes}excess{close_quotes} of neutrons per fission, which can be used to reduce the long-term radiological risk. A specific example will be discussed here.

    Full Text Available The issue of disposal of municipal solid waste (MSW generated in households in the cities, has sparked debates and demanded research papers in order to promote and disseminate the handling and packaging suitable for the trash. The way of handling these wastes and their disposal in the city of Ipameri-GO and destination that provides this population has caused serious inconvenience to the community. Therefore, this work aimed, through interviews with residents of different neighborhoods of Ipameri, identify problems related to the management of household waste and diagnose the level of perception of the subject population. It was observed in this study that the handling of the solid waste in Ipameri has proved inefficient further by a lack of public education policy and hence the environment, in which the lack of activity of the population. The population in theoretical and scientific knowledge is lacking, regardless of social and economic class, although empirically this same population, presents itself willing to perform the selective collection and recycling of solid waste. This fact raises larger government incentives and investments in educational policy so that we can develop a policy for Environmental Education (EE, to be fruitful and lasting.

    Recent research has shown that by decoupling the risk response behaviour of consumers into the separate components of risk perception and risk attitude, a more robust conceptualization and prediction of consumers’ reactions to food safety issues is possible. Furthermore, it has been argued that the influence of risk attitudes and risk perceptions on consumer risk behaviour for contaminated food products can be used to formulate effective agricultural policies and strategies in case of a food ...

  16. Preparing for Local Adaptation: Understanding Flood Risk Perceptions in Pittsburgh

    Klima, K.; Wong-Parodi, G.

    2015-12-01

    The City of Pittsburgh experiences numerous floods every year. Aging and insufficient infrastructure contribute to flash floods and to over 20 billion gallons of combined sewer overflows annually, contaminating Pittsburgh's streets, basements, and waterways. Climate change is expected to further exacerbate this problem by causing more intense and more frequent extreme precipitation events in Western Pennsylvania. For a stormwater adaptation plan to be implemented effectively, the City will need informed public support. One way to achieve public understanding and support is through effective communication of the risks, benefits, and uncertainties of local flooding hazards and adaptation methods. In order to develop these communications effectively, the city and its partners will need to know what knowledge and attitudes the residents of Pittsburgh already hold about flood risks. Here we seek to (1) identify Pittsburgh residents' knowledge level, risk perception and attitudes towards flooding and storm water management, and (2) pre-test communications meant to inform and empower Pittsburghers about flood risks and adaptation strategies. We conduct a city-wide survey of 10,000 Pittsburgh renters and homeowners from four life situations: high risk, above poverty; high-risk, below poverty; low risk, above poverty; and low-risk, below poverty. Mixed media recruitment strategies (online and paper-based solicitations guided/organized by community organizations) assist in reaching all subpopulations. Preliminary results suggest participants know what stormwater runoff is, but have a weak understanding of how stormwater interacts with natural and built systems. Furthermore, although participants have a good understanding of the difference between green and gray infrastructure, this does not translate into a change in their willingness to pay for green infrastructure adaptation. This suggests additional communications about flood risks and adaptation strategies.

    Climate change is generally considered as one of the greatest challenges our world is facing. In the case of Greece climatic change seems to be associated with sea level rise, increase in temperature, variation in precipitation patterns, and extreme weather events. As a result of climate pattern changes a series of consequences are expected in areas involving build environment, infrastructures, health and various sectors of the economy. Even though climate change is probably going to affect Greece in terms of human welfare and economic growth, public perception and attitude do not always identify it as the most important, amongst others, environmental area of concern, or compared to various socio-economic issues. Considering that topics related to climate change involve a certain degree of uncertainty public perception seems to be important when dealing with adaptation strategies to manage or prevent risks from climate change impact and therefore people's reaction to risks seem to be an issue of great importance in future policy planning and implementation. The key issue of this paper is to investigate and analyse public perception in Greece as regards to climate change risk. Through a questionnaire survey this research investigates people's understanding, specific knowledge, opinion, awareness, emotions, behavior with regards to climate change risks and their willingness to pay in order to minimize or prevent risk. In addition, it examines people's willingness to alter current lifestyle and adapt to a changing climate. The information derived from survey data concern the topics and the perceived importance of the causes of the climate change between certain groups of people; the analysis of the data is focused on the correlation between perceived risk and knowledge about the issues involved. Rather than applying a specific technique extensively, we choose to deploy a number of methodologies with which we are able to draw different aspects from the data. To this

    Climate change is expected to severely impact agricultural practices in many important food-producing regions, including the Northeast United States. Changing climate conditions, such as increases in the amount of rainfall, will require farmers to adapt. Yet, little is known with regard to farmers' perceptions and understandings about climate change, especially in the industrialized country context. This paper aims at overcoming this research limitation, as well as determining the existing contextual, cognitive, and psychological barriers that can prevent adoption of sustainable practices of farmers in New York State. The study is framed within the adaptive capacity and risk perception literature, and is based on a qualitative analysis of in-depth interviews with farmers in 21 farms in two counties in Central New York. The results reveal diverging views about the long-term consequences of climate change. Results also reveal that past experience remains as the most important source of information that influences beliefs and perceptions about climate change, confirming previous research.

    1998-01-01

    This paper explores the hypothesis that a very different curve in perceptions of managed technological risks may be observed over time in experts, political decision makers, and the general public. Experts may have high risk perceptions during the phase of technology development, with the outcome of risk-reducing design. Members of the public, in their role as consumers, may perceive new technologies as very risky until such time as they have become integrated into everyday practice. At that time, with feedback from experience, risk perceptions may rise again in experts. The perceptions of legislators may respond to those expressed by either or both groups. Economic and social theories of risk perception are cited to construct the curve of risk perception for each group. (authors)

    2018-05-16

    Experimental and survey research spanning the last two decades concludes that people who are more risk tolerant are more likely to engage in risky health activities such as smoking and heavy alcohol consumption, and are more likely to be obese. Subjective perceptions of the risk associated with different activities have also been found to be associated with health behaviors. While there are numerous studies that link risk perceptions with risky behavior, it is notable that none of these controls for risk aversion. Similarly, studies that control for risk aversion fail to control for risk misperceptions. We use a survey of 474 men and women to investigate the influence of risk aversion, risk misperceptions, and cognitive ability on the choice to engage in behaviors that either increase or mitigate cancer risk. We measure optimism in two dimensions: baseline optimists are those who inaccurately believe their cancer risk to be below its expert-assessed level, while control optimists are those who believe they can reduce their risk of cancer (by changing their lifestyle choices) to a greater extent than is actually the case. Our results indicate that baseline optimism is significantly and negatively correlated with subjects' tendencies to engage in cancer-risk-reducing behaviors, and positively correlated with risky behaviors. Subjects' control misperceptions also appear to play a role in their tendency to engage in risky and prevention behaviors. When controlling for both of these types of risk misperception, risk aversion plays a much smaller role in determining health behaviors than found in past studies. © 2018 Society for Risk Analysis.

    This research demonstrates that higher levels of mental toughness provide cognitive-perceptual processing advantages when evaluating risk. No previous research, however, has examined mental toughness in relation to perception of risk and paranormal belief (a variable associated with distorted perception of causality and elevated levels of perceived risk). Accordingly, the present paper investigated relationships between these factors. A sample of 174 participants completed self-report measures assessing mental toughness, general perception of risk, and paranormal belief. Responses were analyzed via correlations and moderation analyses. Results revealed that mental toughness correlated negatively with perception of risk and paranormal belief, whereas paranormal belief correlated positively with perception of risk. For the moderation effects, simple slopes analyses indicated that high levels of MT and subfactors of commitment and confidence reduced the strength of association between paranormal belief and perceived risk. Therefore, MT potentially acts as a protective factor among individuals who believe in the paranormal, reducing the tendency to perceive elevated levels of risk.

    2015-01-01

    The presented study is part of the EU-Project Low EMF Exposure Future Networks (LEXNET), which deals among other things with the issue of whether a reduction of the radiofrequency (RF) electro-magnetic fields (EMF) exposure will result in more acceptance of wireless communication networks in the public sphere. We assume that the effects of any reduction of EMF exposure will depend on the subjective link between exposure perception and risk perception (RP). Therefore we evaluated respondents’ RP of different RF EMF sources and their subjective knowledge about various exposure characteristics with regard to their impact on potential health risks. The results show that participants are more concerned about base stations than about all other RF EMF sources. Concerning the subjective exposure knowledge the results suggest that people have a quite appropriate impact model. The question how RF EMF RP is actually affected by the knowledge about the various exposure characteristics was tested in a linear regression analysis. The regression indicates that these features – except distance – do influence people’s general RF EMF RP. In addition, we analyzed the effect of the quality of exposure knowledge on RF EMF RP of various sources. The results show a tendency that better exposure knowledge leads to higher RP, especially for mobile phones. The study provides empirical support for models of the relationships between exposure perception and RP. It is not the aim to extrapolate these findings to the whole population because the samples are not exactly representative for the general public in the participating countries. PMID:25629026

  8. Health risks occurring when color is percepted under led lighting

    V.A. Kaptsov

    2017-06-01

    Full Text Available The article deals with problems of color perception under LED lighting. We revealed that inadequate perception of a signal color by a driver led to greater risks of transport accidents. We reviewed both Jung-Helmholtz three-color hypothesis and a modern one based on fiber-optical approach to functioning of "Mueller cells and cones" system. We made an attempt to explain a number of effects related to visibility curves and time delays when defining color of light signals. Our research on assessing influence exerted by LED lighting on functional state and working capacity of railway workers during which we applied occupational selection techniques revealed negative changes. We proved there was a decrease in functional resistance to color sense between red and green signals as well as longer response time for complicated sight-motor reaction and significant decrease in readiness to emergency actions (resistance to monotony in examined individuals. The article also contains data on time peculiarities which are characteristic for defining signals color in relation to red signal (650 nm. We showed that when red color LEDs with wave length much shorter than 650 nm were used in signaling devices it caused risks of inadequate color detection, longer reaction to inhibiting signals, and greater possibility of transport accidents and negative events in everyday life. These peculiarities should be taken into account when designing traffic lights and other signaling devices which provide transport safety. We also proved that signaling traffic lights for transport systems should be designed allowing for physiology of color perception by a human visual analyzer; application of LEDs with wave length shorter than 650 nm should be absolutely excluded

    2017-09-01

    This study clarifies the associations between accident history, perception of the riskiness of road travel and traffic safety behaviours by taking into account the number and severity of accidents experienced. A sample of 525 road users in Cameroon answered a questionnaire comprising items on perception of risk, safe behaviour and personal accident history. Participants who reported involvement in more than three accidents or involvement in a severe accident perceived road travel as less risky and also reported behaving less safely compared with those involved in fewer, or less severe accidents. The results have practical implications for the prevention of traffic accidents. Practitioner Summary: The associations between accident history, perceived risk of road travel and safe behaviour were investigated using self-report questionnaire data. Participants involved in more than three accidents, or in severe accidents, perceived road travel as less risky and also reported more unsafe behaviour compared with those involved in fewer, or less severe accidents. Campaigns targeting people with a less serious, less extensive accident history should aim to increase awareness of hazards and the potential severity of their consequences, as well as emphasising how easy it is to take the recommended preventive actions. Campaigns targeting those involved in more frequent accidents, and survivors of serious accidents, should address feelings of invulnerability and helplessness.

  10. Neural Correlates of Risk Perception: HIV vs. Leukemia

    Full Text Available Field studies on HIV risk perception suggest that people may rely on impressions they have about the safety of their partner. Previous studies show that individuals perceived as 'risky' regarding HIV elicit a differential brain response in both earlier (~200 - 350 ms and later (~350 - 700 ms time windows compared to those perceived as safe. This raises the question whether this ERP response is specific to contagious life-threatening diseases or a general mechanism triggered by life-threatening but non-contagious diseases. In the present study, we recorded dense sensor EEG while participants (N = 36 evaluated photographs of unacquainted individuals for either HIV or leukemia risk. The ERP results replicated previous findings revealing earlier and later differential brain responses towards individuals perceived as high risk for HIV. However, there were no significant ERP differences for high vs. low leukemia risk. Rather than reflecting a generic response to disease, the present findings suggest that intuitive judgments of HIV risk are at least in part specific to sexually transmitted diseases.

    Improvements in communications technology enable consumers to receive information through diverse channels. In the case of avian influenza, information repeated by the mass media socially amplifies the consumer awareness of risks. Facing indeterminate risks, consumers may feel anxious and increase their risk perception. When consumers trust the information published by the media, their uncertainty toward avian influenza may decrease. Consumers might take some actions to reduce risk. Therefore, this study focuses on relationships among trust in messages, risk perception and risk reduction preferences. This study administered 525 random samples and consumer survey questionnaires in different city of Taiwan in 2007. Through statistical analysis, the results demonstrate: (1) the higher the trust consumers have in messages about avian influenza, the lower their risk perceptions are; (2) the higher the consumers’ risk perceptions are and, therefore, the higher their desired level of risk reductive, the more likely they are to accept risk reduction strategies; (3) consumer attributes such as age, education level, and marital status correlate with significant differences in risk perception and risk reduction preferences acceptance. Gender has significant differences only in risk reduction preferences and not in risk perception. PMID:23066394

    Perceptions of risks associated with mobile phones, base stations, and other sources of electromagnetic fields (EMF) were examined. Data from a telephone survey conducted in the German- and French-speaking parts of Switzerland are presented (N = 1,015). Participants assessed both risks and benefits associated with nine different sources of EMF. Trust in the authorities regulating these hazards was assessed as well. In addition, participants answered a set of questions related to attitudes toward EMF and toward mobile phone base stations. According to respondents' assessments, high-voltage transmission lines are the most risky source of EMF. Mobile phones and mobile phone base stations received lower risk ratings. Results showed that trust in authorities was positively associated with perceived benefits and negatively associated with perceived risks. People who use their mobile phones frequently perceived lower risks and higher benefits than people who use their mobile phones infrequently. People who believed they lived close to a base station did not significantly differ in their level of risks associated with mobile phone base stations from people who did not believe they lived close to a base station. Regarding risk regulation, a majority of participants were in favor of fixing limiting values based on the worst-case scenario. Correlations suggest that belief in paranormal phenomena is related to level of perceived risks associated with EMF. Furthermore, people who believed that most chemical substances cause cancer also worried more about EMF than people who did not believe that chemical substances are that harmful. Practical implications of the results are discussed.

    Full Text Available Background & aim: AIDS is one of the major public health challenges all over the world. Perceived risk is a significant predictor of high-risk behaviors related to AIDS. Women constitute more than half of the HIV patients, and the rate of female sex workers with AIDS is more than the rest of female population. Therefore, the present study aimed to evaluate AIDS risk perception and its related factors in females with high-risk behaviors in Mashhad, Iran. Methods:This descriptive study was performed on 58 women who were arrested on prostitution charges and imprisoned in Mashhad Vakil Abad Prison in 2013. The data were collected using self-designed questionnaires assessing knowledge regarding AIDS as well as sexual activities and also perceived risk of HIV questionnaire. One-way ANOVA, independent samples t-test, linear regression, and Chi-square tests were run, using SPSS version 16. Results: The mean score of HIV risk perception was 18.43±5.92, which was average. There was a significant relationship between the mean score of perceived risk of HIV and knowledge regarding AIDS (P=0.005, alcohol consumption (P=0.04, history of addiction (P=0.008, using contraceptive methods (P=0.01, condom use during intercourse (P=0.02, voluntary HIV testing (P=0.001, and follow-up of HIV test (P=0.009. Conclusion:The findings of the present study revealed that knowledge, alcohol consumption, history of addiction, contraceptive methods, the rate of condom use during intercourse, as well as voluntary HIV testing and follow-up were associated with perceived risk of HIV infection. Therefore, taking the necessary steps towards health promotion through appropriate training and interventional approaches seems to be mandatory for reducing high-risk behaviors in populations with low risk perception.

    2001-01-01

    Due to the increasing public awareness of the potential risks associated with waste transport, the environmental impact assessment of this activity has become an issue of major importance. This paper presents a project proposal, which can establish a national action plan for waste transport evaluation. Such a programme is sustained by the necessity to obtain an adequate method for the rapid and efficient estimation of individual and social risks due to the transport of hazardous substances in Romania. The main objective is to develop regional strategies for risk assessment in comprising: establishing the areas that must be investigated and their particular characteristics; identifying the transport activities in the areas; determining hazards; establishing the analysis criteria and prioritizing the study areas; evaluating continuous emissions; studying major accidents; studying population health; classifying the risks; establishing regional strategies; implementing political and regulatory measures. The project expectation is to provide a decision tool for risk managers and authorities in order to control or limit transportation and the storage of hazardous substances.(author)

  16. Do beef risk perceptions or risk attitudes have a greater effect on the beef purchase decisions of Canadian consumers?

    Cluster analysis is applied in this study to group Canadian households by two characteristics, their risk perceptions and risk attitudes toward beef. There are some similarities in demographic profiles, meat purchases, and bovine spongiform encephalopathy (BSE) media recall between the cluster that perceives beef to be the most risky and the cluster that has little willingness to accept the risks of eating beef. There are similarities between the medium risk perception cluster and the medium risk attitude cluster, as well as between the cluster that perceives beef to have little risk and the cluster that is most willing to accept the risks of eating beef. Regression analysis shows that risk attitudes have a larger impact on household-level beef purchasing decisions than do risk perceptions for all consumer clusters. This implies that it may be more effective to undertake policies that reduce the risks associated with eating beef, instead of enhancing risk communication to improve risk perceptions. Only for certain clusters with higher willingness to accept the risks of eating beef might enhancing risk communication increase beef consumption significantly. The different role of risk perceptions and risk attitudes in beef consumption needs to be recognized during the design of risk management policies.

    Organizations may view outsourcing as a way to eliminate risk. This application uses a decision analytic approach to determine which risks can be shared or shifted to vendors and which ones should be borne by the buyer. In this case, we found that allocating risks incorrectly could increase costs dramatically. This approach was used to develop the Request for Proposals (RFP) for the U.S. Department of Energy's (DOE's) privatization initiative for the Hanford Tank Waste Remediation System (TWRS). We describe this application and/SUMmarize technical and organizational lessons learned in the years following. The model used an assessment protocol to predict how vendors would react to proposed risk allocations in terms of their actions and their pricing

  18. A common vision of energy risk? Energy securitisation and company perceptions of risk in the EU

    Full Text Available In the European Union, energy security is provided by EU institutions, member states and commercial energy companies. However, despite the important role companies play in the provision of European energy security, it is not immediately evident to what extent the interests of the internationally operating energy firms are in line with the energy security preferences held by EU institutions. Analysing this relationship from the perspective of perceptions of energy security and energy business risk, this paper examines the extent to which there is a convergence between the energy securitisation of the European Commission and the observation of business risk as perceived by major European and international energy firms. It finds that while there are some significant areas where Commission securitisation contradicts energy company interests (e.g. climate change and energy prices there is also a high degree of convergence, in particular regarding perceptions of upstream political risk.

    Full Text Available Perception of environmental risks to the population is a priority issue for the bodies and administrations responsible for managing them. There are few studies on the perception of the risk to RF, but all of them report high levels of concern. This study describes and analyzes the RF risk perception of mothers belonging to the INMA-Gipuzkoa project.Data on perception were collected by means of two questionnaires given to mothers in two different periods. During pregnancy, 625 mothers chose the five relevant environmental issues in their place of residence from a list of 16. When their children were 8, 386 mothers rated, on a scale from 0 to 10, their perception of their levels of exposure to RF and the health risk derived from such exposure.During pregnancy, 31.8 % of mothers chose proximity to RF antennas as one of the 5 most important environmental problems. When their children were 8, 98.0 % and 90.3 % of women reported medium or high perception values (between 5 and 10 regarding exposure and health risk, respectively. A moderate correlation was found between exposure perception and risk perception (0.5. There is no association between RF exposure perception and actual levels measured inside homes.Knowing the factors associated with the perception of risks by the population will be useful to manage them properly.

    The importance of studying the relationship with the natural hazard events from a psycho-social perspective is fundamental by the experience with past disasters as much as by the research in the field that proved that the people's psychologic structures may constitute a starting point for risk reduction. People's psycho-behavioural patterns contain conscious or unconscious references to the environmental risk, thus creating certain adjustment strategies and mechanisms, with a certain degree of psychological vulnerability. In modern man's case, the high level of awareness in front of natural dangers, doubled by the perception of the environment's unsafety, experienced as a lack of control, brings to attention nowadays the problematic of the analysis of natural risk perception, as a main factor in the adjustment of human communities' capacity of adapting to the natural environment's dynamics. The major objective of this present work is, based on the development of an efficient evaluation methodology, to identify specific relational patterns to seismic risk in Bucharest, function the characteristics of the urban environment, the social, economical and psychological vulnerability, with results that can be applied for disaster management. For explaining human reactions and the way in which they perceive and evaluate the psychological resources, on a daily basis, but also in risk situations (earthquakes), a multi-modal questionnaire was conceived through qualitative methods (a focus group, along with experts from the Public and Administrative Sciences National School, Risk Communication Center). The questionnaire was structured on a 49 items sequence, in which were included different type of questions (with single or multiple answers, open questions etc), and also questions using different scaling methods. The items caught cognitive elements (expectations, anticipations and negative or positive judgments regarding risk element), affective (feelings) and behavioral

    In this study, the difference between the risk perception of electromagnetic waves from cellular phones and the risk perception of other factors such as environment and food was analyzed. The cause of the difference in the psychological and social factors that affect the group with high risk perception of electromagnetic waves was also analyzed. A questionnaire survey on the risk perception of electromagnetic waves from cellular phones was carried out on 1001 subjects (men and women) over the age of 20. In the group with high risk perception of electromagnetic waves from cellular phones, women had higher risk perception than men. Logistic regression analysis, where the group with high risk perception of electromagnetic waves and the group with low risk perception were used as dependent variables, indicated that the risk perception of electromagnetic waves in women was 1.815 times statistically significantly higher than the risk perception of men (95% CI: 1.340-2.457). Also, high risk perception of electromagnetic waves from cellular phones was observed when the subjects considered that they had more personal knowledge (OR: 1.416, 95% CI: 1.216-1.648), that the seriousness of the risk to future generations was high (OR: 1.410, 95% CI: 1.234-1.611), and their outrage for the occurrence of accidents related to electromagnetic waves was high (OR: 1.460, 95% CI: 1.264-1.686). The results of this study need to be sufficiently considered and reflected in designing the risk communication strategies and communication methods for the preventive measures and advice on electromagnetic waves from cellular phones. © 2014 Wiley Periodicals, Inc.

  2. The Hidden Risk Decisions in Waste Repository Regulation

    2001-01-01

    The move toward risk-informed, performance-based regulation of activities involving radioactive materials is becoming wide spread and broadly applied. While this approach may have some merit in specific applications in which there is a considerable body of experience, its strict application in regulation of geologic repositories for highly radioactive wastes may not be appropriate for this unproven and socially controversial technology. The U.S. Nuclear Regulatory Commission describes risk-informed, performance-based regulation as 'an approach in which risk insights, engineering analysis and judgement (eg. defense in depth), and performance history are used to (1) focus attention on the most important activities, (2) establish objective criteria based upon risk insights for evaluating performance, (3) develop measurable or calculable parameters for monitoring system and licensee performance, and (4) focus on the results as the primary basis for regulatory decision-making.' Both the risk-informed and performance-based elements of the approach are problematic when considering regulation of geologic repositories for highly radioactive wastes - an activity yet to be accomplished by any nation. In investigating potential sites for geologic repositories there will always be residual uncertainty in understanding the natural system and the events and processes that affect it. The more complex the natural system, the greater will be the uncertainty in both the data and the models used to describe the characteristics of the site's natural barriers, and the events and processes that could affect repository waste isolation. The engineered barriers also are subject to uncertainties that are important to the repository system. These uncertainties translate themselves into a range of probabilities that certain events or processes, detrimental to waste isolation, will occur. The uncertainties also translate to a range of consequences and magnitudes of consequences, should the

    The view of risk perception adopted in this paper focuses on how individuals define, and hence feel about, the outcomes of a risk issue. Perception of risk is seen as encompassing a variety of attributes of a risk issue including wider beliefs that permit a risk benefit trade-off. A survey of beliefs and attitudes of the general public toward the use of various energy systems (coal, oil, hydro, solar and nuclear energy) was carried out in Austria at a time of increasing concern with energy strategies and the controversy surrounding Austria's first nuclear energy plant. The results are analysed. In general, energy systems were found to be associated with only environmental risk; however, nuclear energy was an exception in that the public, whether in favour of nuclear energy or against, believed that it is also associated with psychological and physical risk. It was also found that the policy makers underestimated the public's negative feelings about the psychological risk dimension and their belief in its association with nuclear energy.

    We report data from the first representative national phone survey of Americans' perceptions about nanotechnology (N =1536). Public opinion about nanotechnology is in its infancy, and knowledge about it is quite limited. Yet, Americans' initial reaction to nanotechnology is thus far generally positive, probably rooted in a generally positive view of science overall. Survey respondents expected benefits of nanotechnology to be more prevalent than risks, and they reported feeling hopeful about nanotechnology rather than worried. Their most preferred potential benefit of nanotechnology is 'new and better ways to detect and treat human diseases,' and they identified 'losing personal privacy to tiny new surveillance devices' as the most important potential risk to avoid. The most discouraging aspect to the data is respondents' lack of trust in business leaders to minimize nanotechnology risks to human health. Overall, these data indicate that while Americans do not necessarily presume benefits and the absence of risks, their outlook is much more positive than not.

    It is well recognized that professional musicians are at risk of hearing damage due to the exposure to high sound pressure levels during music playing. However, it is important to recognize that the musicians' exposure may start early in the course of their training as students in the classroom and at home. Studies regarding sound exposure of music students and their hearing disorders are scarce and do not take into account important influencing variables. Therefore, this study aimed to describe sound level exposures of music students at different music styles, classes, and according to the instrument played. Further, this investigation attempted to analyze the perceptions of students in relation to exposure to loud music and consequent health risks, as well as to characterize preventive behaviors. The results showed that music students are exposed to high sound levels in the course of their academic activity. This exposure is potentiated by practice outside the school and other external activities. Differences were found between music style, instruments, and classes. Tinnitus, hyperacusis, diplacusis, and sound distortion were reported by the students. However, students were not entirely aware of the health risks related to exposure to high sound pressure levels. These findings reflect the importance of starting intervention in relation to noise risk reduction at an early stage, when musicians are commencing their activity as students.

    Full Text Available This study applies the “psychometric paradigm” of risk perception to the heavy mineral spill in the Sonora River (Mexico. A total of 241 inhabitants of the polluted area with a mean age of 46.3 years participated in the study, completing an interview questionnaire at the onset of the disaster. The results allow us to establish a profile of the 18 characteristics comprising the model and a multiple regression analysis shows that some characteristics of the dimensions of dread risk and unknown risk explain a percentage of the magnitude of the perceived risk. In addition, the behaviors recommended by the authorities were classified by the participants according to their estimated usefulness. Significant differences were observed. Avoiding contact with the water was considered the most effective, followed by recommendations on the use of the water, with actions related to the environment and how to avoid pollution being considered the least effective. In sum, the strategy deployed allows us to observe how the victims perceive the disaster and organize the behaviors proposed by the authorities.

    The present investigation is a cross-sectional, multi-national, quantitative, and quasi-experimental comparison of tourists' risk perceptions regarding different destinations throughout the past decade. Over 10,000 tourists to Norway from 89 different countries filled in a questionnaire rating the perceived risk for various destinations. Data were collected during 2004, 2010, 2011, 2012, 2013 and 2015 and allow for a comparison of perceived risk across time, place and nationality. Results show that while absolute risk judgments for different destinations fluctuate somewhat over the years, relative risk judgments remain constant. Findings also reveal a "home-is-safer-then-abroad-bias" with tourists consistently perceiving their home country among the safest destinations. The current investigation is rare because it looks at more than one destination at a time. Insights gained from the present findings diverge from what would have been concluded from employing case studies, that is, looking at one destination at a time. © 2016 The Authors.

    The risk of different treatment and disposal strategies of high level liquid radioactive waste from spent fuel reprocessing is estimated and compared. The conclusions obtained are that risk difference from these strategies is very small and high level liquid waste can be reduced to middle and low level waste, if the decontamination factor for 99 Tc is large enough, which is the largest risk contributor in the high level radioactive waste from spent fuel reprocessing. It is also shown that the risk of high level radioactive waste could be reduced by the technical strategy of combining partitioning and transmutation

    Given the importance of effective patient communication, findings about influences on risk perception in nonmedical domains need replication in medical domains. To examine whether numeracy influences risk perceptions when different information frames and number formats are used to present medication risks. The authors manipulated the frame and number format of risk information in a 3 (frame: positive, negative, combined) × 2 (number format: frequency, percentage) design. Participants from an Internet sample (N = 298), randomly assigned to condition, responded to a single, hypothetical scenario. The main effects and interactions of numeracy, framing, and number format on risk perception were measured. Participants given the positive frame perceived the medication as less risky than those given the negative frame. Mean risk perceptions for the combined frame fell between the positive and negative frames. Numeracy did not moderate these framing effects. Risk perceptions also varied by number format and numeracy, with less-numerate participants given risk information in a percentage format perceiving the medication as less risky than when given risk information in a frequency format; highly numerate participants perceived similar risks in both formats. The generalizability of the findings is limited due to the use of non-patients, presented a hypothetical scenario. Given the design, one cannot know whether observed differences would translate into clinically significant differences in patient behaviors. Frequency formats appear to increase risk perceptions over percentage formats for less-numerate respondents. Health communicators need to be aware that different formats generate different risk perceptions among patients varying in numeracy.

    People are exposed to different environmental risks, their manifestations harm people according to the magnitude, intensity and the number of people concerned. This subject is very ample, therefore we consider only two kinds of risks: the natural risks (especially earthquakes) that have always threatened humanity, and the industrial risks that characterise our modern society. We are interested in risk perception, stress and coping strategies in these two kinds of extreme situations. We concentrate our study on two Mexican events: an industrial explosion accident in 1984 and 1985 (big earthquake, both devastated big urban zones. The consequences were enormous at all levels: personal, psychological, social, political and economical. Facing risk situations people can have stress reactions when a sign of danger appears. According to Jean RIVOLIER (1994), these situations must not be confounded with banal events of everyday life. Stress in those cases is not the stress we confront everyday, so people have to apply other strategies to face she stress and the incidents of the kind of extreme situations. To tackle our subject we are going to review some concepts used in our study: stress, coping strategies and risk perception. (author)

    Full Text Available In October 2006 the European Civil Protection Exercise MESIMEX (Somma Vesuvio Mesimex – Major Emergency SIMulation Exercise on volcanic risk took place at Vesuvio, promoted by Campania Region and coordinated by the Italian Civil Protection Department. The exercise was focused on the preparedness phase for a major volcanic emergency in the area of Vesuvio. An evacuation of a sample of 1800 inhabitants from the Vesuvio Red Zone was also tested during the drill because the emergency plan ensures the complete evacuation of the population from the higher risk zone before the onset of the eruption. During that event a survey on volcanic risk perception was carried out on the evacuated population in order to compare the results with the ones coming from a previous similar survey, using the same questionnaire, carried out on a wider sample of residents in the Vesuvio Red Zone few months before MESIMEX exercise. The aim was to point out any differences in population’s attitude towards volcanic risk after having received detailed information on the emergency plan and on the hazards and risk related to the reactivation of Vesuvio, and experiencing the exercise. 463 questionnaires were distributed to the population evacuated from the 18 municipalities of the Red Zone and participating to the exercise. Main results in comparing data from MESIMEX survey with the Vesuvio previous one, put in evidence how the general level of Vesuvio residents’ trust remains quite low, indicating that a continuous and effective effort has to be done by both scientific community and Civil Protection Department.
