    1991-01-01

    Recognition of the pervasiveness of risk in everyday life in modern industrial society has elicited calls for greater efforts to protect individual and public health. Yet, it is increasingly clear that decisions to do so must often be made in the context of significant limits in the amounts of financial resources available for achieving that protection. Achieving risk-free work, residential, and community environments may be so expensive as to render a private business unit uncompetitive or as to divert resources from or prelude commencing with other governmental projects with equal or greater health benefit potential. Ethical low-level risk communication (LLRC) is something risk-generating entities are morally obligated to do. However, such communication also offers important opportunities for such entities to move toward achieving better balances between health and the costs of protecting it. In this paper, the authors elaborate on several features of an ethically ideal LLRC process, focusing on those with aspects they hope are not obvious or common knowledge. In discussing these features, they provide examples of conflicts between health risks and resource limits at the level of the individual private firm, the local community, or the national government, such that LLRC with the feature in question provides an opportunity for mitigating or at least clarifying the conflict in question

    Objectives: The use of ionising radiation in medical imaging is accompanied with occupational exposure which should be limited by optimised room design and safety instructions. These measures can however not prevent that workers are exposed to instantaneous dose rates, e.g. the residual exposure through shielding or the exposure of discharged nuclear medicine patients. The latter elements are often questioned by workers and detailed assessment should give more information about the impact on the individual radiation dose. Methods: Cumulated radiation exposure was measured in a university hospital during a period of 6 months by means of thermoluminescent dosimeters. Radiation exposure was measured at background locations and at locations where enhanced exposure levels are expected but where the impact on the individual exposure is unclear. Results: The results show a normal distribution of the cumulated background radiation level. No enhanced cumulated radiation exposure which significantly differs from this background level could be found during the operation of intra-oral apparatus, during ultrasonography procedures among nuclear medicine patients and at operator consoles of most CT-rooms. Conclusions: This 6 months survey offers useful information about occupational low level exposure in medical imaging and the findings can be useful in both risk communication and decision making.

    Low Level RF (LLRF) control system for storage ring of Shanghai Synchrotron Radiation Facility (SSRF) has been built by digital technology. The settings of parameters and the feedback loop status are carried out through the network communication interface, and the local oscillation and clock, which is the important component of the digital LLRF control system, are also configured through network communication. NIOS II processor was employed as a core to build the embedded system with a real-time operating system MicroC/OS-II, finally Lightweight TCP/IP (LwIP) was used to achieve the communication interface. The communication network is stable after a long-term operation. (authors)

    1993-01-01

    Using the limited human data plus the relationships derived from the laboratory, a leukemia risk model has been developed as well as a suggested model for other cancers in people exposed to low levels of radiation. Theoretical experimental and epidemiological evidence will be presented in an integrated stochastic model for projection of radiation-induced cancer risks

    Gloag, D.

    1980-01-01

    The difficulties involved in estimating risks from very low levels of radiation and the use of dose-response models for cancer incidence are discussed with reference to the third BEIR Committee report on the Effects on Populations of Exposure to low levels of Ionizing Radiation (1980). Cancer risk estimates derived from different epidemiological studies are reviewed. They include atom bomb survivors, medically irradiated groups and occupational groups. (36 references). (author)

  7. Development of a low-level waste risk methodology

    International Nuclear Information System (INIS)

    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

  8. Stochastic Model for Population Exposed to Low Level Risk

    Merkle, J.M.

    1996-01-01

    In this paper the stochastic model for population size, i.e. calculation of the number of deaths due to lethal stochastic health effects caused by the exposure to low level ionising radiation is presented. The model is defined for subpopulation with parameter (a, b) being fixed. Using the corresponding density function, it is possible to find all the quantities of interest by averaging over whole possible values for (a, l). All processes ar at first defined for one radionuclide, exposure pathway and the health effect under consideration. The results obtained in this paper are the basic quantities in the risk assessment, loss of life expectancy etc. The results presented in this paper are also applicable to the other sources of low level risk, not only the radiation risk

  9. Estimating population health risk from low-level environmental radon

    International Nuclear Information System (INIS)

    Fisher, D.R.

    1980-01-01

    Although incidence of respiratory cancer is directly related to inhalation of radon and radon daughters, the magnitude of the actual risk is uncertain for members of the general population exposed for long periods to low-level concentrations. Currently, any such estimate of the risk must rely on data obtained through previous studies of underground-miner populations. Several methods of risk analysis have resulted from these studies. Since the breathing atmospheres, smoking patterns, and physiology are different between miners and the general public, overestimates of lung cancer risk to the latter may have resulted. Strong evidence exists to support the theory of synergistic action between alpha radiation and other agents, and therefore a modified relative risk model was developed to predict lung cancer risks to the general public. The model considers latent period, observation period, age dependency, and inherent risks from smoking or geographical location. A test of the model showed excellent agreement with results of the study of Czechoslovakian uranium miners, for which the necessary time factors were available. The risk model was also used to predict lung cancer incidence among residents of homes on reclaimed Florida phosphate lands, and results of this analysis indicate that over the space of many years, the increased incidence of lung cancer due to elevated radon levels may be indisgtinguishable from those due to other causes

  10. Assessing risks from occupational exposure to low-level radiation

    Gilbert, E.S.

    1989-06-01

    Currently, several epidemiological studies of workers who have been exposed occupationally to radiation are being conducted. These include workers in the United States, Great Britain, and Canada, involved in the production of both defense materials and nuclear power. A major reason for conducting these studies is to evaluate possible adverse health effects that may have resulted because of the radiation exposure received. The general subject of health effects resulting from low levels of radiation, including these worker studies, has attracted the attention of various news media, and has been the subject of considerable controversy. These studies provide a good illustration of certain other aspects of the statistician's role; namely, communication and adequate subject matter knowledge. A competent technical job is not sufficient if these other aspects are not fulfilled

  11. Risk assessment and reliability for low level radioactive waste disposal

    International Nuclear Information System (INIS)

    Gregory, P.O.; Jones, G.A.

    1986-01-01

    The reliability of critical design features at low-level radioactive waste disposal facilities is a major concern in the licensing of these structures. To date, no systematic methodology has been adopted to evaluate the geotechnical reliability of Uranium Mill Tailings Remedial Action (UMTRA) disposal facilities currently being designed and/or constructed. This paper discusses and critiques the deterministic methods currently used to evaluate UMTRA reliability. Because deterministic methods may not be applicable in some cases because of the unusually long design life of UMTRA facilities, it is proposed that a probabilistic risk assessment-based methodology be used as a secondary method to aid in the evaluating of geotechnical reliability of critical items. Similar methodologies have proven successful in evaluating the reliability of a variety of conventional earth structures. In this paper, an ''acceptable'' level of risk for UMTRA facilities is developed, an evaluation method is presented, and two example applications of the proposed methodology are provided for a generic UMTRA disposal facility. The proposed technique is shown to be a simple method which might be used to aid in reliability evaluations on a selective basis. Finally, other possible applications and the limitations of the proposed methodology are discussed

    1984-04-01

    Any discussion of the risk of exposure to potentially-hazardous agents in the environment inevitably involves the question of whether the dose effect curve is of the threshold or linear, non-threshold type. A principal objective of this presentation is to show that the function is actually two separate relationships, each representing distinctly different functions with differing variables on the axes, and each characteristic of quite different functions with differing variables on the axes, and each characteristic of quite different disciplines (i.e., the threshold function, of Pharmacology, Toxicology and Medicine [PTM]; the linear, non-threshold function, of Public Health including safety and accident statistics [PHS]). It is shown that low-level exposure (LLE) to radiation falls clearly in the PHS category. A function for cell dose vs. the fraction of single cell quantal responses is characterized, which reflects the absolute and relative sensitivities of cells. Acceptance of this function would obviate any requirement for the use in Radiation Protection of the concepts of a standard radiation, Q, dose equivalent and rem. 9 references, 4 figures

  13. More on direct estimates of low-level radiation risks

    Rinsky, R.

    1982-01-01

    In an epidemiologic study of mortality at the Portsmouth Naval Shipyard (PNS), the National Institute for Occupational Safety and Health (NIOSH) found no evidence of excess deaths due to leukemia or other cancers among workers exposed to low levels of ionizing radiation. In a subsequent analysis, Bross and Driscoll identified excess lung cancer mortality in PNS workers with lifetime radiation dose of 1 rem or greater and with more than 15 years' latency since first radiation exposure. Although that observation may be important and is currently being examined through case-control analyses, it must be recognized that Bross and Driscoll extracted their observation from matrices of over 4,000 data cells apparently by recombination of innumerable possible permutations of dosage and latency intervals. For that reason, their finding can be regarded as no more than a suggestion for further study. It certainly does not represent a proper scientific conclusion. Bross and Driscoll's analysis illustrates the hazard of performing multiple statistical comparisons on complex data sets in the absence of a priori hypotheses

    This report was prepared for States, compact regions, and other interested parties to address two subjects related to transporting low-level radioactive waste to disposal facilities. One is the potential liabilities associated with low-level radioactive waste transportation from the perspective of States as hosts to low-level radioactive waste disposal facilities. The other is the radiological risks of low-level radioactive waste transportation for drivers, the public, and disposal facility workers.

    1991-01-01

    The average number of diagnostic x-ray procedures per year in the United States equals the total population and results in an annual collective effective dose equivalent of about 9 million person-rem. Possible deleterious effects include (a) genetic consequences, the risks of which can be assessed only from animal studies; (b) carcinogenesis, which can be assessed from survivors of nuclear bombings and patients exposed for medical reasons; and (c) effects on the developing embryo or fetus. For stochastic endpoints such as cancer and genetic anomalies, it is estimated that the current practice of radiology in the United States increases spontaneous frequency by less than 1%. No single procedure is likely to produce harm to the conceptus, but an accumulation of procedures in a pregnant woman could be hazardous during the sensitive period of 8-15 weeks after conception, with microcephaly and mental retardation the most likely deleterious effects. The balance of risk versus benefit in diagnostic radiology is heavily weighted toward benefit, but the risks are there, and constant efforts are needed to reduce radiation doses to the minimum necessary

    The treatment given by international organizations and associations to the problems of radiation exposures, and the recommendations and norms for calculating risks of low level radiation are analysed. It is shown that there are not zero risks for nuclear energy, and emphasis is given to the risks of natural radiation from environment. (M.C.K.) [pt

    This report is concerned with risk assessments for human populations receiving low level radiation doses; workers routinely exposed to radiation, Japanese victims of nuclear bombs, and the general public are all considered. Topics covered include risk estimates for cancer, mortality rates, risk estimates for nuclear site workers, and dosimetry

    The study on risk communication identifies the deficiencies concerning empirical and theoretical knowledge on objective radiation hazards of the acting personnel (managers, politicians, jurists, etc.) in administrations, governmental agencies, and business management. This is especially problematic with respect to emergency planning and estimations concerning the public behavior. The incident/accident information in Germany is discussed based on the legislative regulations revealing the controversial perception between industry, legislative and public interest. Further topics include the meandering of the modern safety semantics and the public opinion concerning catastrophic risk.

  20. Review of the controversy on risks from low levels of radiation

    International Nuclear Information System (INIS)

    Higson, D.

    2001-01-01

    The need for regulation of low levels of radiation exposure, and the estimation of risks from such exposures, are based on the assumption that risk is proportional to dose without a threshold, the 'linear no-threshold (LNT) hypothesis'. This assumption is not supported by scientific data. There is no clear evidence of harm from low levels of exposure, up to at least 20 mSv (acute dose) or total dose rates of at least 50 mSv per year. Even allowing for reasonable extrapolation from radiation levels at which harmful effects have been observed, the LNT assumption should not be used to estimate risks from doses less than 100 mSv. Laboratory and epidemiological evidence, and evolutionary expectations of biological effects from low level radiation, suggest that beneficial health effects (sometimes called 'radiation hormesis') are at least as likely as harmful effects from such exposures. Controversy on this matter strikes at the basis of radiation protection practice

    The resolution of radiation-attributable malignancies from the background of malignancies which are responsible for about 20% of all deaths in the Western world, presents a formidable challenge to epidemiological methods. Some of the major difficulties facing those with the task of estimating the risks associated with exposure to low level ionising radiation are discussed, particularly in the context of radiological protection. Some of the studies currently in progress are summarised and suggestions are made for other work which may help to contribute to a better understanding of the quantitative aspects of radiation risk assessment.

    The health effects of low-level ionizing radiation are yet unclear. As pointed out by Upton in his review (Upton, 1989), low-level ionizing radiation seems to have different biological effects from what high-level radiation has. If so, the hazard identification of ionizing radiation should he conducted separately for low- and high-level ionizing radiation; the hazard identification of low-level radiation is yet to be completed. What makes hazard identification of ionizing radiation difficult, particularly in the case of carcinogenic effect, is the difficulty in distinguishing radiation-induced cancer from other cancers with respect to clinicopathological features and molecular biological characteristics. Actually, it is suspected that radiation-induced carcinogenesis involves mechanisms not specific for radiation, such as oxidative stress. Excess risk per dose in medium-high dose ranges can be extrapolated to a low-dose range if dose-response can be described by the linear-non-threshold model. The cancer risk data of atomic-bomb survivors describes leukemia risk with a linear-quadratic (LQ) model and solid-cancer risk with linear non-threshold (LNT) model. The LQ model for leukemia and the LNT model for solid cancer correspond to the two-hit model and the one-hit model, respectively. Although the one-hit model is an unlikely dose-response for carcinogenesis, there is no convincing epidemiological evidence supporting the LQ model or non-threshold model for solid cancer. It should be pointed out, however, even if the true dose response is non-linear various noises involved in epidemiological data may mask the truth. In this paper, the potential contribution of epidemiological studies on nuclear workers and residents in high background radiation areas will be discussed. (author)

  3. Risk comparisons relevant to sea disposal of low level radioactive waste

    International Nuclear Information System (INIS)

    1993-11-01

    This document contains estimates of, and comparisons among, risks to human health posed by exposures to radionuclides, including those associated with low level radioactive wastes dumping at sea, and organic chemical contaminants resulting from seafood consumption. This study was conducted at the request of the Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (the London Convention 1972, formerly referred to as the London Dumping Convention) as a component of a review of the wider political, legal, economic and social aspects of sea dumping of radioactive wastes. The highest potential risks associated with seafood consumption are generally those resulting from exposures to naturally occurring radionuclides. In some representations, the potential risks associated with polychlorinated biphenyls (ΣPCB) and dieldrin in seafood are of the same order as those arising from naturally occurring radionuclides. The peak annual risks resulting from low level radioactive waste dumping at sea, assessed on any rational basis, are at least two orders of magnitude lower than those associated with the ingestion of common organic chemical contaminants in seafood. 47 refs, 4 figs, 13 tabs

    Some of the problems in determining the cancer risk of low-level radiation from studies of exposed groups are reviewed and applied to the study of Hanford workers by Mancuso, Stewart, and Kneale. Problems considered are statistical limitations, variation of cancer rates with geography and race, the ''healthy worker effect,'' calendar year and age variation of cancer mortality, choosing from long lists, use of proportional mortality rates, cigarette smoking-cancer correlations, use of averages to represent data distributions, ignoring other data, and correlations between radiation exposure and other factors that may cause cancer. The current status of studies of the Hanford workers is reviewed

    The phosphate deposits of central Florida contain levels of uranium and its daughter products 30-60 times greater than average soils. A case-control study was conducted to assess the risk of lung cancer associated with living on these phosphateic soils. Using the records of the state-wide Florida Cancer Data System to address this issue, all cases of lung cancer among Florida residents in 1981 were identified (n = 7049). Information was obtained regarding residence, age, sex, race, and smoking habits. Controls consisted of 6643 individuals with cancers of the colon or rectum. Residents of the central Florida phosphate region experienced a significant increase in lung cancer risk compared to other Florida residents (odds ratio (OR) = 1.4). Excess risks appeared concentrated among squamous cell cancer (OR = 1.6) and small cell cancer (OR = 1.6). When smoking habits as well as residential area was considered, no significant excess risk, associated with residence, was observed among nonsmokers or light smokers. Area residents smoking a pack or more per day experienced a 70% increase in lung cancer risk compared to individuals smoking a similar amount but living elsewhere. Highest risks were observed among persons with squamous cell cancer (OR = 2.1) and small cell cancer (OR = 2.5) who smoked more than 40 cigarettes a day. Results suggest exposure to low levels of ionizing radiation increases the lung cancer risk of residents of this area

  6. Who pays the bill: insuring against the risks from low level nuclear waste disposal

    International Nuclear Information System (INIS)

    Cohen, L.

    1981-01-01

    Long-range financial liability for low-level waste (LLW) activities is not currently assured. Part of the problem with finding an acceptable solution to liability has been a tendency to lump all long-term financial commitments, both risky and anticipated, together. It is suggested that only risks arising from unforeseen technical problems require special federal policies. Other long-term costs are more efficiently handled by traditional private insurance. Special policies are needed, however, for the unforeseen risks. The analysis concludes that state insurance of operators with federal reinsurance may be the most reasonable concept. Reinsurance levels should be set to balance federal information requirements, relative control of the three main parties over outcomes, and solvency requirements

    The risks for four cancers, leukemia, lymphopoietic cancers (LHC), lung cancer and mesothelioma, were studied in workers from shipyards involved in nuclear powered ship overhauls. The population represented a sample of all workers based on radiation dose at study termination. The final sample included 28,000 workers with ≥5.0 mSv, 10,462 workers with <5.0 mSv and 33,353 non-nuclear workers. Nuclear workers had lower mortality rates for leukemia and LHC than United States (US) white males but higher rates of lung cancer and a significant five-fold excess of mesothelioma. Dose-dependent analyses of risks in the high exposure group indicated that for each cancer the risk increased at exposures above 10.0 mSv. An internal comparison of workers with 50.0 mSv exposures to workers with exposures of 5.0-9.9 mSv indicated relative risks for leukemia of 2.41 (95% CI: 0.5, 23.8), for LHC, 2.94 (95% CI: 1.0, 12.0), for lung cancer, 1.26 (95% CI: 0.9, 1.9) and for mesothelioma, 1.61 (95% CI: 0.4, 9.7) for the higher exposure group. Except for LHC, these risks are not significant. However, the increasing risk with increasing exposure for these cancers, some of which are known to be related to radiation, suggests that low-level protracted exposures to gamma rays may be associated with these cancers. Other agents such as asbestos, which are common to shipyard work, may play a role especially in the risk of mesothelioma. Future follow up of the population would identify bounds on radiation risks for this population for comparison with similar risks estimated from other populations. (author)

  8. Critical review of the Hanford worker studies: cancer risk and low-level radiation

    1983-01-01

    Current estimates of cancer risks attributable to low-level radiation exposure are extrapolated from effects observed at higher doses. The inherent uncertainties in this approach make direct study of low-dose effects in human populations of great significance. Employees of the Hanford works in Richland, Washington constitute a large group of workers exposed to low-level radiation. The cancer mortality patterns in relation to radiation dose have been discussed by numerous investigators beginning with Mancuso, Stewart, and Kneale in 1977 and continuing to the present. These studies and their published critiques are summarized, with an effort to account for discrepant results by careful review of the analytic methods. Detailed consideration is given to exposure definition, classification of health outcomes, latency, the statistical methods employed, and selection biases. From this, it is concluded that (a) total cancers are unrelated to radiation exposure among these workers; (b) multiple myeloma and pancreatic cancer show a positive association with radiation dose based upon a few highly exposed cases; and (c) the relationship of radiosensitive cancers in the aggregate to radiation exposure is unresolved. Further study of the temporal course of exposure and latency in a classical cohort analysis of radiosensitive cancers might be informative, with special attention to the possibility of selection for jobs within the cohort

  9. Childhood leukaemia and low-level radiation - are we underestimating the risk?

    International Nuclear Information System (INIS)

    Wakeford, R.

    1996-01-01

    The Seascale childhood leukaemia 'cluster' can be interpreted as indicating that the risk of childhood leukaemia arising from low-level exposure to ionising radiation has been underestimated. Indeed, several variants of such an interpretation have been advanced. These include exposure to particular radionuclides, an underestimation of the radiation risk coefficient for childhood leukaemia, and the existence of a previously unrecognized risk of childhood leukaemia from the preconceptional irradiation of fathers. However, the scientific assessment of epidemiological associations is a complex matter, and such associations must be interpreted with caution. It would now seem most likely that the Seascale 'cluster' does not represent an unanticipated effect of the exposure to ionising radiation, but rather the effect of unusual population mixing generated by the Sellafield site which has produced an increase in the infection-based risk of childhood leukaemia. This episode in the history of epidemiological research provides a timely reminder of the need for great care in the interpretation-of novel statistical associations. (author)

    Full Text Available BackgroundLow levels of physical activity (PA are strongly associated with the development of metabolic syndrome (MetS and chronic diseases. However, few studies have examined this association in Koreans. The primary purpose of this study was to examine the associations between PA and MetS risks in Korean adults.MethodsA total of 1,016 Korean adults (494 males and 522 females participated in this study. PA levels were assessed using the International PA Questionnaire. MetS risk factors were determined using clinically established diagnostic criteria.ResultsCompared with the highest PA group, the group with the lowest level of PA was at greater risk of high triglyceride (TG in males (odds ratio [OR], 1.87; 95% confidence interval [CI], 1.07 to 3.24 and of hemoglobin A1c ≥5.5% in females (OR, 1.75; 95% CI, 1.00 to 3.04 after adjusting for age and body mass index. Compared with subjects who met the PA guidelines, those who did not meet the guidelines were more likely to have low high density lipoprotein cholesterol in both males (OR, 1.69; 95% CI, 1.11 to 2.58, and females (OR, 1.82; 95% CI, 1.20 to 2.77. Furthermore, those who did not meet the PA guidelines were at increased risk of high TG levels in males (OR, 1.69; 95% CI, 1.23 to 2.86 and abnormal fasting glucose (OR, 1.93; 95% CI, 1.17 to 3.20 and MetS (OR, 2.10; 95% CI, 1.15 to 3.84 in females.ConclusionIncreased levels of PA are significantly associated with a decreased risk of abnormal MetS components.

    At its Annual General Meeting in 2004, the Australasian Radiation Protection Society (A.R.P.S.) set up a working group to draft a statement of the Society's position on risks from low levels of exposure to ionizing radiation. The resulting position statement was adopted by the Society at its Annual General Meeting in 2005. Its salient features are as follows: First, there is insufficient evidence to establish a dose-effect relationship for doses that are less than a few tens of milli sieverts in a year. A linear extrapolation from higher dose levels should be assumed only for the purpose of applying regulatory controls. Secondly, estimates of collective dose arising from individual doses that are less than some tens of milli sieverts in a year should not be used to predict numbers of fatal cancers. Thirdly, the risk to an individual of doses significantly less than 100 micro sieverts in a year is so small, if it exists at all, that regulatory requirements to control exposure at this level are not warranted.

    Epidemiology is the study of disease in man. In evaluating radiation hazards, analytic studies have utilized the cohort type of investigation (where persons exposed and not exposed to radiation are followed forward in time for determination of disease experience) or case-control approaches (where persons with and without a specific disease are evaluated for previous exposure to radiation). Most radiation studies have evaluated cohorts (e.g., radiologists), although important case-control studies have been conducted (e.g., childhood leukemia as related to prenatal x ray). At its best, epidemiology is capable fo evaluating relative risks (RR) on the order of 1.4 (i.e., a 40% relative excess). However, the RRs of interest following low doses of radiation (1 rad) are on the order of 1.02-1.002. Thus, not much should be anticipated from direct observations at 1 rad, and indirect approaches must be taken to estimate low-dose effects. Such indirect approaches include evaluating 1) populations exposed to a range of doses, both low and high, where interpolation models can be reasonably applied to estimate low-dose effects; and 2) populations exposed to fractionated doses over a long period of time where the resulting dose-effect relationship theoretically should be linear and the estimation of low-level health effects facilitated

    When persons in the waste management industry have a conversation concerning matters of the industry, thoughts being communicated are understood among those in the industry. However, when persons in waste management communicate with those outside the industry, communication may suffer simply because of poor practices such as the use of jargon, euphemisms, acronyms, abbreviations, language usage, not knowing audience, and public perception. This paper deals with ways the waste management industry can communicate risk to the public without obfuscating issues. The waste management industry should feel obligated to communicate certain meanings within specific contexts and, then, if the context changes, should not put forth a new, more appropriate meaning to the language already used. Communication of the waste management industry does not have to be provisional. The authors suggest verbal risks in communicating risk can be reduced significantly or eliminated by following a few basic communication principles. The authors make suggestions and give examples of ways to improve communication with the general public by avoiding or reducing jargon, euphemisms, and acronyms; knowing the audience; avoiding presumptive knowledge held by the audience; and understanding public perception of waste management issues.

    The UK Department of the Environment (DoE) will perform independent post-closure safety assessment of proposals for the disposal of low-level radioactive wastes in engineered facilities in shallow ground. In this paper, the DoE assessment criteria, methodology and modelling capabilities are outlined; the general characteristics of the information required are discussed; and the specific information needs, as presently perceived, are identified. It is concluded that: most of the data that can be obtained by direct means is provided by site investigations and research now in hand, although there may be uncertainty due to sparse regional data; some parameters can only be obtained by, or with the assistance of subjective judgment; the process of data reduction is not straight forward and adequate time must be allowed for this if a comprehensive and defensible assessment is to be constructed

    The biological basis for risk assessment is discussed. The risks of carcinogenic effects, teratogenic effects, and genetic (heritable) effects are estimated to vary in proportion with the dose of radiation in the low-dose domain; however, the risks also appear to vary with the LET of the radiation, age at the time of irradiation, and other variables. Although the data suffice to place the risks in perspective with other hazards of modern life, further research to refine the reliability of the risk assessment is called for. (author)

    Evaluation of the potential health risk and individual exposure from a broad number of disposal alternatives is an important part of EPA's program to develop generally applicable environmental standards for the land disposal of low-level radioactive wastes (LLW). The Agency has completed an analysis of the potential population health risks and maximum individual exposures from ten disposal methods under three different hydrogeological and climatic settings. This paper briefly describes the general input and analysis procedures used in the risk assessment for LLW disposal and presents their preliminary results. Some important lessons learned from simulating LLW disposal under a large variety of methods and conditions are identified

    PRESTO, a computer code developed for the Environmental Protection Agency for the evaluation of possible health effects associated with shallow-land rad-waste burial areas, has been used to perform simulations for three such sites. Preliminary results for the 1000 y period following site closure suggest that shallow burial, at properly chosen sites, is indeed an appropriate disposal practice for low-level wastes. Periods of maximum risk to subject populations are also inferred

    Serious or lethal injuries that may result from the exposure of animals or human beings to ionizing radiations can be divided into two distinctly different categories, on the basis of whether the injury results only from failure of an entire vital organ, or stems from impairment of the function of a single cell. These two categories of injury are termed here organ effects, normally induced by non-stochastic processes, and single cell effects, normally induced by stochastic processes. This presentation is limited to low-level radiation exposure (LLR) since: (1) only with single hit kinetics does the average number of cell doses per cell in the exposed population essentially equal the number of cells dosed; (2) in excluding multihit all-or-none effects, the functions developed are essentially independent of the time rate at which the (instantaneously deposited) cell doses are laid down, and of considerations of repair of sub-effect injury; and (3) it makes little or no difference with LLR if the incidence of single cell effects is expressed in terms of exposed or surviving cells

  4. Spatial and temporal distribution of risks associated with low-level radioactive waste disposal

    1988-01-01

    The major purposes of this dissertation are to examine the economic tradeoffs which arise in the process of LLW disposal and to derive a framework within which the impact of these tradeoffs on LLW disposal policy can be analyzed. There are two distinct stages in the disposal of LLW - the transportation of the waste from sources to disposal sites and the disposal of the waste. The levels of costs and risks associated with these two stages depend on the number and location of disposal sites. Having more disposal sites results in lower transportation costs and risks but also in greater disposal costs and risks. The tradeoff between transportation costs and risks can also be viewed as a tradeoff between present and future risks. Therefore, an alteration in the spatial distribution of LLW disposal sites necessarily implies a change in the temporal distribution of risks. These tradeoffs are examined in this work through the use of a transportation model to which probabilistic radiation exposure constraints are added. Future (disposal) risks are discounted. The number and capacities of LLW disposal sites are varied in order to derive a series of system costs and corresponding expected cancers. This provides policy makers with a cost vs. cancers possibility function

    The objective was to provide a direct assessment of risks associated with exposures at the actual levels of interest. There are several epidemiological studies of populations that have received occupational exposure to radiation including workers at the Hanford nuclear facility. This population was used as a typical example to illustrate methods of analyzing such data. The Hanford data appear to demonstrate directly that risk estimates obtained by linear extrapolation from data on populations exposed at high levels are unlikely to underestimate risks by a factor greater than three. 15 refs

    Exposure to ionizing radiation is an established cause of leukemia in childhood ( -5 excess childhood leukemia cases per mSv for fetal exposure, around 1.5 x 10 -5 excess childhood leukemia cases per mSv for irradiation in early infancy, this latter risk coefficient reducing with advancing age at exposure . The closeness of the risk coefficients for exposure just before and after birth (derived from different sources of information) is reassuring. It is these coefficients that are used in assessing the risk of childhood leukemia due to, say, the operation of a nuclear facility, and such assessments have demonstrated that the risk due to normal operations will produce a very small number of extra cases, a 'signal' that will not be detectable above the unavoidable 'noise' of statistical fluctuations in background incidence rates . However, reports of childhood leukemia 'clusters' near certain nuclear installations in Britain have led to the accuracy of these assessments being challenged. (author)

    Exposure to ionising radiation can lead to a wide variety of health effects. Cancer is judged to be the main risk from radiation at low doses and low dose rates, and controlling this risk has been the main factor in developing radiation protection practice. Conventional paradigms of radiobiology and radiation carcinogenesis have served to guide extrapolations of epidemiological data on exposed human populations, so as to estimate risks at low doses and low dose rates, to other types of ionising radiation and to non-uniform exposures. These paradigms are founded on a century of experimental and theoretical studies, but nevertheless there remain many uncertainties. Major assumptions and simplifications have been introduced to achieve a practical system of additive doses (and implied risks) for radiation protection. Advancing epidemiological studies and experimental research continue to reduce uncertainties in some areas while, in others, they raise new challenges to the generality and applicability of the conventional paradigms.

    Full Text Available This study analyses the communication of the five major categories of risk (business, strategy, market and credit risk disclosure over the volatile 2007-2009 Global Financial Crisis (GFC time period in key South East Asian countries’ manufacturing listed companies. This study is important as it contributes to the literature by providing insights into the voluntary risk disclosure practices using sample countries with different economic scenarios. Key findings are that business risk is the most disclosed category and strategy risk is the least disclosed. Business and credit risk disclosure consistently increase over the three year period, while operating, market and strategy risk disclosure increase in 2008, but then decrease slightly in 2009. Statistical analysis reveals that country of incorporation and size help predict risk disclosure levels. The overall low disclosure levels (26-29% highlight the potential for far higher communication of key risk factors.

    1989-01-01

    This document describes a project to use epidemiological studies of workers in the nuclear industry to estimate the cancer risk associated with low-dose chronic exposure to ionizing radiation. The project aims both to improve the basis for radiation risk assessment and to test the validity of currently used models for the extrapolation of radiation risk. This report focusses on the former aim, and summarizes discussions at two meetings held in June 1988. One of these was a small working group consisting mainly of epidemiologists who had carried out studies of nuclear workers; the other included nominees of the nuclear industries of eleven countries as well as epidemiologists and radiation physicists and biologists. As a result of the meetings, efforts are underway to pool existing data and a feasibility study is addressing the possibility of an international collaborative study of unstudied groups of nuclear workers

    Verify the association between metabolic risk profile in students with different levels of cardiorespiratory fitness and body mass index, as well as the nutritional status of their parents. A cross-sectional study comprising 1.254 schoolchildren aged between seven and 17 years. The metabolic risk profile was calculated by summing the standardized values of high density lipoproteins and low density lipoproteins, triglycerides, glucose and systolic blood pressure. The parents' nutritional status was evaluated by self-reported weight and height data, for body mass index calculating. The body mass index of schoolchildren was classified as underweight/normal weight and overweight/obesity. The cardiorespiratory fitness was assessed by 9-minute running/walk test, being categorized as fit (good levels) and unfit (low levels). Data were analyzed using prevalence ratio values (PR). The data indicates a higher occurrence of developing metabolic risk in schoolchildren whose mother is obese (PR: 1.50; 95% CI: 1.01, 2.23), and even higher for those whose father and mother are obese (PR: 2, 79, 95% CI: 1.41; 5.51). Students who have low levels of cardiorespiratory fitness and overweight/obesity have higher occurrence of presenting metabolic risk profile (PR: 5.25; 95% CI: 3.31; 8.16). the occurrence of developing metabolic risk in schoolchildren increase when they have low levels of cardiorespiratory fitness and overweight/obesity, and the presence of parental obesity.

    For years, radiofrequency (RF) and microwave (MW) radiations have been applied in the modern world. The rapidly increasing use of cellular phones called recent attention to the possible health risks of RF/MW exposures. In 2011, a group of international experts organized by IARC (International Agency for Research on Cancer in Lyon) concluded that RF/MW radiations should be listed as a possible carcinogen (group 2B) for humans. Three meta-analyses of case-control studies have concluded that using cell phones for more than ten years was associated with an increase in the overall risk of developing a brain tumor. The Interphone Study, the largest health-related case-control international study of use of cell phones and head and neck tumors, showed no statistically significant increases in brain cancers related to higher amounts of cell phone use, but excess risk in a small subgroup of more heavily exposed users associated with latency and laterality was reported. So far, the published studies do not show that mobile phones could for sure increase the risk of cancer. This conclusion is based on the lack of a solid biological mechanism, and the fact that brain cancer rates are not going up significantly. However, all of the studies so far have weaknesses, which make it impossible to entirely rule out a risk. Mobile phones are still a new technology and there is little evidence about effects of long-term use. For this reason, bioelectromagnetic experts advise application of a precautionary resources. It suggests that if people want to use a cell phone, they can choose to minimize their exposure by keeping calls short and preferably using hand-held sets. It also advises discouraging children from making non essential calls as well as also keeping their calls short.

    The setting of any permissible radiation level or guide remains essentially an arbitrary procedure. Based on the radiation risk estimates derived, any lack of precision does not minimize either the need for setting public health policies nor the conclusion that such risks are extremely small when compared with those avialable of alternative options, and those normally accepted by society as the hazards of everyday life. When compared with the benefits that society has established as goals derived from the necessary activities of medical care and energy production, it is apparent that society must establish appropriate standards and seek appropriate controlling procedures which continue to assure that its needs are being met with the lowest possible risks. This implies continuing decision-making processes in which risk-benefit and cost-effectiveness assessments must be taken into account. Much of the practical information necessary for determination of radiation protection standards for public health policy is still lacking. It is now assumed that any exposure to radiaion at low levels of dose carries some risk of deleterious effects. However, how low this level may be, or the probability, or magnitude of the risk, still are not known. Radiation and the public health becomes a societal and political problem and not solely a scientific one. Our best scientific knowledge and our best scientific advice are essential for the protection of the public health, for the effective application of new technologies in medicine, and for guidance in the production of energy in industry. Unless man wishes to dispense with those activities which inevitably involve exposure to low levels of ionizing radiations, he must recognize that some degree of risk, however small, exists. In the evaluation of such risks from radiation, it is necessary to limit the radiation exposure to a level at which the risk is acceptable both to the individual and to society.

    2006-01-01

    Full text: Controversy continues in the radiation protection literature on whether or not ionizing radiation is harmful at low doses, with unresolved scientific uncertainty about effects below a few tens of millisieverts. To settle what regulatory controls (if any) should apply in this dose region, an assumption has to be made relating dose to the possibility of harm or benefit. The assumption made and the way it is applied can have far-reaching effects, not only on the scale of regulatory compliance required but also on public perception of risk, and therefore on the technological choices made by society. It is important therefore that decisions reached concerning the regulation of low doses of ionizing radiation derive from rational arguments and are perceived to have an ethical basis. It is also important that such decisions are neither portrayed nor perceived as resolving the scientific uncertainties: rather, they serve merely to facilitate the implementation of appropriate measures to ensure safety. At its Annual General Meeting in 2004, the Australasian Radiation Protection Society (ARPS) set up a working group to draft a statement of the Society's position on this matter. The resulting position statement was adopted by the Society at its Annual General Meeting on 14 November 2005. Its salient features are as follows: There is insufficient evidence to establish a dose-effect relationship for doses that are less than a few tens of millisieverts in a year. A linear extrapolation from higher dose levels should be assumed only for the purpose of applying regulatory controls; Estimates of collective dose arising from individual doses that are less than some tens of millisieverts in a year should not be used to predict numbers of fatal cancers; The risk to an individual of doses significantly less than 100 microsieverts in a year is so small, if it exists at all, that regulatory requirements to control exposure at this level are not warranted.

    1 - Description of program or function: PRESTO-II evaluates possible health effects from shallow-land and waste-disposal trenches. The model is intended to serve as a non- site-specific screening model for assessing radionuclide transport, ensuing exposure, and health impacts to a static local population fora 1000-year period following the end of disposal operations. Human exposure scenarios considered include normal releases (including leaching and operational spillage), human intrusion, and limited site farming or reclamation. Pathways and processes of transit from the trench to an individual or population include ground-water transport, overland flow, erosion, surface water dilution, suspension, atmospheric transport, deposition, inhalation, external exposure, and ingestion of contaminated beef, milk, crops, and water. Both population doses and individual doses, as well as doses to the intruder and farmer, may be calculated. Cumulative health effects in terms of cancer deaths are calculated for the population over the 1000-year period using a life-table approach developed by EPA (CCC-422/RADRISK). The DARTAB model is used in modified form to generate human health risk estimates from radionuclide concentrations and intake values. 2 - Method of solution: PRESTO-II tracks radionuclide transport through surface and subsurface pathways and human exposures through external exposure, inhalation, and ingestion with a resolution of 1 y. The methodology is mechanistic, and physical transport processes are modeled separately and in detail. PRESTO-II computes infiltration through the trench cap from experimentally determined permeability and hourly precipitation values. Watershed infiltration is determined using a parametric evapotranspiration equation requiring input values for several site variables. A finite element approach is used to compute trench water balance. 3 - Restrictions on the complexity of the problem: The PRESTO-II model is most appropriately used as a

In the 90's, the UNEP developed the APELL (Awareness and Preparedness for Emergency at Local Level) plan, a risk management methodology used by dangerous chemical facilities. The methodology comprises the commitment of both Government and the community located in the risk area in the development of the emergency plan. In the nuclear sector, there is no similar methodology developed so far. However, establishing a communication channel between the nuclear segment and the community is essential. In Brazil, the construction of Angra 3 and the RMB (Multi Purpose Reactor) project stand as nuclear initiatives that improve the importance of a good communication to the public. Security issues of these projects are natural sources of concernment to the public, which is aggravated by events such as the Fukushima disaster. Without an effective communication about what means the presence of nuclear plants and reactors in a specific area, the interested public will only have an alarmist vision of the subject, given by those against these facilities.

    Significant cancer risk for adults exposed to more than 100 millisieverts (10 REM) of ionizing radiation. More research on low-level ionizing radiation is needed in molecular and cellular mechanisms of injury and ongoing exposed populations. Implementation costs should be considered in regulating low-level ionizing radiation. Comparative risk assessment is a powerful tool for risk-based policy formation, and conflicting legal statutes should become harmonized for radiation regulation. More public dialog on low-level radiation is needed. A high level commission should evaluate radiation hazard control practices

    Effective food safety and food defense risk communication helps to inform consumers without causing panic and alarm. The Risk Communication Team of the Natl. Center for Food Protection and Defense has developed a list of 11 best practices recommended for effective risk communication. These practices, designed for a food defense crisis, are currently applied to food safety issues, since fortunately a food defense crisis has yet to occur. IFT examined the utility of these best practices and the limitations on their use during food safety and food defense crises by academics, trade associations, and the government. It was hypothesized that legal and business considerations as well as the nature of the event would determine the implementation of the best practices. Through the use of focus group meetings, it was discovered that there was a low level of awareness of the best practices. However, stakeholders practiced some aspects of the recommended practices. Participants felt some of the practices were related and could be consolidated. They also agreed that a food defense event will increase the urgency of the communication and include players not typically involved in food safety issues. The challenges reported by the stakeholders varied, but legal liability, as well as the impact their communications could have on an industry, were often cited. From the government perspective, their need to act within their authorities drove some of their actions with respect to communication. Determining the differences in communication limitations during food safety against food defense events can provide key information to further developing and refining risk communications and specific messages targeted for a food defense incident. Effective food safety and food defense risk communication helps to inform consumers without causing panic and alarm.

    1984-11-01

    This report is a user's manual for a partially completed code for risk assessment of a low-level waste shallow-land burial site, to be used in the licensing of burial sites. This code is intended as a tool to be used for considering nuclide transport mechanisms, including atmospheric, groundwater, erosion, and infiltration to an underlying aquifer. It also calculates doses to individuals and the population through direct exposure, inhalation, and ingestion. The methodology of the risk assessment is based primarily on the response surface method of uncertainty analysis. The parameters of a model for predicting dose commitment due to a release are treated as statistical variables in order to compute statistical distributions for various dose commitment contributions. The likelihood of a release is also accounted for by statistically evaluating the arithmetic product of the dose commitment distributions with the probability of release occurrence. An example is given using the atmospheric transport pathway as modeled by a code called BURYIT. The framework for using other release pathways is described in this manual. Information on parameter uncertainties, reference site characteristics, and probabilities of release events is included

    At its Annual General Meeting in 2004, the Australasian Radiation Protection Society (A.R.P.S.) set up a working group to draft a statement of the Society's position on risks from low levels of exposure to ionizing radiation. The resulting position statement was adopted by the Society at its Annual General Meeting in 2005. Its salient features are as follows: First, there is insufficient evidence to establish a dose-effect relationship for doses that are less than a few tens of milli sieverts in a year. A linear extrapolation from higher dose levels should be assumed only for the purpose of applying regulatory controls. Secondly, estimates of collective dose arising from individual doses that are less than some tens of milli sieverts in a year should not be used to predict numbers of fatal cancers. Thirdly, the risk to an individual of doses significantly less than 100 micro sieverts in a year is so small, if it exists at all, that regulatory requirements to control exposure at this level are not warranted.

    Risk assignments can be made to given practices involving exposure to radiation, because sufficient data are available for the effects of high-dose, low-LET radiation and because sufficient exists in the methods of extrapolation to low doses and low dose rates. The confidence in the extrapolations is based on the fact that the risk is not expected to be overestimated, using the assumptions made (as opposed to the possibility that the extrapolations represent an accurate estimate of the risk). These risk estimates have been applied to the selection of permissible exposure levels, to show that various amounts of radiation involve no greater risk to the worker than the risk expected in another industry that is generally considered safe. The setting of standards for protection from exposure to low levels of ionizing radiation is made by expert committees at the national and international levels who weigh social factors as well as scientific factors. Data on low-level effects may be applied when assigning a ''probability of causation'' to a certain exposure of radiation. This has become a prominent method for arriving at an equitable award for damages caused by such exposure. The generation of these tables requires as many (if not more) social and political considerations as does the setting up of protection criteria. It is impossible to extract a purely scientific conclusion solely from the protection standards and other legal decisions. Sufficient information exists on low-LET radiation that safety standards for exposure can be rationally (if not scientifically) agreed upon

    This paper 1) provides reasons why graphics should be effective aids to communicate risk; 2) reviews the use of visuals, especially graphical displays, to communicate risk; 3) discusses issues to consider when designing graphs to communicate risk; and 4) provides suggestions for future research. Key articles and materials were obtained from MEDLINE(R) and PsychInfo(R) databases, from reference article citations, and from discussion with experts in risk communication. Research has been devoted primarily to communicating risk magnitudes. Among the various graphical displays, the risk ladder appears to be a promising tool for communicating absolute and relative risks. Preliminary evidence suggests that people understand risk information presented in histograms and pie charts. Areas that need further attention include 1) applying theoretical models to the visual communication of risk, 2) testing which graphical displays can be applied best to different risk communication tasks (e.g., which graphs best convey absolute or relative risks), 3) communicating risk uncertainty, and 4) testing whether the lay public's perceptions and understanding of risk varies by graphical format and whether the addition of graphical displays improves comprehension substantially beyond numerical or narrative translations of risk and, if so, by how much. There is a need to ascertain the extent to which graphics and other visuals enhance the public's understanding of disease risk to facilitate decision-making and behavioral change processes. Nine suggestions are provided to help achieve these ends.

    The potential radiological impact of releases from a low-level radioactive waste (Category A waste) repository in Dessel, Belgium on the local fauna and flora was assessed under a reference scenario for gradual leaching. The potential impact situations for terrestrial and aquatic fauna and flora considered in this study were soil contamination due to irrigation with contaminated groundwater from a well at 70 m from the repository, contamination of the local wetlands receiving the highest radionuclide flux after migration through the aquifer and contamination of the local river receiving the highest radionuclide flux after migration through the aquifer. In addition, an exploratory study was carried out for biota residing in the groundwater. All impact assessments were performed using the Environmental Risk from Ionising Contaminants: Assessment and Management (ERICA) tool. For all scenarios considered, absorbed dose rates to biota were found to be well below the ERICA 10 μGy h -1 screening value. The highest dose rates were observed for the scenario where soil was irrigated with groundwater from the vicinity of the repository. For biota residing in the groundwater well, a few dose rates were slightly above the screening level but significantly below the dose rates at which the smallest effects are observed for those relevant species or groups of species. Given the conservative nature of the assessment, it can be concluded that manmade radionuclides deposited into the environment by the near surface disposal of category A waste at Dessel do not have a significant radiological impact to wildlife.

    An overview of the current situation in the United States and a look to the future of low-level waste management are presented. Current problems and challenges are discussed, such as: the need of additional disposal sites in the future; risks and costs involved in transport of low-level wastes; reduction of low-level waste volume through smelting, incineration, and storage for wastes containing nuclides with short half lives; development of a national policy for the management of low-level waste, and its implementation through a sensible system of regulations. Establishing a success with low-level waste management should provide the momentum and public confidence needed to continue on and to resolve the technical and politically more difficult low-level waste problems

    Federal regulations require nuclear facilities to be prepared for the risk communication aspects of a catastrophic emergency. Thus, all nuclear plants have provisions for a Joint Public Information Center (JPIC). The JPICs are designed to handle more than 300 media for 24 hours a day; to coordinate information among utility, federal, state, and local agencies; to provide spokespersons; etc. For a large-scale emergency, JPICs can work very well. However, some utilities - indeed, most companies - appear to have only two modes of emergency communication response: normal staff and JPIC. Experience has shown that normal staffing is inadequate to handle the risk communication response for media-intensive low-level emergencies and for the initial stages of an escalating emergency. It is clear that initial response will determine how well a company fares in its overall emergency response and in its long-term relations with the media and public. A solution to this risk communication challenge was developed by Cleveland Electric Illuminating Company's Perry Nuclear Plant - the Public Information Response Team. Using existing facilities and staff - only one of whom works regularly with the media - the Perry plant proactively manages its initial risk communication response

    1990-01-01

    Technology for detecting and understanding water quality problems and the impacts of activities on long-range groundwater quality has advanced considerably. In the past a technical solution was considered adequate but today one must consider a wide range of both technical and social factors in evaluating technical alternatives that are also acceptable social solutions. Policies developed and implemented with limited local participation generally are resisted and become ineffective if public cooperation is necessary for effective implementation. The public, the experts and the policymakers all must understand and appreciate the different perspectives present in risk policymaking. The typical model used to involve the public in policy decisions is a strategy described as the decide-announce-defend-approach. Much more acceptable to the public, but also more difficult to implement, is a strategy that calls for free flow of information within the community about the problem, policies and potential solutions. Communication about complex issues will be more successful if the communication is substantial; if it takes advantage of existing interpersonal networks and mass media; if it pays particular attention to existing audience knowledge, interest and behaviors; and if it clearly targets messages to various segments of the audience

    This paper attempts to provide a broad context for consideration of appropriate risk communication approaches. It examines the basis of public concerns and in particular the non-risk dimensions. The latter are so important in any risk decision that means of communication which can deal with them are required which extend beyond understanding how to present risk estimates. These means relate to (a) the decision processes themselves and the extent to which they provide for involvement of the public in decisions, (b) the communication skills of experts, and (c) the robustness of the risk information which is available.

    . Despite of the reported increased morbidity of haematopoietic and lymphatic neoplasms, it was not possible to confirm the causal link of the morbidity with exposure to MW radiation. Therefore, it is concluded that the epidemiologic evidences still falls short of their strength and consistency required to come to a reasonable conclusion that MW can cause human cancer and thus, this radiation should be classified in group 3 (unclassifiable as to carcinogenicity in humans) of the IARC classification of human carcinogens The possibility of development of functional abnormalities of certain physiological systems (e.g. nervous, cardiovascular, immune and/or humoral) in subjects exposed to RF/MW radiations requires further studies in view of steadily increasing use of mobile phone systems. In general, health risks of MP use are underestimated and accepted, while risks from base stations are overestimated by the public. Therefore, an improved risk communication, as well as further studies of the risks, are required. (author)

    It is known that the normal incidence of cancer in human populations is increased by exposure to moderately high doses of ionizing radiation. At background radiation levels or at radiation levels which are 100 times greater, the potential health risks are considered to be directly proportional to the total accumulated dose of radiation. Some of the uncertainties associated with this assumption and with the accepted risk estimates have been critically reviewed in this document. The general scientific consensus at present suggests that the accepted risk estimates may exaggerate the actual risk of low levels of sparsely ionizing radiations (beta-, gamma- or X-rays) somewhat but are unlikely to overestimate the actual risks of densely ionizing radiations (fast neutrons, alpha-particles). At the maximum permissible levels of exposure for radiation workers in nuclear power stations, the potential health hazards in terms of life expectancy would be comparable to those encountered in transportation and public utilities or in the construction industry. At the average radiation exposures received by these workers in practice, the potential health hazards are similar to those associated with safe categories of industries. Uranium mining remains a relativly hazardous occupation. In terms of absolute numbers, the genetic hazards, which are less well established, are thought to be smaller than the carcinogenic hazards of radiation when only the first generation is considered but to be of the same order of magnitude as the carcinogenic hazards when the total number of induced genetic disorders is summed over all generations

    The health effect of low-level ionizing radiation is yet unclear. As pointed out by Upton in his review (Upton, 1989), low-level ionizing radiation seems to have different biological effects from what high-level radiation has. Its evaluation requires epidemiological studies of scale-large cohorts (ICRP 99, 2005) such of atomic bomb survivors and nuclear workers. Epidemiological studies in high-background radiation (HBR) areas are also expected to make a significant contribution toward this end. Among several HBR areas in the world, Yangjiang, Guangdong Province in China, Karunagappally in Kerala State of India, Manawalakurichi and Koodankulam in Tamil Nadu of India, and Ramsar in Iran are important areas where epidemiological studies are possible, because of their relatively high background radiation levels and large population sizes.

    A pressing question in military medical research is the nature and degree of effects on the human brain from occupational repeated exposure to low-level explosive blast, but reliable and effective means to objectively measure such effects remain elusive. In survey results, headache, difficulty sleeping, irritability, cognitive impairment, and a variety of other symptoms consistent with post-concussive syndrome have been reported by those exposed to blast and there was positive correlation between degree of blast exposure and degree of symptomology, but an important goal is to obtain more objective evidence of an effect than self-report alone. This review reflects recent efforts to measure and evaluate such hypothesized effects and current recommendations for ongoing study. Optimal measures are likely those with sensitivity and specificity to systemic effects in mild neurotrauma, that have minimal to no volitional component, and that can be sampled relatively quickly with minimal intrusion in prospective, observational field studies during routine training with explosives. An understanding of an association between parameters of exposure to repeated low-level blast and negative neurologic effects would support the evaluation of clinical implications and development of protective equipment and surveillance protocols where warranted. At present, low-level blast exposure surveillance measurements do not exist as a systematic record for any professional community.

    Since the enactment of NEPA and other environmental legislation, the concept of `risk communication` has expanded from simply providing citizens with scientific information about risk to exploring ways of making risk information genuinely meaningful to the public and facilitating public involvement in the very processes whereby risk is analyzed and managed. Contemporary risk communication efforts attempt to find more effective ways of conveying increasingly complex risk information and to develop more democratic and proactive approaches to community involvement, in particular to ensuring the participation of diverse populations in risk decisions. Although considerable progress has been made in a relatively short time, risk communication researchers and practitioners currently face a number of challenges in a time of high expectations, low trust, and low budgets.

    Full Text Available Environmental analysts are often hampered in communicating the risks of environmental contaminants due to the myriad of regulatory requirements that are applicable. The use of a qualitative, risk-based control banding strategy for assessment and control of potential environmental contaminants provides a standardized approach to improve risk communication. Presented is a model that provides an effective means for determining standardized responses and controls for common environmental issues based on the level of risk. The model is designed for integration within an occupational health and safety management system to provide a multidisciplinary environmental and occupational risk management approach. This environmental model, which utilizes multidisciplinary control banding strategies for delineating risk, complements the existing Risk Level Based Management System, a proven method in a highly regulated facility for occupational health and safety. A simplified environmental risk matrix is presented that is stratified over four risk levels. Examples of qualitative environmental control banding strategies are presented as they apply to United States regulations for construction, research activities, facility maintenance, and spill remediation that affect air, water, soil, and waste disposal. This approach offers a standardized risk communication language for multidisciplinary issues that will improve communications within and between environmental health and safety professionals, workers, and management.

    1989-01-01

    Communication of risk and risk decisions has always been a matter of great difficulty. A great deal of research has been devoted to improving either the understanding of people's perception of risk or people's understanding of risk itself. These achievements have, however, either failed or the results have not been properly introduced in risk communication. At least this is what can be deduced from recent very heated discussions of risk decisions concerning chemical industry in Denmark. It might thus be that the focus of our interest should be changed from improving already existing methods of risk analysis to improving our understanding of why risk communication very often fails - and fails with very severe consequences. In Denmark a working party set up by the Minister for the Environment has just concluded its work on these matters. This main problem seems to be that the authorities' very one-dimensional perception of risk simply do not reflect the concern of the public and that of many politicians. If this is true the problem is not just a matter of communication but a much more fundamental one which parameters should be introduced in risk evaluation in order to satisfy the need of the public - and how this can be done.

    Estimators for calculating the risk of cancer and genetic disorders induced by exposure to ionizing radiation have been recommended by the US National Academy of Sciences Committee on the Biological Effects of Ionizing Radiations, the UN Scientific Committee on the Effects of Atomic Radiation, and the International Committee on Radiological Protection. These groups have also considered the risks of somatic effects other than cancer. The US National Council on Radiation Protection and Measurements has discussed risk estimate procedures for radiation-induced health effects. The recommendations of these national and international advisory committees are summarized and compared in this report. Based on this review, two procedures for risk estimation are presented for use in radiological assessments performed by the US Department of Energy under the National Environmental Policy Act of 1969 (NEPA). In the first procedure, age- and sex-averaged risk estimators calculated with US average demographic statistics would be used with estimates of radiation dose to calculate the projected risk of cancer and genetic disorders that would result from the operation being reviewed under NEPA. If more site-specific risk estimators are needed, and the demographic information is available, a second procedure is described that would involve direct calculation of the risk estimators using recommended risk-rate factors. The computer program REPCAL has been written to perform this calculation and is described in this report. 25 references, 16 tables

    1994-01-01

    Terms such as 'risk', 'hazardous incident', and 'communication' have become major catchwords in discussions about present-day problems, and may be reduced to a common denominator: disaster. Such an association, however, is inappropriate, as the concept indicated by the term 'risk' for instance covers a wide scale of possible danger. Even the term 'hazardous incident' describes events or conditions that are very different in terms of possible danger, let alone disastrous effects. The discrepancy to be observed between the facts and the public perception usually is due to the fact that people have little insight into the complex of problems involved, and to insufficient communication between the world of experts and the general public. The contributions to this publication present information and discuss a variety of solution sets to improve the communication problems in the context of the problem area of 'risk - hazardous incident - communication'.

    Major advances have occurred over the last 20 years about how to effectively communicate risk information and warnings to the public. These lessons have been hard won. Knowledge has mounted on the finding from social scientific studies of risk communication failures, successes and those which fell somewhere in between. Moreover, the last 2 decades have borne witness to the brith, cultivation, and blossoming of information sharing between those physical scientists who discover new information about risk and those communcation scientists who trace its diffusion and then measure pbulic reaction.

    It is difficult to develop an objective approach to risks and effects of a hazardous incident that would be acceptable to the community at large. It is a matter of fact that there is great dissimilarity in the way various social groups perceive and define the risks of a particular technology, or the effects of hazardous incidents, sometimes they have even contrary opinions. Hence, open communication is seriously hampered, which in turn aggravates the problems encountered in this context. This second volume of the publication dealing with the problem area of 'risk - hazardous incident - communication' is intended to reveal patterns of the recurrent process which impedes communication, and to bridge the gaps between the various 'styles' of risk perception and definition.

    2003-04-01

    Increased lung and nasal cancer risks have been reported in several cohorts of nickel refinery workers, but in more than 90% of the nickel-exposed workers that have been studied there is little, if any evidence of excess risk. This investigation utilizes human exposure measurements, animal data from cancer bioassays of three nickel compounds, and a mechanistic theory of nickel carcinogenesis to reconcile the disparities in lung cancer risk among nickel-exposed workers. Animal data and mechanistic theory suggest that the apparent absence of risk in workers with low nickel exposures is due to threshold-like responses in lung tumor incidence (oxidic nickel), tumor promotion (soluble nickel), and genetic damage (sulfidic nickel). When animal-based lung cancer dose-response functions for these compounds are extrapolated to humans, taking into account interspecies differences in deposition and clearance, differences in particle size distributions, and human work activity patterns, the predicted risks at occupational exposures are remarkably similar to those observed in nickel-exposed workers. This provides support for using the animal-based dose-response functions to estimate occupational exposure limits, which are found to be comparable to those in current use.

    Full Text Available The association between sex hormone-binding globulin (SHBG and arterial stiffness in women is not conclusive. In addition, obesity might also be involved in the relationship between SHBG and atherosclerosis. The aim of this study was to determine the relationship between SHBG and arterial stiffness in association with central obesity in women. This cross-sectional study included 381 women who participated in the health checkup programs in one hospital. The brachial-ankle pulse wave velocity (baPWV was measured as a marker for arterial stiffness. A negative correlation was observed between SHBG levels and baPWV (rho = −0.281. The relationship was significant even after adjusting for potential confounders (beta = −0.087 in fully adjusted model. After considering the interaction between central obesity and SHBG levels, the significant association was evident only in obese women (P for interaction = 0.025. Adjustment for a 10-year atherosclerotic cardiovascular disease (ASCVD risk scores, instead of each cardiovascular risk factor individually, did not affect the significance of the relationship between SHBG levels and baPWV. Serum levels of SHBG were negatively associated with arterial stiffness independent of cardiovascular risk factors or 10-year ASCVD risk scores in Korean women. The relationship may be potentiated by central obesity.

  11. CONSIDERATIONS IN RISK COMMUNICATION: A DIGEST OF RISK COMMUNICATION AS A RISK MANAGEMENT TOOL

    Risk communication is the process of informing people about hazards. Like all communication, communicating risk is a two-way exchange in which you inform the target community about possible hazards, but also gather information about those affected by the risk. The purpose of risk...

  12. Radiation in complex exposure situations. Assessing health risks at low levels from concomitant exposures to radiation and chemicals

    International Nuclear Information System (INIS)

    Hornhardt, S.; Jung, T.; Burkart, W.

    2000-01-01

    Health effects from exposures to ionizing radiation are in general the result of complex multi-step reaction chains involving changes and responses on the level of molecules, cells, tissues and organisms. In environmental low dose exposure situations ionizing radiation only contributes a small fraction to the life-long attack on DNA by other exogenous and endogenous genotoxins. Nevertheless, efforts to assess and quantify deleterious effects at low exposure levels are directed mainly towards radiation as a single isolated agent, and rarely towards the concomitant presence of other natural and anthropogenic toxicants. Only these combined exposures may lead to observable health risk effects. In addition they might differ from those expected from simple addition of the individual risks due to interaction. The existing data base on combined effects is rudimentary, mainly descriptive and rarely covers exposure ranges large enough to make direct inferences to present day low dose exposure situations. Therefore, any risk assessment will have to consider the question whether combined effects, i.e. interaction between two or more agents will influence the health outcome from specific exposure situations in such a way that predictions derived from simple standard exposure situations would have to be revised. In view of the multitude of possible interactions between the large number of potentially harmful agents in the human environment, descriptive approaches will have to be supplemented by the use of mechanistic models for critical health endpoints such as cancer. Agents will have to be grouped depending on their physical or chemical mode of action at the molecular and cellular level, to generalize and predict the outcome of combined exposures at low exposure levels and the possibility of interactions.

    Risk communication is a growing specialty field in communication that draws from well-established principles of sociology and psychology. It is a new way to communicate with potentially hostile audiences about sensitive environmental, safety, and health issues they face. This paper explains the most important principles of risk communication and discusses audience analyses, perceptions of risk (outrage factors), and risk comparisons. These principles are applied to a risk communication issue in Malhuevo, a fictitious Arizona community

    Final disposal of low level wastes has been carried out for 15 years on the shallow land disposal of the Manche in the north west of France. Final participant in the nuclear energy cycle, ANDRA has set up a new waste management system from the production center (organization of the waste collection) to the disposal site including the setting up of a transport network, the development of assessment, additional conditioning, interim storage, the management of the disposal center, records of the location and characteristics of the disposed wastes, site selection surveys for future disposals and a public information Department. 80 000 waste packages representing a volume of 20 000 m 3 are thus managed and disposed of each year on the shallow land disposal. The disposal of low level wastes is carried out according to their category and activity level: - in tumuli for very low level wastes, - in monoliths, a concrete structure, of the packaging does not provide enough protection against radioactivity [fr

    The overall research objective was to establish new levels of information about how people, groups, and communities respond to low dose radiation exposure. This is basic research into the social psychology of individual, group, and community responses to radiation exposures. The results of this research are directed to improving risk communication and public participation in management of environmental problems resulting from low dose radiation

  16. Report from risk communication practice

    National Institute of Radiological Sciences (NIRS) set up a phone consulting service early after Fukushima Nuclear Power Plant Accident and inquiries to the service attained over 14,000 at August end, 2011. This paper describes the process, present state and future view of the risk communication based on experiences through the service. The communication is classified in 3 stages of consensus/care in peacetime, crisis, and consensus/care post disaster. The first one contains the consensus of atomic power policy and provision of its information; the second, of evacuation/indoor evacuation and indication of restricted water and food intake; and the third, communication for changes and standard of radiation related matters. Initial inquiries to the NIRS service were many concerning examinations of radiation screening, decontamination and internal exposure, from inside and outside of Fukushima Prefecture, suggesting the concern had been spread to remote area from the Prefecture. Then, the time needed per inquiry/consultation prolonged, implying the wish for solving the concern. The risk communication and consideration for realizing radiation risk at peacetime might have rather unrealistic, which was thought to be the major cause of problems at crisis. In addition, interpretation of various values relating to radiation had been apparently different from expert to expert, and findings by radiation effects and rules of radiation protection had been confusedly understood, which probably influenced on people's correct understanding. However, it is conceivably a fruit of taken risk communication that the past understanding ''radiation, unseeable, is terrible'' has changed to the current understanding ''protection can be done through risk assessment of radiation, measurable''. Hereafter, important are the practical use of various numerical values officially informed and realization of dose through exposure routes, and dispatch of their integrated information to lessen the

    International Nuclear Information System (INIS)

    1997-04-01

    This manual reports the results of a risk characterization of Category D inactive liquid low-level radioactive waste (LLLW) at the Oak Ridge National Laboratory (ORNL). The risk characterization is required by the Federal Facility Agreement between the Department of Energy-Oak Ridge Operations Office, the Environmental Protection Agency-Region IV, and the Tennessee Department of Environment and Conservation. The intent of the risk characterization is to determine relative priorities for assessment and remediation. When the scores for all tanks had been weighted and summed, the tanks were ranked in descending order on the basis of their total scores. The highest possible score for a tank is 30. The descending order represents the recommended priorities for evaluation: the higher the score, the higher the priority for evaluation

  18. Communicating Risk to Program Managers

    Science.gov (United States)

    Shivers, C. Herbert

    2005-01-01

    Program Managers (PM) can protect program resources and improve chances of success by anticipating, understanding and managing risks. Understanding the range of potential risks helps one to avoid or manage the risks. A PM must choose which risks to accept to reduce fire fighting, must meet the expectations of stakeholders consistently, and avoid falling into costly "black holes" that may open. A good risk management process provides the PM more confidence to seize opportunities save money, meet schedule, even improve relationships with people important to the program. Evidence of managing risk and sound internal controls can mean better support from superiors for the program by building a trust and reputation from being on top of issues. Risk managers have an obligation to provide the PM with the best information possible to allow the benefits to be realized (Small Business Consortium, 2004). The Institute for Chartered Accountants in England and Wales sees very important benefits for companies in providing better information about what they do to assess and manage key business risks. Such information will: a) provide practical forward-looking information; b) reduce the cost of capital; c) encourage better risk management; and d) improve accountability for stewardship, investor protection and the usefulness of financial reporting. We are particularly convinced that enhanced risk reporting will help listed companies obtain capital at the lowest possible cost (The Institute of Chartered Accountants in England &Wales, June 2002). Risk managers can take a significant role in quantifying the success of their department and communicating those figures to executive (program) management levels while pushing for a broader risk management role. Overall, risk managers must show that risk management work matters in the most crucial place-the bottom line- as they prove risk management can be a profit center (Sullivan, 2004).

  19. Communicating the risk from radon

    Fisher, A.; McClelland, G.H.; Schulze, W.D.; Doyle, J.K.

    1991-01-01

    A prominent television station developed a special series of newscasts and public service announcements about radon. This was combined with their advertising of the availability of reduced-price radon test kits in a local supermarket chain. The large number of test kits sold was a success from a marketing perspective, but not from a public health perspective - especially because of the very small share of high readings that were mitigated. In contrast, a study of housing sales showed a much higher testing rate and corresponding mitigation when risk communication accompanied the housing transaction, rather than being directed toward the general public. This paper examined the relative effectiveness of these alternative approaches to radon risk communication, emphasizing the implications for developing and implementing radon programs

    The Nevada Test Site (NTS) is a major receiver of low-level radioactive waste (LLW) for disposal. Currently, all LLW received at NTS is shipped by truck. The trucks use highway routes to NTS that pass through the Las Vegas Valley and over Hoover Dam, which is a concern of local stakeholder groups in the State of Nevada. Rail service offers the opportunity to reduce transportation risks and costs, according to the Waste Management Programmatic Environmental Impact Statement (WM-PEIS). However, NTS and some DOE LLW generator sites are not served with direct rail service so intermodal transport is under consideration. Intermodal transport involves transport via two modes, in this case truck and rail, from the generator sites to NTS. LLW shipping containers would be transferred between trucks and railcars at intermodal transfer points near the LLW generator sites, NTS, or both. An Environmental Assessment (EA)for Intermodal Transportation of Low-Level Radioactive Waste to the Nevada Test Site (referred to as the NTSIntermodal -M) has been prepared to determine whether there are environmental impacts to alterations to the current truck routing or use of intermodal facilities within the State of Nevada. However, an analysis of the potential impacts outside the State of Nevada are not addressed in the NTS Intermodal EA. This study examines the rest of the transportation network between LLW generator sites and the NTS and evaluates the costs, risks, and feasibility of integrating intermodal shipments into the LLW transportation system. This study evaluates alternative transportation system configurations for NTS approved and potential generators based on complex-wide LLW load information. Technical judgments relative to the availability of DOE LLW generators to ship from their sites by rail were developed. Public and worker risk and life-cycle cost components are quantified. The study identifies and evaluates alternative scenarios that increase the use of rail (intermodal

    Cox, N.D.; Atwood, C.L.

    1985-12-01

    This report is a user's manual for a package of computer programs and data files to be used for probabilistic risk assessment of shallow-land burial of low-level radioactive waste. The nuclide transport pathways modeled are an unsaturated groundwater column, an aquifer, and the atmosphere. An individual or the population receives a dose commitment through shine, inhalation, ingestion, direct exposure, and/or a puncture wound. The methodology of risk assessment is based on the response surface method of uncertainty analysis. The parameters of the model for predicting dose commitment due to a release are treated as statistical variables, in order to compute statistical distributions for various contributions to the dose commitment. The likelihood of a release is similarly treated as a statistical variable. Uncertainty distributions are obtained both for the dose commitment and for the corresponding risk. Plots and printouts are produced to aid in comparing the importance of various release scenarios and in assessing the total risk of a set of scenarios. The entire methodology is illustrated by an example. Information is included on parameter uncertainties, reference site characteristics, and probabilities of release events

  4. Risk evaluation of embedded, single-walled liquid low-level waste piping at Oak Ridge National Laboratory. ESD Publication 4315

    International Nuclear Information System (INIS)

    1994-10-01

    Four categories of liquid low-level radioactive waste (LLLW) systems are defined in the Federal Facility Agreement (FFA) for the Oak Ridge Reservation (ORR). Categories A and B are new and fully compliant existing systems, respectively: Category C is singly contained and must be removed from service, and Category D is inactive. The FFA requires that secondary containment and leak detection be provided for all Category A and B piping in the LLLW System at Oak Ridge National Laboratory (ORNL); however, as noted in the D2 revision of the secondary containment design demonstration report (DOE 1994), some sections of single-walled embedded piping in Category B underground vaults at three ORNL facilities do not meet this requirement. A risk evaluation was performed in order compare the potential radiation dose to a member of the public that could result from a postulated leak in the single-walled pipes with projected radiation exposure to the workers who would modify the piping to meet FFA requirements. The risk to human health from replacing segments of embedded, single-walled piping in the LLW system is higher than the risk of leaving the piping as it is

    The objective of this project is to conduct basic research on how people receive, evaluate, and form positions on scientific information and its relationship to low-dose radiation exposure. There are three major areas of study in our research program. First is the development of theories, frameworks and concepts essential to guiding data collection and analysis. The second area is a program of experimental studies on risk perception, evaluation of science information, and the structure of individual positions regarding low-dose exposures. Third is the community-level studies to examine and record how the social conditions, under which science communications take place, influence the development of attitudes and opinions about: low-dose exposures, the available management options, control of radiation risks, and preferences for program and policy goals

    A key success of the decommissioning effort at the National Aeronautics and Space Administration's (NASA's) Plum Brook Reactor Facility (PBRF) has been the public outreach program. The approach has been based on risk communications rather than a public relations approach. As a result it has kept the public feeling more involved in the process. It ensures they have the information needed to understand the project and its goals, and to make recommendations. All this is done so that NASA can better plan and execute the necessary work without delays or suprises.

    Despite the last few decades’ devotion to deliberative methods in risk communication, many studies point to how important challenges arise when citizens are engaged in public dialogue. Since the era of enlightenment public dialogue has occupied a position as a normative ideal for political...... governance. But ideals are social constructions that have a tendency to direct attention away from underlying conflicts. The concept of dialogue is no exception, and exemplified by the Danish solution to dealing with public scepticism in relation to technological controversies, the internationally acclaimed...

  8. Environmental risk communication as an educational process

    Science.gov (United States)

    Schottenfeld, Faith

    The purpose of this study was to explore the dynamics of the environmental risk communication process. The goal was to look at the totality of the process by examining the different components: entry to communication (what brings people into the process), maintenance of communication (behaviors of participants, pathways to successful risk communication, barriers to successful risk communication, characteristics of the dialogue) and outcomes of risk communication (what has been learned, what moves the process to social action, what else can come of the process). Interviews and critical incidents were used to explore the experiences of risk communicators in four different practice settings: academia, industry/trade groups, community-based organizations and government. Twenty-four people completed critical incident stories and sixteen participated in in-depth interviews. Data were coded and analyzed for themes. Findings illustrated that successful risk communication results from a deliberative, or purposeful process. This process includes a systematic approach to identifying and inviting people to participate, while considering specific motivating factors that affect participation. Risk communication is maintained by creating and nurturing structured forums for dialogue by acknowledging the varying perspectives of the people who participate and the contextual settings of environmental risks. The result of effective dialogue may range from increased knowledge, to transformative learning to social action and policy change. The researcher recommended that a multi-disciplinary team including risk communicators, adult educators and scientists can work most effectively to plan, implement and evaluate a risk communication process.

    The paper presents a risk-based approach for rapid prioritization of low-level liquid radioactive waste underground storage tanks (LLLW USTs), for possible interim corrective measures and/or ultimate closure. The ranking of LLLW USTs is needed to ensure that tanks with the greatest potential for adverse impact on the environment and human health receive top priority for further evaluation and remediation. Wastes from the LLLW USTs at Oak Ridge National Laboratory were pumped out when the tanks were removed from service. The residual liquids and sludge contain a mixture of radionuclides and chemicals. Contaminants of concern that were identified in the liquid phase of the inactive LLLW USTs include the radionuclides 90 Sr, 137 Cs, and 233 U and the chemicals carbon tetrachloride, trichloroethane, tetrachloroethene, methyl ethyl ketone, mercury, lead, and chromium. The risk-based approach for prioritization of the LLLW USTs is based upon three major criteria: (1) leaking characteristics of the tank, (2) location of the tanks, and (3) toxic potential of the tank contents. Leaking characteristics of LLLW USTs will aid in establishing the potential for the release of contaminants to environmental media. In this study, only the liquid phase was assumed to be released to the environment. Scoring criteria for release potential of LLLW USTs was determined after consideration of the magnitude of any known leaks and the tank type for those that are not known to leak

    High levels of arsenic exposure have been associated with increases in cardiovascular disease risk. However, studies of arsenic's effects at lower exposure levels are limited and few prospective studies exist in the United States using long-term arsenic exposure biomarkers. We conducted a prospective analysis of the association between toenail arsenic and cardiovascular disease mortality using longitudinal data collected on 3939 participants in the New Hampshire Skin Cancer Study. Using Cox proportional hazard models adjusted for potential confounders, we estimated hazard ratios and 95% confidence intervals associated with the risk of death from any cardiovascular disease, ischemic heart disease, and stroke, in relation to natural-log transformed toenail arsenic concentrations. In this US population, although we observed no overall association, arsenic exposure measured from toenail clipping samples was related to an increased risk of ischemic heart disease mortality among long-term smokers (as reported at baseline), with increased hazard ratios among individuals with ≥ 31 total smoking years (HR: 1.52, 95% CI: 1.02, 2.27), ≥ 30 pack-years (HR: 1.66, 95% CI: 1.12, 2.45), and among current smokers (HR: 1.69, 95% CI: 1.04, 2.75). These results are consistent with evidence from more highly exposed populations suggesting a synergistic relationship between arsenic exposure and smoking on health outcomes and support a role for lower-level arsenic exposure in ischemic heart disease mortality. - Highlights: • Arsenic (As) has been associated with increased cardiovascular disease (CVD) risk. • Little is known about CVD effects at lower levels of As exposure common in the US. • Few have investigated the joint effects of As and smoking on CVD in US adults. • We examine chronic low-level As exposure and smoking in relation to CVD mortality. • Arsenic exposure may increase ischemic heart disease mortality among smokers in US

The intent of the risk characterization is to determine relative priorities for assessment and remediation. A total of 55 FFA Category D inactive LLLW tanks are discussed in this manual. Of the 39 tanks at ORNL that have been accepted into the Environmental Restoration (ER) Program, all have been sampled for preliminary characterization, except for 5 tanks that were found to be empty plus I that was found not to exist. The remaining 16 tanks are in the Waste Management (WM) Program. Twelve were sampled for preliminary characterization, and four were found empty. Each sampled tank was scored on a scale of I to 5 on the basis of three criteria: (1) leak characteristics, (2) location, and (3) toxicological characteristics of residual sludges and liquids. Each criterion was assigned a weighing factor based on perceived importance. The criterion score multiplied by the weighting factor equaled the tank's total score for that criterion. The three weighted criterion scores for each tank were then summed for a total score for that tank. When the scores for all tanks had been weighted and summed, the tanks were ranked in descending order on the basis of their total scores. The highest possible score for a tank is 30. The descending rank order represents the recommended priorities for evaluation: the higher the score, the higher the priority for evaluation. Of the 54 tanks sampled in the risk characterization, 23 tanks scored 16 or higher, 11 scored between 10 and 15, 5 scored between 4 and 9, and 15 scored 3 or less

    Managers in the nuclear industry and other potentially hazardous industries face tough but not insurmountable challenges when communicating about the risks for which they are responsible. Two types of information offer hints about successful risk communication: research within and across several disciplines and documentation of case studies. This presentation synthesizes research results and case study experience to define effective risk communication and suggests steps toward achieving it

  16. Low level radiation: biological effects

    International Nuclear Information System (INIS)

    Loken, M.K.

    1983-01-01

    It is imperative that physicians and scientists using radiations in health care delivery continue to assess the benefits derived, vs. potential risk, to patients and radiation workers being exposed to radiation in its various forms as part of our health delivery system. Insofar as possible we should assure our patients and ourselves that the benefits outweigh the potential hazards involved. Inferences as to the possible biological effects of low level radiation are generally based on extrapolations from those effects observed and measured following acute exposures to considerably higher doses of radiation. Thus, in order to shed light on the question of the possible biological effects of low level radiation, a wide variety of studies have been carried out using cells in culture and various species of plant and animal life. This manuscript makes reference to some of those studies with indications as to how and why the studies were done and the conclusions that might be drawn there from. In addition reference is made to the handling of this information by scientists, by environmentalists, and by the news media. Unfortunately, in many instances the public has been misled by what has been said and/or written. It is hoped that this presentation will provide an understandable and reasonable perspective on the various appropriate uses of radiation in our lives and how such uses do provide significant improvement in our health and in our quality of life

  17. Significance and basic patterns of risk communication

    The philosophically coloured paper on the aspects of risk communication patterns in society shows that debates about risks are governed by a number of stereotype characters representing the individualist and manager type, bureaucracy and law-and-order type, ego-centered embarrassment activist, and fundamentalist. Every risk-relevant group in the study tries to push forward its own interests. Risk communication is understood as a process of social dealing. (HP) [de

  18. On independence in risk communication

    International Nuclear Information System (INIS)

    Lacronique, J. F.

    2006-01-01

    The term 'independence' is a common key word used by almost all stake holders in the field of nuclear safety regulation. The intention is to persuade the public that it can have more confidence and trust in the persons in charge, if their competence and judgment cannot be altered by any kind of political issue or personal interest. However, it is possible to discuss the reality of this claimed quality: how is it possible to verify that the organization that claim 'independence' really respect it? National expertise Institutions can show that they are independent from the industry, but can they claim total independence from the government? NGO have build a large part of their constituency on 'independence' from industry and governments, but are they independent from the ideological forces -sometimes very powerful - that support them? How can we achieve to make this noble word really meaningful? We will show through different examples, that 'independence' is by definition a fragile and versatile challenge, rather than a durable label. It has to be refreshed regularly and thoroughly. Risk communication, in that context, must respect principles which will build independence as a solid asset, and keep a certain distance with mere marketing purposes or candid wishful thinking

  19. Guidelines for designing messages in risk communication

    Risk Communication Study Team (hereafter called RC team) has designed messages for risk communication based on the analysis of the local residents' opinions which were expressed in several questionnaire surveys. The messages are described in a side format (Power Point format) every single content. This report provides basic guidelines for making messages that are used for risk communication, and does not include concrete messages which RC team designed. The RC team has already published the report entitled 'Information materials for risk communication' (JNC TN8450 2003-008) separately, and it gives the concrete messages. This report shows general cautions and checklists in designing messages, comments on the messages from outside risk communication experts, and opinions from local residents. (author)

    The paper attempts to summarize the major findings of the psychological and sociological literature on trust and credibility, and to apply these findings to the specific arena of risk communication. A few guidelines for risk communication that appear appropriate for the social and institutional context in which the risk debate takes place are presented. The case studies of credibility of nuclear energy, biotechnology, medicine, and aviation are discussed. (DG)

    In the field of atomic energy and radiation utilization, radiation risk is considered as one of the social uneasy factors. About the perception of risks, there is a gap between experts and general public (non-experts). It is said that the general public tends to be going to judge risk from intuitive fear and a visible concrete instance whereas the experts judge it scientifically. A company, an administration or experts should disclose relating information about the risks and communicate interactively with the stakeholders to find the way to solve the problem with thinking together. This process is called 'risk communication'. The role of the expert is important on enforcement of risk communication. They should be required to explain the information on the risks with plain words to help stakeholders understand the risks properly. The Japan Health Physics Society (JHPS) is the largest academic society for radiation protection professionals in Japan, and one of its missions is supposed to convey accurate and trustworthy information about the radiation risk to the general public. The expert group on risk communication of ionizing radiation of the JHPS has worked for the purpose of summarizing the fundamental matters on radiation risk communication. 'Lecture on risk communication for the members of the JHPS.' which has been up on the JHPS web-site, and the symposium of 'For better understanding of radiation risk.' are a part of the activities. The expert group proposes that the JHPS should enlighten the members continuously for being interested in and practicing risk communication of radiation. (author)

  2. Emotional tone and argumentation in risk communication

    Directory of Open Access Journals (Sweden)

    Denis Hilton

    2008-01-01

    Full Text Available In this paper I explore how the evolution of emotional expression and co-operative planning in humans may inform the way they communicate about risks, and what implication this may have for models of rationality in risk communication. In particular, I focus on aspects of human language that enable successful co-ordination around shared tasks that involve the management of uncertainty by a group. I distinguish between performative (action-oriented and constative (description-oriented aspects of human communication, and argue that the human logical vocabulary of conditionals, quantifiers and probability expressions often conveys pragmatic signals that implicitly encourage or discourage a course of action that is under discussion. I review some studies that illustrate this perspective by highlighting the role of emotional undertone in risk communication and management, and show how it differs from existing models of risk communication and decision-making.

    It is recently, that is, in and after the 1980s that socio-scientific approaches began to be made to studies on `risk`. It started to be made clear that the progress of the scientific technology does not necessarily bring about good news to man, and obvious estrangement has begun to appear between scientific evaluation and social evaluation of risk. The subject of risk communication (RC) study is to tackle a proposition whether the estrangement will continue to exist as estrangement or the estrangement can be made smaller by any means. This paper explains the recent trend of the study. For example, as for how each individual thinks about risk, that is, the risk perception, a new framework is trially being constructed by introduction of the quantitative method using psychometrics. A duty of RC is to serve to bridge the gap between scientific technology and society which are controlled by values which are incompatible with each other. Therefore, RC will be more and more important. 15 refs., 1 fig., 2 tabs.

    1997-01-01

    The principles and practices of risk communication in the petroleum industry in Alberta were presented. In order to effectively communicate about risk, three challenges must be met: (1) the representatives of the oil company must accept the legitimacy of the public's assessment of risk, (2) the communication needs to be two-way, and (3) the risk-related issues in the community must be addressed through a process of participatory decision-making where the public is accepted as a legitimate partner. For the oil and gas companies, failing to undertake effective risk communication can lead to many problems, such as difficulties in obtaining regulatory approvals, production delays, high legal fees, and loss of public trust

    This report summarizes the risk communication activities of Nuclear Fuel Cycle Engineering Laboratories conducted by mainly Risk Communication Study Office. To gain trust and understanding of the local community for nuclear energy, a 'Risk Communication Study Team' was set up at former Tokai Works, Japan Nuclear Cycle Development Institute (JNC) in January, 2001. When former JNC and former Japan Atomic Energy Research Institute (JAERI) were merged in October, 2005, the Team was changed to 'Risk Communication Study Office' in Nuclear Fuel Cycle Engineering Laboratories. This report shows the risk communication activities implemented from January, 2001 to March 2007. The activities are classified into three categories: research and study on risk communication, message design and development of information transmission tools, and implementation of risk communication. As for the research and study, we investigated the risk communication about nuclear energy in Western countries. As for the message design, we made messages under our basic policy of showing information clearly that residents want to know. We have prepared about 300 messages in slide format (Microsoft Power Point) and compiled them in a report. More easy-to understand messages were created from the viewpoint of the residents by working in collaboration with local residents, not making messages by ourselves. As for the development of information transmission tools, we have been developing a portal website, 'Risk Information Navigator', which provides information about risks that exist in daily life such as traffic accidents and natural disasters, as well as risk information on nuclear technology. We produced videos and environmental panels as information transmission tools, and made poster panels, clear holder, Karuta' (Japanese card game), and so on in the collaboration work with residents. As a practice of risk communication, we have been carrying out Cycle Friendly Talk', which is direct dialogue within

    Japan Nuclear Cycle Development Institute (JNC), Tokai Works set up the Risk Communication Study Team in January, 2001 to promote mutual understanding between the local residents and JNC. The Team has studied risk communication from various viewpoints and developed new methods of public relations which are useful for the local residents' risk perception toward nuclear issues. We aim to develop more effective risk communication which promotes a better mutual understanding of the local residents, by providing the risk information of the nuclear fuel facilities such a Reprocessing Plant and other research and development facilities. We explain the development process of audio visual information materials which describe our actual activities and devices for the risk management in nuclear fuel facilities, and our discussion through the effectiveness measurement.

    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.

    As people become more sensitive to health and environmental issues, effective communication of workplace risks becomes more important for both employers and their employees. Risk communication must be given in a clear, simple format that addresses the individual employee's work environment. It must also be provided in a manner that indicates to the employees that the company cares about their safety. Failure to provide this information may result in ineffective communication and reduced company credibility. By using events and issues from the employees every day life, these issues can be effectively managed. (author)

    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.

    Radiological specialists from Nagasaki University have served on the medical relief team organized at Fukushima Medical University Hospital (Fukushima City) ever since the accident at the Fukushima Dai-ichi nuclear power plant. Furthermore, we have conducted the radiation crisis communication efforts by spreading correct information on the health effects of radiation as 'advisors on radiation health risk control'. Nagasaki University has been assisting the reconstruction efforts of Kawauchi Village in Fukushima Prefecture, which was the first village to declare that residents could safely return to their homes because radiation doses were found to be at comparatively low levels. In April 2013, Nagasaki University and the Kawauchi government office concluded an agreement concerning comprehensive cooperation toward reconstruction of the village. As a result, we established a satellite facility of the university in the village. In conclusion, training of specialists who can take responsibility for long-term risk communication regarding the health effects of radiation as well as crisis communication in the initial phase of the accident is an essential component of all such recovery efforts. Establishment of a training system for such specialists will be very important both for Japan and other countries worldwide. (authors)

    Risk communication, especially to the general public and end users of plant protection products, is an important challenge. Currently, much of the risk communication the general public receives is via the popular press, and risk managers face the challenge of presenting their decisions...... and their scientific basis to the general public in an understandable way. Therefore, we decided to explore the obstacles in risk communication, as done by expert risk assessors and managers. Using the discourse analysis framework and readability tests, we studied perspectives of 3 stakeholder groups......—regulators, industry representatives, and academics across Europe. We conducted 30 confidential interviews (10 participants in each group), with part of the interview guide focused on communication of pesticide risk to the general public and the ideas experts in the field of risk assessment and management hold...

    Many health-related decisions require choosing between two options, each with risks and benefits. When presented with such tradeoffs, people often make choices that fail to align with scientific evidence or with their own values. This study tested whether risk communication and values clarification methods could help parents and guardians make evidence-based, values-congruent decisions about children's influenza vaccinations. In 2013-2014 we conducted an online 2×2 factorial experiment in which a diverse sample of U.S. parents and guardians (n = 407) were randomly assigned to view either standard information about influenza vaccines or risk communication using absolute and incremental risk formats. Participants were then either presented or not presented with an interactive values clarification interface with constrained sliders and dynamic visual feedback. Participants randomized to the risk communication condition combined with the values clarification interface were more likely to indicate intentions to vaccinate (β = 2.10, t(399) = 2.63, p communication and values clarification methods may contribute to increased vaccination intentions, which may, in turn, predict vaccination status if logistical barriers are also addressed. © 2015 Society for Risk Analysis.

  7. Risk communication in environmental restoration programs

    Energy Technology Data Exchange (ETDEWEB)

    Bradbury, J.A.

    1993-04-01

    The author advocates adoption of a convergence model in place of the traditional source-receiver model of communication for communicating with members of the public who have a stake in remediation of a nearby site. The source-receiver model conceives of communication as the transmission of a message from a risk management agency (sender) to a target audience of the public (receivers). The underlying theme is that the sender intends to change the perception of the receiver of either the issue or the sender of information. The theme may be appropriate for health campaigns which seek to change public behavior; however, the author draws on her experience at a DOE site undergoing remediation to illustrate why the convergence model is more appropriate in the context of cleanup. This alternative model focuses on the Latin derivation of communication as sharing or making common to many, i.e., as involving a relationship between participants who engage in a process of communication. The focus appears to be consistent with recently issued DOE policy that calls for involving the public in identifying issues and problems and in formulating and evaluating decision alternatives in cleanup. By emphasizing context, process and participants, as opposed to senders and receivers, the model identifies key issues to address in facilitating consensus concerning the risks of cleanup. Similarities between the institutional context of DOE and DOD suggest that a convergence model may also prove to be an appropriate conceptual foundation for risk communication at contaminated DOD sites.

  8. Recommendations for citizen-oriented risk communication

    Fertmann, R.

    2005-01-01

    The purpose of recommendations for citizen-oriented risk communication should be to provide ''banisters'' which leave the players their freedom of action and allow them to adapt communicative structures to the situation at hand. Uncertainty and controversial issues at the levels of information, participation and assessment are identified as potential stumbling blocks in risk communication. The experiences gained in Hamburg shed a light on a diversity of processes in risk communication, which the present paper proceeds to evaluate. One of its essential recommendations is to have dialogic processes develop into forms of participation. A guide on risk communication which was formulated in the USA has been adapted to conditions as they prevail in Germany. The adapted version is more practically oriented than the rules of the EPA or the more recent CDC recommendations. Suitable success criteria include a fair procedure, a common baseline of what is known and not known, the acceptance of different assessment criteria, and the exchange of the pros and cons of different options

    1990-01-01

    Those responsible for state and local radon programs often express frustration about the small share of homes that have been tested for radon, and the small share of those with high readings that have been mitigated. There are now a number of completed studies that have examined how well alternative ways of communicating about radon risk have accomplished the goals of motivating appropriate testing and mitigation. This paper summarizes the research results that are most crucial for planning and implementing effective radon risk communication programs. We identify six reasons why people do not respond to radon as a serious threat and provide some remedies suggested by radon studies

    International Nuclear Information System (INIS)

    Gallina, C.O.

    1992-01-01

    As far as the general public is concerned, scientists can forget about risk perception and risk acceptance. These worthy scientific goals only confuse the one single important issue - how people perceive and accept technology. Risk is rarely accepted in the abstract by the general public. Because people would rather be assured than educated, risk can only be presented within the framework of what people will accept when they accept the technology, which (among other things) produces the aforementioned risk itself. It is in this technological environment that effective risk communication becomes extremely complex. To understand the risk, the public must understand the technology - a formidable task in itself, but one that becomes even more difficult when two additional factors are included: media attention and political influence

They show that - contrary to a current popular belief - acceptance problems are not attributable to information deficits: such problems are caused rather by the fact that risks are perceived differently by the various groups in science, industry, politics and the larger public. Nevertheless, improved information about technology may help to find acceptable compromises and, thus, to prevent social conflicts to erupt over technology and to geopardize the basic political consensus.

    Developing an effective communication strategy about different food hazards depends not only on technical risk assessments (for example related to health or the environment) but must also take into account consumer perceptions and preferences. In addition, consumers make decisions about food choices

    A low level photoneutron detection equipment has been developed. The photoneutrons produced by interaction of 226 Ra gamma quanta and deutron (D) target are detected with n-n discrimination detector made up of 3 He proportional counter array. The D-content information in the target can be obtained from the measured photoneutron counts. The equipment developed is mainly used for nondestructive D-content measurement of D-devices

  16. Radiogenic health effects: communicating risks to the general public

    Strzelczyk, Jadwiga

    1999-01-01

    Harmful effects of prolonged radiation exposures were recognized early on following the discovery of X-rays by W.C. Roentgen in 1895. The type and severity of radiogenic effects are functions of a number of factors, radiation quality and quantity, chemical toxicity, and radiosensitivity of irradiated tissues being the most significant ones. Currently, there are several human registries for radiogenic cancers. Atomic bomb and nuclear test survivors, and populations exposed to medical irradiation constitute the largest study cohorts. Two general types of radiogenic effects have emerged from these registries: prompt and delayed. While the effects of acute exposures are very well documented, investigations of the effects of low-level exposures require the use of mathematical models. Communicating the risks of lower-level chronic radiation exposures to the general public remains a challenging task. The most effective approaches include clear interpretation and placing radiation risks in perspective: risks versus benefits, and comparisons with risks carried by common activities in which we all engage.

  17. Communication in reducing facility siting risk

    Bisconti, A.S.

    1992-01-01

    Today, social considerations are as important as technical ones in siting new nuclear facilities. Siting any industrial facility has become extremely difficult in this era of not in my backyard (NIMBY). Even if NIMBY does not arise locally, well-organized national opposition groups can be counted on to step in to fan the flames, especially when the industrial facility has to do with anything nuclear. It is now generally recognized that the greatest risk of failure for new nuclear facilities is not technical but social. Applying lessons gained from past experience and social science research can help reduce that risk. From these lessons, six principles for public interaction and communication stand out: (1) create goodwill now; (2) involve the community early; (3) establish the need; (4) communicate controls, not risk; (5) avoid jargon; (6) understand your public

  20. A nationwide low-level waste management system

    International Nuclear Information System (INIS)

    1985-01-01

    The National Governors' Association, in conjunction with the Department of Energy's National Low-Level Waste Management Program, invited various representatives of states, regions, and federal agencies to comment on their perceptions of what major features would constitute a nationwide low-level waste management system. Three meetings were conducted and this report summarizes results of those meetings. The Low-Level Radioactive Waste Policy Act of 1980 placed primary responsibility on the states for disposal of low-level waste. Although initial efforts of states have been directed toward establishing compacts, it is evident that a successful long term system requires significant cooperation and communication among states, regions, federal agencies, and Congress

    We promote introduction of risk-awareness in the design and operation of communications networks and services. This means explicit and systematic consideration of uncertainties related to improper behavior of the web of interdependent networks and the resulting consequences for individuals, companies and a society as a whole. Central activities are the recognition of events challenging dependability together with the assessment of their probabilities and impacts. While recognizing the complex technical, business and societal issues, we employ an overall risk framing approach containing risk assessment, response and monitoring. Our paradigm gathers topics that are currently dispersed in various fields of network activities. We review the current state of risk-related activities in networks, identify deficiencies and challenges, and suggest techniques, procedures, and metrics towards higher risk-awareness.

  5. Low level waste shipment accident lessons learned

    On October 1, 1994 a shipment of low-level waste from the Fernald Environmental Management Project, Fernald, Ohio, was involved in an accident near Rolla, Missouri. The accident did not result in the release of any radioactive material. The accident did generate important lessons learned primarily in the areas of driver and emergency response communications. The shipment was comprised of an International Standards Organization (ISO) container on a standard flatbed trailer. The accident caused the low-level waste package to separate from the trailer and come to rest on its top in the median. The impact of the container with the pavement and median inflicted relatively minor damage to the container. The damage was not substantial enough to cause failure of container integrity. The success of the package is attributable to the container design and the packaging procedures used at the Fernald Environmental Management Project for low-level waste shipments. Although the container survived the initial wreck, is was nearly breached when the first responders attempted to open the ISO container. Even though the container was clearly marked and the shipment documentation was technically correct, this information did not identify that the ISO container was the primary containment for the waste. The lessons learned from this accident have DOE complex wide applicability. This paper is intended to describe the accident, subsequent emergency response operations, and the lessons learned from this incident

    Effectively communicating the risks associated with emerging zoonotic diseases remains an important challenge. Drawing on research into the psychological effects of metaphoric framing, we explore the conditions under which exposure to the "nation as a body" metaphor influences perceived risk susceptibility, behavioral intentions, and policy support in the context of Zika virus. In a between-subjects experiment, 354 U.S. adults were randomly assigned to one of four experimental conditions as part of a 2 (severity message: high vs. low) × 2 (U.S. framing: metaphoric vs. literal) design. Results revealed an interaction effect such that metaphoric (vs. literal) framing increased perceived risk susceptibility in the high-severity condition only. Further analyses revealed that perceived risk susceptibility and negative affect mediated the path between the two-way interaction and policy support and behavioral intentions regarding Zika prevention. Overall, these findings complement prior work on the influence of metaphoric framing on risk perceptions, while offering practical insights for risk communicators seeking to communicate about Zika and other zoonotic diseases. © 2018 Society for Risk Analysis.

    The incidences of cardiovascular risk factors such as obesity and diabetes are rising in many Asian populations. In April 2000, a 5-year territory-wide health promotion campaign supported by Li Ka Shing Foundation was launched in Hong Kong by the Health InfoWorld of Hospital Authority. From the general working class, 4,832 Chinese people were randomly recruited into this campaign. There were 2,370 men (49.0%) and 2,462 women (51.0%; median age = 43.0 years, range = 17-83 years). Of these, 37.5% were obese (BMI > or = 25 kg/m2 or waist circumference > or = 80 cm in women and > or = 90 cm in men), 22.3% had hypertension, 11.6% were smokers, 31.0% had hypercholesterolaemia (total cholesterol > or = 5.2 mmol/l), 2.2% had diabetes, and 0.7% had a past history of cardiovascular disease. There were 1,338 participants (27.7%) who had 2 or more risk factors (more men than women: 36.9% vs. 18.9%, p Hong Kong people. Massive public education is an important and essential, although it may not be self-sufficient, factor to reduce the socioeconomic impacts of this epidemic.

    Arsenic in drinking water impacts health. Highest levels of arsenic have been historically observed in Taiwan and Bangladesh but the contaminant has been affecting the health of people globally. Strong associations have been confirmed between exposure to high-levels of arsenic in drinking water and a wide range of diseases, including cancer. However, at lower levels of exposure, especially near the current World Health Organization regulatory limit (10μg/L), this association is inconsistent as the effects are mostly extrapolated from high exposure studies. This ecological study used Bayesian inference to model the relative risk of bladder and kidney cancer at these lower concentrations-0-2μg/L; 2-5μg/L and; ≥5μg/L of arsenic-in 864 bladder and 525 kidney cancers diagnosed in the study area, Nova Scotia, Canada between 1998 and 2010. The model included proxy measures of lifestyle (e.g. smoking) and accounted for spatial dependencies. Overall, bladder cancer risk was 16% (2-5μg/L) and 18% (≥5μg/L) greater than that of the referent group (water arsenic-levels within the current the World Health Organization maximum acceptable concentration.

  10. Risk management: a proposal for communication strategies

    Full Text Available Disasters related to natural hazards have increased in the last few decades. This increment makes it necessary to develop non-structural risk prevention and mitigation measures to improve people’s safety. An effective non-structural measure that can improve the preparedness of the population is a locally adapted communication campaign that is focused on natural hazards. We have developed a hypothetical communication campaign for a specific area in the north of Italy, in which hydro-geological risk is of considerable importance. The content of the campaign is defined by the combination of the requirements of the law with the results of a survey conducted in the study area. The aim of the survey is to evaluate the level of risk perception among the residents, and their attitudes towards prevention activities. The operative procedure of the campaign is modeled on advertising strategies. The campaign is designed to reach each family, and it is aimed at affecting people’s everyday life through a horizontal communication strategy that involves flyers, billboards, umbrellas and a website. The use of umbrellas as a medium for the campaign is the key. People mostly use umbrellas when it rains. Rain is linked with hydrogeological risk. As the content of the campaign is printed on the umbrellas, each time people use these umbrellas, they remember the campaign. The campaign is integrated into a broader communication program that includes meetings with stakeholders, activities in schools, and public conferences. The final goal is to foster the creation of a shared knowledge about risk in the whole population.

    The Mochovce National Radwaste Repository is a near surface multi-barrier disposal facility for disposal of processed low and very low level radioactive wastes (radwastes) resulting from the operation and decommissioning of nuclear facilities situated in the territory of the Slovak Republic and from research institutes, laboratories, hospitals and other institutions (institutional RAW) which are in compliance with the acceptance criteria. The basic safety requirement of the Repository is to avoid a radioactive release to the environment during its operation and institutional inspection. This commitment is covered by the protection barrier system. The method of solution designed and implemented at the Repository construction complies with the latest knowledge and practice of the repository developments all over the world and meets requirements for the safe radwaste disposal with minimum environmental consequences. All wastes are solidified and have to meet the acceptance criteria before disposal into the Repository. They are processed and treated at the Bohunice RAW Treatment Centre and Liquid RAW Final Treatment Facility at Mochovce. The disposal facility for low level radwastes consists of two double-rows of reinforced concrete vaults with total capacity 7 200 fibre reinforced concrete containers (FCCs) with RAW. One double-row contains 40 The operation of the Repository was started in year 2001 and after ten years, in 2011 was conducted the periodic assessment of nuclear safety with positive results. Till the end of year 2014 was disposed to the Repository 11 514 m 3 RAW. The analysis of total RAW production from operation and decommissioning of all nuclear installation in SR, which has been carried out in frame of the BIDSF project C9.1, has showed that the total volume estimation of conditioned waste is 108 thousand m 3 of which 45.5 % are low level waste (LLW) and 54,5 % very low level waste (VLLW). On the base of this fact there is the need to build 7

    Full text of publication follows: several European countries require a risk analysis for the production, storage or transport a dangerous goods. This requirement imposes considerable administrative effort for some sectors of the industry. In order to minimize the effort of such studies, a generic risk analysis for an industrial sector proved to help. Standardised procedures can consequently be derived for efficient performance of the risk investigations. This procedure was successfully established in Switzerland for natural gas transmission lines and fossil fuel storage plants. The development process of the generic risk analysis involved an intense discussion between industry and authorities about methodology of assessment and the criteria of acceptance. This process finally led to scientific consistent modelling tools for risk analysis and to an improved communication from the industry to the authorities and the public. As a recent example, the Holland-Italy natural gas transmission pipeline is demonstrated, where this method was successfully employed. Although this pipeline traverses densely populated areas in Switzerland, using this established communication method, the risk problems could be solved without delaying the planning process.

    Obesity is one of the most important link factors to coronary artery disease development mainly due to the pro-inflammatory and pro-thrombotic states favoring atherosclerosis progression. The LLLT acts in the cellular metabolism and it is highly effective to improve inflammation. The same occur in response to different kinds of exercise. However, we have not known the associate effects using LLLT therapies with aerobic plus resistance training as strategy specifically with target at human obesity control and its comorbidities. Investigate the effects of the LLLT associated with aerobic plus resistance training on cardiometabolic risk factors in obese women. Women aged 20-40 years (BMI ≥ 30 kg/m(2)), were divided into 2 groups: Phototherapy (PHOTO) and Placebo. They were trained aerobic plus resistance exercises (in a concurrent mode), 1h, 3 times/week during 16 weeks. Phototherapy was applied after each exercise session for 16 min, with infrared laser, wavelength 808 nm, continuous output, power 100 mW, and energy delivery 50 J. The body composition was measured with bioimpedance. Inflammatory mark concentrations were measured using a commercially available multiplex. LLLT associated with aerobic plus resistance training was effective in decrease neck (P=0.0003) and waist circumferences (P=0.02); percentual of fat (P=0.04); visceral fat area (P=0.02); HOMA-IR (P=0.0009); Leptin (P=0.03) and ICAM (P=0.03). Also, the reduction in leptin (P=0.008) and ICAM-1 (0, 05) was much more expressive in the phototherapy group in comparison to placebo group when analyzed by delta values. LLLT associated with concurrent exercise (aerobic plus resistance training) potentiates the exercise effects of decreasing the cardiometabolic risk factors in obese woman. These results suggest the LLLT associated with exercises as a new therapeutic tool in the control of obesity and its comorbidities for obese people, targeting to optimize the strategies to control the cardiometabolic risk

    Man's environment contains naturally occurring radionuclides and doses from exposures to these radionuclides mostly cannot be avoided. Consequently, almost everything may be considered as very low level radioactive material. In practical terms, management and the selection of different routes for low level material is confined to material which was subject to industrial processing or which is under a system of radiological control. Natural radionuclides with concentrations reaching reporting or notification levels will be discussed below; nevertheless, the main body of this paper will be devoted to material, mainly of artificial origin, which is in the system involving notification, registration and licensing of practices and sources. It includes material managed in the nuclear sector and sources containing artificially produced radionuclides used in hospitals, and in industry. Radioactive materials emit ionising radiations which are harmful to man and his environment. National and international regulations provide the frame for the system of radiation protection. Nevertheless, concentrations, quantities or types of radionuclide may be such, that the material presents a very low hazard, and may therefore be removed from regulatory control, as it would be a waste of time and effort to continue supervision. These materials are said to be exempted from regulatory control. Material exempted in a particular country is no longer distinguishable from ''ordinary'' material and may be moved from country to country. Unfortunately, criteria for exempting radioactive materials differ strongly between countries and free trade. Therefore there is a necessity for an international approach to be developed for exemption levels

    in Chile, the increase of childhood obesity has become a pandemic, and it has become a major public health problem. the purpose of this study was to determine the prevalence of malnutrition in children-adolescents and to analyze its association with cardiometabolic risk and physical performance. 342 students participated in this investigation (191 men and 151 women), who were between 11 and 16 years old, was evaluated index of corporal mass (IMC), body mass percentage (BMP), waist contour (WC), waist-to-height ratio (WHtR) and physical yield across multiple test. the 3.2 % of the children-adolescent had low weight, the 48.5 % normal weight, 30.9 % overweight and 17.3 % were obese. The categories were analyzed as the presence or not of overweight and obesity. It was reported an inverse relationship between nutritional status and physical performance. School children with obesity, in comparison with those without, showed a significant increase in anthropometric measures, as well as a decrease in the physical performance (p.

    2004-01-01

    The perception of risks for environment and health deriving from globalization processes and an uncontrolled use of modern technologies is growing everywhere. The greater the capacity of controlling living conditions, the larger is the possibility of misusing this power. In environmental and occupational health research we tend to reduce the complexity of the observed phenomena in order to facilitate conclusions. In social and political sciences complexity is an essential element of the context, which needs to be continuously considered. The Precautionary Principle is a tool for facing complexity and uncertainty in health risk management. This paper is aimed at demonstrating that this is not only a problem of technical risk assessment. Great attention should also be paid to improve risk communication. Communication between the stakeholders (experts, decision makers, political and social leaders, media, groups of interest and people involved) is possibly the best condition to be successful in health risk management. Nevertheless, this process usually runs up against severe obstacles. These are not only caused by existing conflicts of interest. Differences in values, languages, perceptions, resources to have access to information, and to express one's own point of view are other key aspects.

  1. The Nevada initiative: A risk communication Fiasco

    1993-01-01

    The U.S. Congress has designated Yucca Mountain, Nevada as the only potential site to be studied for the nation's first high-level nuclear waste repository. People in Nevada strongly oppose the program, managed by the U.S. Department of Energy. Survey research shows that the public believes there are great risks from a repository program, in contrast to a majority of scientists who feel the risks are acceptably small. Delays in the repository program resulting in part from public opposition in Nevada have concerned the nuclear power industry, which collects the fees for the federal repository program and believes it needs the repository as a final disposal facility for its high-level nuclear wastes. To assist the repository program, the American Nuclear Energy Council (ANEC), an industry group, sponsored a massive advertising campaign in Nevada. The campaign attempted to assure people that the risks of a repository were small and that the repository studies should proceed. The campaign failed because its managers misunderstood the issues underlying the controversy, attempted a covert manipulation of public opinion that was revealed, and most importantly, lacked the public trust that was necessary to communicate credibly about the risks of a nuclear waste facility. This article describes the advertising campaign and its effects. The manner in which the ANEC campaign itself became a controversial public issue is reviewed. The advertising campaign is discussed as it relates to risk assessment and communication. 29 refs., 2 tabs

    This paper reports on a study of ''Advanced Low-Level Radioactive Waste Treatment Systems'' conducted under an EPRI contract. The object of the study is to identify advanced lowlevel radwaste treatment systems that are commercially available or are expected to be in the near future. The current state-ofthe-art in radwaste solidification technology is presented. Related processing technologies, such as the compaction of dry active waste (DAW), containers available for radwaste disposal, and the regulatory aspects of radwaste transportation and solidification, are described. The chemical and physical properties of the currently acceptable solidification agents, as identified in the Barnwell radwaste burial site license, are examined. The solidification agents investigated are hydraulic cements, thermoplastic polymers, and thermosetting polymers. It is concluded that solidification processes are complex and depend not only on the chemical and physical properties of the binder material and the waste, but also on how these materials are mixed

  5. Low-level radioactive biomedical wastes

    International Nuclear Information System (INIS)

    Casarett, G.W.

    A summary of the management and hazards of low-level radioactive biomedical wastes is presented. The volume, disposal methods, current problems, regulatory agencies, and possible solutions to disposal problems are discussed. The benefits derived from using radioactivity in medicine are briefly described. Potential health risks are discussed. The radioactivity in most of the radioactive biomedical waste is a small fraction of that contained naturally in the human body or in the natural environment. Benefit-risk-cost considerations are presented. The cost of managing these wastes is getting so high that a new perspective for comparison of radioactivity (facts, risks, costs, benefits and trade-offs) and alternate approaches to minimize the risk and cost and maximize the benefits is suggested

    Johnson, B.B.

    1993-01-01

    The maturation of the field of risk communication has resulted in several manuals, a National Research Council review, a Society for Risk Analysis subgroup, and critics. Critics Pieter-Jan Stalen and Rob Coppock, and Harry Otway and Brian Wynne, have pointed out that much risk communication is impractical or paradoxical. In this letter, the author supports many of the criticisms of these critics, but also discusses errors and omissions in their viewpoints that he feels will inhibit progress in effective risk communication. Topics discussed are motivations for risk communication, the practicality of advice, the audience for risk communication, credibility, and whose interests are best served by risk communication. The purpose of this essay is therefore to spur further debate on the issue of risk communication. 13 refs

  9. Alerting the apathetic and reassuring the alarmed: communicating about radon risk in three communities. Final report

    International Nuclear Information System (INIS)

    Chess, C.; Hance, B.J.

    1988-01-01

    Public reaction to the risk from radon varied widely in three communities chosen for qualitative analysis. In Boyertown, PA, some residents were very alarmed, but most were apathetic toward this newly identified environmental risk. In Clinton, NJ, residents were concerned and worked with the mayor and the state to determine whether they were at risk and to disseminate information about mitigation of high indoor radon levels. Residents in Vernon, New Jersey were very alarmed and actively opposed the state's decision to site low-level radium wastes there. The qualitative study examines why reactions differed among the three communities, and extracts lessons for communicating about the risk from radon. These lessons should apply to communicating about other environmental hazards to individuals and communities

    1995-01-01

    Health in a multicellular organism is maintained by homeostatic processes. Disruption of these homeostatic controls at the molecular, biochemical, cellular, and organ systems levels can be brought about by irreversible changes in the genetic material (mutagenesis), cell death (cytotoxicity), or reversible changes in the expression of genes at the transcriptional, translational, or posttranslational levels (epigenesis). While radiation is known to induce DNA damage/mutations, cell, death and epigenetic changes, in addition to cancers that are found in radiation-exposed animals, experimentally, and in humans, epidemiologically, the question is, At low-level exposure, what is the risk that cancers are open-quotes causedclose quotes by the radiation?

    The LHC RF consists of eight 400 MHz superconducting cavities per ring, with each cavity independently powered by a 300 kW klystron, via a circulator. The challenge for the Low Level is to cope with very high beam current (more than 1 A RF component) and achieve excellent beam lifetime (emittance growth time in excess of 25 hours). Each cavity has an associated Cavity Controller rack consisting of two VME crates which implement high gain RF Feedback, a Tuner Loop with a new algorithm, a Klystron Ripple Loop and a Conditioning system. In addition each ring has a Beam Control system (four VME crates) which includes a Frequency Program, Phase Loop, Radial Loop and Synchronization Loop. A Longitudinal Damper (dipole and quadrupole mode) acting via the 400 MHz cavities is included to reduce emittance blow-up due to filamentation from phase and energy errors at injection. Finally an RF Synchronization system implements the bunch into bucket transfer from the SPS into each LHC ring. When fully installed in 2007, the...

    To conduct basic research on how people receive, evaluate, and form positions on scientific information and its relationship to low-dose radiation exposure. There are three major areas of study in our research program. First is the development of theories, frameworks and concepts essential to guiding data collection and analysis. The second area is a program of experimental studies on risk perception, evaluation of science information, and the structure of individual positions regarding low dose exposures. This involves the study of existing knowledge and the evaluation of science information presented within a variety of formats, as educational information, news media stories, and alternative communication methods (personal contact, small group interaction, email and internet, etc.). Third is the community-level studies to examine and record how the social conditions, under which science communications take place, influence the development of attitudes and opinions about: low- dose exposures, the available management options, control of radiation risks, and preferences for program and policy goals

    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.

    2008-12-01

    Full Text Available Despite vigorous research on risk communication, little is known about the social forces that drive these choices. Erev, Wallsten, and Neal (1991 showed that forecasters learn to select verbal or numerical probability estimates as a function of which mode yields on average the larger group payoffs. We extend the result by investigating the effect of group size on the speed with which forecasters converge on the better communication mode. On the basis of social facilitation theory we hypothesized that small groups induce less arousal and anxiety among their members than do large groups when performing new tasks, and therefore that forecasters in small groups will learn the better communication mode more quickly. This result obtained in Experiment 1, which compared groups of size 3 to groups of size 5 or 6. To test whether social loafing rather than social facilitation was mediating the effects, Experiment 2 compared social to personal feedback holding group size constant at 3 members. Learning was faster in the personal feedback condition, suggesting that social facilitation rather than loafing underlay the results.

    This paper assesses the impact of different modes of communicating information about risks that are cumulative, uncertain, and long-term (CULT). Do communications that emphasize potential ecological problems have a different impact from messages that discuss health concerns? Is a more emotional style more effective than a traditional standard approach? CULT risks, including those commonly associated with high-level radioactive waste, pose particular problems for risk communicators. nevertheless, the research shows that relatively simple risk communications can effectively lower risk estimates and reduce fears of negative consequences from CULT risks

    Worldwide, natural hazard risks, and especially flood risk, are increasing dramatically as populations grow, infrastructure deteriorates, and climate change worsens. Street level modeling technologies may help decision makers and the general public understand risk and explore options for building resilience. But there are challenges in linking powerful visualization technologies to people in ways that they trust, support and can use. Technology adoption depends on a host of social and psychological factors—for example, how have past experiences shaped perceptions? Where do people currently turn for information? Who do they trust? Who do they see as responsible for implementing response and resilience measures? What do people think about climate change and sea level rise? What are the values that will motivate them to act? The answers vary from place to place and group to group. Visualization technologies that are responsive to this type of information may be most effective. Through household level survey data collected at sites in California and Mexico, we identify factors that may help in designing effective flood risk communication tools.

    As droughts continue to impact businesses and communities throughout the United States, there needs to be a greater emphasis on drought communication through interdisciplinary approaches, risk communication, and digital platforms. The purpose of this research is to provide an overview of the current literature on communicating drought and suggests areas for further improvement. Specifically, this research focuses on communicating drought through social media platforms such as Facebook, Twitter, and Instagram. It also focuses on the conglomeration of theoretical frameworks within the realm of risk communication, to provide a strong foundation towards future drought communication. This research proposal provides a critical step to advocate for paradigmatic shifts within natural hazard communication.

    1995-12-31

    The Department of Energy through the National Low-Level Waste Management Program and WMG Inc. have entered into a joint development effort to design, build, and demonstrate the Packaged Low-Level Waste Verification System. Currently, states and low-level radioactive waste disposal site operators have no method to independently verify the radionuclide content of packaged low-level waste that arrives at disposal sites for disposition. At this time, the disposal site relies on the low-level waste generator shipping manifests and accompanying records to ensure that low-level waste received meets the site`s waste acceptance criteria. The subject invention provides the equipment, software, and methods to enable the independent verification of low-level waste shipping records to ensure that the site`s waste acceptance criteria are being met. The objective of the prototype system is to demonstrate a mobile system capable of independently verifying the content of packaged low-level waste.

    2005-01-01

    This article describes a model of communication known as crisis and emergency risk communication (CERC). The model is outlined as a merger of many traditional notions of health and risk communication with work in crisis and disaster communication. The specific kinds of communication activities that should be called for at various stages of disaster or crisis development are outlined. Although crises are by definition uncertain, equivocal, and often chaotic situations, the CERC model is presented as a tool health communicators can use to help manage these complex events.

  10. Sodium monofluoroacetate (1080) risk assessment and risk communication

    International Nuclear Information System (INIS)

    Eason, Charles

    2002-01-01

    Sodium monofluoroacetate (1080) is a vertebrate pesticide widely used for possum control in New Zealand. Fluoroacetate is also a toxic component of poisonous plants found in Australia, South Africa, South America, and India. Because of its importance and effectiveness in pest control and the highly toxic nature of this compound, its acute sub-lethal and target organ toxicity have been extensively studied. In relation to its use as a pesticide its environmental fate, persistence, non-target impacts and general toxicology have been and continue to be extensively studied. Toxic baits must be prepared and used with extreme care, otherwise humans, livestock, and non-target wildlife will be put at risk. The high risk of secondary poisoning of dogs is a cause for concern. 1080 acts by interfering with cellular energy production. Possums die from heart failure, usually within 6-18 h of eating baits. Long-term exposure to sub-lethal doses can have harmful effects and strict safety precautions are enforced to protect contractors and workers in the bait manufacturing industry. Considerable care is taken when using 1080 to ensure that the risks of using it are outweighed by the ecological benefits achieved from its use. When its use is controversial, risk communicators must take care not to trivialise the toxicity of the compound. The benefits of 1080 use in conservation, pest control, and disease control should be weighed up alongside the risks of using 1080 and other techniques for pest control

    Graphic displays can enhance quantitative risk communication. However, empiric data regarding the effect of graphic format on risk perception is lacking. We evaluate the effect of graphic format elements on perceptions of risk magnitude and perceived truth of data. Preferences for format also were assessed. Participants (254 female primary care patients) viewed a series of hypothetical risk communications regarding the lifetime risk of breast cancer. Identical numeric risk information was presented using different graphic formats. Risk was perceived to be of lower magnitude when communicated with a bar graph as compared with a pictorial display (p graphic format used to convey quantitative risk information effects key domains of risk perception. One must be cognizant of these effects when designing risk communication strategies.

  12. Climate change risk perception and communication: addressing a critical moment?

    Science.gov (United States)

    Pidgeon, Nick

    2012-06-01

    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.

    The author has made efforts to establish risk communication in the nuclear industry since the JCO criticality accident. Some people understood the importance and the usefulness of risk communication both for local residents and their own business. Others, however, thought it troublesome, costly, and useless for their organization and nuclear safety. I think, unfortunately, experiences after the Fukushima accident force them to hesitate at communicating risks with the public more and more. I will discuss why and how risk communication of nuclear technology is difficult. (author)

Finally, the suggestions for the development of the risk communication of the nuclear and radiation in China had been provided. (authors)

  15. A radiation protection training program with a focus on communicating risk

    Clement, C.H.; Zelmer, R.L.; Tourneur, F.

    2000-01-01

    Radiation protection training is generally provided to promote a radiologically safe work environment, and to help ensure that doses are kept as low as reasonably achievable. In many cases, this reason makes good sense. Radiological risk can often be a significant concern when working with radioactive materials or radiation-emitting devices. However, in conducting the work of the Low-Level Radioactive Waste Management Office, it is often the case that the perception of radiological risk is of greater concern that the radiological risk itself. In this case, radiation protection training can serve another equally important purpose. It can be used to convey, in a balanced manner, the actual radiological risks associated with the work, and to put those risks in perspective. For individuals who are not familiar with radiation safety, effective radiation protection training that focuses on risk communication can reduce the level of concern surrounding work to be performed. This, in turn, can have an overall positive impact on the efficiency of the work, on goodwill within the community where the work is taking place, and even on the overall safety of those conducting the work. The radiation protection training program developed and implemented by the Low-Level Radioactive Waste Management Office is described in the context of other, more traditional radiation protection training programs.

  16. Risky business: challenges and successes in military radiation risk communication.

    Science.gov (United States)

    Melanson, Mark A; Geckle, Lori S; Davidson, Bethney A

    2012-01-01

    Given the general public's overall lack of knowledge about radiation and their heightened fear of its harmful effects, effective communication of radiation risks is often difficult. This is especially true when it comes to communicating the radiation risks stemming from military operations. Part of this difficulty stems from a lingering distrust of the military that harkens back to the controversy surrounding Veteran exposures to Agent Orange during the Vietnam War along with the often classified nature of many military operations. Additionally, there are unique military exposure scenarios, such as the use of nuclear weapons and combat use of depleted uranium as antiarmor munitions that are not found in the civilian sector. Also, the large, diverse nature of the military makes consistent risk communication across the vast and widespread organization very difficult. This manuscript highlights and discusses both the common and the distinctive challenges of effectively communicating military radiation risks, to include communicating through the media. The paper also introduces the Army's Health Risk Communication Program and its role in assisting in effective risk communication efforts. The authors draw on their extensive collective experience to share 3 risk communication success stories that were accomplished through the innovative use of a matrixed, team approach that combines both health physics and risk communication expertise.

  17. Health risk communication--a view from within industry.

    Science.gov (United States)

    Spivey, G H

    1991-01-01

    Health risk communication is discussed in respect to four principles of biomedical ethics: (1) autonomy, the need to protect confidentiality and provide decision-making information; (2) beneficence, an obligation to inform and to develop trust; (3) non-maleficence, not covering up study findings, not over- or underinterpreting data; and (4) justice, helping place risk in proper perspective. The epidemiologist's role in risk communication includes responsible interpretation of data, balanced and non-judgemental risk communication and careful attention to the biologic and population significance of study findings. Potential problem areas for epidemiologists which are discussed include deciding when risk is significant, working for an agency which does not want a communication to take place and the occasional need to violate confidentiality for overriding societal goals. The paper concludes with an example risk communication which illustrates some of the principles covered in the paper.

This article explores the theory and practice of risk communication and sets out the basic principles for good risk communication when dealing with new technologies, uncertainty, and cautious and sceptical consumers. After failure to communicate with consumers and stakeholders about the risk to human health from bovine spongiform encephalopathy (BSE) in the 1990s, Government Agencies in the United Kingdom have made significant improvements in risk communication. The official inquiry that followed the BSE crisis concluded that a policy of openness was the correct approach, and this article emphasises the importance of consultation, consistency and transparency. There are, however, many different factors that affect public perception of risk (religious, political, social, cultural, etc.) and developing effective risk communication strategies must take all of these complex issues into consideration.

  1. Importance of risk communication during and after a nuclear accident.

    Science.gov (United States)

    Perko, Tanja

    2011-07-01

    Past nuclear accidents highlight communication as one of the most important challenges in emergency management. In the early phase, communication increases awareness and understanding of protective actions and improves the population response. In the medium and long term, risk communication can facilitate the remediation process and the return to normal life. Mass media play a central role in risk communication. The recent nuclear accident in Japan, as expected, induced massive media coverage. Media were employed to communicate with the public during the contamination phase, and they will play the same important role in the clean-up and recovery phases. However, media also have to fulfill the economic aspects of publishing or broadcasting, with the "bad news is good news" slogan that is a well-known phenomenon in journalism. This article addresses the main communication challenges and suggests possible risk communication approaches to adopt in the case of a nuclear accident. Copyright © 2011 SETAC.

    Evaluating emergency risk communications is fraught with challenges since communication can be approached from both a systemic and programmatic level. Therefore, one must consider stakeholders' perspectives, effectiveness issues, standards of evidence and utility, and channels of influence (e.g., mass media and law enforcement). Evaluation issues related to timing, evaluation questions, methods, measures, and accountability are raised in this dialogue with emergency risk communication specialists. Besides the usual evaluation competencies, evaluators in this area need to understand and work collaboratively with stakeholders and be attuned to the dynamic contextual nature of emergency risk communications. Sample resources and measures are provided here to aid in this emerging and exciting field of evaluation.

    First, what are, for EDF, the main issues dealing with the future management of low level wastes (LLW) will be recalled; and followed by a description of what are the implications of implementing these management principles: areas zoning, set up of pathways, traceability of the wastes and associated controls. The origin of the wastes will then be described using both qualitative and quantitative approaches; the description will specifically address the spreading of wastes production in time. LLW management at EDF will then be envisaged: storage in a specific discharge, pathways for treatment and elimination of wastes with acceptable radiological impact and costs. The example of LLW oils will be developed: particularly as far as hypothesis and results concerning the radiological impacts are concerned. The choice of incineration will then be justified, however expected difficulties to implement it industrially will be pointed out. Other on going studies and their main results will be mentioned: the present time is a turning point on that issue between thought and action; to be on going dismantling must take into account the emerging principles and give rise to good communication.

    Risk management related to floods and dam failures requires input from a variety of stakeholders from both the private and the public sector. This paper provided details of a risk management communication strategy based on a consequence approach that established work sequence modes to achieve a multidisciplinary consensus of opinion. The communication of risk was considered as a bilateral exchange of information between concerned parties, who were divided into 2 spheres: (1) a public sphere which included interest groups, government agencies, individuals and the media; and (2) a technical sphere comprised of industry members, scientific experts, and government agencies. Divided between the 2 spheres, government agencies play a distinct role in both the communication and understanding of risk. In Quebec, municipal agencies are required to identify risk and develop plans that ensure public safety. Risk management plans developed by industry members are a valuable source of information for municipal authorities, who can identify vulnerabilities in their own risk communication strategies. In addition, members of the public play an important role in eliciting further risk communications to improve areas of vulnerability. Interest groups can demand further analyses from impartial sources on sensitive issues. Conflicting results offer a plurality of opinions that must be considered to obtain a consensus in risk assessment, which is the ultimate aim of all risk analyses and communications strategies. It was concluded that risk communication strategies benefit from the engagement of a variety of often conflicting views. 8 refs., 3 figs.

    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.

    We propose a shift in emphasis when communicating to people when the objective is to motivate household disaster preparedness actions. This shift is to emphasize the communication of preparedness actions (what to do about risk) rather than risk itself. We have called this perspective "communicating actionable risk," and it is grounded in diffusion of innovations and communication theories. A representative sample of households in the nation was analyzed using a path analytic framework. Preparedness information variables (including content, density, and observation), preparedness mediating variables (knowledge, perceived effectiveness, and milling), and preparedness actions taken were modeled. Clear results emerged that provide a strong basis for communicating actionable risk, and for the conclusion both that information observed (seeing preparedness actions that other have taken) and information received (receiving recommendations about what preparedness actions to take) play key, although different, roles in motivating preparedness actions among the people in our nation. © 2011 Society for Risk Analysis.

  14. Defining moments in risk communication research: 1996-2005.

    2006-01-01

    Ten years ago, scholars suggested that risk communication was embarking on a new phase that would give increased attention to the social contexts that surround and encroach on public responses to risk information. A decade later, many researchers have answered the call, with several defining studies examining the social and psychological influences on risk communication. This article reviews risk communication research appearing in the published literature since 1996. Among studies, social trust, the social amplification of risk framework, and the affect heuristic figured prominently. Also common were studies examining the influence of risk in the mass media. Among these were content analyses of media coverage of risk, as well as investigations of possible effects resulting from coverage. The use of mental models was a dominant method for developing risk message content. Other studies examined the use of risk comparisons, narratives, and visuals in the production of risk messages. Research also examined how providing information about a risk's severity, social norms, and efficacy influenced communication behaviors and intentions to follow risk reduction measures. Methods for conducting public outreach in health risk communication rounded out the literature.

    1988-01-01

    This paper analyses the origins of risk communication; why the role of the media is difficult to study; the relationship between media coverage and public opinion; the relationship between media coverage and 'reality'; some dilemmas for journalists; the politics of risk communication. More research needs to be done on this issue. Because of the complexities advances will depend partly on cooperation among risk analysts, communications experts, political theorists and philosophers; in any case, progress is likely to be slow and the research costly. The paper demonstrates: It matters greatly that journalists and the rest of us understand the context and the consequences of press coverage of risk issues. (orig./HSCH)

    nuclear radiation from Fukushima" which focus on mis-information and fear mongering. Nuclear power and NTR are powerful resources that can open many doors for future prosperity and capability. With great power comes great responsibility. Radiation and its effects need to be better understood, quantified, and communicated. A human mission to mars has its own risks of deep space radiation and is considered a considerable risk at 400 milli-Sieverts per year in deep space and 245 milli-Sieverts per year on the surface of Mars as measured by the Mars Curiosity mission. Although these quantities of ionizing radiation are within the astronaut career limit, it exceeds the yearly average amounts of ionizing radiation. Astronaut crews have experienced these levels of radiation before, but for durations shorter than a year, and a mission to Mars could possibly be 3 years in length. There is also evidence that people can comfortably handle higher levels of ionizing radiation where the radiation occurs naturally like Ramsar, Iran when people can experience 270 milli-Sieverts per year. A risk posture that the development, test, and flight of an NTR will meet opposition from groups who oppose nuclear energy must be likely and the impact can be sever to the effort. Active risk mitigation must be taken for an NTR full-scale development project. The NTR design must take into account safety for transport and off nominal conditions. Nuclear fuel element must consider containment of fission products and Low Enriched Uranium (LEU) that may meet less opposition should be considered for safety and security reasons. Even though testing was conducted on Rover/NERVA safely and successfully in the 60's with exhaust sent heavenward in to open air, modern testing of NTR must consider full containment and no release of ionizing radiation to the public and must meet the current requirement of no more than 0.1 milli-Sieverts per year to the public. 0.1 milli-Sieverts is equivalent to eating one banana or

    The Midwest Geological Sequestration Consortium, Schlumberger Carbon Services, and Archer Daniels Midland has implemented a comprehensive communications plan at the Illinois Basin - Decatur Project (IBDP), a one million metric tonne Carbon Capture and Storage project in Decatur, IL, USA funded by the U.S. Department of Energy's National Energy Technology Laboratory. The IBDP Communication Plan includes consortium information, funding and disclaimer citations, description of target audiences, media communications guidelines, paper and presentations guidelines, site visit information, crisis communication, on-site photography regulations, and other components. The creation, development, and implementation processes for the IBDP Communication Plan (the Plan) are shared in this paper. New communications challenges, such as how to address add-on research requests, data sharing and management, scope increase, and contract agreements have arisen since the Plan was completed in January 2009, resulting in development of new policies and procedures by project management. Integrating communications planning, risk assessment, and project management ensured that consistent, factual information was developed and incorporated into project planning, and constitutes the basis of public communications. Successful integration has allowed the IBDP to benefit from early identification and mitigation of the potential project risks, which allows more time to effectively deal with unknown and unidentified risks that may arise. Project risks and risks associated with public perception can be managed through careful planning and integration of communication strategies into project management and risk mitigation. ?? 2011 Published by Elsevier Ltd.

  18. Risk communications and the Chemical Stockpile Emergency-Planning Program

    Energy Technology Data Exchange (ETDEWEB)

    Vogt, B.M.; Sorensen, J.H.

    1994-09-01

    The CSEPP (Chemical Stockpile Emergency Preparedness Program) was created to improve emergency planning and response capabilities at the eight sites around the country that store chemical weapons. These weapons are scheduled to be destroyed in the near future. In preparation of the Draft Programmatic Environmental Impact Statement (DPEIS) for the Chemical Stockpile Disposal Program (CSDP), it was proposed that the Army mitigate accidents through an enhanced community emergency preparedness program at the eight storage sites. In 1986, the Army initiated the development of an Emergency Response Concept Plan (ERCP) for the CSDP, one of 12 technical support studies conducted during preparation of the Final Programmatic Environmental Impact Statement (FPEIS). The purpose of this document is to provide a fairly comprehensive source book on risk, risk management, risk communication research and recommended risk communication practices. It does not merely summarize each publication in the risk communication literature, but attempts to synthesize them along the lines of a set of organizing principles. Furthermore, it is not intended to duplicate other guidance manuals (such as Covello et al.`s manual on risk comparison). The source book was developed for the CSEPP in support of the training module on risk communications. Although the examples provided are specific to CSEPP, its use goes beyond that of CSEPP as the findings apply to a broad spectrum of risk communication topics. While the emphasis is on communication in emergency preparedness and response specific to the CSEPP, the materials cover other non-emergency communication settings. 329 refs.

    Cardiovascular disease (CVD) prevention guidelines encourage assessment of absolute CVD risk - the probability of a CVD event within a fixed time period, based on the most predictive risk factors. However, few General Practitioners (GPs) use absolute CVD risk consistently, and communication difficulties have been identified as a barrier to changing practice. This study aimed to explore GPs' descriptions of their CVD risk communication strategies, including the role of absolute risk. Semi-structured interviews were conducted with a purposive sample of 25 GPs in New South Wales, Australia. Transcribed audio-recordings were thematically coded, using the Framework Analysis method to ensure rigour. GPs used absolute CVD risk within three different communication strategies: 'positive', 'scare tactic', and 'indirect'. A 'positive' strategy, which aimed to reassure and motivate, was used for patients with low risk, determination to change lifestyle, and some concern about CVD risk. Absolute risk was used to show how they could reduce risk. A 'scare tactic' strategy was used for patients with high risk, lack of motivation, and a dismissive attitude. Absolute risk was used to 'scare' them into taking action. An 'indirect' strategy, where CVD risk was not the main focus, was used for patients with low risk but some lifestyle risk factors, high anxiety, high resistance to change, or difficulty understanding probabilities. Non-quantitative absolute risk formats were found to be helpful in these situations. This study demonstrated how GPs use three different communication strategies to address the issue of CVD risk, depending on their perception of patient risk, motivation and anxiety. Absolute risk played a different role within each strategy. Providing GPs with alternative ways of explaining absolute risk, in order to achieve different communication aims, may improve their use of absolute CVD risk assessment in practice.

  4. A new perspective on radiation risk communication in Fukushima, Japan

    2013-01-01

    The March 11, 2011 cascading disasters of the historic earthquake, unprecedented tsunami, and subsequent radioactive substances release from the Fukushima Daiichi nuclear power plant have shocked the world. But the specter of radiation exposure has complicated the earthquake and tsunami disaster aid activities. Herein is a personal commentary on the current status of the risk communication activities within the disaster populations in Fukushima prefecture. A literature review of the current scientific literature was performed focusing on risk communication within the Fukushima region during the disaster recovery phase. I have limited my commentary to only the 5 most relevant of the publications which focus exclusively on the issue of risk communication and the problems which have generated the urgency to improve risk communication. There were several themes which were consistently identified across the articles and echo some of the personal observations of the many types of responses which victims are now demonstrating: fear, anger, distrust, denial, confusion, uncertainty, ambivalence, and hyperbole stood out regarding their varied responses to the current radiological situation and, regarding the government role in risk communication, corruption and lack of transparency. Two recommendations for helping to address these issues in risk communication are the inclusion of a community intermediary and great use of community engagement in the disaster recovery process. Improved risk communication, perhaps using established guidelines and including both community intermediaries and improved community engagement, may prove useful within the radiation affected populations of Japan.

    2017-02-01

    Full Text Available In this article, we summarise research that identifies best practice for communicating about hazards where the risk is low but public concern is high. We apply Peter Sandman’s ‘risk = hazard + outrage’ formulation to these risks, and review factors associated with the amplification of risk signals. We discuss the structures that determine the success of risk communication strategies, such as the capacity for early communication to ‘capture’ the dominant representation of risk issues, the importance of communicating uncertainty, and the usefulness of engaging with communities. We argue that, when facing trade-offs in probable outcomes from communication, it is always best to choose strategies that maintain or build trust, even at the cost of initial overreactions. We discuss these features of successful risk communication in relation to a range of specific examples, particularly opposition to community water fluoridation, Ebola, and routine childhood immunisation.

  8. Risk Communication and the Pharmaceutical Industry: what is the reality?

    Science.gov (United States)

    Edwards, Brian; Chakraborty, Sweta

    2012-11-01

    Risk communication is central to the risk management strategy of a pharmaceutical company. Pharmaceutical companies primarily communicate risk through labelling tools such as the Summary of Product Characteristics (SmPC), package insert, patient information leaflet (PIL) and the carton, which are currently regulated based on templates such as those of the EU. Recent research raises concern about how effective the SmPC is alone in communicating risk. There is some evidence that carton design can influence risk comprehension. Processes to check new trade names cannot be confused with existing names is a simple measure to mitigate one form of risk. Given the central role and the vast amount of resource that is consumed, it is surprising there has not been extensive original research to see whether product information such as the SmPC is a good tool for communicating risk. Recently, EU agencies have assessed the communication value of the PIL and revised the template and guidelines. However, no evaluation of user testing has been conducted at European level since the introduction of these new requirements. As regards 'Dear Healthcare Professional Communications', there is inconsistent evidence about their ability to change patient and physician behaviour. There is a dearth of evidence about what sort of communications materials are the most effective under which circumstances. The use of templates restricts the flexibility of companies to adapt their risk messages to their targets. Effective communication requires understanding how different audiences perceive the message and what the fundamental drivers are for altering patient and prescriber behaviour to be safer. This requires careful consideration of the relationship between risk communication, perception and management. However, the focus of a company's risk communication plan is normally on the International Conference on Harmonisation (ICH) regions and their regulations. Although the same regulatory tools are

    1992-01-01

    Safe disposal of waste is a vital aspect of any industrial operation whether it be production of plastics, steel or chemicals or handling of radioactive materials. Appropriate methods must be used in every case. Radioactive waste falls into three distinct categories - high, intermediate and low-level. It is the solid low-level waste making up over 90% of the total which this booklet discusses. British Nuclear Fuels plc (BNFL) operates a site for the disposal of solid low-level waste at Driggs, some six kilometres south of Sellafield in West Cumbria. The daily operations and control of the site, the responsibility of the BNFL Waste Management Unit is described. (author)

    Perspectives for Risk Assessment''. The central question was the extent to which the sometimes fast-growing knowledge about molecular and cellular effects offers the desired basis for extrapolation. Against this setting, a number of more specific questions which have been hotly debated for some time were also addressed. One of the primary questions concerned the traditional but increasingly questioned division between stochastic and non-stochastic working agents, and the corresponding division between exposure-effect relations without a threshold and with a threshold. Thoughts were also exchanged on what is often referred to as hormesis: the notion that low levels of exposure could actually improve health. For the purpose of illuminating the many aspects of these issues, experts from a number of areas were invited. In addition to this, three agents were selected to serve as points of crystallization for the general debate: ionizing radiation, ultraviolet (UV) radiation and dioxins. The present report calls attention to a selection of issues which emerged during the discussions on the above-mentioned central topic. Various more detailed questions and the wider context of the points considered are described at greater length in the enclosed conference report and in the background documents attached to the report. What follows is a series of considerations regarding the scientific basis for the derivation of recommended exposure levels, viewed in the light of current procedures and against the background of the work of the Health Council. In the preparation of the following comments and recommendations, various Dutch experts have been consulted

    Patients understand information about risk better if it is communicated in numerical or visual formats (e.g. graphs) compared to verbal qualifiers only. How frequently different communication formats are used in clinical primary care settings is unknown. We collected socioeconomic and patient understanding data using questionnaires and audio-recorded consultations about cardiovascular disease risk. The frequencies of the communication formats were calculated and multivariate regression analysis of associations between communication formats, patient and general practitioner characteristics, and patient subjective understanding was performed. In 73% of 70 consultations, verbal qualifiers were used exclusively to communicate cardiovascular risk, compared to numerical (11%) and visual (16%) formats. Female GPs and female patient's gender were significantly associated with a higher use of verbal formats compared to visual formats (p=0.001 and p=0.039, respectively). Patient subjective understanding was significantly higher in visual counseling compared to verbal counseling (p=0.001). Verbal qualifiers are the most often used communication format, though recommendations favor numerical and visual formats, with visual formats resulting in better understanding than others. Also, gender is associated with the choice of communication format. Barriers against numerical and visual communication formats among GPs and patients should be studied, including gender aspects. Adequate risk communication should be integrated into physicians' education.

    Full Text Available Abstract Background Patients understand information about risk better if it is communicated in numerical or visual formats (e.g. graphs compared to verbal qualifiers only. How frequently different communication formats are used in clinical primary care settings is unknown. Methods We collected socioeconomic and patient understanding data using questionnaires and audio-recorded consultations about cardiovascular disease risk. The frequencies of the communication formats were calculated and multivariate regression analysis of associations between communication formats, patient and general practitioner characteristics, and patient subjective understanding was performed. Results In 73% of 70 consultations, verbal qualifiers were used exclusively to communicate cardiovascular risk, compared to numerical (11% and visual (16% formats. Female GPs and female patient's gender were significantly associated with a higher use of verbal formats compared to visual formats (p = 0.001 and p = 0.039, respectively. Patient subjective understanding was significantly higher in visual counseling compared to verbal counseling (p = 0.001. Conclusions Verbal qualifiers are the most often used communication format, though recommendations favor numerical and visual formats, with visual formats resulting in better understanding than others. Also, gender is associated with the choice of communication format. Barriers against numerical and visual communication formats among GPs and patients should be studied, including gender aspects.

    Risk communication about the high-level radioactive waste (HLW) disposal is necessary for public acceptance of HLW disposal program. Online Risk Communication Assistant Tool (ORCAT) system is developed in order to support risk communication for high-level radioactive disposal on World Wide Web. We have carried out two test operations of ORCAT system. First test operation is carried out from Jun. 26 to Feb. 13, 2003. After the first operation, we improved the ORCAT system, and carried out the second test operation from Dec. 4 to 22, 2004. In the second test operation, 20 participants replayed the questionnaire about usability of ORCAT system. In consequence, we found that the ORCAT system remains what need to refine, but is evaluated useful to the risk communication about the HLW disposal. (author)

  20. Effects of risk communication on natural hazards on real estate owners' risk perception and risk behaviour

    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

    The initial draft of the Low-Level Waste Treatment Handbook has been prepared and submitted to the DOE Low-Level Waste Management Program for review and comment. A revised draft is scheduled to be delivered to DOE Headquarters in December 1982. The Handbook is designed to be useful to all individuals and groups concerned with low-level wastes. It is one of several volumes that will ultimately comprise a Low-Level Waste Technology Handbook. The objective of the Low-Level Waste Treatment Handbook is to present an overview of current practices related to the segregation, classification, volume reduction, solidification, handling, packaging, and transportation of LLW for disposal in a shallow land burial facility. The Handbook is intended to serve as a guide to individuals interested in the treatment and handling of low-level radioactive waste. The Handbook will not explicitly tell the user how to design and operate LLW treatment facilities, but rather will identify (1) kinds of information required to evaluate the options, (2) methods that may be used to evaluate these options, and (3) limitations associated with the selection of the treatment options. The focus of the Handbook is providing guidance on how to do waste treatment for disposal by shallow land burial

    Meijnders, A L; Midden, C J; Wilke, H A

    2001-10-01

    This article describes how the effectiveness of risk communication is determined by the interaction between emotional and informative elements. An experiment is described that examined the role of negative emotion in communication about CO2 risks. This experiment was based on the elaboration likelihood model and the related heuristic systematic model of attitude formation. The results indicated that inducing fear of CO2 risks leads to systematic processing of information about energy conservation as a risk-reducing strategy. In turn, this results in more favorable attitudes toward energy conservation if strong arguments are provided. Individual differences in concern seem to have similar effects.

  4. Risk communication and radiological/nuclear terrorism: a strategic view.

    2011-11-01

    It is now widely recognized that effective communication is a crucial element in radiological/nuclear terrorism preparedness. Whereas in the past, communication and information issues were sometimes viewed as secondary in comparison with technical concerns, today the need to improve risk communication, public information, and emergency messaging is seen as a high priority. The process of improving radiological/nuclear terrorism risk communication can be conceptualized as occurring in four overlapping phases. The first phase involves the recognition that communication and information issues will be pivotal in shaping how a radiological/nuclear terrorism incident unfolds and in determining its outcome. This recognition has helped shape the second phase, in which various research initiatives have been undertaken to provide an empirical basis for improved communication. In the third and most recent phase, government agencies, professional organizations and others have worked to translate research findings into better messages and informational materials. Like the first and second phases, the third phase is still unfolding. The fourth phase in risk communication for radiological/nuclear terrorism-a mature phase-is only now just beginning. Central to this phase is a developing understanding that for radiological/nuclear terrorism risk communication to be fully effective, it must go beyond crafting better messages and materials (as essential as that may be). This emerging fourth phase seeks to anchor radiological/nuclear communication in a broader approach: one that actively engages and partners with the public. In this article, each of the four stages is discussed, and future directions for improving radiological/nuclear terrorism risk communication are explored.

    2007-01-01

    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.

    Speeding is one of the most relevant risk behaviors for serious and fatal accidents, particularly among young drivers. This study presents a tailoring strategy for anti-speeding communication. By referring to their motivational dispositions toward speeding derived from motivational models of health behavior, young car drivers were segmented into different risk groups. In order to ensure that risk communication efforts would actually be capable to target these groups, the linkage between the risk profiles and communication preferences were explored. The study was conducted on the basis of survey data of 1168 German car drivers aged between 17 and 24 years. The data reveal four types of risk drivers significantly differing in their motivational profiles. Moreover, the findings show significant differences in communication habits and media use between these risk groups. By linking the risk profiles and communication preferences, implications for tailoring strategies of road safety communication campaigns are derived. Promising segmentation and targeting strategies are discussed also beyond the current case of anti-speeding campaigns. Copyright © 2015 Elsevier Ltd. All rights reserved.

    In order to reduce the risk of the greenhouse effect, conventional thermal power plants should be substituted by maximum energy conservation, use of renewable energies, and low-risk, high-tech nuclear power plants. Motor traffic exhausts could be eliminated by alternative fuels, and trace gas reducers, such as tropical rain forests, preserved by financial adjustments. CFC's are to be reduced in any case in order to lower the ozone risk. (DG) [de

    Although the importance of risk communication has been pointed out over the last decade in nuclear community, both public authorities and nuclear industry have not conducted the definite actions yet. It will be reflected in the public eye that nuclear community's attitude toward communication and consultation with the public about risk issues is half-hearted, comparing with chemical and food safety fields which recently launched their risk communication activities. In this study, we conduct risk communication experiments on some risk issues associated with nuclear technology and its utilization in Tokai village, for the purpose of establishment of risk communication in our society that might be one of the new relationships between science and technology and society. The outcomes of FY2002 study are the following threefold; 1) preparation of risk communication experiments on nuclear technology and its utilization, 2) assessment of social effects of risk communication activities, 3) preparation of practical guidebook for risk communication experiments.

    The aim of this study are to develop an information system and guideline for nuclear risk communication between expert and citizens as well as between both experts in terms of lessons learned from serious disaster such as Fukushima Dai-ich NPP accident. Technical standards for disseminating a result and process of seismic/tsunami PRA (Probabilistic Risk Assessment) of nuclear facility as well as nuclear risk information in an emergency, and risk communication in normal times are needed. Tins study examines the framework, contents, and technical basis for developing an information system for nuclear risk communication. In addition, this study identifies the communication issues of nuclear risk communication concerning the seismic/tsunami PRA through the testing information systems in areas around nuclear facilities and by providing effective implementation guidelines. JNES has developed the information system specified as Protection of Nuclear Power Plants against Tsunamis and Post Earthquake considerations in the External Zone (TiPEEZ) as part of IAEA International Seismic Safety Centre (ISSC) Extra Budgetary Programme (EBP). The EBP is currently preparing technical documents (TECDOC) regarding the implementation of the TiPEEZ. After the Fukushima accident, there has been increasing demand for disaster mitigation systems to share risk information between nuclear organizations and local municipalities. JNES and Niigata Institute of Technology conduct implementation of TiPEEZ for the practical use based on the corroborative works with Kashiwazaki city and citizens. (author)

  11. The spectre of uncertainty in communicating technological risk

    Broesius, Michael T. [Univ. of California, Livermore, CA (United States)

    1993-12-01

    The literature does not clearly describe the potential moral and ethical conflicts that can exist between technology sponsors and the technical communicators whose job it is to present potentially risky technology to the non-technical people most likely to be imperiled by such risk. Equally important, the literature does not address the issue of uncertainty -- not the uncertainty likely to be experienced by the community at risk, but the unreliable processes and methodologies used by technology sponsors to define, quantify, and develop strategies to mitigate technological risks. In this paper, the author goes beyond a description of risk communication, the nature of the generally predictable interaction between technology advocates and non-technically trained individuals, and current trends in the field. Although that kind of information is critical to the success of any risk communication activity, and he has included it when necessary to provide background and perspective, without knowing how and why risk assessment is done, it has limited practical applicability outside the sterile, value-free vacuum in which it is usually framed. Technical communicators, particularly those responsible for communicating potential technological risk, must also understand the social, political, economic, statistical, and ethical issues they will invariably encounter.

    2011-11-01

    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.

  14. Communicating Health Risks under Pressure: Homeland Security Applications

    International Nuclear Information System (INIS)

    Garrahan, K.G.; Collie, S.L.

    2006-01-01

    The U.S. Environmental Protection Agency's (EPA) Office of Research and Development (ORD) Threat and Consequence Assessment Division (TCAD) within the National Homeland Security Research Center (NHSRC) has developed a tool for rapid communication of health risks and likelihood of exposure in preparation for terrorist incidents. The Emergency Consequence Assessment Tool (ECAT) is a secure web-based tool designed to make risk assessment and consequence management faster and easier for high priority terrorist threat scenarios. ECAT has been designed to function as 'defensive play-book' for health advisors, first responders, and decision-makers by presenting a series of evaluation templates for priority scenarios that can be modified for site-specific applications. Perhaps most importantly, the risk communication aspect is considered prior to an actual release event, so that management or legal advisors can concur on general risk communication content in preparation for press releases that can be anticipated in case of an actual emergency. ECAT serves as a one-stop source of information for retrieving toxicological properties for agents of concern, estimating exposure to these agents, characterizing health risks, and determining what actions need to be undertaken to mitigate the risks. ECAT has the capability to be used at a command post where inputs can be checked and communicated while the response continues in real time. This front-end planning is intended to fill the gap most commonly identified during tabletop exercises: a need for concise, timely, and informative risk communication to all parties. Training and customization of existing chemical and biological release scenarios with modeling of exposure to air and water, along with custom risk communication 'messages' intended for public, press, shareholders, and other partners enable more effective communication during times of crisis. For DOE, the ECAT could serve as a prototype that would be amenable to

    2003-06-01

    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.

    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.

    2018-01-01

     The issue of drug lag in Japan has been rapidly reduced in recent years, and newly approved drugs now become available on Japanese and international markets at the same time. In this context, the risk management plan (RMP) system was introduced in 2012. RMPs describe important safety concerns recognized by Japan's Pharmaceuticals and Medical Devices Agency (PMDA) and marketing authorization holders (MAHs), as well as safety measures that MAHs request healthcare professionals (HCPs) to follow. The publication of RMPs is expected to support the sharing of drug risk management among HCPs during the postmarketing phase. In addition, to encourage risk communication between HCPs and patients, the PMDA website provides drug guides for patients and other information to promote proper understanding of drugs by patients and their families and enable them to identify serious adverse drug reactions at an early stage. However, the results of surveys conducted by the PMDA in FY2014 and FY2015 revealed low levels of awareness of RMPs and drug guides for patients in hospitals and other healthcare institutions. The surveys also showed that information regarding the proper use of drugs from MAHs and the PMDA was not incorporated into practice at healthcare institutions, resulting in the repeated release of identical safety alerts. To facilitate the increased utilization of risk communication tools, the PMDA has been providing and disseminating these tools through its website. This study addresses those efforts and the associated challenges.

    This report identifies, evaluates, and compares alternatives for meeting the U.S. Department of Energy’s mission need for management of remote-handled low-level waste generated by the Idaho National Laboratory and its tenants. Each alternative identified in the Mission Need Statement for the Remote-Handled Low-Level Waste Treatment Project is described and evaluated for capability to fulfill the mission need. Alternatives that could meet the mission need are further evaluated and compared using criteria of cost, risk, complexity, stakeholder values, and regulatory compliance. The alternative for disposal of remote-handled low-level waste that has the highest confidence of meeting the mission need and represents best value to the government is to build a new disposal facility at the Idaho National Laboratory Site.

    Currently, states and low-level radioactive waste (LLW) disposal site operators have no method of independently verifying the radionuclide content of packaged LLW that arrive at disposal sites for disposal. At this time, disposal sites rely on LLW generator shipping manifests and accompanying records to insure that LLW received meets the waste acceptance criteria. An independent verification system would provide a method of checking generator LLW characterization methods and help ensure that LLW disposed of at disposal facilities meets requirements. The Mobile Low-Level Waste Verification System (MLLWVS) provides the equipment, software, and methods to enable the independent verification of LLW shipping records to insure that disposal site waste acceptance criteria are being met. The MLLWVS system was developed under a cost share subcontract between WMG, Inc., and Lockheed Martin Idaho Technologies through the Department of Energy's National Low-Level Waste Management Program at the Idaho National Engineering Laboratory (INEL)

    Coleman, J.A.

    1982-01-01

    The goals, objectives and activities of the Department of Energy's Low-Level Radioactive Waste Management program are reviewed. The goal of the overall Program is to support development of an acceptable, nationwide, near surface waste disposal system by 1986. The commercial LLW program has two major functions: (1) application of the technology improvements for waste handling, treatment and disposal, and (2) assistance to states as they carry out their responsibilities under the Low-Level Radioactive Waste Policy Act of 1980. The priorities for the commercial side of the Low-Level Waste Management Program have been established to meet one goal: to support development of an effective commercial management system by 1986. The first priority is being given to supporting state efforts in forming the institutional structures needed to manage the system. The second priority is the state and industry role in transferring and demonstrating treatment and disposal technologies

    Bord, R.J.

    1988-01-01

    According to the author, the goals of the 1980 Low-Level Radioactive Waste Policy Act have not been met. That act stipulated that regional disposal sites were to be established by 1986. To date, no new sites have been established and none are anywhere near the construction phase. Congress, responding to existing impasse, has extended the deadline to the end of 1992 with the passage of the Low-Level Radioactive Waste Policy Act. The reasons for the impasse are no mystery: local intransigence regarding waste of any kind, public fears of radiation hazards, and politicians' anxieties about their constituents' fears. The focus of this paper is the viability of ongoing attempts to overcome public intransigence in the case of disposal siting for low-level radioactive waste (LLRW)

    Although low-level wastes have been generated and have required processing for more than two decades now, it is noteworthy that processing methods are continuing to change. The changes are not only attributable to improvements in technology, but are also the result of changing regulations and economics and uncertainties regarding the future availabilities of burial space for disposal. Indeed, because of the changes which have and are taking place in the processing of low-level waste, an overview of the current situation is in order. This presentation is a brief overview of the processing methods generally employed to treat the low-level wastes generated from both fuel cycle and non-fuel cycle sources. The presentation is far too brief to deal with the processing technologies in a comprehensive fashion, but does provide a snapshot of what the current or typical processing methods are and what changes are occurring and why

  5. The French centralized low level radwaste treatment centre named CENTRACO

    1996-01-01

    Socodei, a subsidiary company of EdF and Cogema is commissioned to design, finance, build and operate two low level radwaste treatment facilities: a contaminated scrap metal melting unit, and a solid and liquid waste incinerator. These units frame a low level radwaste treatment centre named Centraco, located near Marcoule in the south of France, and will receive in 1998 waste coming from dismantling, maintenance and operating works of French and foreign nuclear sites. The decision to create this centre is due to the low density and large variety of low level radwaste which take a volume out of proportion with their activity, specially in the surface storage centre. Up to now, all low level radwaste were sent and stored with no treatment optimization in surface storage centres. Socodei proposes in one single site, to optimize low level radwaste management and reduce the volume of ultimate waste to be stored: in a ratio of one to ten by casting ingots coming from melting contaminated scrap metals; in a ratio of one to twenty by encapsulating earth ashes and ashes resulting from incineration of solid and liquid waste. This is a centralized treatment centre and that's why Centraco is a new waste management system. Getting together all means in one place reduces costs, avoids mismanagement and risk increase, and allows consistency in safety, environmental impact, transport and personnel radioprotection.

  9. Cartograms Facilitate Communication of Climate Change Risks and Responsibilities

    Science.gov (United States)

    Döll, Petra

    2017-12-01

    Communication of climate change (CC) risks is challenging, in particular if global-scale spatially resolved quantitative information is to be conveyed. Typically, visualization of CC risks, which arise from the combination of hazard, exposure and vulnerability, is confined to showing only the hazards in the form of global thematic maps. This paper explores the potential of contiguous value-by-area cartograms, that is, distorted density-equalizing maps, for improving communication of CC risks and the countries' differentiated responsibilities for CC. Two global-scale cartogram sets visualize, as an example, groundwater-related CC risks in 0.5° grid cells, another one the correlation of (cumulative) fossil-fuel carbon dioxide emissions with the countries' population and gross domestic product. Viewers of the latter set visually recognize the lack of global equity and that the countries' wealth has been built on harmful emissions. I recommend that CC risks are communicated by bivariate gridded cartograms showing the hazard in color and population, or a combination of population and a vulnerability indicator, by distortion of grid cells. Gridded cartograms are also appropriate for visualizing the availability of natural resources to humans. For communicating complex information, sets of cartograms should be carefully designed instead of presenting single cartograms. Inclusion of a conventionally distorted map enhances the viewers' capability to take up the information represented by distortion. Empirical studies about the capability of global cartograms to convey complex information and to trigger moral emotions should be conducted, with a special focus on risk communication.

  10. Low-level waste workshops. Final report

    International Nuclear Information System (INIS)

    1983-01-01

    The Low-Level Radioactive Waste Policy Act of 1980 specifies that each state is responsible for the disposal of the low-level waste which is generated within its boundaries. The Act states that such wastes can be most safely and efficiently managed on a regional basis through compacts. It also defines low-level waste as waste which is not classified as high-level radioactive waste, transuranic waste, spent nuclear fuel, or by-product material as defined in the Atomic Energy Act of 1954. The Policy Act also stipulates that regional agreements or compacts shall not be applicable to the transportation, management, or disposal of low-level radioactive waste from atomic energy defense activities or federal research and development activities. It also specifies that agreements or compacts shall take affect on January 1, 1986, upon Congressional approval. In February 1983, the US Department of Energy awarded a grant to the Council of State Governments' Midwestern Office. The grant was to be used to fund workshops for legislation on low-level radioactive waste issues. The purpose of the workshops was to provide discussion specifically on the Midwest Interstate Compact on Low-Level Radioactive Waste. Legislators from the states which were eligible to join the compact were invited: Delaware, Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Missouri, North Dakota, Ohio, South Dakota and Wisconsin. Virginia, Kansas and Nebraska were also eligible but had joined other compacts. Consequently, they weren't invited to the workshops. The Governor's office of West Virginia expressed interest in the compact, and its legislators were invited to attend a workshop. Two workshops were held in March. This report is a summary of the proceedings which details the concerns of the compact and expresses the reasoning behind supporting or not supporting the compact

  11. Brief Communication: The dark side of risk and crisis communication: legal conflicts and responsibility allocation

    Inadequate, misinterpreted, or missing risk and crisis communication may be a reason for practitioners, and sometimes science advisors, to become the subjects of criminal investigations. This work discusses the legal consequences of inadequate risk communication in these situations. After presenting some cases, the discussion focuses on three critical issues: the development of effective communication protocols; the role, tasks, and responsibilities of science advisors; and the collateral effects of practitioners' defensive behaviours. For example, if the avoidance of personal liability becomes a primary objective for practitioners, it may clash with other objectives, such as the protection of vulnerable communities or the transparency of decision making. The conclusion presents some ideas for future research on the legal aspects of risk communication.

      Purpose: It is important that the general practitioners (GPs) are able to intervene to reduce risk of disease. One of the key points in doing so is effective risk communication that decreases uncertainty about choice of treatment and gives the patients a greater understanding of benefits......, and psychological well-being.    Methods: 40 GPs receive training in risk communication. Each GP selects 7 patients with elevated cholesterol. These patients are informed about the opportunity to receive preventive pharmacological treatment. Another 280 patients receive the same opportunity from 40 GPs without...... their psychological well-being.   Conclusion: This randomised intervention study will produce new knowledge about the effect of training GPs in risk communication....

  13. Risk communication between Experts and the Public: Perceptions and Intentions

    International Nuclear Information System (INIS)

    Sjoeberg, Lennart; Verhost, Philippe; Bouzon, Arlette

    2002-01-01

    This paper develops a conceptual and theoretical analysis of risk communication in cases where experts and the public have widely divergent views about the size of a risk: experts find it very small but some members of the public have an opposite view. Other members of the public agree with the experts. Applications are chosen from the risk management problems inhere in the handling of spent nuclear fuel. It is pointed out that the conflicting views have very different bases.The role of trust is analyzed and while it is a crucial issue, it is much broader than what has usually been assumed. Trust refers not only to social trust (i.e. trust in experts or authorities/corporation) but also to basic notions regarding knowledge and science. In a communication situation, the communicated position with regard to risk seems may not be perceived correctly by any of the parties, and positions tend to be entrenched

    The 1986 Challenger accident coupled with the Chernobyl nuclear reactor accident increased public concern about the safety of spacecraft using nuclear technology. While three nuclear powered spacecraft had been launched before 1986 with little public interest, future nuclear powered missions would see significantly more public concern and require NASA to increase its efforts to communicate mission risks to the public. In 1987 a separate risk communication area within the Launch Approval Planning Group of the Jet Propulsion Laboratory was created to address public concern about the health, environmental, and safety risks of NASA missions. The lessons learned from the risk communication strategies developed for the nuclear powered Galileo, Ulysses, and Cassini missions are reviewed in this paper and recommendations are given as to how these lessons can be applied to future NASA missions that may use nuclear power systems and other potentially controversial NASA missions.

  15. Risk communication, public participation and the Seveso II directive

    1999-01-01

    Risk communication and public participation are considered in the context of the forthcoming requirements of the 'Seveso II' Directive. The discussion draws substantially on the findings of a research project which has investigated public perceptions of the risks from major accident hazards in seven communities in the UK. Implications for the Directive's requirements on emergency information provision, public access to safety reports and consultation on emergency plans are considered. Our conclusions stress the need for risk communication to be seen as a long term and ongoing process, involving active listening to public reasoning about risk and a sensitivity to the context in which communication is taking place. In meeting both needs and rights to information and encouraging and enabling public participation, we conclude that the Directive should contribute in some degree to an improved environment for dialogue and the building of trust.

    From 1955 to 2001, Japan Atomic Energy Agency (JAEA) carried out research and development projects related to uranium exploration, mining, refining, conversion and enrichment at/around Ningyo-toge in Japan. Subsequently, JAEA has been carrying out remediation of the uranium mine legacy sites and decommissioning of the nuclear fuel cycle facilities. JAEA has many experiences of communication with local stakeholders from these projects. Among such experiences, management of the waste rock sites became local concern in 1988, 27 years after completion of the exploration. The issue was resolved in 2012 after several efforts. From this experience, it was suggested that the lack of information sharing with local stakeholders and that the inadequate support to stakeholder's requests caused the delay of problem solving. Therefore, sustainable relationship with local stakeholders for over decades is important for JAEA Ningyo-toge Environmental Engineering Center. As reference, similar domestic cases were investigated and strategies for risk communication were planned. As follows; (1) Clarify roles and responsibilities of communication staffs for sustainable communicating with local residents. (2) Identify gaps in risk communication knowledge among center and local residents and work toward filling those gaps. (3) Improve the effectiveness of Ningyo-toge center's website and PR-magazines as primary mechanism for communicating with wide stakeholders. (4) Investigate new communication methods for sustainable communicating, such as combination of environmental restoration studies by experts and environmental learning activities by residents.

    Accompanied by construction of new nuclear power plants in the coming decades in China, risk management has become increasingly politicized and contentious. Nuclear risk communication is a critical component in helping individuals prepare for, respond to, and recover from nuclear power emergencies. It was discussed that awareness of trust and public attitudes are important determinants in nuclear power risk communication and management. However, there is limited knowledge about how to best communicate with at-risk populations around nuclear power plant in China. To bridge this gap, this study presented the attitudinal data from a field survey in under-building Haiyang nuclear power plant, Shandong Province to measure public support for and opposition to the local construction of nuclear power plant. The paper discussed the structure of the communication process from a descriptive point of view, recognizing the importance of trust and understanding the information openness. The results showed that decision-making on nuclear power was dominated by a closed "iron nuclear triangle" of national governmental agencies, state-owned nuclear enterprises and scientific experts. Public participation and public access to information on nuclear constructions and assessments have been marginal and media was a key information source. As information on nuclear power and related risks is very restricted in China, Chinese citizens (51%) tend to choose the government as the most trustworthy source. More respondents took the negative attitudes toward nuclear power plant construction around home. It drew on studies about risk communication to develop some guidelines for successful risk communication. The conclusions have vast implications for how we approach risk management in the future. The findings should be of interest to state and local emergency managers, community-based organizations, public health researchers, and policy makers.

    Melanoma patients are advised to perform regular risk-reduction practices, including sun protection as well as skin self-examinations (SSEs) and physician-led examinations. Melanoma-specific communication regarding family risk and screening may promote such behaviors. To this end, associations between patients' melanoma-specific communication and risk reduction were examined. Melanoma patients (N = 169) drawn from a population-based cancer registry reported their current risk-reduction practices, perceived risk of future melanoma, and communication with physicians and relatives about melanoma risk and screening. Patients were, on average, 56 years old and 6.7 years' post diagnosis; 51% were male, 93% reported "fair/very fair" skin color, 75% completed at least some college, and 22% reported a family history of melanoma. Patients reported varying levels of regular (always/nearly always) sun protection: sunscreen use (79%), shade seeking (60%), hat use (54%), and long-sleeve shirt use (30%). Only 28% performed thorough SSE regularly, whereas 92% reported undergoing physician-led skin examinations within the past year. Participants who were female, younger, and had a higher perceived risk of future melanoma were more likely to report past communication. In adjusted analyses, communication remained uniquely associated with increased sunscreen use and SSE. Encouraging melanoma patients to have a more active role in discussions concerning melanoma risk and screening with relatives and physicians alike may be a useful strategy to promote 2 key risk-reduction practices post melanoma diagnosis and treatment. Future research is needed to identify additional strategies to improve comprehensive risk reduction in long-term melanoma patients. Copyright © 2016 John Wiley & Sons, Ltd.

  19. Priorities for autism spectrum disorder risk communication and ethics.

    2013-11-01

    Autism spectrum disorders are an issue of increasing public health significance. The incidence of autism spectrum disorders has been increasing in recent years, and they are associated with significant personal and financial impacts for affected persons and their families. In recent years, a large number of scientific studies have been undertaken, which investigate genetic and environmental risk factors for autism, with more studies underway. At present, much remains unknown regarding autism spectrum disorder risk factors, but the emerging picture of causation is in many cases complex, with multiple genes and gene-environment interactions being at play. The complexity and uncertainty surrounding autism spectrum disorder risk factors raise a number of questions regarding the ethical considerations that should be taken into account when undertaking autism spectrum disorder risk communication. At present, however, little has been written regarding autism spectrum disorder risk communication and ethics. This article summarizes the findings of a recent conference investigating ethical considerations and policy recommendations in autism spectrum disorder risk communication, which to the authors' knowledge is the first of its kind. Here, the authors discuss a number of issues, including uncertainty; comprehension; inadvertent harm; justice; and the appropriate roles of clinicians, scientists, and the media in autism spectrum disorder risk communication.

    Abstract. The article deals with the study of psycholinguistic and sociocognitive dynamics of stancetaking in the communicative situation of risk. The concept of risk presupposes decision making, while the process of decision making is seen here as a stancetaking on risk. A speaker’s stance includes subjective expressions of the speaker’s attitude towards the object of conversation, his mood, evaluations, perspective, knowledge, point of view and opinion. Stances are reflected at different le...

    Issues surrounding the wide spectrum of (perceived) risks and possible benefits associated with the rapid advance of modern nanotechnology are deliberated. These include the current realities of nanotechnological hazards, their impact vis-à-vis perceived nanotech-risks and perceived nanotech-benefits, and the consequent repercussions on the public and society. It is argued that both the risks and the benefits of nanoscientific advances must be properly communicated if the public is to support this emerging technology. PMID:19823594

  2. On the genetic effects of low-level tritium

    1976-01-01

    Genetic risk assessment for potential hazard from environmental tritium to man becomes important with increasing nuclear-power industry. The purpose of this short review is to discuss the possible genetic effects of tritium from a view of genetic risk estimation. The discussion is based mainly on our experimental results on the chromosome aberrations induced in human lymphocytes by tritium at the very low-level. The types of chromosome aberrations induced by radiation from tritium incorporated into the cells are mostly chromatid types. The most interesting finding is that the dose-response relationship observed in both tritiated-water and tritiated-thymidine is composed of two phases. The examination on the nature of two-phase dose-response relationship is very important not only for the mechanisms of chromosome aberrations, but also for the evaluation of genetic risk from low-level radiation.

    1986-01-01

    The generation of low-level radioactive waste is a natural consequence of the societal uses of radioactive materials. These uses include the application of radioactive materials to the diagnosis and treatment of human disease and to research into the causes of human disease and their prevention. Currently, low level radioactive wastes are disposed of in one of three shallow land-burial disposal sites located in Washington, Nevada, and South Carolina. With the passage in December 1980 of Public Law 96-573, The Low-Level Radioactive Waste Policy Act, the disposal of low-level wastes generated in each state was identified as a responsibility of the state. To fulfill this responsibility, states were encouraged to form interstate compacts for radioactive waste disposal. At the present time, only 37 states have entered into compact agreements, in spite of the clause in Public Law 96-573 that established January 1, 1986, as a target date for implementation of state responsibility for radioactive wastes. Recent action by Congress has resulted in postponement of the implementation date to January 1, 1993

    In 1987, a group infection of hepatitis in patients receiving a contaminated fibrinogen product was first reported to the Japanese regulatory agency. Eventually, this serious drug incident involved more than 10,000 cases of infection. In response, the Government of Japan established a responding inspection committee in 2008 to make recommendations for the restructuring of drug regulatory administration. The final report was issued in 2010. One agenda item of this restructuring was the improvement of drug-related safety risk communications. Our research group on drug safety risk communications, which is funded by the Government of Japan, surveyed pharmaceutical companies regarding their perspective on current risk communications. The survey was conducted using an anonymous questionnaire developed for this study which included the three operational domains of targets, contents, and measures of drug risk communication. Fifty-two of the 74 member companies of the Post-marketing Surveillance Subcommittee of the Japan Pharmaceutical Manufacturer's Association participated, and this response rate of more than 70% was considered sufficient to ensure the external validity of the survey results. Results showed that the most highly prioritized aspect of risk messaging was the strength of evidence, and that outcome evaluation of risk communication gained recognition. Further, while physicians and pharmacists were the most prioritized communication targets, pharmacovigilance departments devoted the most resources to regulators, at more than 30%. The Internet was recognized as a useful public source of risk information, whereas Drug Guides for Patients delivered on the web were considered under-recognized. Further discussion of these results with the aim of enhancing the restructuring of the Japanese drug regulatory administration system are warranted.

  19. Lost in Interpretation – Communicating Risk to the Public

    2016-01-01

    Communicating radiation incidents and emergencies to the public always has been challenging. No other type of emergency is related to such disproportional risk perception, so little public knowledge about the subject matter and so many contradicting expert analyses when it comes to public communications. The rise of social media and citizen journalism resulted in a dramatic acceleration of global communications and widespread misinformation. News does not break on television anymore but on Twitter, Facebook & Co. As a consequence, professional communicators not only have to take initiative considerably faster than in the past and deal with rumours. Their message has to be brief and on the point and is sometimes limited to just some 140 characters, the maximum length of a Tweet. More than ever it is essential to timely communicate in plain language and to clearly tell what needs to be done to be safe and to remain safe. Otherwise, the public will be lost in interpretation.

News does not break on television anymore but on Twitter, Facebook & Co. As a consequence, professional communicators not only have to take initiative considerably faster than in the past and deal with rumours. Their message has to be brief and on the point and is sometimes limited to just some 140 characters, the maximum length of a Tweet. More than ever it is essential to timely communicate in plain language and to clearly tell what needs to be done to be safe and to remain safe. Otherwise, the public will be lost in interpretation.

  1. Speak no evil: The promotional heritage of nuclear risk communication

    International Nuclear Information System (INIS)

    Gwin, L.

    1990-01-01

    Louis Gwin addresses the critically important problem of nuclear risk communication. His research suggests that while an orderly evacuation of the population actually at risk may be workable in theory, the more likely occurrence is widespread panic and gridlock. Gwin's research suggests that existing programs of nuclear risk communication actually make this problem worse. He found that those who had received no prior information on what to do in an emergency were significantly more likely to do the right thing (e.g., await further instructions) than those who had received instructions. With utilities themselves retaining the ultimate responsibility for developing communication programs, it is not surprising that they have been reluctant; to issue instructions on what to do in the event of a nuclear accident is to acknowledge that such accidents can and do occur. Gwin makes no attempt to protray the nuclear industry as purposefully dishonest or evil. The bottom line is that programs that combine the communication of emergency plans with a latent desire to reassure the public fail in their primary purpose. As Gwin observes the key issue is one of trust. People see such communications as little more than propaganda put out by industry for its own purposes and do not trust the utilities to tell them what to do in the event of an accident. It will be every man for himself, with potentially disastrous consequences. How do we restore trust in nuclear risk communications? Gwin offers a number of valuable suggestions such as placing communication responsibility in state or local agencies or in FEMA, and to ensure some form of public participation in the development and communication of emergency plans. This is an excellent study of an important and timely subject. It provides a much needed picture of just how badly our plans are likely to work in the next nuclear emergency. Gwin's warning should be heeded by policymakers now, while there is still time

    Clear risk communication is one of the keys to establishing a positive relationship with the public at an environmental restoration site. This effort has been evolving at the Weldon Spring site over the past few years, with considerable input from the local community. The recent signing of the major cleanup decision for this site, which identifies on-site disposal as the remedy reflects the strength of the communication program that has evolved for the project

  3. Marburg biosafety and biosecurity scale (MBBS): a framework for risk assessment and risk communication.

    2015-01-01

    Current risk assessment and risk communication of biosafety and biosecurity concerns lack a convenient metric and conceptual framework. The absence of such a systematic tool makes communication more difficult and can lead to ambiguous public perception of and response to laboratory biosafety incidents and biosecurity threats. A new 7-category scoring scale is proposed for incidents and situations in laboratories related to the handling of human and animal pathogens. The scale aims to help clarify risk categories, facilitate coordination and communication, and improve public understanding of risk related to biosafety and biosecurity.

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

    Science.gov (United States)

    Dodoo, Alexander; Hugman, Bruce

    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.

    This study was conducted to explore the effects of an event history calendar (EHC) approach on adolescent sexual risk communication and sexual activity. Adolescent school-linked health clinic patients (n = 30) who reported sexual activity self-administered the EHC that was used by nurse practitioners (NPs; n = 2) during a clinic visit. Immediately pre- and post-visit, and at 1 and 3 months, adolescents reported sexual risk behaviors and perceptions about EHC communication on questionnaires and by interview. NPs reported their perceptions of EHCs by questionnaire after the visit and poststudy interview. The EHC approach facilitated communication and adolescent awareness of their risk behaviors. Scores increased on Amount of Communication, t(29) = 8.174, p Communication, t(29) = 3.112, p = .004; Client Involvement in Decision Making, t(29) = 3.901, p = .001, and Client Satisfaction with Interpersonal Style, t(29) = 3.763, p = .001. Adolescents reported decreased sexual intercourse at 1 month, p = .031. School nurses could use the EHC approach to facilitate adolescent communication and tailoring of interventions.

  6. Cornerstones of the Austrian radon risk communication strategy

    2015-01-01

    On behalf of the Federal Ministry of Agriculture, Forestry, Environment and Water Management (BMLFUW), the National Radon Centre of Austria developed the National Radon Risk Communication Strategy. The superior goal is the reduction of the radon exposure of Austrian citizens as well as the reduction of radon-related lung cancer deaths. Austria, like many other countries, follows the approach to raise awareness and to inform the public to achieve this goal. The presented strategy deals with the question of how radon protection issues can be communicated to the public, existing fears can be reduced and affected people can be motivated to take action (perform a radon test, if necessary, mitigate or install preventive measures in new buildings). The cornerstones of the National Radon Risk Communication Strategy can be summarized as follows: - Definition of communication goals - Identification and categorization of target groups - Development of specific key messages for each of the target groups - Determination of communication channels and assessment of their efficiency - Integration of the radon issue in education and training - Cooperation with relevant organizations and platforms. The communication objectives, target groups and communication paths (and their evaluation) will be discussed during the presentation in detail.

  7. Risk communication on the construction of radioactive waste treatment 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.

    Wilson, K.N.; Desvousges, W.H.; Smith, K.V.; Payne, J.

    1993-01-01

    Bright lines in environmental risk communication refer to the specific levels at which an environmental risk becomes a serious health threat and action should be taken to mitigate its effects. This study examined the effect of ''bright lines'' in risk communication by emphasizing the radon exposure threshold level of 4 picocuries per liter. Specifically, the authors developed a computer-assisted interview containing bright-line versions of risk information. The bright-line version contained a range of possible radon levels, the corresponding number of estimated lung cancer cases, the relative health risk from radon compared to other health risks, and the EPA guidelines for mitigating levels above 4 picocuries in the home. The non-bright line version was identical to the bright-line version, except it did not include the EPA's mitigation recommendations. Effect measures included respondents' change in perceived risk after reading their materials, intended testing behavior, and advice to their neighbor for a specified radon level either above or below the 4 picocury threshold level. This paper discusses broader policy implications for designing effective risk communication programs

    The people who asked me to give a talk for the Spanish Nuclear Society's 28th Annual Meeting, at the invitation of WIN (Women in Nuclear), have challenged me, or at least that is what my colleagues believe, to tackle the difficult task of venturing into fields unfamiliar to anyone who is not involved in University teaching in communication and journalism. However, the challenge was very appealing to me, first of all because it was an invitation from WIN (Women in Nuclear), which I would like to congratulate, together with the Steering Committee, for having selected Salamanca as the meeting venue in this very important year for this city (it has been selected as European cultural city for 2002, along with the Belgian city of Bruges), If there is any place that has been immersed in scientific culture throughout the centuries it is Salamanca, where every one of its stones could tell us a history of the convergence and divergence between knowledge and society. This Universidad Pontificia of Salamanca also encloses centuries of wisdom within its walls. I have mentioned the first reason for accepting the challenge: the invitation from WIN Espana. The second reason why I accepted is that, some years ago, the world of nuclear energy, them unknown to me, started coming up in conversations with friends, one of whom works in this field. That history of discovery began in a levelly little Swiss town, in Grundenwald, not far from Eintein's Bern, whom I will mention later on

  10. Evaluating Risk Communication After the Fukushima Disaster Based on Nudge Theory.

    Science.gov (United States)

    Murakami, Michio; Tsubokura, Masaharu

    2017-03-01

    Using nudge theory and some examples of risk communication that followed the Fukushima disaster, this article discusses the influences and justifications of risk communication, in addition to how risk communication systems are designed. To assist people in making decisions based on their own value systems, we provide three suggestions, keeping in mind that people can be influenced (ie, "nudged") depending on how risk communication takes place: (1) accumulate knowledge on the process of evaluating how the method of risk communication and a system's default design could impact people; (2) clarify the purpose and outcomes of risk communication; and (3) see what risk communication might be ethically unjustifiable. Quantitative studies on risk communication and collective narratives will provide some ideas for how to design better risk communication systems and to help people make decisions. Furthermore, we have shown examples of unjustifiable risk communication.

  11. Overview of treatment and conditioning of low-level wastes

    Trevorrow, L.

    1986-01-01

    The consideration of alternative technologies in low-level waste management is assumed to be partly a response to current demands for lower risk in waste disposal. One of the determinants of risk in waste disposal is the set of characteristics of the materials placed into disposal cells, i.e., the products of treatment and conditioning operations. The treatment and conditioning operations that have been applied to waste streams are briefly examined. Three operations are the most important determinants of the stability that will contribute to reducing risk at the disposal cell: compaction, high-integrity containers, and solidification. The status of these three operations is reviewed

    Fujita, Y.; Taguchi, Y.; Imamura, M.; Inoue, T.; Tanaka, S.

    1977-01-01

    A small end-window type gas-flow counter which has a sharpened needle (anode) against the end-window plane (cathode) was developed for low-level counting of β particles to the amount of less than one count per hour in solid sources of relatively high specific activity. The advantage of the needle counter for low-level work is that being of a conical shape the active volume as against the window area is small. The background count rate of 0.0092+-0.0005 cpm was obtained for a 10 mm dia needle counter operating in GM mode and in anticoincidence with a well-type NaI(Tl) guard crystal with massive shields. The counter design and the counter characteristics are presented in detail. The needle counter is simple in design, low-cost and stable in long time operation. (author)

    In the development and utilization of nuclear energy, variety of radioactive wastes arise. A largest part is low level radioactive wastes. In Japan, they are concentrated and solidified, and stored in drums. However, no low level wastes have yet been finally disposed of; there are now about 260,000 drums of such wastes stored on the sites. In Japan, the land is narrow, and its structure is geologically unstable, so that the sea disposal is sought. On the other hand, the development of technology for the ground disposal has lagged behind the sea disposal until recently because of the law concerned. The following matters are described: for the sea disposal, preparatory technology studies, environment safety assessment, administrative measures, and international control; for the ground disposal, experiments, surveys, disposal site selection, and the concept of island repositories.

    The operation of low background HPGe detectors at a depth of 225 m, reduced the background by two orders of magnitude; a large amount of the remaining background is still attributable to the cosmic rays. The selection of radiopure materials, the characterization of reference matrices and the measurements of low radioactivities in environmental samples are performed. Coupling the low level spectrometry with additional techniques, e.g. neutron activation, will allow to measure extremely low radioactivities. (orig.)

    In 1979, for the first time, low-level waste (LLW) was brought to the attention of policy makers in most states. For several decades, technical personnel had regulated and managed LLW, but elected officials and their staff had been largely ignorant of the origins and destination of low-level radioactive materials. Events in the fall of 1979 set in motion a sequence of events that has compelled the continuing attention of policy makers in every state in the nation. In December 1979, the Executive Committee of the National Governors' Association appointed an eight-member task force, chaired by Governor Bruce Babbitt of Arizona, to review low-level waste management and to formulate state policy by July 1980. The principal findings were as follows: 1. LLW could be managed most efficiently, both technically and politically, at the state level. 2. Each state should take responsibility for its own waste. 3. The creation of a regional waste management system by means of interstate compacts offered the best promise of creating new disposal capacity. 4. Regions should be allowed to exclude waste generated outside their borders after a specified date

    This report covers the followng: (1) history of low level waste disposal; (2) current practice at the five major DOE burial sites and six commercial sites with dominant features of these sites and radionuclide content of major waste types summarized in tables; (3) site performance with performance record on burial sites tabulated; and (4) proposed solutions. Shallow burial of low level waste is a continuously evolving practice, and each site has developed its own solutions to the handling and disposal of unusual waste forms. There are no existing national standards for such disposal. However, improvements in the methodology for low level waste disposal are occurring on several fronts. Standardized criteria are being developed by both the Nuclear Regulatory Commission (NRC) and by DOE. Improved techniques for shallow burial are evolving at both commercial and DOE facilities, as well as through research sponsored by NRC, DOE, and the Environmental Protection Agency. Alternatives to shallow burial, such as deeper burial or the use of mined cavities is also being investigated by DOE

    2016-10-01

    Risk communication about the Fukushima Daiichi nuclear power plant accident in 2011 was often not transparent, timely, clear, nor factually correct. However, lessons related to risk communication have been identified and some of them are already addressed in national and international communication programmes and strategies. The Fukushima accident may be seen as a practice scenario for risk communication with important lessons to be learned. As a result of risk communication failures during the accident, the world is now better prepared for communication related to nuclear emergencies than it was 5 years ago The present study discusses the impact of communication, as applied during the Fukushima accident, and the main lessons learned. It then identifies pathways for transparent, timely, clear and factually correct communication to be developed, practiced and applied in nuclear emergency communication before, during, and after nuclear accidents.

RESULTS: Of the 240 patients included for analyses, 112 were allocated to POL information and 128 to ARR. Patients redeeming a statin prescription totalled six (5.4%) when...... informed using POL, and 32 (25.0%) when using ARR. The level of confidence in decision and satisfaction with risk communication did not differ between the risk formats. CONCLUSION: Patients redeemed statin prescriptions less often when their GP communicated treatment effectiveness using POL compared......BACKGROUND: It is important that patients are well-informed about risks and benefits of therapies to help them decide whether to accept medical therapy. Different numerical formats can be used in risk communication but It remains unclear how the different formats affect decisions made by real...

  6. Vaccine hesitancy and trust. Ethical aspects of risk communication.

    Science.gov (United States)

    Nihlén Fahlquist, Jessica

    2018-03-01

    This paper analyses vaccination policy from an ethical perspective, against the background of the growing hesitancy towards e.g. the measles vaccine. The paper is normative and analyses ethical aspects of risk communication in the context of vaccination. It is argued that ethical analysis of risk communication should be done at the level of the message, the procedure and the effects. The paper takes examples from the Swedish context, linking the current lack of trust in experts to the 2009 vaccination policy and communication promoting the H1N1 vaccine Pandemrix. During the Swedish H1N1 vaccination policy in 2009, the message was that the vaccine is safe. However, a group of adolescents developed narcolepsy as a side effect of the vaccine. Taking this into account, it becomes clear that the government should communicate risks and benefits responsibly and take responsibility for individuals affected negatively by populational health interventions. To communicate respectfully entails not treating vaccine sceptics as ill-informed or less educated, but instead taking the concerns of the vaccine hesitant, who potentially could change their minds, as a starting-point of a respectful discussion. There will inevitably be individuals who suffer from side effects of justifiable population-based health promotion activities. However, the public should be able to trust the message and count on the government to take responsibility for individuals affected by side effects. This is important for normative reasons, but is additionally likely to contribute to restored and maintained trust.

Understanding the impact that different types of risk communication have played in real and perceived public health risks can provide information about how messages, policies and programs can and should be communicated in order to be most effective. The purpose of this systematic review is to identify the effectiveness of communication strategies and factors that impact communication uptake related to environmental health risks. A systematic review of English articles using multiple databases with appropriate search terms. Data sources also included grey literature. Key organization websites and key journals were hand searched for relevant articles. Consultation with experts took place to locate any additional references.Articles had to meet relevance criteria for study design [randomized controlled trials, clinical controlled trials, cohort analytic, cohort, any pre-post, interrupted time series, mixed methods or any qualitative studies), participants (those in community-living, non-clinical populations), interventions (including, but not limited to, any community-based methods or tools such as Internet, telephone, media-based interventions or any combination thereof), and outcomes (reported measurable outcomes such as awareness, knowledge or attitudinal or behavioural change). Articles were assessed for quality and data was extracted using standardized tools by two independent reviewers. Articles were given an overall assessment of strong, moderate or weak quality. There were no strong or moderate studies. Meta-analysis was not appropriate to the data. Data for 24 articles were analyzed and reported in a narrative format. The findings suggest that a multi-media approach is more effective than any single media approach.

  9. Risk communication for existing exposure situation after the nuclear disaster

    Yamaguchi, Ichiro

    2011-01-01

    The title subject is explained for its better understanding and recognition. The present state (Oct. 2011) where crisis of Fukushima Nuclear Accident has reached a settlement with release of 0.1 GBq/hr from the reactor container, is called the existing exposure situation. Radiation risk must be reduced under such a situation as people have to live in. Risk is defined to be a probability of matters undesirable, its size is assessed by various conditions and assumptions, it is manageable on its assessment, but its realization largely depends on subjectivity. Measures for lessening the risk usually accompany a load and disadvantage, leading to an antinomy structure (trade-off), of which problem is ultimately an ethical task of public health and cannot be solved in the form everybody agrees with. Therefore, a mutual consent among concerned people is required for deciding the principle of the risk management, for which the risk communication is essential. Risk communication about radiation is an unavoidable task of medical staffs as guided by International Commission of Radiological Protection (ICRP) (2001), International Atomic Energy Agency (IAEA) (2008) reports, World Health Organization (WHO), etc. However, the communication about radiation has now become also a task of the ordinary public under the present situation. For this, medical staffs are expected to play their role by acquiring the statistical literacy as well as with the radiological concept because the risk assessment accompanies the uncertainty. The author concludes that the risk communication is a problem of resolution to act, not of coping with. (T.T.)

    Full Text Available In the last few years, a continuous series of food alerts have caught the attention of the media and the public in Europe. First, eggs and pork contaminated with dioxins; then, “mad cow” disease, while, all along in the background, a battle against genetically modified plants has been in progress. These food alerts have had complex repercussions on the perception of risks associated with food production. Experts have often been divided over these issues, and the uncertainty of scientific data has been indicated on more than one occasion as one of the factors that influence risk perception. However, the most important factor seems to be undoubtedly the way in which the risk has been communicated (or not communicated to the public. Therefore, risk communication analysis offers an excellent opportunity to understand the profound changes that are taking place in relations among the scientific community, mass media and other members of civil society now that they are fully aware that scientific and technological innovation, the real driving force of modern industrial society, is a source of development but also a source of risks which are not always acceptable. Within this different context, a debate open to all interested parties appears to have become a dire necessity for the “risk society”, especially as far as food is concerned because food has extremely important psychological, ethical and cultural values.

  12. Challenges to communicate risks of human-caused earthquakes

    Klose, C. D.

    2014-12-01

    The awareness of natural hazards has been up-trending in recent years. In particular, this is true for earthquakes, which increase in frequency and magnitude in regions that normally do not experience seismic activity. In fact, one of the major concerns for many communities and businesses is that humans today seem to cause earthquakes due to large-scale shale gas production, dewatering and flooding of mines and deep geothermal power production. Accordingly, without opposing any of these technologies it should be a priority of earth scientists who are researching natural hazards to communicate earthquake risks. This presentation discusses the challenges that earth scientists are facing to properly communicate earthquake risks, in light of the fact that human-caused earthquakes are an environmental change affecting only some communities and businesses. Communication channels may range from research papers, books and class room lectures to outreach events and programs, popular media events or even social media networks.

    1985-01-01

    The Mock Site Licensing Demonstration Project has developed the Low-Level Radioactive Waste Siting Simulation, a role-playing exercise designed to facilitate the process of siting and licensing disposal facilities for low-level waste (LLW). This paper describes the development, content, and usefulness of the siting simulation. The simulation can be conducted at a workshop or conference, involves 14 or more participants, and requires about eight hours to complete. The simulation consists of two sessions; in the first, participants negotiate the selection of siting criteria, and in the second, a preferred disposal site is chosen from three candidate sites. The project has sponsored two workshops (in Boston, Massachusetts and Richmond, Virginia) in which the simulation has been conducted for persons concerned with LLW management issues. It is concluded that the simulation can be valuable as a tool for disseminating information about LLW management; a vehicle that can foster communication; and a step toward consensus building and conflict resolution. The DOE National Low-Level Waste Management Program is now making the siting simulation available for use by states, regional compacts, and other organizations involved in development of LLW disposal facilities

    Social media provide a unique channel for disseminating evidence-based information to diverse audiences and organizational and private stakeholders, thus facilitating a dialog about health and health risks. Guided by the social amplification of risk framework, the goal of this study was to assess the level of audience engagement with messages posted on the National Cancer Institute (NCI) Facebook page and evaluate the differences in the audience information behavior toward risk-related and non-risk posts. Data included 1,975 posts published on the NCI Facebook page as well as the corresponding 4,537 comments, 77,298 shares, and 145,462 likes. Links and images were the top two most frequent types of content for both risk-related and non-risk posts, but risk-related messages were more amplified through comments, shares, and likes. Comparing the modality of risk-related messages, videos, contrary to the prediction, were not more effective in attracting audience engagement than images. Finally, comments to risk-related posts did not repeat risk-related language suggesting that future studies should examine risk signal recognition and dissemination as separate behaviors. This study's findings emphasize the importance of focused investigation of message design strategies and message effects on the dissemination and amplification of communication related to health risks.

    2000-06-01

    Psychophysical studies of the short-term memory for attributes or dimensions of the visual stimulus that are known to be important in early visual processing (spatial frequency, orientation, contrast, motion and color) identify a low-level perceptual memory mechanism. This proposed mechanism is located early in the visual processing stream, prior to the structural description system responsible for shape priming but beyond primary visual cortex (V1); it is composed of a series of parallel, special-purpose perceptual mechanisms with independent but limited processing resources. Each mechanism is devoted to the analysis of a single dimension and is coupled to a memory store.

    The experiments conducted on cultured HeLa (tissue culture) cells revealed that there is a limit of dose above which adaptive response was not observed and a limit of dose below which this response was not induced. The exposure of cells in the territories with elevated radiation background leads to genome instability which results in enhanced radiosensitivity. Investigations on the blood lymphocytes of people living in contaminated regions revealed that adaptive response was more significant in children whereas in adults there was slight increase. Acute irradiation serves as a tool revealing the changes that took place in DNA during chronic low level irradiations after Chernobyl disaster. (author).

    The low-level radioactive waste produced in Instituto de Engenharia Nuclear is generated basically from three distinct modes: a particle accelerator (CV-28 Cyclotron), radiochemistry laboratories and the operation of a nuclear research reactor (Argonaut type). In the Cyclotron unit, all water flow from hot labs as well as from the decontamination laundry is retained in special tank with homogenizing system and a remote control, that signalizes when the tank gets a pre-specified level. Samples homogenized from the tank are colected for previous analysis. (Author) [pt

    An expert system has been developed as part of a new initiative for the Oak Ridge National Laboratory (ORNL) systems analysis program. This expert system will aid in prioritizing radioactive waste streams for treatment and disposal by evaluating the severity and treatability of the problem, as well as the final waste form. The objectives of the expert system development included: (1) collecting information on process treatment technologies for liquid low-level waste (LLLW) that can be incorporated in the knowledge base of the expert system, and (2) producing a prototype that suggests processes and disposal technologies for the ORNL LLLW system. 4 refs., 9 figs

  8. Low levels of extraneous agents in vaccine starting materials.

    Rouby, Jean-Claude

    2010-05-01

    There are different ways to define the concept of 'low levels' of extraneous agents in vaccines and vaccine starting materials, based on the amount of extraneous agents as such, the sensitivity of the detection method and the probability approach linked to the sampling method. None of these approaches, however, is entirely satisfactory--a general definition of a 'low level' cannot be provided. Since the main point is the safety of medicinal products, the risk analysis approach to 'low level' contaminations can be considered as a way to overcome the above mentioned deadlock. But as too many variables impact the risk analysis, it cannot be properly performed either. In practice, seeds are tested to show freedom from extraneous agents, the other raw materials are inactivated through a validated method. However, there are technical and regulatory limits in both cases, and neither testing nor inactivation entirely guarantees freedom from extraneous agents. Despite this unsatisfactory situation, it should be acknowledged that no truly significant disease outbreak linked to an extraneous agent has been identified until today. Regulatory actions are mainly undertaken when a sanitary problem occurs. In the end, companies remain responsible for their products. 2010 The International Association for Biologicals.

    As many as 8 million homes in the United States may have elevated radon levels, with accompanying lung cancer risks several orders of magnitude higher than for most other environmental risks. The U.S. Environmental Protection Program (EPA) does not have clear regulatory authority over radon, so has relied on an information program. Less than 5% of homes have been tested, which is disappointing from a public health stance. The report summarizes the available research on communicating about the risk from radon from the perspective of a psychologist. The research results are critiqued to draw practical conclusions for radon policy and suggest the most important topics for further risk communication research.

    Westinghouse Hanford Company (WHC) contracted a team consisting of Los Alamos Technical Associates (LATA), British Nuclear Fuel Laboratories (BNFL), Southwest Research Institute (SwRI), and TRW through the Tank Waste Remediation System (TWRS) Technical Support Contract to conduct a study on several areas concerning vitrification and disposal of low-level-waste (LLW). The purpose of the study was to investigate how several parameters could be specified to achieve full compliance with regulations. The most restrictive regulation governing this disposal activity is the National Primary Drinking Water Act which sets the limits of exposure to 4 mrem per year for a person drinking two liters of ground water daily. To fully comply, this constraint would be met independently of the passage of time. In addition, another key factor in the investigation was the capability to retrieve the disposed waste during the first 50 years as specified in Department of Energy (DOE) Order 5820.2A. The objective of the project was to develop a strategy for effective long-term disposal of the low-level waste at the Hanford site.

    In 1982, Prof. Thomas Don Luckey of Missouri Univ. asserted `Radiation Hormesis` on the Journal of Health Physics and he published two books. CRIEPI initiated the research program on Radiation Hormesis following his assertion to confirm `is it true or not?` After nearly ten year research activities on data surveys and animal tests with many Universities, we are realizing scientific truth of bio-positive effects by low level radiation exposures. The interesting bio-positive effects we found could be categorized in following five groups. 1) Rejuvenation of cells such as increase of SOD and cell membrane permeability, 2) Moderation of psychological stress through response of key enzymes, 3) Suppression and therapy of adult-diseases such as diabetes and hypertension, 4) Suppression of cancer through enhancement of immune systems such as lymphocytes, 5) Suppression of cancer and ratio-adaptive response by activation of DNA repair and apoptosis. In the responses of many specialists to our initiation of radiation hormesis research program following T.D. Luckey`s claim about low level radiation, I have to pick up for the first, the great success of Prof. Sakamoto. Prof. Sakamoto had been already applying whole body low dose irradiation for ten years before our radiation hormesis research started on the therapy to suppress the cancer reappearing after treatment. He reported about his successful trial to real patients and showed an enhancement of immune system. (author)

    1993-03-01

    The strategy for disposal of low-level radioactive waste in Russia differs from that employed in the US. In Russia, there are separate authorities and facilities for wastes generated by nuclear power plants, defense wastes, and hospital/small generator/research wastes. The reactor wastes and the defense wastes are generally processed onsite and disposed of either onsite, or nearby. Treating these waste streams utilizes such volume reduction techniques as compaction and incineration. The Russians also employ methods such as bitumenization, cementation, and vitrification for waste treatment before burial. Shallow land trench burial is the most commonly used technique. Hospital and research waste is centrally regulated by the Moscow Council of Deputies. Plans are made in cooperation with the Ministry of Atomic Energy. Currently the former Soviet Union has a network of low-level disposal sites located near large cities. Fifteen disposal sites are located in the Federal Republic of Russia, six are in the Ukraine, and one is located in each of the remaining 13 republics. Like the US, each republic is in charge of management of the facilities within their borders. The sites are all similarly designed, being modeled after the RADON site near Moscow.

    Full Text Available According to the latest approaches in the field, the integrated marketing communication requires a planned organizational approach, creating and maintaining in time good relations with the customers of its products or services, but also with its other stakeholders. According to the data provided by the National Statistics Institute (INS, the year 2014 is the first year in history when the Romanian exports exceeded the amount of EUR 50 billion. However, within the context of the economic crisis, numerous Romanian brands have disappeared from the market and Romania risks becoming a simple outlet market if the local companies do not improve their communication processes and skills, as sources of competitive advantage by which the Romanian products and services may differ in relation to those of the E.U. member countries. Within the context of business globalization and of the knowledge society, the present paper is trying to identify ways of developing the communication skills, which can be integrated in a formal risk management system, allowing the decrease of the risks triggered by the cultural differences specific of communication in international business.

  16. Risk communication. The key of the policy success

    Covalschi, Valentina

    2005-01-01

    Today, in a democratic society, nuclear power development is subject to public acceptance. The acceptance of the nuclear activities development implies both the approval by the government's proper authorities and also the standpoints of the civil society, expressed in forms more or less institutionalized. The public has an important role to play in addressing issues of health, safety and environment. Therefore, all activities of a nuclear organization need to be both transparent and should provide for the public's appropriate involvement, with input not only from the nuclear community, but also from members of the public, interested groups, media, as well as public representatives in local and national councils and groups. How to communicate clearly with the public is a very challenging job that requires special attention. Risk communication is the art or practice of talking about scientific information and principles to a non - expert audience. Its goal is to convey accurate and trustworthy information about safety to decision - makers, the public, or anyone else with an interest in the safety of the public or themselves. The science of communication, public education for a proper perception of risks are the key for attaining social acceptance of any technology that is about to become part of the sustainable development process and hence, of nuclear energy. The paper describes the way our nuclear organization is acting and the results in risk communication activity it achieves. (author)

    2014-01-01

    The radiobiological risks associated with medical imaging are generally considered to be small, if existent. However, the public view of the risk of medical radiation at diagnostic levels can be substantially different from the clinical reality. Radiation science is not taught to the general public, and so perception of radiation risks can be based on a variety sources, including some that may be misleading, incorrect, or sensationalized. Consequently, patients can have significant concerns about procedures they or their loved ones might have had or that might be needed in their medical care. It is the responsibility of the physicist to be able to communicate risk in a manner that is clear, understandable, and respectful. This session will present a number of real life scenarios of patient or family concern about radiation risks. The panel will, through demonstration or discussion, present various options for handling each situation. The audience will be involved in discussion and critique of the approaches presented. Learning Objectives: To gain insight to the patients perspective on radiation risk and how to respond professionally to their concerns. To learn basic principles for effectively communicating with patients about radiation risk. To gain tools and approaches for addressing a wide range of patient concerns

    This bulletin gives a basic understanding about issues and safety standards that are built into the transportation system for radioactive material and waste in the US. An excellent safety record has been established for the transport of commercial low-level radioactive waste, or for that matter, all radioactive materials. This excellent safety record is primarily because of people adhering to strict regulations governing the transportation of radioactive materials. This bulletin discusses the regulatory framework as well as the regulations that set the standards for packaging, hazard communications (communicating the potential hazard to workers and the public), training, inspections, routing, and emergency response. The excellent safety record is discussed in the last section of the bulletin

  1. Nuclear risk and communication: the essential role of safety authorities

    Hautin, N.

    1998-01-01

    Full text of publication follows: whether concerning mad cow disease, asbestos, nuclear, OGM or now, dioxin in French meat, public health risks have been making the headlines of newspapers for a while. And, firms whose activity is associated with these risks are in effect in the defendants box. Therefore, communicating becomes difficult: their word is suspect and, debates quite rapidly exceed the firm competencies to become a socio-cultural conflict. This paper explores in nuclear fields the essential role of safety authorities in such communication cases. Our surveys and the comparative case study between the pipe at La Hague and 'contaminated' nuclear transports in France are eloquent: the messages of nuclear firms is perceived through their image of a State within the State built from the past and reinforced by the negative prism of the news. Regular and technical arguments (the respect of norms) entertain the debate rather than hush it. That is why we could infer an objective, and independent opinion is required, one different from the firm, the public and ministries: its role of referee could allow a constructive dialog between the public and the firm. Risk communication nature and efficiency depend on that (cf. the diagram). As a solution, we think about a legitimate authority organization identified by the public first, but by other actors as well. From the public point of view, if we see the place of pressure groups (e.g. Greenpeace) in the debate as a measure of the lack of trust in the independence of safety authorities, we can infer that it is a reaffirmation of democracy which is demanded by the French public, which could be satisfied with powerful safety authorities. That is why safety authorities have an essential role to play, beyond this of control, in nuclear risk communication towards the public.

  2. Decision making biases in the communication of earthquake risk

    L'Aquila, with 6 scientists convicted of manslaughter, shocked the scientific community, leading to urgent re-appraisal of communication methods for low-probability, high-impact events. Before the trial, a commission investigating the earthquake recommended risk assessment be formalised via operational earthquake forecasts and that social scientists be enlisted to assist in developing communication strategies. Psychological research has identified numerous decision biases relevant to this, including hindsight bias, where people (after the fact) overestimate an event's predictability. This affects experts as well as naïve participants as it relates to their ability to construct a plausible causal story rather than the likelihood of the event. Another problem is availability, which causes overestimation of the likelihood of observed rare events due to their greater noteworthiness. This, however, is complicated by the 'description-experience' gap, whereby people underestimate probabilities for events they have not experienced. That is, people who have experienced strong earthquakes judge them more likely while those who have not judge them less likely - relative to actual probabilities. Finally, format changes alter people's decisions. That is people treat '1 in 10,000' as different from 0.01% despite their mathematical equivalence. Such effects fall under the broad term framing, which describes how different framings of the same event alter decisions. In particular, people's attitude to risk depends significantly on how scenarios are described. We examine the effect of biases on the communication of change in risk. South Australian participants gave responses to scenarios describing familiar (bushfire) or unfamiliar (earthquake) risks. While bushfires are rare in specific locations, significant fire events occur each year and are extensively covered. By comparison, our study location (Adelaide) last had a M5 quake in 1954. Preliminary results suggest the description

    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

  4. The role of stakeholder involvement in risk communication

    Inviting stakeholders to be part of the decision making process in risk analysis and management improves the likelihood that the resulting decision will be accepted. Unfortunately, early public involvement may compromise, however, the objective of efficient and effective risk reduction or violate the principle of fairness. Another problem is that the public consists of many groups with different value structures and preferences. Without a systematic procedure to reach consensus on values and preferences, the public's position often appears as unclear. Participatory processes are thus needed that combine technical expertise, rational decision making, and public values and preferences. The recent report by the National Academy of Sciences encourages risk professionals to foster citizen participation and public involvement in risk management. The report emphasizes the need for a combination of assessment and dialogue which the authors have framed the 'analytic-deliberative' approach. The popularity associated with the concepts of two-way-communication, trust-building, and citizen participation, however, obscures the challenge of how to put these noble goals into practice and how to ensure that risk management reflects competence, efficiency, and fair burden sharing. This paper discusses the potential and requirements for stakeholder participation in the field of risk management and communication. (orig.)

    The public concern about electromagnetic field (EMF) exposure varies due to different reasons. A part of them are connected with the better and higher quality of information that people receive from science, media, Internet, social networks, industry, but others are based on good communication programs performed by the responsible institutions, administration and persons. Especially, in Bulgaria, public concern follows interesting changes, some of them in correlation with the European processes of concern, but others following the economic and political processes in the country. Here, we analyze the dynamics of the public concern over the last 10 years. Our explanation of the decrease of the people's complaints against EMF exposure from base stations for mobile communication is as a result of our risk communication program that is in implementation for >10 years.

    One of the biggest advantages of the digital low level rf (LLRF) system is its flexibility. Owing to the recent rapid progress in digital devices (such as ADCs and DACs) and telecommunication devices (mixers and IQ modulators), digital LLRF system becomes popular in these 10 years. The J-PARC linac LLRF system adopted cPCI crates and FPGA based digital feedback system. Since the LLRF control of the normal conducting cavities are more difficult than super conducting cavities due to its lower Q values, fast processing using the FPGA was the essential to the feedback control. After the successful operation of J-PARC linac LLRF system, we developed the STF (ILC test facility in KEK) LLRF system. Since the klystron drives eight cavities in STF phase 1, we modified the FPGA board. Basic configuration and the performances of these systems are summarized. The future R and D projects (ILC and ERL) is also described from the viewpoints of LLRF. (author)

    A scoping level evaluation of polyethylene encapsulation and vitreous waste forms for safe storage of mixed low-level waste was performed. Maximum permissible radionuclide concentrations were estimated for 15 indicator radionuclides disposed of at the Hanford and Savannah River sites with respect to protection of the groundwater and inadvertent intruder pathways. Nominal performance improvements of polyethylene and glass waste forms relative to grout are reported. These improvements in maximum permissible radionuclide concentrations depend strongly on the radionuclide of concern and pathway. Recommendations for future research include improving the current understanding of the performance of polymer waste forms, particularly macroencapsulation. To provide context to these estimates, the concentrations of radionuclides in treated DOE waste should be compared with the results of this study to determine required performance

    Both sea dumping and land isolation are planned to be accomplished for low level waste disposal in Japan. The conceptual design of land isolation facilities has been completed, and site selection will presently get underway. With respect to ocean dumping, safety surveys are being performed along the lines of the London Dumping Convention and the Revised Definitions and Recommendations of the IAEA, and the review of Japanese regulations and applicable criteria is being expedited. This paper discusses the present approach to waste solidification practices in Japan. It reports that the bitumen solidification process and the plastic solidification process are being increasingly used in Japan. Despite higher investment costs, both processes have advantages in operating cost, and are comparable to the cement solidification process in overall costs

    A benefit born as an inheritance from low-level radioactive waste is considered. In the present study, a direct economic scale of application of radiation in Japanese industry, agriculture and medicine is taken as parameter for quantifying the size of benefit. In 2006, the economic scale is about 21 billion dollars (b$) for industry, 2.5b$ for agriculture and 14b$ for medicine. Economic scale covered the all fields is totaled 37b$. Due to those benefit, one can drive a car and play an internet, pleasure the dinning food. Diagnosis and treatment by nuclear medicine can possible to survive the millions of lives and resulting in improving the quality of life, decreasing pain and suffering. However, most Japanese (80%>) may not aware those benefits to date. This report is prepared for aiming at disseminating those benefits to our peoples. (author)

    1995-01-01

    In the 1980's the nuclear industry began focusing a great deal of attention on minimizing the volume of low level radioactive waste (LLW) that required disposal. This was driven by several factors including rising disposal costs, increased regulatory pressures, and increased pressure from other organizations such as INPO. In the 1990's most utilities are faced with intense competition in the electrical generation market. The survival of a utility is based on their ability to produce electricity by the most efficient and economical means available. Waste management related costs are a substantial portion of most utilities O ampersand M budgets. Disposal site access denial continues to be a major factor in waste management program decision, and the pressures to minimize waste volumes from outside organizations is greater than ever

    Systematic measurements in gamma spectrometry on slightly radioactive samples have led to study low levels existing in the spectra and to develop suitable processing methods. These methods and the advance that they represent in reading sensitivity are now applicable to all types of spectrum. The principles of this automatic reading are briefly summarized, leading to a description of the modifications which proved necessary to increase sensitivity. Three sample spectra are used to illustrate the arguments employed to achieve this result. The conclusions from the corresponding measurements provide a clearer understanding of the quality of the responses obtained during the initial reading. The application of these methods to systematic measurements is considered in the case of atmospheric aerosols. The owerall results obtained since 1969 are presented [fr

    1999-07-01

    Extremely slow introduction of low-level laser therapy into the practice of ophthalmologists is restricted by the lack of good methodological recommendation and modern equipment adopted to the needs of ophthalmology. The most perspective is considered to be further improvement of the methods and the elaboration of the medical equipment, working in several wave bands, combined with magnetotherapy and working with the use of various modes of the modulation of the intensity of the luminous flux. It may be asserted that unlike the mode of continuous radiation, in some cases, the effectiveness of the treatment increases when the modulated light with the frequency of one to a few tens HZ is used. Moreover, the methods are being elaborated, when the modulation frequency of laser light and the biorhythms of man physiologic parameters are synchronized. Very perspective seems the computerization of the treatment process with the simultaneous electrophysiological control of the condition of visual functions.

    2008-03-01

    This formative research study used qualitative methods to test the suitability of messages about botulism for the general public. Nine focus group interviews and 27 cognitive interviews were conducted with diverse audiences to pretest radio, television, and fact sheet messages predicated on a hypothetical terrorist attack using botulinum toxin. Narrative data were collected, transcribed, coded, and analyzed using content domains based on risk and health communication theories. While participants accepted the need for materials, the messages produced contained images and references describing botulism as a toxin-caused illness spread both by food and water contamination as well as by airborne means. The audience's lack of understanding of the term toxin and an imperfect understanding of airborne transmission of a toxic substance meant that some people interpreted botulism as being an infectious disease rather than a type of poisoning. The communication materials did not clearly show how the set of botulism symptoms are unique and described the anti-toxin as "not a cure," thus compounding the audience's misunderstanding. Using models from cognitive and developmental psychology, our findings were interpreted to show that certain terms evoke or elicit long-held conceptual frameworks that lay audiences use to explain medical phenomena. Relevant to botulism, poisoning events are distinct from infectious diseases, but prepared messages did not reinforce these distinctions. Ignoring how people organize preexisting health information when trying to communicate new information is a prescription for failure, especially in a crisis risk communication scenario. Findings from this study have been used by the Centers for Disease Control and Prevention to reformulate pre-event crisis risk communication materials for botulism.

    Low Level Raidation Effects: A Fact Book, prepared by the Society of Nuclear Medicine Subcommittee on the Risks of Low-Level Ionizing Radiation, attempts to examine the health effects of small doses of radiation. For immediate questions, this work provides a well-organized brief summary of recent radiologic data from refereed scientific literature and from the publications of advisory groups such as the National Council of Radiation Protection and Measurement (NCRP), the International Commission on Radiological Protection (ICRP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), and the National Academy of Sciences (NAS). Since it consists almost entirely of tables and graphs from the above-mentioned sources along with summary paragraphs, the Fact Book is very useful in the preparation of lectures. The book is divided into seven sections. Chapter One, Glossary, Units and Conversion Factors, is useful because nearly all data given in the rest of the book is in conventional units and should be converted to SI units for future technical audiences. Chapter 2, Radiobiology, covers the fundamental principles of the field. Chapter 3, Radiation Doses, can be used to help an audience appreciate the relative magnitudes of radiation exposures they may read about or encounter. Chapter 4, Late Somatic Effects of Low Doses of Ionizing Radiation, gives data concerning cancer induction and embryonic effects, and Chapter 5 provides data on genetic effects Chapter 6, Risks, Statistical Facts and Public Perception can be used to compare the risks of radiation exposure with more commonly encountered risks

    1990-01-01

    Those responsible for state and local radon programs often express frustration about the small share of homes that have been tested for radon, and the small share of those with high readings that have been mitigated. Several recent studies have examined how well alternative ways of communicating about radon's risk have accomplished the goals of motivating appropriate testing and mitigation. Unfortunately, the results of these studies have not reached practitioners. This paper is for them. It summarizes the practical implications that are most crucial for planning and implementing an effective radon risk communication program--a program that will motivate people to test for radon and mitigate when radon levels are high, without unduly alarming those whose radon levels are low

However, these do not cover a solution for the technology events that can occur in the industry, government, education, among others. In the technology market there are several models to identify and analyze risks according to relevant aspects of their area of specialty e.g. projects, in software development, communications, information security and business alignment. For this reason, this research conducted an evaluation of risk management activities of the methodologies used mostly to know which of them includes more correspondence with basic elements of IT using a rating scale.

  19. Alcohol impairs predation risk response and communication in zebrafish.

    Directory of Open Access Journals (Sweden)

    Thiago Acosta Oliveira

    Full Text Available The effects of ethanol exposure on Danio rerio have been studied from the perspectives of developmental biology and behavior. However, little is known about the effects of ethanol on the prey-predator relationship and chemical communication of predation risk. Here, we showed that visual contact with a predator triggers stress axis activation in zebrafish. We also observed a typical stress response in zebrafish receiving water from these conspecifics, indicating that these fish chemically communicate predation risk. Our work is the first to demonstrate how alcohol effects this prey-predator interaction. We showed for the first time that alcohol exposure completely blocks stress axis activation in both fish seeing the predator and in fish that come in indirect contact with a predator by receiving water from these conspecifics. Together with other research results and with the translational relevance of this fish species, our data points to zebrafish as a promising animal model to study human alcoholism.

    Low-level radioactive wastes include a broad spectrum of wastes that have different radionuclide concentrations, half-lives, and physical and chemical properties. Standard shallow-land burial practice can provide adequate protection of public health and safety for most low-level wastes, but a small volume fraction (about 1%) containing most of the activity inventory (approx.90%) requires specific measures known as ''greater-confinement disposal'' (GCD). Different site characteristics and different waste characteristics - such as high radionuclide concentrations, long radionuclide half-lives, high radionuclide mobility, and physical or chemical characteristics that present exceptional hazards - lead to different GCD facility design requirements. Facility design alternatives considered for GCD include the augered shaft, deep trench, engineered structure, hydrofracture, improved waste form, and high-integrity container. Selection of an appropriate design must also consider the interplay between basic risk limits for protection of public health and safety, performance characteristics and objectives, costs, waste-acceptance criteria, waste characteristics, and site characteristics. This paper presents an overview of the factors that must be considered in planning the application of methods proposed for providing greater confinement of low-level wastes. 27 refs

    Biological risk management in public health focuses on the impact of outbreaks on health, the economy, and other systems and on ensuring biosafety and biosecurity. To address this broad range of risks, the International Health Regulations (IHR, 2005) request that all member states build defined core capacities, risk communication being one of them. While there is existing guidance on the communication process and on what health authorities need to consider to design risk communication strategies that meet the requirements on a governance level, little has been done on implementation because of a number of factors, including lack of resources (human, financial, and others) and systems to support effective and consistent capacity for risk communication. The international conference on "Risk communication strategies before, during and after public health emergencies" provided a platform to present current strategies, facilitate learning from recent outbreaks of infectious diseases, and discuss recommendations to inform risk communication strategy development. The discussion concluded with 4 key areas for improvement in risk communication: consider communication as a multidimensional process in risk communication, broaden the biomedical paradigm by integrating social science intelligence into epidemiologic risk assessments, strengthen multisectoral collaboration including with local organizations, and spearhead changes in organizations for better risk communication governance. National strategies should design risk communication to be proactive, participatory, and multisectoral, facilitating the connection between sectors and strengthening collaboration.

  3. Progress in violence risk assessment and communication: hypothesis versus evidence.

    Harris, Grant T; Rice, Marnie E

    2015-02-01

    We draw a distinction between hypothesis and evidence with respect to the assessment and communication of the risk of violent recidivism. We suggest that some authorities in the field have proposed quite valid and reasonable hypotheses with respect to several issues. Among these are the following: that accuracy will be improved by the adjustment or moderation of numerical scores based on clinical opinions about rare risk factors or other considerations pertaining to the applicability to the case at hand; that there is something fundamentally distinct about protective factors so that they are not merely the obverse of risk factors, such that optimal accuracy cannot be achieved without consideration of such protective factors; and that assessment of dynamic factors is required for optimal accuracy and furthermore interventions aimed at such dynamic factors can be expected to cause reductions in violence risk. We suggest here that, while these are generally reasonable hypotheses, they have been inappropriately presented to practitioners as empirically supported facts, and that practitioners' assessment and communication about violence risk run beyond that supported by the available evidence as a result. We further suggest that this represents harm, especially in impeding scientific progress. Nothing here justifies stasis or simply surrendering to authoritarian custody with somatic treatment. Theoretically motivated and clearly articulated assessment and intervention should be provided for offenders, but in a manner that moves the field more firmly from hypotheses to evidence.

    Evidence is accumulating for the importance of feelings of risk in explaining cancer preventive behaviours, but best practices for influencing these feelings are limited. The aim of this experimental study was to compare the effects of narrative and non-narrative risk communication about sunbed use on ease of imagination and feelings of cancer risk. A total of 233 female sunbed users in the general Dutch population were randomly assigned to one of three conditions: a narrative message (i.e., personal testimonial), a non-narrative cognitive message (i.e., factual risk information using cognitive-laden words), or a non-narrative affective message (i.e., factual risk information using affective-laden words). Ease of imagination and feelings of risk were assessed directly after the risk information was given (T1). Three weeks after the baseline session, feelings of risk were measured again (T2). The results revealed that sunbed users who were exposed to narrative risk information could better imagine themselves developing skin cancer and reported higher feelings of skin cancer risk at T1. Moreover, ease of imagination mediated the effects of message type on feelings of risk at T1 and T2. The findings provide support for the effects of narrative risk communication in influencing feelings of cancer risk through ease of imagination. Cancer prevention programmes may therefore benefit from including narrative risk information. Future research is important to investigate other mechanisms of narrative information and their most effective content and format. What is already known on this subject? Evidence is growing for the importance of feelings of risk in explaining cancer preventive behaviours. Narratives have increasingly been considered as an effective format for persuasive risk messages and studies have shown narrative risk communication to be effective in influencing cognitive risk beliefs. What does this study add? Increasing understanding of how feelings of cancer

    1979-04-01

    It is now assumed that any exposure to radiaton at low levels of dose carries some risk of deleterious effects. How low this level may be, or the probability or magnitude of the risk, still are not known. Our best scientific knowledge and advice are essential for the protection of the public health, for the effective application of new technologies in medicine and industry and for guidance in the production of nuclear energy. Unless man wishes to dispense with those activities which inevitably involve exposure to low levels of ionizing radiations, he must recognize that some degree of risk to health, however small, exists. A pragmatic appraisal of how man wishes to continue to derive the benefits of health and happiness from such activities involving ionizing radiaton in times of everchanging conditions and public attitudes in our resource-limited society is the task which lies before all of us - all men and women of our society, of science and of medicine, and of law and government - now and in the future

    1965-03-01

    Tube backgrounds of several 2-inch photomultiplier types having S11, 'S' , S13 and S20 cathodes are compared by measuring signal and background pulse height distributions at pulse heights corresponding to a few photo-electrons. The reference signal is generated by means of a β-source and a plexiglass radiator. It is found that comparatively good results are obtained with selected tubes of the EMI types 6097B and 9514B having equivalent dark current dc values down to 10 -12 input lumens. Special interest is devoted to the correlation between the measured tube backgrounds and the dark current dc values of the tubes, as a good correlation between these parameters simplifies the selection of photomultiplier tubes. The equivalent dark currents of the tested tubes extend over the range 10 -12 to 10 -9 input lumens. Although the investigation deals with photomultiplier tubes intended for use in low level Cerenkov detectors it is believed that the results could be valuable in other fields where photomultiplier tubes are utilized for the detection of weak light pulses

  8. Low level radwaste packaging: why not cement

    Wilson, R.B.

    1978-01-01

    Over the past several years many words have been expended in a quest to define a variety of competing radioactive waste immobilization technologies. With the more recent recognition of the technical pitfalls of urea-formaldehyde (UF) a liquid chemical binder considered as optimum less than two years ago, utilities, architect-engineers and systems vendors find themselves in a technology void, awaiting the inevitable breakthrough which will identify the perfect immobilization agent. The culmination of these pressures has brought about the introduction of new immobilization technologies including: one which offers both volume reduction and immobilization in yet another new binder agent; the costly development of highly sophisticated volume reduction systems, the highly-concentrated products from which may pose as-yet unknown immobilization problems; and, the marketing of several new more expensive liquid chemical binders which are reputed to have eliminated the kinds of problems associated with urea-formaldehyde. This paper addresses these issues by coming full circle and arriving back at the initial approach employed for low level radwaste immobilization, the use of cement. Based on an evaluation of the three principal competing immobilization approaches, liquid chemical, bitumen and cement, the merits and drawbacks of each is examined. As will be described, an objective assessment of these competing technologies has resulted in a somewhat surprising conclusion that, while none of the approaches is without disadvantages, cement can be shown to offer the most reliable, versatile long-term solution to today's needs

    This study has been carried out in the radioactive waste management laboratory Sudan Atomic Energy Commission. The main purpose of this work is method development for treatment and conditioning of low level liquid waste in order to improve radiation protection level in the country. For that purpose a liquid radioactive material containing Cs-137 was treated using the developed method. In the method different type of materials (cement, sands, concrete..etc) were tested for absorption of radiation emitted from the source as well as suitability of the material for storage for long time. It was found that the best material to be used is Smsmia concrete. Where the surface dose reduced from 150 to 3μ/h. Also design of storage container was proposed (with specification: diameter 6.5 cm, height 6 cm, placed in internal cylinder of diameter 10.3 cm, height 12.3 cm) and all are installed on the concrete and cement in the cylinder. Method was used in the process of double-packaging configuration. For more protection it is proposed that a mixed of cement to fill the void in addition to the sand be added to ensure low amount of radiation exposure while transport or storage. (Author)

    1985-02-01

    This topical report describes the results of an investigation on the solidification of low-level radioactive waste in polyethylene. Waste streams selected for this study included those which result from advanced volume reduction technologies (dry evaporator concentrate salts and incinerator ash) and those which remain problematic for solidification using contemporary agents (ion exchange resins). Four types of commercially available low-density polyethylenes were employed which encompass a range of processing and property characteristics. Process development studies were conducted to ascertain optimal process control parameters for successful solidification. Maximum waste loadings were determined for each waste and polyethylene type. Property evaluation testing was performed on laboratory-scale specimens to assess the potential behavior of actual waste forms in a disposal environment. Waste form property tests included water immersion, deformation under compressive load, thermal cycling and radionuclide leaching. Recommended waste loadings of 70 wt % sodium sulfate, 50 wt % boric acid, 40 wt % incinerator ash, and 30 wt % ion exchange resins, which are based on process control and waste form performance considerations are reported. 37 refs., 33 figs., 22 tabs

  11. Photomultiplier tubes for Low Level Cerenkov Detectors

    Tube backgrounds of several 2-inch photomultiplier types having S11, 'S' , S13 and S20 cathodes are compared by measuring signal and background pulse height distributions at pulse heights corresponding to a few photo-electrons. The reference signal is generated by means of a {beta}-source and a plexiglass radiator. It is found that comparatively good results are obtained with selected tubes of the EMI types 6097B and 9514B having equivalent dark current dc values down to 10{sup -12} input lumens. Special interest is devoted to the correlation between the measured tube backgrounds and the dark current dc values of the tubes, as a good correlation between these parameters simplifies the selection of photomultiplier tubes. The equivalent dark currents of the tested tubes extend over the range 10{sup -12} to 10{sup -9} input lumens. Although the investigation deals with photomultiplier tubes intended for use in low level Cerenkov detectors it is believed that the results could be valuable in other fields where photomultiplier tubes are utilized for the detection of weak light pulses.

  12. Solid low-level waste forecasting guide

    1995-03-01

    Guidance for forecasting solid low-level waste (LLW) on a site-wide basis is described in this document. Forecasting is defined as an approach for collecting information about future waste receipts. The forecasting approach discussed in this document is based solely on hanford's experience within the last six years. Hanford's forecasting technique is not a statistical forecast based upon past receipts. Due to waste generator mission changes, startup of new facilities, and waste generator uncertainties, statistical methods have proven to be inadequate for the site. It is recommended that an approach similar to Hanford's annual forecasting strategy be implemented at each US Department of Energy (DOE) installation to ensure that forecast data are collected in a consistent manner across the DOE complex. Hanford's forecasting strategy consists of a forecast cycle that can take 12 to 30 months to complete. The duration of the cycle depends on the number of LLW generators and staff experience; however, the duration has been reduced with each new cycle. Several uncertainties are associated with collecting data about future waste receipts. Volume, shipping schedule, and characterization data are often reported as estimates with some level of uncertainty. At Hanford, several methods have been implemented to capture the level of uncertainty. Collection of a maximum and minimum volume range has been implemented as well as questionnaires to assess the relative certainty in the requested data

    Based on a review of risk communication and related literature, including policy material, this paper describes the newly revamped risk management program of the DOE's Office of Civilian Radioactive Waste Management (OCRWM), and some of the risk-related issues being confronted as the high-level waste management program moves forward. It also describes preliminary activities underway in which the OCRWM is developing strategies for risk communication. The authors offer a definition of risk management as comprised by the components of risk assessment and risk communication. The paper explores the discrepant views that experts and nonexperts have with respect to what constitutes a valid risk assessment model. By illustrating differences in the assessment of risk by experts and lay people, the paper demonstrates how these differences can create challenges in communicating risk and making decisions about risk. Finally, the paper discusses ways in which risk communication could be enhance, and elaborates on the OCRWM's commitment to improve its overall risk management efforts

    How effective is visual communication to increase awareness of natural hazards and risks? To answer this research question, we developed a research design that was at the same time an experimental setting and an actual communication effort. Throughout the full length of the 2-years project held in the Ubaye valley (southeastern France), we collaborated with local and regional stakeholders (politicians and technicians). During a consultation phase, the communication context was determined, the audience of the project was defined and finally the testing activity-communication effort was determined. We were offered the opportunity to design an exhibition for the local public library. In a consultation phase that corresponded to the design of the exhibition, the stakeholders contributed to its content as well as helping with the funding of the exhibition. Finally, during the experimentation phase, the stakeholders participated in advertising the activity, gathering of participants and designing the scientific survey. In order to assess the effects of the exhibition on risk awareness, several groups of children, teenagers and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. In addition, the children answered a second post-test 3 months after the visit. Close ended questions addressed the awareness indicators mentioned in the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to risk, and demographics. In addition, the post-test included several satisfaction questions concerning the visual tools displayed in the exhibition. A statistical analysis of the changes between the pre- and post- tests (paired t-test, Wilcoxon signed-rank test and bootstrapping) allowed to verify whether the exhibition had an impact on risk awareness or not. In order to deduce which variable

    This report describes the procedures applicable to siting and licensing of disposal facilities for low-level radioactive wastes. Primary emphasis is placed on those procedures which are required by regulations, but to the extent possible, non-mandatory activities which will facilitate siting and licensing are also considered. The report provides an overview of how the procedural and technical requirements for a low-level waste (LLW) disposal facility (as defined by the Nuclear Regulatory Commission's Rules 10 CFR Parts 2, 51, and 61) may be integrated with activities to reduce and resolve conflict generated by the proposed siting of a facility. General procedures are described for site screening and selection, site characterization, site evaluation, and preparation of the license application; specific procedures for several individual states are discussed. The report also examines the steps involved in the formal licensing process, including docketing and initial processing, preparation of an environmental impact statement, technical review, hearings, and decisions. It is concluded that development of effective communication between parties in conflict and the utilization of techniques to manage and resolve conflicts represent perhaps the most significant challenge for the people involved in LLW disposal in the next decade. 18 refs., 6 figs

    1997-12-01

    Factors such as hazard type and source credibility have been identified as important in the establishment of effective strategies for risk communication. The elaboration likelihood model was adapted to investigate the potential impact of hazard type, information source, and persuasive content of information on individual engagement in elaborative, or thoughtful, cognitions about risk messages. One hundred sixty respondents were allocated to one of eight experimental groups, and the effects of source credibility, persuasive content of information and hazard type were systematically varied. The impact of the different factors on beliefs about the information and elaborative processing examined. Low credibility was particularly important in reducing risk perceptions, although persuasive content and hazard type were also influential in determining whether elaborative processing occurred.

    This study attempts to provide the necessary framework required to make sufficiently informed decisions regarding the safety implications of ice throw. The framework elaborates on how to cope with uncertainties, and how to describe results in a meaningful and useful manner to decision makers. Moreover, it points out the moral, judicial and economical obligations of wind turbine owners such that they are able to minimize risk of ice throws as much as possible. Building on the strength of knowledge as well as accounting for uncertainty are also essential in enabling clear communication with stakeholders on the most important/critical/vital issues. With increasing empirical evidence, one can assign a higher confidence level on the expert opinions on safety. Findings regarding key uncertainties of ice risk assessments are presented here to support the ongoing IEA Wind Task 19's work on creating the international guidelines on ice risk assessment due in 2018 (Krenn et al. 2017)[1-6]. In addition the study also incorporates the findings of a Norwegian information project, which focuses on the ice throw hazard for the public (Bredesen, Flage, Butt, Winterwind 2018)[7-9]. This includes measures to reduce damage and hazard from wind turbines for the general public. Recent theory of risk assessment questions the use of risk criteria for achieving optimum risk reduction and favours the use of the ALARA (as low as reasonably achievable) principle. Given the several practical problems associated with the ALARA approach (e.g. judicial realization), a joint approach, which uses a minimum set of criteria as well as the obligation to meet ALARA is suggested (associated with acceptable cost). The actual decision about acceptance criteria or obligations is a societal one, thus suggestions can be made at best. Risk acceptance, risk perception and risk communication are inextricably linked and should thus never be considered separately. Risk communication can shape risk perception

    Information stored on the world's largest data bank concerning the health of nuclear industry workers is to be handed over to researchers at Birmingham University by the US Department of Energy. The data bank contains detailed information on 300,000 nuclear employees, going back to the 1940s. Such a large sample size will allow the results of a previous study conducted on workers in the US nuclear industry to be verified. That study was concluded in 1978 and showed that the risk estimates set by the International Commission on Radiological Protection (ICRP) were between 10 and 30 times too low. The current ICRP estimate allows workers up to 50mSv of exposure to low level radiation per year. Risk estimates have been derived from data relating to the atomic bombings of Hiroshima and Nagasaki. However in those cases the radiation doses were relatively high but over a short period. In the nuclear industry the doses are lower but are long term and this may account for the apparent anomalies such as the incidence of leukaemia amongst children whose fathers have worked in the nuclear industry compared with that for the children whose fathers received radiation doses from the atomic bombings. It is expected the study will show that low-level radiation is more damaging than has previously been thought. (author)

    Three experiments explore several factors which influence information transmission when warning messages are passed from person to person. In Experiment 1, messages were passed down chains of participants using five different modes of communication. Written communication channels resulted in more accurate message transmission than verbal. In addition, some elements of the message endured further down the chain than others. Experiment 2 largely replicated these effects and also demonstrated that simple repetition of a message eliminated differences between written and spoken communication. In a final field experiment, chains of participants passed information however they wanted to, with the proviso that half of the chains could not use telephones. Here, the lack of ability to use a telephone did not affect accuracy, but did slow down the speed of transmission from the recipient of the message to the last person in the chain. Implications of the findings for crisis and emergency risk communication are discussed. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

  3. Health effects of low-level radiations

    1982-01-01

    Epidemiological surveys have attempted to assess the carcinogenic risk induced by exposure to low doses of ionizing radiation. Such studies are difficult to carry out because the incidence of radiation induced cancers is of only a few per cent, even following relativity large doses, and because there is no way to distinguish radiation induced cancer from the background of natural human cancers; moreover these surveys are exposed to many biases due to relatively small sizes of the populations studied and the difficulties of finding an appropriate control group, of estimating the absorbed doses and of collecting the data. A few national or international expert committees have analysed the available data and evaluated the carcinogenic effects. Their estimations of the risk, are similar and allow one to quantify the carcinogenic risk for doses above 100 rads. The risks of lower doses must be determined by extrapolation from human data at high doses. This extrapolation requires the knowledge of the dose-effect relationship. A linear extrapolation is most common and probably leads to a conservative estimate of the risk. A linear-quadratic function is probably more realistic and in better accordance with most scientific data. However the validity of its use for the estimation of carcinogenic risk is still debated. In experimental animals, the influence of dose-rate is important and some data suggest that this is the same for the carcinogenic effect in human beings. The genetic effects are probably less important than was feared a few years ago. The most important recent observation is the absence of any significant genetic effect in the progeny of the survivors of the A. bombs in Hiroshima and Nagasaki. This allows a conservative estimate of the maximum genetic risk for human beings [fr

    Risk management has become a dominant concern of public policy and the ability of government to anticipate the strength and focus of public concerns remains weak. The Social Amplification of Risk Framework (SARF) was designed to assist in this endeavor. It aims to facilitate a greater understanding of the social processes that can mediate between a hazard event and its consequences. SARF identifies categories of mediator/moderator that intervene between risk event and its consequences and suggests a causal and temporal sequence in which they act. Information flows first through various sources and then channels, triggering social stations of amplification, initiating individual station of amplification and precipitating behavioral reactions. The International Risk Governance Council Framework is an interdisciplinary and multilevel approach, linking risk management and risk assessment sphere through communication. This study aims to identify categories of mediator/moderator that intervene between the risk event and its consequences, using a survey on earthquake risk perception addressing population of Bucharest city. Romania has a unique seismic profile in Europe, being the country with the biggest surface affected in case of a serious earthquake. Considering the development of the urban area that took place in the last two decades and the growing number of inhabitants, Bucharest is the largest city in Romania and is exposed to extensive damages in case of an earthquake. The sociological survey has been conducted in December 2009 on a representative sample of the Bucharest population aged 18 and over (N=1376) using one stage sampling design. We used a stratified sample method shearing the investigated populations in six layers according to the six sectors of Bucharest. The respondents were selected using random digit dialling method (RDD) and the questionnaires were administered by research staff with computer assisted telephone interviewing method (CATI). The

    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.

  6. Nuclear power and low level radiation hazards

    Even in the future, nuclear power is expected to contribute less than 1/10th of the present total population exposure to man-made radiation. By the best estimates available, the current health risks of nuclear power generation appear to be much less than those associated with the major alternative sources of energy, with the exception of natural gas which is about equally safe. Uncertainties concerning the radiation risks from nuclear power, from medical x-rays and from the effects of reduced ventillation to conserve heat appear to be less than those associated with estimates of risks from the use of coal and various other sources of energy. This is in part because of the large amount of effort devoted to studies of radiation effects. The benefits in terms of current life expectancy associated with any of the conventional or unconventional methods of power production appear to greatly outweigh the associated current health hazards.

    Population-level compliance with health protective behavioral advice to prevent and control communicable disease is essential to optimal effectiveness. Multiple factors affect perceptions of trustworthiness, and trust in advice providers is a significant predeterminant of compliance. While competency in assessment and management of communicable disease risks is critical, communications competency may be equally important. Organizational reputation, quality of stakeholder relationships and risk information provision strategies are trust moderating factors, whose impact is strongly influenced by the content, timing and coordination of communications. This article synthesizes the findings of 2 literature reviews on trust moderating communications and communicable disease prevention and control. We find a substantial evidence base on risk communication, but limited research on other trust building communications. We note that awareness of good practice historically has been limited although interest and the availability of supporting resources is growing. Good practice and policy elements are identified: recognition that crisis and risk communications require different strategies; preemptive dialogue and planning; evidence-based approaches to media relations and messaging; and building credibility for information sources. Priority areas for future research include process and cost-effectiveness evaluation and the development of frameworks that integrate communication and biomedical disease control and prevention functions, conceptually and at scale.

    Recent estimates of the genetic effects of radiation by two widely recognized committees (BEIR III and UNSCEAR 1977) are based to a large extent on data collected in mice using either the specific-locus method or the approach of empirically determining the nature and extent of radiation-induced genetic damage to the skeleton. Both committees made use of doubling-dose and direct methods of estimating genetic hazard. Their estimates can be applied to assessments of risk resulting from medical irradiation in terms both of risk to the population at large and to the individual

  9. Low-level radioactive waste treatment technology. Low-level radioactive waste management handbook series

    International Nuclear Information System (INIS)

    1984-07-01

    Each generator of low-level radioactive waste must consider three sequential questions: (1) can the waste in its as-generated form be packaged and shipped to a disposal facility; (2) will the packaged waste be acceptable for disposal; and (3) if so, is it cost effective to dispose of the waste in its as-generated form. These questions are aimed at determining if the waste form, physical and chemical characteristics, and radionuclide content collectively are suitable for shipment and disposal in a cost-effective manner. If not, the waste management procedures will involve processing operations in addition to collection, segregation, packaging, shipment, and disposal. This handbook addresses methods of treating and conditioning low-level radioactive waste for shipment and disposal. A framework is provided for selection of cost-effective waste-processing options for generic categories of low-level radioactive waste. The handbook is intended as a decision-making guide that identifies types of information required to evaluate options, methods of evaluation, and limitations associated with selection of any of the processing options

  10. Communicating and Visualizing Erosion-associated Risks to Infrastructure

    2016-04-01

    Soil erosion is a major problem worldwide, affecting agriculture, the natural environment and urban areas through its impact on flood risk, water quality, loss of nutrient-rich upper soil layers, eutrophication of water bodies, sedimentation of waterways and sediment-related damage to roads, buildings and infrastructure such as water, gas and electricity supply networks. This study focuses on risks to infrastructure associated with erosion and the interventions needed to reduce those risks. Deciding on what interventions to make means understanding better which parts of the landscape are most susceptible to erosion and which measures are most effective in reducing it. Effective ways of communicating mitigation strategies to stakeholders such as farmers, land managers and policy-makers are then essential if interventions are to be implemented. Drawing on the Decision-Support Matrix (DSM) approach which combines a set of hydrological principles with Participatory Action Research (PAR), a decision-support tool for Communicating and Visualizing Erosion-Associated Risks to Infrastructure (CAVERTI) was developed. The participatory component was developed with the Wear Rivers Trust, focusing on a case-study area in the North East of England. The CAVERTI tool brings together process understanding gained from modelling with knowledge and experience of a variety of stakeholders to address directly the problem of sediment transport. Development of the tool was a collaborative venture, ensuring that the problems and solutions presented are easily recognised by practitioners and decision-makers. This recognition, and ease of access via a web-based interface, in turn help to ensure that the tools get used. The web-based tool developed helps to assess, manage and improve understanding of risk from a multi-stakeholder perspective and proposes solutions to problems. We argue that visualization and communication tools co-developed by researchers and stakeholders are the best means

    The author outlines the evidence for genetic effects. The incidence of congenital abnormalities, stillbirths and child deaths has been examined in 70,000 pregnancies in Hiroshima and Nagasaki and compared with pregnancies in an unirradiated control group. No difference was detected in incidence of congenital abnormalities of stillbirths, but there was a small insignificant increase in child deaths when both parents were exposed. The number of children born with chromosome aberrations was slightly higher, but insignificant in the exposed group compared with controls. However, surveys of congenital malformations in children of radiologists and in children of Hanford workers suggest a genetic effect of radiation. Absolute and relative methods of calculating risks and the ICRP risk factor is also briefly discussed. (U.K.)

    Full Text Available Problem: In the aftermath of Typhoon Haiyan, the World Health Organization (WHO Representative Office in the Philippines had no social media presence to share timely, relevant public health information. Context: Risk communication is essential to emergency management for public health message dissemination. As social media sites, such as Facebook, are popular in the Philippines, these were adopted for risk communication during the response to Haiyan. Action and outcome: The WHO Representative Office in the Philippines established Facebook, Twitter and Instagram accounts. Thirty days after these social medial channels were established, a gradual increase in followers was observed. Facebook saw the largest increase in followers which occurred as posted content gradually evolved from general public health information to more pro-active public health intervention and preparedness messaging. This included information on key health interventions encouraging followers to adopt protective behaviours to mitigate public health threats that frequently occur after a disaster. Lessons learnt: During the response to Haiyan, creating a social media presence, raising a follower base and developing meaningful messages and content was possible. This event underscored the importance of building a social media strategy in non-emergency times and supported the value of developing public health messages and content that both educates and interests the general public.

    The Nevada Risk Assessment/Management Program (NRAMP) is part of a national effort by the U.S. Department of Energy (DOE) to develop new sources of information and approaches to risk assessment, risk management, risk communication and public outreach as these objectives relate to the ecological and human health effects of radioactive and hazardous material management and site remediation activities. This paper reviews the innovation behind the NRAMP project and presents a synopsis of the NRAMP effort which occurred from 1995 to 2000. The primary goals of the DOE in awarding the cooperative agreement establishing NRAMP were to (I) use a risk-based approach to evaluate the consequences of alternative actions in DOE's Environmental Remediation Programs at sites in Nevada and (2) use a neutral and credible institution outside the DOE to perform the risk assessments and contribute to public education about environmental management issues at the Nevada Test Site.

    North Carolina will be the host state for a low-level radioactive waste (LLRW) disposal facility serving the Southeast Compact for 20 yr beginning in 1993. Primary responsibility for the project rests with the North Carolina Low-Level Radioactive Waste Management Authority, a citizen board. The North Carolina project embodies a unique combination of factors that places the authority in a position to exercise technical leadership in the LLRW disposal field. First, the Southeast Compact is the largest in the United States in terms of area, population, and waste generation. second, it is in a humid rather than an arid region. Third, the citizens of the state are intensely interested in preserving life style, environment, and attractiveness of the region to tourists and are especially sensitive to the presence of waste facilities of any kind. Finally, disposal rules set by the Radiation Protection Commission and enforced by the Radiation Protection Section are stricter than the U.S. Nuclear Regulatory Commission's 10CFR61. These four factors support the authority's belief that development of the facility cannot be based solely on engineering and economics, but that social factors, including perceptions of human risk, concerns for the environment, and opinions about the desirability of hosting a facility, should be integral to the project. This philosophy guides the project's many technical aspects, including site selection, site characterization, technology selection and facility design, performance assessment modeling, and waste reduction policies. Each aspect presents its own unique problems

    Although the biological effects of ionizing radiation are probably better known than those of any other physical or chemical agent in the environment, our information about such effects has come from observations at doses and dose rates which are orders of magnitude higher than natural background environmental radiation levels. Whether, therefore biological effects occur in response to such low levels can be estimated only by extrapolation, based on assumptions about the dose-effect relationship and the mechanisms of the effects in question. Present knowledge suggests the possibility that several types of biological effects may result from low-level irradiation. The induction of heritable genetic changes in germ cells and carcinogenic changes in somatic cells are considered to be the most important from the standpoint of their potential threat to health. On the basis of existing data, it is possible to make only tentative upper limit estimates of the risks of these effects at low doses. The estimates imply that the frequency of such effects attributable to exposure at natural background radiation levels would constitute only a small fraction of their natural incidence. 148 references

    Coastal communities around the world face significant and growing flood risks that require an accelerating adaptation response, and fine-resolution urban flood models could serve a pivotal role in enabling communities to meet this need. Such models depict impacts at the level of individual buildings and land parcels or "street level" - the same spatial scale at which individuals are best able to process flood risk information - constituting a powerful tool to help communities build better understandings of flood vulnerabilities and identify cost-effective interventions. To measure understanding of flood risk within a community and the potential impact of street-level models, we carried out a household survey of flood risk awareness in Newport Beach, California, a highly urbanized coastal lowland that presently experiences nuisance flooding from high tides, waves and rainfall and is expected to experience a significant increase in flood frequency and intensity with climate change. Interviews were completed with the aid of a wireless-enabled tablet device that respondents could use to identify areas they understood to be at risk of flooding and to view either a Federal Emergency Management Agency (FEMA) flood map or a more detailed map prepared with a hydrodynamic urban coastal flood model (UCI map) built with grid cells as fine as 3 m resolution and validated with historical flood data. Results indicate differences in the effectiveness of the UCI and FEMA maps at communicating the spatial distribution of flood risk, gender differences in how the maps affect flood understanding, and spatial biases in the perception of flood vulnerabilities.

    Last October, in a landmark case, six scientists and a government official associated with the Italian National Commission for the Forecast and Prevention of Major Risks were found guilty of multiple counts of manslaughter. The trial followed a magnitude 6.3 earthquake near the Italian city of L'Aquila that killed 309 people in April 2009. The alleged crime was not a failure to predict the earthquake, but rather one of inadequately communicating the level of risk, and, presumably in the view of the judge, deliberate obfuscation. Risk communication is about providing the public with information needed to minimise injury, loss of life and damage to property. Mostly, even when well executed, this is, at best, only partially successful. The usual outcome is a public who, despite warnings and for any number of reasons, do not undertake protective behaviour. Nevertheless, despite the difficulty of motivating behavioural change, the public deserve correct and objective information. The L'Aquila situation is not without precedent: on June 25, 1997, a major dome collapse of the Soufrière Hills Volcano on the Caribbean Island of Montserrat killed 19 people within a designated exclusion zone. At the inquest, the advice provided by the scientists involved with the monitoring and risk assessment of the volcano was closely scrutinised. In the end, however, the scientists were not implicated in the deaths and the advice they provided was not challenged. The scientists on Montserrat, like those of the Major Risk Commission in Italy, had come under great pressure to bend their science to the social and political needs of the island; unlike the scientists on trial in Italy, they resisted. Similar questions were posed of fire authorities and scientists after the 2009 bushfires (wildfires) in Victoria, Australia, and the death of 173 people. A longstanding Australian bushfire community safety strategy was the 'prepare, stay and defend [homes], or leave early policy'. It arose from

    For more than a decade, social science studies indicate that there is little or no correlation between the provision of scientific information about geohazards and risks and the adaptive changes in individual or community behaviour that would reduce risk. Bridging that gap to effectively convey hazard science 'the last mile' to those communities at risk raises a number of ethical issues about the role and responsibilities of geoscientists as communicators. Those issues emerge from a methodological shift away from the dominant interpretation of seismic risk communication as a transfer of scientific facts to "the public", towards more inclusive transdisciplinary communication strategies that incorporate peer-role models, adopt social network-based strategies and directly engage with communities in motivating preparedness actions. With this methodological shift comes ethical dilemmas. What are the target-groups that should be prioritised? What are the professional expectations and levels of personal engagement required of geo-communicators? How able and willing are geoscientists to include other forms of knowledge (e.g. from local communities or other disciplines)? What media formats can reconcile argumentative, informational "matters of fact" with sociocultural and psychological "matters of concern"? How should scientists react to political controversies related to risk mitigation and its communication? In the context of these ethical concerns, many geoscientist struggle to switch from conventional communication modes in which they are the technical 'experts' to more community-centered, participatory modes of public engagement. We examine this research question through a case study on seismic risk communication challenges in Istanbul, a megacity with one of the highest seismic vulnerabilities in the world. Currently, there are few formal mechanisms to facilitate interchange between academic geoscientists and the general public in Istanbul. In order to reduce the city

  6. From science to decision-making: taking the risk to communicate on risks

    Geoscientists and decision-makers have the same responsibility toward the society: reducing the damaging consequences induced by natural phenomena. They have to work together, geoscientists to improve the knowledge and decision-makers to take the "best" decision, both to design and implement balanced solutions, both to communicate. Feedback shows that if the collaboration between them has already improved, a lot has still to be done, especially in terms of communication; endless litany, geoscientists don't communicate in the right way! In a hyperspecialized technological and segmented society with sophisticated methods of communication, geoscientists don't use appropriate tools and terminology. It's true, and a lot of examples can be shown that highlight this! Risks is based on complex concepts, on notions that are poorly understood, even by scientists themselves, especially the concepts of probability and occurrence of phenomena. But the problem rest as well on the role and on the responsibility of the geoscientists. Risk management experts address geosciences and technology to identify problems and define protection, including prohibitive measures (such as not allowing building in hazardous areas). Policy makers and local planners want to know where to develop territories. On one hand the identification of problems, on the other hand the needs of solutions. Dialectic is not the same. When responsibility, money and image are the three main pillars of decision-making, long-term modeling and uncertainty, are the basic ones for geosciences. In our participative democracies people want to be actor of the development of their own territories; they want more freedom, more protection and less tax. Face to unrealistic political answers geoscientists have to explain and convince. It's not possible to gain on everything and some are going to loose. Shall geoscientists let decision-makers communicate on topics they hardly understand? No. Shall geoscientists communicate on

    PRESTO (Prediction of Radiation Effects from Shallow Trench Operations) is a computer code developed under US Environmental Protection Agency (EPA) funding to evaluate possible health effects from shallow land burial trenches. The model is intended to be generic and to assess radionuclide transport, ensuing exposure, and health impact to a static local population for a 1000-y period following the end of burial operations. Human exposure scenarios considered by the model include normal releases (including leaching and operational spillage), human intrusion, and site farming or reclamation. Pathways and processes of transit from the trench to an individual or population inlude: groundwater transport, overland flow, erosion, surface water dilution, resuspension, atmospheric transport, deposition, inhalation, and ingestion of contaminated beef, milk, crops, and water. Both population doses and individual doses are calculated as well as doses to the intruder and farmer. Cumulative health effects in terms of deaths from cancer are calculated for the population over the thousand-year period using a life-table approach. Data bases are being developed for three extant shallow land burial sites: Barnwell, South Carolina; Beatty, Nevada; and West Valley, New York
