    Full Text Available Radiological consequences of the accident at the Chernobyl NPP were recently revisited by the UN Chernobyl Forum (2003-2005 and UNSCEAR (2005-2008. For the first time environmental impacts were considered in detail, including radioactive contamination of terrestrial and aquatic environments, application and effectiveness of countermeasures and effects on biota. Updated dosimetric data were presented for more than half a million of emergency and recovery operation workers, about 100 million inhabitants of the three most affected countries, Belarus, the Russian Federation and Ukraine, and for 500 million inhabitants of other European countries. Several hundred of the emergency workers received high radiation doses; of whom 28 persons died in 1986 due to acute radiation sickness. Children at the time of the accident, who drank milk with high levels of radioactive iodine, received high doses to the thyroid. Since early 1990s there was the dramatic increase in thyroid cancer incidence among them. Also in 1990s there was some increase of leukaemia in most exposed workers. The UN Chernobyl Forum concluded that severe social and economic depression of the affected regions and associated psychological problems of the general public and the workers had become the most significant problem. The vast majority of the population need not live in fear of serious health consequences from the Chernobyl accident.

    This new Greenpeace report estimates that the full consequences of the Chernobyl disaster could top a quarter of a million cancers cases and nearly 100,000 fatal cancers. It reports that the report involved 52 respected scientists and includes information never before published in English. It challenges the International Atomic Energy Agency Chernobyl Forum report, which predicted 4,000 additional deaths attributable to the accident as a gross simplification of the real breadth of human suffering. Their data, based on Belarus national cancer statistics, predicts approximately 270,000 cancers and 93,000 fatal cancer cases caused by Chernobyl. The report also concludes that on the basis of demographic data, during the last 15 years, 60,000 people have additionally died in Russia because of the Chernobyl accident, and estimates of the total death toll for the Ukraine and Belarus could reach another 140,000. The report also looks into the ongoing health impacts of Chernobyl and concludes that radiation from the disaster has had a devastating effect on survivors; damaging immune and endocrine systems, leading to accelerated ageing, cardiovascular and blood illnesses, psychological illnesses, chromosomal aberrations and an increase in foetal deformations.

    The Chief Nursing Officer's recent review of mental health nursing called for the widespread involvement of mental health service users in the education of mental health nurses. This paper describes an innovative project that involved mental health service users in the education of pre-registration mental health nursing students through an online discussion forum that blended e-learning with enquiry-based learning (EBL). The findings of an evaluation are presented, drawing on quantitative and qualitative methods. Overall, the project was a success with students and service users engaging in online discussions on a range of issues. EBL presentations demonstrated understanding of the service user experience and students reflected on implications for clinical practice. All participants would take part again and recommend the online forum to others. Analysis of activity data revealed different levels and styles of student involvement. Limitations in communication skills appeared to limit student participation, alongside logistical difficulties, whereas the service users eagerly utilised the forum. Potential implications for healthcare education are discussed and recommendations made for developments in user-led e-learning and further research.

    1991-04-20

    This article looks at daily life in the Northern Ukraine, where the fallout effects from the Chernobyl nuclear reactor accident were felt most keenly. High levels of radioactive iodine 131, strontium 90 and caesium 137 are still present five years on and the health of the population, including those evacuated from the exclusion zones, is at risk from leukaemia and thyroid problems, especially among children. Other worrying reports suggest the occurence of a new disease, ''Chernobyl AIDs'', in which sufferers' immune systems are depressed. Other major outstanding problems include the integrity of the concrete sarcophagus enclosing the damaged reactor, and the continued consumption of locally grown contaminated food due to government inadequacies in supplying ''clean'' equivalents.

    The Chernobyl disaster on April 26th, 1986, led to the emission of radioactive substances such as iodine-131 and radioactive cesium. As the Soviet Union did not control food distribution and intake, residents were exposed to high levels of internal radiation, leading to the internal radiation exposure of the thyroid gland by iodine-131. As a result, the number of people who had thyroid cancer increased drastically among those who had been under 15 years old at the time of the accident. The ag...

    The Chernobyl disaster on April 26th, 1986, led to the emission of radioactive substances such as iodine-131 and radioactive cesium. As the Soviet Union did not control food distribution and intake, residents were exposed to high levels of internal radiation, leading to the internal radiation exposure of the thyroid gland by iodine-131. As a result, the number of people who had thyroid cancer increased drastically among those who had been under 15 years old at the time of the accident. The age predilection is about to move to 25 or older. However, there has been no scientific evidence of impacts for solid tumor other than thyroid cancer, leukemia, benign diseases, or inheritance including unborn babies. On the other hand, the accident was thought to have caused social unrest and mental damage which had far more impact than that caused by radiation exposure. In this paper, we would like to summarize the impacts on the health of the people in Chernobyl compared to those caused by the accident at the Fukushima Daiichi Nuclear Power Plant.

  2. Mental health consequences of the Chernobyl disaster.

    Science.gov (United States)

    Bromet, Evelyn J

    2012-03-01

    The psychosocial consequences of disasters have been studied for more than 100 years. The most common mental health consequences are depression, anxiety, post-traumatic stress disorder, medically unexplained somatic symptoms, and stigma. The excess morbidity rate of psychiatric disorders in the first year after a disaster is in the order of 20%. Disasters involving radiation are particularly pernicious because the exposure is invisible and universally dreaded, and can pose a long-term threat to health. After the Chernobyl disaster, studies of clean-up workers (liquidators) and adults from contaminated areas found a two-fold increase in post-traumatic stress and other mood and anxiety disorders and significantly poorer subjective ratings of health. Among liquidators, the most important risk factor was severity of exposure. In general population samples, the major risk factor was perceived exposure to harmful levels of radiation. These findings are consistent with results from A-bomb survivors and populations studied after the Three Mile Island nuclear power plant accident. With regard to children, apart from findings from ecological studies that lack direct data on radiation or other teratologic exposures and local studies in Kiev, the epidemiologic evidence suggests that neither radiation exposure nor the stress of growing up in the shadow of the accident was associated with emotional disorders, cognitive dysfunction, or impaired academic performance. Thus, based on the studies of adults, the Chernobyl Forum concluded that mental health was the largest public health problem unleashed by the accident. Since mental health is a leading cause of disability, physical morbidity, and mortality, health monitoring after radiation accidents like Fukushima should include standard measures of well-being. Moreover, given the comorbidity of mental and physical health, the findings support the value of training non-psychiatrist physicians in recognizing and treating common mental

    The contents of Chernobyl Record have taken 14 years to compile and this period of time was necessary to enable information to be released from Soviet sources, measurements to be made in the environment, for estimation of radiation doses and for follow-up of the health of population groups which had been exposed. This time frame also includes the 10th anniversary conferences and the completion of joint projects of the European Commission, Ukraine, Belarus and the Russian Federation. It has also enabled me to visit the power plant site, Chernobyl town and Pripyat relatively soon after the accident and also some 10 years later: December 1987 and June 1998. Without such visits some of the photographs in this Record could not have been obtained. Information is also contained in these pages of comparisons of various aspects of the Chernobyl accident with data from the Three Mile Island accident in the USA in 1979, the Hiroshima and Nagasaki atomic bombs, the highly contaminated Techa river area in the Urals in Russia and the accident in Tokaimura, Japan in 1999. The first two chapters are introductory in that they describe terminology which is necessary for an understanding of the remaining chapters. Chapters 3-6 describes the early events: including those leading up to the explosion and then what followed in the immediate aftermath. Chapters 7-8 describe the Sarcophagus and the past and future of nuclear power for electricity generation, including the future of the Chernobyl power station. Chapters 9-11 consider the radiation doses received by various populations, including liquidators, evacuees and those living on contaminated territories: and the contamination of milk by {sup 131}I, and the contamination of other parts of the food chain by {sup 137}Cs.

    The blame for the 1986 Chernobyl disaster has been variously attributed to the operating personnel, the plant management, the design of the reactor, and the lack of adequate safety information in the Soviet nuclear industry. This paper considers a number of design faults, operational shortcomings and human errors that combined in the accident. It examines the sequence of events leading up to the accident, design problems in the reactor and cooling rods, and the course of the accident itself. It considers the ergonomics aspects, and expresses the view that the main cause of the accident was inadequate human-machine interaction. Finally, it stresses the continuing inadequacies of the Soviet nuclear system, and emphasizes that unless the ergonomics lessons are fully learned, a similar disaster could still occur.

Material and Methods. 237 people were exposed during the accident, 134 of them were diagnosed with ARS. Dynamic observation implies a thorough annual examination in a hospital. Results. In the first 1.5-2 years after the ARS mean group indices of peripheral blood have returned to normal. However, many patients had transient expressed moderate cytopenias. Granulocytopenia, thrombocytopenia, lymphopenia and erythropenia were the most frequently observed things during the first 5 years after the accident. After 5 years their occurences lowered. In 11 patients the radiation cataract was detected. A threshold dose for its development is a dose of 3.2 Gy Long-term effects of local radiation lesions (LRL range from mild skin figure smoothing to a distinct fibrous scarring, contractures, persistently recurrent late radiation ulcers. During all years of observation we found 8 solid tumors, including 2 thyroid cancers. 5 hematologic diseases were found. During 29 years 26 ARS survivors died of various causes. Conclusion. The health of ones with long-term ARS effects is determined by the evolution of the LRL effects on skin, radiation cataracts, hema-tological diseases and the accession of of various somatic diseases, not caused by radiation.

    The Lawrence Livermore National Laboratory Atmospheric Release Advisory Capability (ARAC) responded to the Chernobyl nuclear reactor accident in the Soviet Union by utilizing long-range atmospheric dispersion modeling to estimate the amount of radioactivity released (source term) and the radiation dose distribution due to exposure to the radioactive cloud over Europe and the Northern Hemisphere. In later assessments, after the release of data on the accident by the Soviet Union, the ARAC team used their mesoscale to regional scale model to focus in on the radiation dose distribution within the Soviet Union and the vicinity of the Chernobyl plant. 22 refs., 5 figs., 5 tabs.

    2007-11-01

    The accident at Unit No. 4 of the Chernobyl Nuclear Power Plant on 26 April 1986 presented severe challenges in radiation protection. Early activity measurements defined the contaminated areas in order to determine what persons should be evacuated on the basis of the exposure limit at that time of 100 mSv (10 rem) for accidents. The immediate definition of these areas was accomplished with specially equipped aircraft capable of measuring external gamma-exposure rate and radionuclide spectra. Over time, maps of 137Cs contamination (the most important long-lived radionuclide) have become more and more sophisticated and have been used for further determinations of the control of the consequences of the accident. About 70% of the total release of 137Cs was deposited in Belarus, the Russian Federation, and Ukraine; but there was also widespread deposition throughout the countries of Western Europe. Two atlases of contamination throughout Europe were prepared, and the Russian atlas included data on other radionuclides and on external gamma-exposure rates. The radiocesiums behaved as volatile radionuclides because of the volatility of cesium. In contrast to the typical pattern after nuclear weapons tests, 90Sr behaved only as a refractory element, as its volatile precursors krypton and rubidium had already decayed within the reactor. Nearly all of the refractory elements (strontium, plutonium, etc.) released by the accident were confined to the 30-km zone around the reactor. A proposal is made to develop a more complete atlas of 137Cs deposition from the accident that would include the entire Northern Hemisphere. Water was not an important vector of exposure to human beings following the accident.

  2. Chernobyl birds have smaller brains.

    Directory of Open Access Journals (Sweden)

    Anders Pape Møller

    Full Text Available BACKGROUND: Animals living in areas contaminated by radioactive material from Chernobyl suffer from increased oxidative stress and low levels of antioxidants. Therefore, normal development of the nervous system is jeopardized as reflected by high frequencies of developmental errors, reduced brain size and impaired cognitive abilities in humans. Alternatively, associations between psychological effects and radiation have been attributed to post-traumatic stress in humans. METHODOLOGY/PRINCIPAL FINDING: Here we used an extensive sample of 550 birds belonging to 48 species to test the prediction that even in the absence of post-traumatic stress, there is a negative association between relative brain size and level of background radiation. We found a negative association between brain size as reflected by external head volume and level of background radiation, independent of structural body size and body mass. The observed reduction in brain size in relation to background radiation amounted to 5% across the range of almost a factor 5,000 in radiation level. Species differed significantly in reduction in brain size with increasing background radiation, and brain size was the only morphological character that showed a negative relationship with radiation. Brain size was significantly smaller in yearlings than in older individuals. CONCLUSIONS/SIGNIFICANCE: Low dose radiation can have significant effects on normal brain development as reflected by brain size and therefore potentially cognitive ability. The fact that brain size was smaller in yearlings than in older individuals implies that there was significant directional selection on brain size with individuals with larger brains experiencing a viability advantage.

    Expert Seeker is a computer program of the knowledge-management-system (KMS) type that falls within the category of expertise-locator systems. The main goal of the KMS system implemented by Expert Seeker is to organize and distribute knowledge of who are the domain experts within and without a given institution, company, or other organization. The intent in developing this KMS was to enable the re-use of organizational knowledge and provide a methodology for querying existing information (including structured, semistructured, and unstructured information) in a way that could help identify organizational experts. More specifically, Expert Seeker was developed to make it possible, by use of an intranet, to do any or all of the following: Assist an employee in identifying who has the skills needed for specific projects and to determine whether the experts so identified are available. Assist managers in identifying employees who may need training opportunities. Assist managers in determining what expertise is lost when employees retire or otherwise leave. Facilitate the development of new ways of identifying opportunities for innovation and minimization of duplicated efforts. Assist employees in achieving competitive advantages through the application of knowledge-management concepts and related systems. Assist external organizations in requesting speakers for specific engagements or determining from whom they might be able to request help via electronic mail.

    On april 26, 1986 a major nuclear disaster took place at 1 h 24 min local time, destroying the fourth reactor of the Chernobyl plant. Five years later the consequences of the disaster are still not fully known. Nevertheless the long term future of nuclear energy in the world is uncertain. Questions need to be answered by observing hard facts if emotional attitudes are not to prevail over reality. The reactor and its core were destroyed by an explosion, causing two radioactive jet emissions of iodine 131, followed by caesium 137. Both elements are mainly incorporated in the body via food. The Chernobyl disaster was a consequence of inadequate safety regulations and human error. Enforcement of strict regulations are likely to be highly effective in preventing a further catastrophe. However, governments should consider another possibility. What would be the consequences for public health if a terroristic act deliberately destroyed a nuclear power station.

    2006-04-15

    Twenty years after the Chernobyl disaster, the need for continued study of its far-reaching consequences remains as great as ever. Several million people (by various estimates, from 5 to 8 million) still reside in areas that will remain highly contaminated by Chernobyl's radioactive pollution for many years to come. Since the half-life of the major (though far from the only) radioactive element released, caesium-137 (137Cs), is a little over 30 years, the radiological (and hence health) consequences of this nuclear accident will continue to be experienced for centuries to come. This event had its greatest impacts on three neighbouring former Soviet republics: Ukraine, Belarus, and Russia. The impacts, however, extended far more widely. More than half of the caesium-137 emitted as a result of the explosion was carried in the atmosphere to other European countries. At least fourteen other countries in Europe (Austria, Sweden, Finland, Norway, Slovenia, Poland, Romania, Hungary, Switzerland, Czech Republic, Italy, Bulgaria, Republic of Moldova and Greece) were contaminated by radiation levels above the 1 Ci/km{sup 2} (or 37 kBq/m{sup 2}), limit used to define areas as 'contaminated'. Lower, but nonetheless substantial quantities of radioactivity linked to the Chernobyl accident were detected all over the European continent, from Scandinavia to the Mediterranean, and in Asia. Despite the documented geographical extent and seriousness of the contamination caused by the accident, the totality of impacts on ecosystems, human health, economic performance and social structures remains unknown. In all cases, however, such impacts are likely to be extensive and long lasting. Drawing together contributions from numerous research scientists and health professionals, including many from the Ukraine, Belarus and the Russian Federation, this report addresses one of these aspects, namely the nature and scope of the long-term consequences for human health.

    Because of its public health, ecological and industrial consequences, the Chernobyl accident has become a myth which serves as the focus of many fears, justified or not. no one can question the seriousness of the event, but after fifteen years there is still no agreement about the effect it has had or will have on public health. For example, the total number of deaths attributed to Chernobyl varies from less than a hundred to several millions and congenital malformations from negligible to cataclysmic. Effects on public health may be calculated from data on contamination, from the dose received and from the risk, all three of which are likely to be very roughly known; or they may be evaluated on the spot, either by epidemiological studies or by examining medical registers. This report makes an inventory of the different risks and takes stock on them. (N.C.)

    1987-01-01

    From the major accident at Unit 4 of the Chernobyl nuclear power station, a plume of airborne radioactive fission products was initially carried northwesterly toward Poland, thence toward Scandinavia and into Central Europe. Reports of the levels of radioactivity in a variety of media and of external radiation levels were collected in the Department of Energy's Emergency Operations Center and compiled into a data bank. Portions of these and other data which were obtained directly from published and official reports were utilized to make a preliminary assessment of the extent and magnitude of the external dose to individuals downwind from Chernobyl. Radioactive /sup 131/I was the predominant fission product. The time of arrival of the plume and the maximum concentrations of /sup 131/I in air, vegetation and milk and the maximum reported depositions and external radiation levels have been tabulated country by country. A large amount of the total activity in the release was apparently carried to a significant elevation. The data suggest that in areas where rainfall occurred, deposition levels were from ten to one-hundred times those observed in nearby ''dry'' locations. Sufficient spectral data were obtained to establish average release fractions and to establish a reference spectra of the other nuclides in the release. Preliminary calculations indicated that the collective dose equivalent to the population in Scandinavia and Central Europe during the first year after the Chernobyl accident would be about 8 x 10/sup 6/ person-rem. From the Soviet report, it appears that a first year population dose of about 2 x 10/sup 7/ person-rem (2 x 10/sup 5/ Sv) will be received by the population who were downwind of Chernobyl within the U.S.S.R. during the accident and its subsequent releases over the following week. 32 refs., 14 figs., 20 tabs.

    A broad-base review of the N Reactor plant, design characteristics, administrative controls and responses unique to upset conditions has been completed. The review was keyed to Nuclear Regulatory Commission (NRC)-defined issues associated with the Chernobyl accident. Physical features of N Reactor that preclude an accident like Chernobyl include: lack of autocatalytic reactivity insertion (i.e., negative coolant void and power coefficents) and two separate, fast-acting scram systems. Administrative controls in place at N Reactor would effectively protect against the operator errors and safety violations that set up the Chernobyl accident. Several items were identified where further near-term action is appropriate to ensure effectiveness of existing safety features: Resolve a question concerning the exact point at which Emergency Core Cooling System (ECCS) activation by manual actions should be implemented or deferred if automatic ECCS trip fails. Ensure appropriate revision of the Emergency Response Guides and full communication of the correct procedure to all Operations, Safety and cognizant Technology staff. Train reactor operators in the currently recognized significance of the Graphite and Shield Cooling System (GSCS) in severe accident situations and cover this appropriately in the Emergency Response Guides. Complete reviews which establish an independent verification that pressure tube rupture will not propagate to other tubes. 15 refs., 3 tabs.

    Although the Chernobyl nuclear disaster happened in the Soviet Union in 1986, we still do not know how the most affected states - Ukraine and Belarus - have managed this tragedy since independence. Drawing on the concept of cultural trauma, this article compares Chernobyl narratives in Belarus and Ukraine over the past 28 years. It shows that national narratives of Chernobyl differ, representing the varying ways in which the state overcomes trauma. Our understanding of post-communist transformations can be improved by analysing trauma management narratives and their importance for new national identity construction. These narratives also bring new insights to our vision of cultural trauma by linking it to ontological insecurity. The article demonstrates how the state can become an arena of trauma process as it commands material and symbolic resources to deal with trauma. In general, it contributes to a better understanding of how the same traumatic event can become a source of solidarity in one community, but a source of hostility in another.

    A severe accident occurred at the Chernobyl nuclear power plant number 4 in the Soviet Union on April 25, 1986. An explosion released large amounts of radioactive debris, primarily fission products, to the atmosphere. As winds carried debris from the Soviet Union, scientists in Europe and the United States reported detecting fission product activities in air samples. Monitoring by the Tracking Radioactive Atmospheric Contaminants (TRAC) mobile laboratory showed concentrations in the Southeastern United States were well below those considered hazardous. This document provides details of this monitoring effort.

    The principal meeting attended during this trip was the Japan International Tribology Conference Nagoya 1990. The conference encompassed a wide range of topics, including the tribology of ceramics, the tribology in high-performance automobiles, and many aspects of lubrication technology. Associated forums were also held on the tribology of advanced ceramics, on solid lubrication, and on automotive lubricants. Presentations made during the latter forum discussed anticipated trends in engine development and anticipated improvements in lubricants required for the next generation of engines. In addition to meetings, site visits were made to five industrial organizations to discuss ceramic tribology. Nippon Steel Corporation and Toshiba Corporation are both very active in the ceramic area, Nippon Steel from their interest in research on new materials and Toshiba from both an interest in new materials and in support of their work in electronic devices. Two engine manufacturers were also visited, Toyota Motor Corporation, and Nissan Motor Co., Ltd. These companies were somewhat reserved in their discussion of progress in the utilization of ceramics in automobile engines.

  13. 5. Nonmalignant diseases after the Chernobyl catastrophe.

    Science.gov (United States)

    Yablokov, Alexey V

    2009-11-01

    This section describes the spectrum and the scale of the nonmalignant diseases that have been found among exposed populations. Adverse effects as a result of Chernobyl irradiation have been found in every group that has been studied. Brain damage has been found in individuals directly exposed--liquidators and those living in the contaminated territories, as well as in their offspring. Premature cataracts; tooth and mouth abnormalities; and blood, lymphatic, heart, lung, gastrointestinal, urologic, bone, and skin diseases afflict and impair people, young and old alike. Endocrine dysfunction, particularly thyroid disease, is far more common than might be expected, with some 1,000 cases of thyroid dysfunction for every case of thyroid cancer, a marked increase after the catastrophe. There are genetic damage and birth defects especially in children of liquidators and in children born in areas with high levels of radioisotope contamination. Immunological abnormalities and increases in viral, bacterial, and parasitic diseases are rife among individuals in the heavily contaminated areas. For more than 20 years, overall morbidity has remained high in those exposed to the irradiation released by Chernobyl. One cannot give credence to the explanation that these numbers are due solely to socioeconomic factors. The negative health consequences of the catastrophe are amply documented in this chapter and concern millions of people.

    This reports a history and future prospects of the activities by the Student Forum of the Geoinformation Forum Japan. For growths of academic fields, active communications among students and young scientists are indispensable. Several academic communities in geoinformation fields are established by youths and play important roles of building networks over schools and institutes. The networks are expected to be innovative cooperation after the youths achieve their professions. Although academic communities are getting fixed growth particularly in Japan, youths had gotten little opportunities to make contacts with youths themselves. To promote gotten youth activities among geoinformation fields, in 1998, we started a series of programs that named the Student Forum of the Geoinformation Forum Japan involving students and young scientists within the annual conferences, Geoinformation Forum Japan. The programs have provided opportunities to do presentation their studies by posters, some events, and motivations to create networks among students and young scientists. From 2009, some members of our activities set additional conference in west area of Japan. Thus our activities are spread within Japan. As a result of these achievements, the number of youth dedicating to the programs keeps growing. From 2009, it's getting international gradually, however, almost all the participants are still Japanese. To keep and expand the network, we are planning to make some nodes with some Asian youth organizations in the field of geoinformation. This paper is concluded with proposals and future prospects on the Student Forum of the Geoinformation Forum Japan.

  15. Psychological and perceived health effects of the Chernobyl disaster: a 20-year review.

    Science.gov (United States)

    Bromet, Evelyn J; Havenaar, Johan M

    2007-11-01

    The mental health impact of Chernobyl is regarded by many experts as the largest public health problem unleashed by the accident to date. This paper reviews findings reported during the 20-y period after the accident regarding stress-related symptoms, effects on the developing brain, and cognitive and psychological impairments among highly exposed cleanup workers. With respect to stress-related symptoms, the rates of depressive, anxiety (especially post-traumatic stress symptoms), and medically unexplained physical symptoms are two to four times higher in Chernobyl-exposed populations compared to controls, although rates of diagnosable psychiatric disorders do not appear to be elevated. The symptom elevations were found as late as 11 y after the accident. Severity of symptomatology is significantly related to risk perceptions and being diagnosed with a Chernobyl-related health problem. In general, the morbidity patterns are consistent with the psychological impairments documented after other toxic events, such as the atomic bombings of Hiroshima and Nagasaki, the Three Mile Island accident, and Bhopal. With respect to the developing brain of exposed children who were in utero or very young when the accident occurred, the World Health Organization as well as American and Israeli researchers have found no significant associations of radiation exposure with cognitive impairments. Cognitive impairments in highly exposed cleanup workers have been reported by Ukrainian researchers, but these findings have not been independently confirmed. A seminal study found a significant excess death rate from suicide in cleanup workers, suggesting a sizable emotional toll. Given the magnitude and persistence of the adverse mental health effects on the general population, long-term educational and psychosocial interventions should be initiated that target primary care physicians, local researchers, and high risk populations, including participants in ongoing cohort studies.

    International environmental policy requires three kinds of competency: adequate expert knowledge in matters of reactor safety, environmental and health hazards, economic competency, and competency in the social and political sciences, which place issues in their social context and investigate how wills are formed and decision processes are made; finally the desire to draw conclusions from insight gained. But the example of Chernobyl shows that the boundary conditions of environmental policy in eastern Europe are distinct from the ones in western industrial societies. The papers that make up this book document the dialogue between natural science experts, technical experts, social and political science, and active politics. Experts heard are from Germany, Russia and Belarus, as well as from international organizations.

The close agreement obtained between computed and observed distributions lends confidence to estimates of flushing times-fundamental parameters in determining pollutant concentrations. Moreover, this study confirms, to first-order, the estimates of Chernobyl fall-out provided by atmospheric dispersion models.

  1. A 25 year retrospective review of the psychological consequences of the Chernobyl accident.

    2011-05-01

    The Chernobyl Forum Report from the 20th anniversary of the Chernobyl nuclear power plant disaster concluded that mental health effects were the most significant public health consequence of the accident. This paper provides an updated review of research on the psychological impact of the accident during the 25 year period since the catastrophe began. First responders and clean-up workers had the greatest exposure to radiation. Recent studies show that their rates of depression and post-traumatic stress disorder remain elevated two decades later. Very young children and those in utero who lived near the plant when it exploded or in severely contaminated areas have been the subject of considerable research, but the findings are inconsistent. Recent studies of prenatally exposed children conducted in Kiev, Norway and Finland point to specific neuropsychological and psychological impairments associated with radiation exposure, whereas other studies found no significant cognitive or mental health effects in exposed children grown up. General population studies report increased rates of poor self-rated health as well as clinical and subclinical depression, anxiety, and post-traumatic stress disorder. Mothers of young children exposed to the disaster remain a high-risk group for these conditions, primarily due to lingering worries about the adverse health effects on their families. Thus, long-term mental health consequences continue to be a concern. The unmet need for mental health care in affected regions remains an important public health challenge 25 years later. Future research is needed that combines physical and mental health outcome measures to complete the clinical picture.

    ETHOS is a pilot research project supported by the radiation protection research program of the European Commission (DG XII). The project provides an alternative approach to the rehabilitation of living conditions in the contaminated territories of the CIS in the post-accident context of Chernobyl. Initiated at the beginning of 1996, this 3-y project is currently being implemented in the Republic of Belarus. The ETHOS project involves an interdisciplinary team of European researchers from the following institutions: the Centre d'etude sur l'Evaluation de la Protection dans le domaine Nucleaire CEPN (radiological protection, economics), the Institute National d'Agronomie de Paris-Grignon INAPG (agronomy, nature & life management), the Compiegne University of Technology (technological and industrial safety, social trust), and the Mutadis Research Group (sociology, social risk management), which is in charge of the scientific co-ordination of the project. The Belarussian partners in the ETHOS project include the Ministry of Emergencies of Belarus as well as the various local authorities involved with the implementation site. The ETHOS project relies on a strong involvement of the local population in the rehabilitation process. Its main goal is to create conditions for the inhabitants of the contaminated territories to reconstruct their overall quality of life. This reconstruction deals with all the day-to-day aspects that have been affected or threatened by the contamination. The project aims at creating a dynamic process whereby acceptable living conditions can be rebuilt. Radiological security is developed in the ETHOS project as part of a general improvement in the quality of life. The approach does not dissociate the social and the technical dimensions of post-accident management. This is so as to avoid radiological risk assessment and management being reduced purely to a problem for scientific experts, from which local people are excluded, and to take into

    This is an annual report, regularly issued by IPSN, that presents the ecological and health consequences of the Chernobyl Nuclear Accident. The present status of the Chernobyl Nuclear Plant, which Ukraine engaged to stop definitively in year 2000, is summarized. The only reactor unit now in operation is Chernobylsk-3 Reactor which poses two safety questions: evolution of cracks in part of the tubing and behaviour of the pressure tubes. Although, some improvements in the RBMK reactor types were introduced, problems remain that make IPSN to stress the requirement of stopping this NPP completely. In the contaminated territories surrounding Chernobyl incidence rate of infant thyroid cancers continues to grow, reaching values 10 to 100 times higher than the natural rate. In France the IPSN analyzed 60,000 records carried out in 17 sites during May 1986 and April 1989. It was estimated that the individual dose received during 60 years (1986-2046) by the inhabitants of the most affected zone (eastern France) is lower than 1.5 mSv, a value lower than 1% of the natural cosmic and telluric radioactivity exposure for the same period. For the persons assumed to live in the most attacked forests (from eastern France) and nourishing daily with venison and mushrooms the highest estimate is 1 mSv a year. Concerning the 'hot spots', identified in mountains by IPSN and CRIIRAD, the doses received by excursionists are around 0.015 mSv. For an average inhabitant of the country the dose piled up in the thyroid due to iodine-131 fallout is estimated to 0.5-2 mSv for an adult and 6.5-16 mSv for an infant. These doses are 100 to 1000 times lower than the ones to which the infants living in the neighbourhood of Chernobyl are exposed to. The contents of the report is displayed in the following six chapters: 1. Chernobyl in some figures; 2. The 'sarcophagus' and the reactors of the Chernobyl NPP; 3.

    The accident at the Chernobyl, Ukraine, nuclear reactor on 26 April 1986 released large amounts of radiocesium and other radionuclides into the environment, contaminating much of the northern hemisphere, especially Europe. In the vicinity of Chernobyl, at least 30 people died, more than 115,000 others were evacuated, and consumption of milk and other foods was banned because of radiocontamination. At least 14,000 human cancer deaths are expected in Russia, Belarus, and the Ukraine as a direct result of Chernobyl. The most sensitive local ecosystems, as judged by survival, were the soil fauna, pine forest communities, and certain populations of rodents. Elsewhere, fallout from Chernobyl significantly contaminated freshwater and terrestrial ecosystems and flesh and milk of domestic livestock; in many cases, radionuclide concentrations in biological samples exceeded current radiation protection guidelines. Reindeer (Rangifer tarandus) in Scandinavia were among the most seriously afflicted by Chernobyl fallout, probably because their main food during winter (lichens) is an efficient absorber of airborne particles containing radiocesium. Some reindeer calves contaminated with 137Cs from Chernobyl showed 137Cs-dependent decreases in survival and increases in frequency of chromosomal aberrations. Although radiation levels in the biosphere are declining with time, latent effects of initial exposure--including an increased frequency of thyroid and other cancers--are now measurable. The full effect of the Chernobyl nuclear reactor accident on natural resources will probably not be known for at least several decades because of gaps in data on long-term genetic and reproductive effects and on radiocesium cycling and toxicokinetics.

    Full Text Available This article introduces a unique model for public theological conversation and discourse, which was developed by the Concerned Black Clergy of Atlanta (CBC. It was a model developed in response to the problems of poverty, homelessness, and the ‘missing and murdered children’ victimised in Atlanta, Georgia in the United States of America in the early 1980s. It was originally organised to respond to the economic, financial, spiritual, emotional, employment, housing and resource needs of the underserved poor. This unique practice is called forum-ing. The forum meets every Monday morning, except when there is a national holiday. It has operated 30 consecutive years. The forum has a series of presentations, including the opening prayer, self-introductions of each person, a report of the executive director, special presentations from selected community groups, reports, and then questions and answers. The end result is that those attending engage in a process of discourse that enables them to internalise new ideas, approaches, and activities for addressing poverty and injustice in the community. Key to forum-ing for the 21st century is that it is a form of public practical theology rooted and grounded in non-violence growing out of the civil rights movement of the 1950s and 1960s in the United States. The overall purpose of this article is to contribute to the effort of the Faculty of Theology at the University of Pretoria (South Africa to identify those variables that will assist religious leaders in South Africa to develop public conversational spaces to enhance democratic participation. This article presents one model from the African American community in Atlanta, Georgia. The hope is to lift up key variables that might assist in the practical and pastoral theological conversation taking place in South Africa at present.

    The radioactivity of various terrestrial vegetation leaves characteristic of Mediterranean countries has been measured after the Chernobyl accident. In addition, we paid particular attention to lichens and seaweed which are considered as bioindicators of radioactive contamination. Most measurements were performed non-destructively using both coaxial and planar HPGe detectors. For odd mass radionuclides having low energy lines, such as 125Sb or 141Ce the sensitivity of the planar HPGe detector is better than the coaxial detector. The concentration of long-lived fission nuclides remaining three months after the accident were found to be enhanced in needle form leaves and in lichens. The seaweed Sphaerococcus exhibits a strong specific activity for iodine and ruthenium elements and poor concentration for caesium nuclides. The activity ratios of different isotopes of the same element measured in vegetation samples agree well with values found in airborne aerosols by other authors. The activation nuclide 110mAg is found in all samples with the same ratio 110mAg/137Cs = (1.0 +/- 0.2).10(-2) as in the soil deposition.

Two cities of Hiroshima and Nagasaki were destroyed by nuclear blast with about 20 kt TNT equivalent and then approximately 100,000 people have died respectively. On the other hand, the number of acute death is 30 in the Chernobyl nuclear reactor accident. In this chapter, we review health hazards and doses in two historical nuclear incidents of Chernobyl and Tokaimura criticality accident and then understand the feature of the radiation accident in peaceful utilization of nuclear power.

  16. RADIOACTIVE WASTE MANAGEMENT IN THE CHERNOBYL EXCLUSION ZONE - 25 YEARS SINCE THE CHERNOBYL NUCLEAR POWER PLANT ACCIDENT

    Farfan, E.; Jannik, T.

    2011-10-01

    Radioactive waste management is an important component of the Chernobyl Nuclear Power Plant accident mitigation and remediation activities of the so-called Chernobyl Exclusion Zone. This article describes the localization and characteristics of the radioactive waste present in the Chernobyl Exclusion Zone and summarizes the pathways and strategy for handling the radioactive waste related problems in Ukraine and the Chernobyl Exclusion Zone, and in particular, the pathways and strategies stipulated by the National Radioactive Waste Management Program. The brief overview of the radioactive waste issues in the ChEZ presented in this article demonstrates that management of radioactive waste resulting from a beyond-designbasis accident at a nuclear power plant becomes the most challenging and the costliest effort during the mitigation and remediation activities. The costs of these activities are so high that the provision of radioactive waste final disposal facilities compliant with existing radiation safety requirements becomes an intolerable burden for the current generation of a single country, Ukraine. The nuclear accident at the Fukushima-1 NPP strongly indicates that accidents at nuclear sites may occur in any, even in a most technologically advanced country, and the Chernobyl experience shows that the scope of the radioactive waste management activities associated with the mitigation of such accidents may exceed the capabilities of a single country. Development of a special international program for broad international cooperation in accident related radioactive waste management activities is required to handle these issues. It would also be reasonable to consider establishment of a dedicated international fund for mitigation of accidents at nuclear sites, specifically, for handling radioactive waste problems in the ChEZ.

    Various authors have pointed out that humans can become quite adept at deriving phonetic transcriptions from speech spectrograms (as good as 90percent accuracy at the phoneme level). The authors describe an expert system which attempts to simulate this performance. The speech spectrogram expert (spex) is actually a society made up of three experts: a 2-dimensional vision expert, an acoustic-phonetic expert, and a phonetics expert. The visual reasoning expert finds important visual features of the spectrogram. The acoustic-phonetic expert reasons about how visual features relates to phonemes, and about how phonemes change visually in different contexts. The phonetics expert reasons about allowable phoneme sequences and transformations, and deduces an english spelling for phoneme strings. The speech spectrogram expert is highly interactive, allowing users to investigate hypotheses and edit rules. 10 references.

    1998-01-01

    In Sweden the TMI accident was the direct cause to a decision to hold a national referendum on nuclear power on March 23, 1980. The referendum and the subsequent political decision to phase out nuclear power by 2010 to some extent neutralized the issue and nuclear attitudes returned to a mildly positive state. However, the Chernobyl accident in 1986 again changed the scene. Just as the TMI accident had been something of a surprise to many, the Chernobyl accident and its consequences in Scandinavia were not anticipated. Attitudes to nuclear power became quite negative immediately after the accident but they soon resumed their initial mildly positive position again. Even if the radioactive fall-out never reached truly alarming levels authorities in Finland, Norway and Sweden took measures to counteract the effects of radioactivity and to protect the population. This was done in a very heated atmosphere and intense attention was paid by the mass media. Trust in authorities and governments was put to a stringent test during these days 10 years ago. Several psychologists, sociologists and mass media researchers were active from the very beginning to document the events taking place, e.g. by means of surveys of the public opinion. The reports they wrote were usually in local languages and much of this material was never published in print but remained as project reports. It is the purpose of the present project to localize these report and to summarize and interpret their contents, and to give bibliographical information about where the sources can be located. Different experiences and conditions in the three countries account for somewhat different approaches of the three country chapters. There is no doubt that Chernobyl was a very significant social and psychological event in the three countries discussed in the present report. It was also regarded by many as a significant threat to public health, although radiation experts assured the public that the direct effects

  19. Brainstorming Versus Arguments Structuring in Online Forums

    Full Text Available We characterize electronic discussion forums as being of one of the following two types: Brainstorming Forums and Arguments Structuring Forums. In this work we analyze and classify the types of threading models occurring as a function of the type of forum. For our analysis we study forums attached to the 25 news sources most used by the aggregator Google News, as detected by a 2007 study. Most discussion forums associated with articles on these news sources seem to be designed not with the purpose of structuring arguments but mainly with the purpose of helping readers brainstorm easily their reactions to the corresponding news item. The forums were classified as to what user-supported metadata they gather and use in comment presentation. We compare the features observed for brainstorming forums, as learned via the aforementioned procedure, with the fea-tures of dedicated argument structuring forums. The argument structuring forums that were used as basis of the comparison are: YourView, DebateDecide, and Opinion Space. We notice significant differences in the obtained models for the two types of forums, as well as significant differences with respect to the the structuring of user submitted data in polls associated with major news channels. We believe that this is the first kind of work that deals with the issue above.

    In keeping with a mandate from the US Congress to provide opportunities for consumer education and information and to seek consumer input on national issues, the Department of Energy's Office of Consumer Affairs held a three-hour educational forum on the proposed nuclear waste disposal legislation. Nearly one hundred representatives of consumer, public interest, civic and environmental organizations were invited to attend. Consumer affairs professionals of utility companies across the country were also invited to attend the forum. The following six papers were presented: historical perspectives; status of legislation (Senate); status of legislation (House of Representatives); impact on the legislation on electric utilities; impact of the legislation on consumers; implementing the legislation. All six papers have been abstracted and indexed for the Energy Data Base.

    A network for material issues for Generation IV nuclear power has been initiated within the Nordic countries. The objectives of the Generation IV Nordic Nuclear Materials Forum (NOMAGE4) are to put the basis of a sustainable forum for Gen IV issues, especially focussing on fuels, cladding, structural materials and coolant interaction. Other issues include reactor physics, dynamics and diagnostics, core and fuel design. The present report summarizes the work performed during the year 2009. The efforts made include identification of organisations involved in Gen IV issues in the Nordic countries, update of the forum website, http://www.studsvik.se/GenerationIV, and investigation of capabilities for research within the area of Gen IV. Within the NOMAGE4 project a seminar on Generation IV Nuclear Energy Systems has been organized during 15-16th of October 2009. The aim of the seminar was to provide a forum for exchange of information, discussion on future research needs and networking of experts on Generation IV reactor concepts. As an outcome of the NOMAGE4, a few collaboration project proposals have been prepared/planned in 2009. The network was welcomed by the European Commission and was mentioned as an exemplary network with representatives from industries, universities, power companies and research institutes. NOMAGE4 has been invited to participate to the 'European Energy Research Alliance, EERA, workshop for nuclear structural materials' http://www.eera-set.eu/index.php?index=41 as external observers. Future plans include a new Nordic application for continuation of NOMAGE4 network. (author)

    - Goals: The main objectives of the health programme are collection and validation of existing data on cancer and non cancer diseases in the most highly contaminated regions of Ukraine, Russia and Belarus, common scientific expertise on main health indicators and reliable dosimetry, and finally communication of the results to the scientific community and to the public. - General Tasks: 1- Comparison between high and low exposed regions, 2- Description of trends over time, 3- Consideration of specific age groups. This methodological approach is applied on Solid cancer incidence and leukaemia incidence in different regions in Ukraine, Belarus and Russia, With a special focus on thyroid cancer in young exposed ages. - Thyroid cancer: Those exposed in very young ages continue to express a relatively high excess of thyroid cancer even though they have now reached the age group 15-29. Those exposed as young adults show a small increase, at least partly due to better screening conditions - Leukemia: Description of leukemia trends for various age groups show no clear difference between exposed and unexposed regions when focusing on those exposed at very young ages. The rates of childhood leukemia before and after the accident show no evidence of any increase (oblasts in Belarus over 1982-1998). - Specific studies: Incidence of congenital malformations in Belarus; Infant mortality and morbidity in the most highly contaminated regions; Potential effects of prenatal irradiation on the brain as a result of the Chernobyl accident; Nutritional status of population living in regions with different levels of contamination; Dosimetry of Chernobyl clean-up workers; Radiological passports in contaminated settlements. - Congenital malformations: As a national register was existing since the 1980's and gives the possibility to compare trends before and after the accident, results of congenital malformations describe large results collected over Belarus, There is no evidence of a

    2001-04-01

    Fifteen years after two massive explosions and a subsequent fire released a giant radioactive cloud into the atmosphere over the Chernobyl nuclear power plant located in what used to be the USSR, 388 farms with 230,000 sheep in Wales, England and Scotland are still subject to restriction orders. The contamination levels stand at several hundred Becquerels of cesium per kilogram of meat, too much to be consumed by human beings. The sheep have to be moved for some time to low or non-contaminated pastures in order to allow the bodies to loose some of their radioactivity before they can be slaughtered. For many countries the 1986 Chernobyl catastrophe came a public turning point for the future of nuclear energy. (author)

    Because of its public health, ecological and industrial consequences, the Chernobyl accident has become a myth which serves as the focus of many fears, justified or not. no one can question the seriousness of the event, but after fifteen years there is still no agreement about the effect it has had or will have on public health. For example, the total number of deaths attributed to Chernobyl varies from less than a hundred to several millions and congenital malformations from negligible to cataclysmic. Effects on public health may be calculated from data on contamination, from the dose received and from the risk, all three of which are likely to be very roughly known; or they may be evaluated on the spot, either by epidemiological studies or by examining medical registers. This report makes an inventory of the different risks and takes stock on them. (N.C.)

    Following the nuclear accidents in Chernobyl and later in Fukushima, the nuclear community has been faced with important issues concerning how to search for and diagnose biological consequences of low-dose internal radiation contamination. Although after the Chernobyl accident an increase in childhood papillary thyroid cancer (PTC) was observed, it is still not clear whether the molecular biology of PTCs associated with low-dose radiation exposure differs from that of sporadic PTC. We investigated tissue samples from 65 children/young adults with PTC using DNA microarray (Affymetrix, Human Genome U133 2.0 Plus) with the aim of identifying molecular differences between radiation-induced (exposed to Chernobyl radiation, ECR) and sporadic PTC. All participants were resident in the same region so that confounding factors related to genetics or environment were minimized. There were small but significant differences in the gene expression profiles between ECR and non-ECR PTC (global test, p < 0.01), with 300 differently expressed probe sets (p < 0.001) corresponding to 239 genes. Multifactorial analysis of variance showed that besides radiation exposure history, the BRAF mutation exhibited independent effects on the PTC expression profile; the histological subset and patient age at diagnosis had negligible effects. Ten genes (PPME1, HDAC11, SOCS7, CIC, THRA, ERBB2, PPP1R9A, HDGF, RAD51AP1, and CDK1) from the 19 investigated with quantitative RT-PCR were confirmed as being associated with radiation exposure in an independent, validation set of samples. Significant, but subtle, differences in gene expression in the post-Chernobyl PTC are associated with previous low-dose radiation exposure. (orig.)

    Despite the tragic accidents in Fukushima and Chernobyl, the nuclear power industry will continue to contribute to the production of electric energy worldwide until there are efficient and sustainable alternative sources of energy. The Chernobyl nuclear accident, which occurred 26 years ago in the former Soviet Union, released an immense amount of radioactivity over vast territories of Belarus, Ukraine, and the Russian Federation, extending into northern Europe, and became the most severe accident in the history of the nuclear industry. This disaster was a result of numerous factors including inadequate nuclear power plant design, human errors, and violation of safety measures. The lessons learned from nuclear accidents will continue to strengthen the safety design of new reactor installations, but with more than 400 active nuclear power stations worldwide and 104 reactors in the Unites States, it is essential to reassess fundamental issues related to the Chernobyl experience as it continues to evolve. This article summarizes early and late events of the incident, the impact on thyroid health, and attempts to reduce agricultural radioactive contamination.

    The implementation of laser vibrometers into various branches of industry solves complex technical problems as well as raising the authority of laser vibrometry as unique measurement tool. From this point of view, the nuclear industry is an interesting and attractive application field with specific and rigorous exploitation conditions of measuring systems. The objective of this work was to evaluate all advantages and disadvantages of the laser Doppler vibrometry with respect to nuclear power plant (NPP) equipment examination. The Chernobyl NPP is the ideal place for these purposes. The diagnostic ability on different Chernobyl NPP systems (e.g. third power unit main circulators, bearing shaft of fifth turbo-generator and various pipelines) has been demonstrated using laser Doppler vibrometers. The measurements performed by laser vibrometers were checked by standard Chernobyl NPP vibration measurement tools. The laser Doppler vibrometers (CLV, Polytec GmbH and LDV, Kiev University) have been tested and have shown full functionality in NPP zone at 0.5 sievert/hour radiation levels, high electromagnetic fields (magnetic component up to 5 kA/m) and significant vibrations.

These were (1) the first practical analog computer?"' with the capability to solve nonlinear differential equations and (2) the strobe light,5-7 which gives ample light to record rapidly moving mechanical motions. These two devices were used together as a system to study the transient performance of synchronous machines for my graduate studies. I must say that they did it well for many years.

    Full Text Available The user generated content on the web grows rapidly in this emergent information age. The evolutionary changes in technology make use of such information to capture only the user’s essence and finally the useful information are exposed to information seekers. Most of the existing research on text information processing, focuses in the factual domain rather than the opinion domain. Text mining plays a vital role in online forum opinion mining. But opinion mining from online forum is much more difficult than pure text process due to their semi structured characteristics. In this paper we detect online hotspot forums by computing sentiment analysis for text data available in each forum. This approach analyzes the forum text data and computes value for each piece of text. The proposed approach combines K-means clustering and Support Vector Machine (SVM classification algorithm that can be used to group the forums into two clusters forming hotspot forums and non-hotspot forums within the current time span. The experiment helps to identify that K-means and SVM together achieve highly consistent results. The prediction result of SVM is also compared with other classifiers such as Naïve Bayes, Decision tree and among them SVM performs the best.

  5. Comparison of the Chernobyl and Fukushima nuclear accidents: A review of the environmental impacts

    The environmental impacts of the nuclear accidents of Chernobyl and Fukushima are compared. In almost every respect, the consequences of the Chernobyl accident clearly exceeded those of the Fukushima accident. In both accidents, most of the radioactivity released was due to volatile radionuclides (noble gases, iodine, cesium, tellurium). However, the amount of refractory elements (including actinides) emitted in the course of the Chernobyl accident was approximately four orders of magnitude higher than during the Fukushima accident. For Chernobyl, a total release of 5300 PBq (excluding noble gases) has been established as the most cited source term. For Fukushima, we estimated a total source term of 520 (340–800) PBq. In the course of the Fukushima accident, the majority of the radionuclides (more than 80%) was transported offshore and deposited in the Pacific Ocean. Monitoring campaigns after both accidents reveal that the environmental impact of the Chernobyl accident was much greater than of the Fukushima accident. Both the highly contaminated areas and the evacuated areas are smaller around Fukushima and the projected health effects in Japan are significantly lower than after the Chernobyl accident. This is mainly due to the fact that food safety campaigns and evacuations worked quickly and efficiently after the Fukushima accident. In contrast to Chernobyl, no fatalities due to acute radiation effects occurred in Fukushima. - Highlights: • The environmental effects of Chernobyl and Fukushima are compared. • Releases of radionuclides from Chernobyl exceeded Fukushima by an order of magnitude. • Chernobyl caused more severe radiation-related health effects. • Overall, Chernobyl was a much more severe nuclear accident than Fukushima. • Psychological effects are neglected but important consequences of nuclear accidents.

    Accumulation of radionuclides by the higher fungi (macromycetes) after the accident on the Chernobyl atomic power plant in 1986 has been studied. Researches were spent in territory of the Chernobyl alienation zone and the Kiev region. Our research has shown that macromycetes accumulate almost all types of radionuclides originating from the accident ({sup 131}I, {sup 140}Ba /{sup 140}La, {sup 103}Ru, {sup 106}Ru, {sup 141}Ce, {sup 144}Ce, {sup 95}Nb, {sup 95}Zr, {sup 137}Cs and {sup 134}Cs). They accumulate the long-living {sup 90}Sr in much smaller (to 3 - 4 orders) quantities than {sup 137}Cs. We have established existence of two stages in accumulation of {sup 137}Cs by higher fungi after the accident on the Chernobyl NPP: the first stage resides in the growth of the concentration, the second - in gradual decrease of levels of specific activity of this radionuclide. Despite reduction of {sup 137}Cs specific activity level, the content of this radionuclide at testing areas of the 5-km zone around the Chernobyl NPP reaches 1,100,000 Bq/kg of fresh weight in 2013. We investigated dynamics of accumulation of Cs-137 in higher fungi of different ecological groups. One of the major factors that influence levels of accumulation of {sup 137}Cs by fungi is their nutritional type (ecological group). Fungi that belong to ecological groups of saprotrophes and xylotrophes accumulate this radionuclide in much smaller quantities than symbio-trophic fungi. As a result of the conducted research it has been established that symbio-trophic fungi store more {sup 137}Cs than any other biological objects in forest ecosystems. Among the symbio-trophic fungi species, species showing the highest level of {sup 137}Cs contamination vary in different periods of time after the deposition. It is connected with variability of quantities of these radio nuclides accessible for absorption at the depth of localization of the main part of mycelium of each species in a soil profile.

    In 1986 a reactor at the Chernobyl Nuclear Plant suffered a large explosion. The result had wide-ranging impacts. 31 severely exposed emergency workers died from acute radiation syndrome and 19 more later died from different causes. The perhaps controversial prediction by some authors is that around 4,000 will eventually die as a result of the increased cancer risk. A 19-mile restriction zone exists around the former reactor, but during the past 25 years radiation levels have fallen and it is now possible to take part in conducted tours of the deserted city of Pripyat, and the Chernobyl reactor site. Soil levels, however, remain highly radioactive, particularly in the restricted area. Kingston University holds:- • Soil profile sets from 3 locations in Belarus, with repeats at same location 1996 and 2000. • Lake sediment core samples. • Soil profiles at forestry sites. • Surface samples in a region suspected to have actinide content at 200km from Chernobyl. In addition to the above the impact of naturally occurring radon on human health around Chernobyl should not be ignored. About 23 per cent of homes in Ukraine are estimated to have radon levels above 100 Bq m-3, whilst concentrations of 10,000 Bq m-3 or more are known to exist in public water supplies. Some researchers have also suggested that mean annual doses of irradiation of the population caused by radon and it's progeny in air in buildings exceeds the doses received now by inhabitants of settlements located in the territories polluted by Chernobyl-derived nuclides in the Mogilev and Gomel regions in Belarus. This project incorporates a temporal comparison of transport results in undisturbed soils variously over a number of years, demonstrating relative measurements using both the original and new samples. This project will also focus on lake sediments from Southern Belarus and is a 'work in progress'. However, what we can say at this stage is that it is notable that the long lived isotopes of Cs-137

  8. The Energy Forum of Sri Lanka: Working toward appropriate expertise

    Science.gov (United States)

    Nieusma, Dean

    Taking my cue from the knowledge base and practices comprising appropriate technology development, and building on politics of expertise scholarship, this dissertation develops the concept of appropriate expertise: the combination of social and technical competences required to address marginalization through technological interventions. The dissertation asks what appropriate expertise looks like "on the ground" in the context of development as practiced by an exceptional group of technology designers from the Energy Forum of Sri Lanka: What design goals did they strive toward? What challenges did they face? What strategies did they employ? In an effort to answer these questions, the dissertation looks at how these designers interacted across a range of contexts with a broad spectrum of people and institutions, each with its own expertise to draw upon. In particular, it looks at how they situated their work in a highly contoured field of social power, where different types of expertise were used as resources for reinforcing or resisting existing power relations. I use the concept relations of expertise to denote the structure of expert interactions across multiple contexts of activity. Although this concept links to broad political-economic conditions that order varied expert practices, my analytic focus is at a different level: the situated experiences of expert practitioners. By starting with ground-level practices and understandings, I argue that creating new relations of expertise---that is, changing the nature of the interactions among experts and between experts and those they work with---is the key way my informants worked to legitimate marginalized perspectives and thereby empower marginalized social groups around technology-development practices. Appropriate expertise enables the creation of appropriate technologies, but it does more. It enables the creation of new relations of expertise, both through inspiring new forms of interpersonal interaction

  9. Making Sense of Chernobyl Nine Years After: TV News Reception Study of the Environmental Disaster

    Energy Technology Data Exchange (ETDEWEB)

    Vettenranta, Soilikki

    1998-12-31

    This thesis begins by describing how high-technology risks like nuclear power plant explosions intrude into people`s everyday consciousness through television news. It problematises the failure of the traditional concepts in the social sciences to measure the consequences of sense making of nuclear risks and examines the distinction between the concepts of risk communication and crisis information. The Chernobyl disaster is presented and its consequences for media research discussed. Media coverage of disasters is examined in detail. The research paradigm is considered from the epistemological and ontological distinctions and qualitative methods versus quantitative ones are discussed. The interview methodology is discussed and profile descriptions given of the fifteen respondents. These includes lay people, authorities and experts, and representatives of the media. The data are examined from an ontological approach, using constructivism as the research framework. The ontological analysis is based on the application of Heidegger`s existentiales as a scientific instrument. The epistemological approach is discussed by proceeding from Heidegger to Habermas` theory of the communicative action. Finally, the thesis concludes with a discussion of the theoretical basis and methods used. 264 refs., 1 fig., 4 tabs.

    Return of experience on Chernobyl post-accident management: the PAREX study Belarus is the country the most affected by the Chernobyl fallouts and is among the most significant experiences in the nuclear post-accident field. Despite specificities inherent to the political and social situation in Belarus, the experience of post-accidental management in this country holds a wealth of lessons in the perspective of preparation to a post-accidental situation in the French and European context. Through the PAREX project (2005-2006), the French Nuclear Safety Authority analysed the return of experience of Chernobyl post-accident management from 1986 to 2005 in order to draw its lessons in the perspective of a preparation policy. The study was led by a group of experts and involved the participation of a pluralistic group of about thirty participants (public authorities, local governments, NGOs, experts, operators). PAREX highlighted the complexity of a situation of long-lasting radioactive contamination (diversity of stakeholders and of dimensions at stake: health, environment, economy, society...). Beyond traditional public crisis management tools and frameworks, post-accident strategies also involves in the longer term a territorial and social response, which relies on local capacities of initiative. Preparation to such process requires experimenting new modes of operation that allow a diversity of local actors to take part to the response to a situation of contamination and to the surveillance system, with the support of public authorities. The conclusions of PAREX include a set of recommendations in this perspective. (authors)

    2012-07-01

    The scope of the conference (Nasal and Buccal Drug Delivery Conference, Management Forum; Chairs Franz Merkus and Julie Suman) was to consider innovations in drug delivery via the nose and oral cavity, notably for the delivery of vaccines, antimalarials and rapidly acting sedatives. Presentations from experts from academia, government agencies and commercial organisations were made over the 2 days. The advantages of both routes were ease of application, patient acceptability and no requirement to produce sterile products. These routes worked best for drugs that are water soluble--but with some lipophilicity--only require low doses, are acceptable to the patient and have low irritancy (particulary for the nasal route). Challenges relate to the effectiveness of deposition from the delivery systems and the efficient clearance mechanisms. It was concluded that for many drugs, buccal and nasal delivery could become the route of choice for their application; vaccines, in particular, appear to show promise for nasal delivery.

    1991-01-01

    Rule-based expert systems may be structurally and functionally mapped onto a special class of neural networks called expert networks. This mapping lends itself to adaptation of connectionist learning strategies for the expert networks. A parsing algorithm to translate C Language Integrated Production System (CLIPS) rules into a network of interconnected assertion and operation nodes has been developed. The translation of CLIPS rules to an expert network and back again is illustrated. Measures of uncertainty similar to those rules in MYCIN-like systems are introduced into the CLIPS system and techniques for combining and hiring nodes in the network based on rule-firing with these certainty factors in the expert system are presented. Several learning algorithms are under study which automate the process of attaching certainty factors to rules.

    Childhood victims were investigated focussing on the psychosomatic disorders. The subjects were some of the 3834 children who evacuated from the Chernobyl zone to Kiev (evacuees) and 200 children who have been living in Kiev since prior to the accident (comparison group). A psychological test administered to 504 evacuees aged 12-14 years at the time of the accident and the comparison group indicated that the frequencies of neutroticism, high level of anxiety and conflicts were significantly higher in the evacuees than in the comparison group (p<0.001). Another psychological test administered at puberty to the 504 evacuees and 200 other evacuees exposed to the accident at 4-6 years of age indicated that the psycho-emotional portrait of evacuated teenagers significantly changed with time since the accident. The effects of the Chernobyl accident on the health of the vegetative dystonia observed in 1987-1990 and 1990-1995 were higher in the evacuees than in the comparison group, although they were not statistically significant. Furthermore, a significant (p<0.001) association of the vegetative dystonia with peptic and cardiovascular disorders was observed. The present study indicates that the vegetative dystonia is still highly prevalent among childhood victims and deems to support that the vegetative dystonia may be a precursor of several diseases such as cardiovascular and peptic disorders. It should be emphasized that a health promotion program to produce a change in psychological and social problems after the Chernobyl accident is necessary to decrease the health impact among Ukrainian people.

  1. After Chernobyl. Psychological factors affecting health after a nuclear disaster

    Havenaar, J.M.

    1996-04-23

    During his stay in Belarus, Ukraine and Russia the author learned much about the medical and psychological consequences of the Chernobyl accident, and about the rapidly changing societies of the former Soviet Union. The chapters of this dissertation may be regarded as being stations along the way in this learning process. Chapter 1 describes his first impressions and the accounts he heard about the events that followed the catastrophe. It summarizes the current knowledge about the radiological consequences of the disaster. Chapter 2 presents a review of the literature about the psychological impact of disasters, such as Chernobyl, Bhopal and Three Mile Island, events that are characterized by the release of potentially harmful quantities of toxic substances into the environment. Chapters 3 and 4 describe the painstaking process of obtaining the necessary reliable research instruments, which were totally lacking in the Russian language. Without such instruments no valid epidemiological research is possible. Furthermore, these research instruments were to provide a tool to assist the Byelorussian physicians in their daily practice, helping them to assess the presence of psychosocial and psychiatric problems in their patients in a more reliable fashion. Chapter 5 describes the mental health situation in the region and analyses the presence of high-risk groups towards whom special intervention programmes. Chapter 6 investigates the question to what extent the high levels of psychopathology in Gomel can be attributed to the impact of the Chernobyl disaster, even more than six years after the event. In chapter 7 the perspective is widened. The field of mental health is left behind and the domain of public health is addressed. This chapter describes the relationship between subjective health and illness behaviour in relation to objective clinical parameters of physical and mental health. Finally, in chapter 8, the findings from these studies are critically reviewed and

Cohort of acute radiation syndrome (ARS survivors under medical observation at the S.I. "Research Center for Radiation Medicine of the National Academy of Medical Sciences of Ukraine" is the largest. Within the 25 years the functional state of the major organs and body systems, and metabolic homeostasis for this category of persons were studied, a comprehensive assessment of their health, mental and physical performance were given, and risk factors and peculiarities of stochastic and non-stochastic pathology courses were identified, as well as a system of rehabilitation patients after ARS was developed. ARS survivors are suffering from chronic diseases of internal organs and systems (from 5-7 to 10-12 diagnoses at the same time. A correlation between acute radiation effects and specific HLA phenotypes were revealed. The dynamics of the immune system recovery after irradiation was studied. The role and prognostic value of telomere length and programmed cell death of lymphocytes in the formation of the cellular effects of ionizing radiation were determined for the first time. Differences between spontaneous and radiation-induced acute myeloid leukemias were found. Dose-dependent neuropsychiatric, neurophysiological, neuropsychological and neuroimaging deviations were identified after irradiation at doses above 0.3 Sv. It was shown that the lymphocytes of Chernobyl clean-up workers with doses 350 – 690 mGy can induce "the bystander effect" in the non-irradiated cells even after 19 years after exposure. The rates of cancer incidence and mortality of victims, the lessons and key problems to be solved in the third decade after the Chernobyl accident are considered.

  7. Radiophobia: long-term psychological consequences of Chernobyl.

    Science.gov (United States)

    2002-02-01

    The primary health effect of Chernobyl has been widespread psychological distress in liquidators (workers brought in for cleanup), evacuees, residents of contaminated areas, and residents of adjacent noncontaminated areas. Several psychoneurological syndromes characterized by multiple unexplained physical symptoms including fatigue, sleep and mood disturbances, impaired memory and concentration, and muscle and/or joint pain have been reported in the Russian literature. These syndromes, which resemble chronic fatigue syndrome and fibromyalgia, are probably not due to direct effects of radiation because they do not appear to be dose related to radiation exposure and because they occur in areas of both high and low contamination.

    1991-01-01

    Concentrations of Chernobyl-derived radionuclides in airborne particulate matter over Washington D.C. have been determined by gamma-ray analysis of air filter samples collected during the months of May, June, and July 1986. The results indicate that long-lived nuclides were present in levels comparable to those measured previously at other eastern locations. Extensive washout of radioactivity occurred apparently as a result of heavy rainfall on May 20, and was followed by the arrival of airborne debris with elevated {sup 103}Ru/{sup 137}Cs and {sup 106}Ru/{sup 137}Cs activity ratios.

    On 29 April 1986, the Geological Survey of Finland (GSF) survey aircraft with a gamma ray spectrometer flew through a radioactive plume from the Chernobyl nuclear accident. The aircraft became contaminated and the gamma spectrometer measured radioactivity in the plume as well as radioactivity...... on the aircraft. By using simple assumptions on the build-up of contamination it has been possible to separate the signals from contamination and from plume. The analysis further showed that even a detector/spectrometer with low energy resolution is able to identify a contamination with iodine....

    Full text of publication follows: Italy entered with enthusiasm into the production of nuclear energy for civil use at the end of 50. By 1966 - with an overall output of 3.9 billions kWh - Italy had become the fourth world producer of electricity generated by nuclear reactions, the second one in Europe after Great Britain. Chernobyl's 1986 disaster, which so much shook public opinion all over Europe, had particularly important economic and political consequences in Italy. In a controversial referendum, held in November 1987, Italian citizens voted for the repeal of three laws which promoted the installation of nuclear power plants on the Italian soil and the participation of ENEL (National Institution for the Electrical Energy) to plant constructions abroad. The 1987 referendum was interpreted by the Italian government as an opposition to nuclear power generation - the following year, the four Italian plants (Garigliano, Latina, Trino Vercellese, Caorso) ceased their activity and plans to build new plants were abandoned. This decision marked the ruin of Italian research on nuclear energy, that in the 30 had known a glorious era thanks to Enrico Fermi works. As the 20. Anniversary of Chernobyl's accident is drawing near, the University of Milan and ICS-research group (Innovations in Communication of Science) at SISSA, Trieste, have decided to analyse jointly the reasons which brought Italy to give up its nuclear energy production. In the present scenario of controversies concerning the development of science and technology, in which European countries exchange experiences of best practice to involve the public in decision making processes, Italy reaction to Chernobyl accident can indeed be considered paradigmatic in that it anticipated crucial risks governance issues in today relationship between science and society. The research project draws on methodologies used in media studies and on socio linguistic analysis, as developed by risk perception and risk

    The environmental impacts of the nuclear accidents of Chernobyl and Fukushima are compared. In almost every respect, the consequences of the Chernobyl accident clearly exceeded those of the Fukushima accident. In both accidents, most of the radioactivity released was due to volatile radionuclides (noble gases, iodine, cesium, tellurium). However, the amount of refractory elements (including actinides) emitted in the course of the Chernobyl accident was approximately four orders of magnitude higher than during the Fukushima accident. For Chernobyl, a total release of 5,300 PBq (excluding noble gases) has been established as the most cited source term. For Fukushima, we estimated a total source term of 520 (340-800) PBq. In the course of the Fukushima accident, the majority of the radionuclides (more than 80%) was transported offshore and deposited in the Pacific Ocean. Monitoring campaigns after both accidents reveal that the environmental impact of the Chernobyl accident was much greater than of the Fukushima accident. Both the highly contaminated areas and the evacuated areas are smaller around Fukushima and the projected health effects in Japan are significantly lower than after the Chernobyl accident. This is mainly due to the fact that food safety campaigns and evacuations worked quickly and efficiently after the Fukushima accident. In contrast to Chernobyl, no fatalities due to acute radiation effects occurred in Fukushima.

    Following a succession of technical malfunctions and human errors, reactor No.4 of Chernobyl nuclear power plant explodes on April 26, 1986. Radioactive dust, aerosols, and gases (including iodine and caesium) are ejected into the atmosphere. The regions worst hit are in the immediate vicinity of the plant (Belarus, Ukraine) but deposits are very uneven, producing a 'leopard spot' type of pattern (Russian Federation). In Europe, propelled by easterly winds, the radioactive cloud disperses increasingly, scattering deposits over the whole Europe. At the beginning of May, the cloud arrives over France. The eastern portion of the country is most strongly affected. For the contamination, ground, water, and agriculture are contaminated by caesium deposits in Belarus, Ukraine and Russian Federation. In France, ground contamination is slight, fourteen years later, however, it is still detectable. It is hard to assess the impact on health in the vicinity of the Chernobyl plant; among children in southern Belarus, the number of thyroid cancers has risen one hundred-fold. The doses delivered in France represent generally less than 1% of the average annual dose from radioactivity of natural origin. But some of the doses received were higher. Today, the protective sarcophagus covering the damaged reactor is fragile. Reactor No.3, still in operation, continues to pose a risk but the shutdown is provide for december 2000. (N.C.)

    An assessment of the distribution of Chernobyl fallout in a Swedish forest was carried out and showed more than 95% of the {sup 137}Cs in the system to be of Chernobyl origin. The data show that approximately 87% of total fallout is found in soils, 6% in the bryophyte layer and 7% in standing biomass of trees. The mean deposition of {sup 137}Cs in the system (including soils, bryophytes, understorey vegetation, fungi, trees, moose and roe deer) was 54 kBq m{sup -2}. Fungi, understorey vegetation and ruminant populations collectively contained approximately 1% of total radiocaesium in the system. However, actual concentrations in these sample types were higher than in any other category, mostly exceeding the limit of 1500 Bq kg{sup -1} for consumption of wild produce in Sweden. These categories represent the principal foodstuffs responsible for radiation transfer to man from the system and though negligible in total biomass there is potential for significant dose transfer to individuals who are regular consumers of wild forest produce.

    Radioactivity released from disasters like Chernobyl and Fukushima is a global hazard and a threat to exposed biota. To minimize the deleterious effects of stressors organisms adopt various strategies. Plants, for example, may delay germination or stay dormant during stressful periods. However, an intense stress may halt germination or heavily affect various developmental stages and select for life history changes. Here, we test for the consequence of exposure to ionizing radiation on plant development. We conducted a common garden experiment in an uncontaminated greenhouse using 660 seeds originating from 33 wild carrots (Daucus carota) collected near the Chernobyl nuclear power plant. These maternal plants had been exposed to radiation levels that varied by three orders of magnitude. We found strong negative effects of elevated radiation on the timing and rates of seed germination. In addition, later stages of development and the timing of emergence of consecutive leaves were delayed by exposure to radiation. We hypothesize that low quality of resources stored in seeds, damaged DNA, or both, delayed development and halted germination of seeds from plants exposed to elevated levels of ionizing radiation. We propose that high levels of spatial heterogeneity in background radiation may hamper adaptive life history responses.

  7. Consequences of the Chernobyl accident for reindeer husbandry in Sweden

    1990-09-01

    Full Text Available Large parts of the reindeer hearding area in Sweden were contaminated with radioactive caesium from the Chernobyl fallout. During the first year after the accident no food with activity concentrations exceeding 300 Bq/kg was allowed to be sold in Sweden. This meant that about 75% of all reindeer meat produced in Sweden during the autumn and winter 1986/87 were rejected because of too high caesium activités. In May 1987 the maximum level for Cs-137 in reindeer, game and fresh-water fish was raised to 1500 Bq/kg. During the last two year, 1987/88 and 1988/89, about 25% of the slaughtered reindeer has had activities exceeding this limit. The effective long-time halflife or radiocaesium in reindeer after the nuclear weapon tests in the sixties was about 7 years. If this halflife is correct also for the Chernobyl fallout it will take about 35 years before most of the reinder in Sweden are below the current limit 1500 Bq/kg in the winter. However, by feeding the animals uncontaminated food for about two months, many reindeer can be saved for human consumption.

  8. The Chernobyl experience in the area of retrospective dosimetry.

    The Chernobyl accident, which occurred on 26 April 1986 at a nuclear power plant located less than 150 km north of Kiev, was the largest nuclear accident to date. The unprecedented scale of the accident was determined not only by the amount of released activity, but also by the number of workers and of the general public involved, and therefore exposed to increased doses of ionising radiation. Due to the unexpected and large scale of the accident, dosimetry techniques and practices were far from the optimum; personal dosimetry of cleanup workers (liquidators) was not complete, and there were no direct measurements of the exposures of members of the public. As a result, an acute need for retrospective dose assessment was dictated by radiation protection and research considerations. In response, substantial efforts have been made to reconstruct doses for the main exposed cohorts, using a broad variety of newly developed methods: analytical, biological and physical (electron paramagnetic resonance spectroscopy of teeth, thermoluminescence of quartz) and modelling. This paper reviews the extensive experience gained by the National Research Center for Radiation Medicine, Academy of Medical Sciences, Ukraine in the field of retrospective dosimetry of large cohorts of exposed population and professionals. These dose reconstruction projects were implemented, in particular, in the framework of epidemiological studies, designed to follow-up the medical consequences of the Chernobyl accident and study health effects of ionizing radiation, particularly Ukrainian-American studies of cataracts and leukaemia among liquidators.

    The FORUM is an ACR planning activity focused on a specific topic deemed to be of long-range importance to the college. A select panel of multidisciplinary experts met in 2004 to consider the ramifications of imaging screening from diverse perspectives. Considerations included the nature of screening for disease, its technological issues, and biases associated with the perceived success of screening; potential technologies and target diseases; business and economics; insurance coverage; ethics and the law; how imaging screening could be paired with nonimaging screening; and how the lay public perceives screening. The FORUM participants considered how imaging screening might develop over the next 5 to 10 years and made recommendations to the ACR on actions it might take to benefit both the specialty and patients.

    A mass of traces of human activities show rich dynamic patterns. In this article, we comprehensively investigate the dynamic patterns of 50 thousands of researchers' activities in Sciencenet, the largest multi-disciplinary academic community in China. Through statistical analyses, we found that (i) there exists a power-law scaling between the frequency of visits to an academic forum and the number of corresponding visitors, with the exponent being about 1.33; (ii) the expansion process of academic forums obeys the Heaps' law, namely the number of distinct visited forums to the number of visits grows in a power-law form with exponent being about 0.54; (iii) the probability distributions of time intervals and the number of visits taken to revisit the same academic forum both follow power-laws, indicating the existence of memory effect in academic forum activities. On the basis of these empirical results, we propose a dynamic model that incorporates the exploration, preferential return with memory effect, which can well reproduce the observed scaling laws.

    2015-12-01

    In this report, we have reviewed the basic features of the accident processes and radioactivity releases that occurred in the Chernobyl accident (1986) and in the Fukushima-1 accident (2011). The Chernobyl accident was a power-surge accident that was caused by a failure of control of a fission chain reaction, which instantaneously destroyed the reactor and building, whereas the Fukushima-1 accident was a loss-of-coolant accident in which the reactor cores of three units were melted by decay heat after losing the electricity supply. Although the quantity of radioactive noble gases released from Fukushima-1 exceeded the amount released from Chernobyl, the size of land area severely contaminated by (137)Cesium ((137)Cs) was 10 times smaller around Fukushima-1 compared with around Chernobyl. The differences in the accident process are reflected in the composition of the discharged radioactivity as well as in the composition of the ground contamination. Volatile radionuclides (such as (132)Te-(132)I, (131)I, (134)Cs and (137)Cs) contributed to the gamma-ray exposure from the ground contamination around Fukishima-1, whereas a greater variety of radionuclides contributed significantly around Chernobyl. When radioactivity deposition occurred, the radiation exposure rate near Chernobyl is estimated to have been 770 μGy h(-1) per initial (137)Cs deposition of 1000 kBq m(-2), whereas it was 100 μGy h(-1) around Fukushima-1. Estimates of the cumulative exposure for 30 years are 970 and 570 mGy per initial deposition of 1000 kBq m(-2) for Chernobyl and Fukusima-1, respectively. Of these exposures, 49 and 98% were contributed by radiocesiums ((134)Cs + (137)Cs) around Chernobyl and Fukushima-1, respectively.

    The radiation dose on tooth enamel of children living close to Chernobyl has been evaluated by EPR. The sample preparation was reduced to a minimum of mechanical steps to remove a piece of enamel. A standard X-ray tube at low energy was used for additive irradiation. The filtration effect of facial soft tissue was taken into account. The radiation dose for a group of teeth slightly exceeds the annual dose, whereas for another group the dose very much exceeds the annual dose. Since the higher dose is found in teeth whose enamel have much lower EPR sensitivity to the radiation, it can be suggested that for these teeth the native signal could alter the evaluation of the smaller radiation signal.

Radioactive debris in which {sup 106}Ru, {sup 125}Sb, and {sup 134}Cs were enriched relative to {sup 137}Cs reached the west coast of the United States during the first week of May 1986. The air mass that carried this debris seems to have circled the world and reached the west coast for the second time 3 weeks later during the last week of May 1986. Results obtained in this study indicate that the initial release of nuclear debris from the Chernobyl reactor took place in a manner similar to the atmospheric injection of radionuclides from a nuclear weapon's test.

When 80% of graduating physicists will not be employed in academic positions, and 50% of all jobs for these physicists will be industrial sector, the importance of bringing our next generation of scientists up to speed on industrial applications is becoming much more important with the rapid, world-wide development of technology. FIAP is initiating a forum on entrepreneurship as a major role for the next generation of scientists. As physicists are problem solvers and the entrepreneurial experience is all about problem solving: whether involving technology, building a team, or financing a business. This forum seeks to link successful entrepreneurial physicists with the upcoming generation, through the dissemination of their global expertise and experience. The forum will consist of a panel discussion and then be open to question and answers from the audience.

    A network for materials issues has been initiated in 2009 within the Nordic countries. The original objectives of the Generation IV Nordic Nuclear Materials Forum (NOMAGE4) were to form the basis of a sustainable forum for Gen-IV issues, especially focusing on fuels, cladding, structural materials and coolant interaction. Over the last years, other issues such as reactor physics, thermal hydraulics, safety and waste have gained in importance (within the network) and therefore the scope of the forum has been enlarged and a more appropriate and more general name, NORDIC-GEN4, has been chosen for the forum. Further, the interaction with non-Nordic countries (such as The Netherlands (JRC, NRG) and Czech Republic (CVR)) will be increased. Within the NOMAGE4 project, a seminar was organized by IFE-Halden during 31 October - 1 November 2011. The seminar attracted 65 participants from 12 countries.

    1998-03-01

    The present paper is an analysis of the results of epidemiological studies in Belarus about the after-effects of the accident at the Chernobyl atomic power station (ChAPS), based on published data at scientific institutes, organs and institutions of Ministry of Health. In the last years the affected population showed thereby more significant - as compared with republican indices - growth of incidence in the majority of diseases (first of all: digestion, urogenital, nervous, endocrine systems, diseases of ear, throat, nose both among adults and among children). Aggravation of health state continues in the participants of liquidation of the ChAPS accident consequences and the evacuees from the alienation zone which have obtained considerable radiation load to organism (rise of incidence of diseases of endocrine, cardiovascular, nervous system etc.). Considerable growth of thyroid cancer incidence is registered in Belarus children and adolescents, especially in the Gomel and Brest regions. This is conditioned by dose commitments on thyroid gland due to iodine radionuclides in first period after the accident, incorrect iodine prophylaxy, and goitre endemic. The rise of hereditary pathology is registered too. An expressed increase of oncological diseases is observed therewith mainly in the Gomel region, especially in the districts with high level of radiocontamination and, consequently, significant radiation load. First of all, this relates to the growth of incidence of cancer of lungs, mammary gland, bladder. The analysis of epidemiological studies performed in Belarus after the ChAPS catastrophe and comparison of them with data obtained in the pre-Chernobyl period testify to the aggravation of health state of Belarus population. The specialists unambiguously recognize the direct influence of radioactive pollution in the environment on rise of thyroid pathologies, hereditary and congenial diseases, and cancers of different localizations. There is no unique opinion

  10. Estimated long term health effects of the Chernobyl accident

    Apart from the dramatic increase in thyroid cancer in those exposed as children, there is no evidence to date of a major public health impact as a result of radiation exposure due to the Chernobyl accident in the three most affected countries (Belarus, Russia, and Ukraine). Although some increases in the frequency of cancer in exposed populations have been reported ,these results are difficult to interpret, mainly because of differences in the intensity and method of follow-up between exposed populations and the general population with which they are compared. If the experience of the survivors of the atomic bombing of Japan and of other exposed populations is applicable, the major radiological impact of the accident will be cases of cancer. The total lifetime numbers of excess cancers will be greatest among the `liquidators` (emergency and recovery workers) and among the residents of `contaminated` territories, of the order of 2000 to 2500 among each group (the size of the exposed populations is 200,000 liquidators and 3,700,000 residents of `contaminated` areas). These increases would be difficult to detect epidemiologically against an expected background number of 41500 and 433000 cases of cancer respectively among the two groups. The exposures for populations due to the Chernobyl accident are different in type and pattern from those of the survivors of the atomic bombing of Japan. Thus predictions derived from studies of these populations are uncertain. The extent of the incidence of thyroid cancer was not envisaged. Since only ten years have lapsed since the accident, continued monitoring of the health of the population is essential to assess the public health impact.

    Gathering information, necessary forms, and financial calculations needed to generate a "capital investment proposal" is an extremely complex and difficult process. The intent of the capital investment proposal is to ensure management that the proposed investment has been thoroughly investigated and will have a positive impact on corporate goals. Meeting this requirement typically takes four or five experts a total of 12 hours to generate a "Capital Package." A Capital Expert System was therefore developed using "Personal Consultant." The completed system is hybrid and as such does not depend solely on rules but incorporates several different software packages that communicate through variables and functions passed from one to another. This paper describes the use of expert system techniques, methodology in building the knowledge base, contexts, LISP functions, data base, and special challenges that had to be overcome to create this system. The Capital Expert System is the successful result of a unique integration of artificial intelligence with business accounting, financial forms generation, and investment proposal expertise.

    Science.gov (United States)

    2013-01-01

    On the basis of the radionuclide specific activity measurements made on 832 samples of fish in 2009-2011 and taking into account literature data, the parameters of the stochastic model have been derived to describe the 137Cs and 90Sr contents in typical commercial fish species in the Kiev Reservoir at the late phase of the Chernobyl accident, including: statistical variability, seasonal changes and monotonous long-term trends. At any fixed moment of the year the standard deviations of logarithms of the 137Cs and 90Sr specific activities in carnivorous and benthophage fish species do not reliably differ, making up at average 0.4. The maximum vari- ation of the 137Cs specific activity (a four-fold decrease from April to November) was observed in pike. The obtained values of the ecological half-life periods for 137Cs and 90Sr (1.3-14 years) in fish of the Kiev reservoir in 2002-2012 were significantly lower than both the radioactive decay periods and the estimates of the IAEA Chernobyl Forum. Based on the obtained model parameters, the dynamics of the 137Cs and 90Sr specific ac- tivities in main commercial fish of the Kiev reservoir has been described and the risk of exceeding the permis- sible levels of these radionuclides in fish at the late phase of the Chernobyl accident has been estimated. Now the risk of catching fish with the specific activities of 137Cs and 90Sr above the permissible levels (150 Bq/kg and 35 Bq/kg, respectively) does not exceed 10% (except perch in the spring spawning period that is banned for fishing in Ukraine). Corresponding risks for roach, white bream and rudd are less than 0.1%.

    Along with rapidly expanding applications of life science and technology, technical experts have been implicated more and more often with ethical, social, and legal problems than before. It should be noted that in this background there are scientific and social uncertainty elements which are inevitable during the progress of life science in addition to the historically-established social unreliability to scientists and engineers. In order to solve these problems, therefore, we should establish the social governance with ‘relief’ and ‘reliance’ which enables for both citizens and engineers to share the awareness of the issues, to design social orders and criterions based on hypothetical sense of values for bioethics, to carry out practical use management of each subject carefully, and to improve the sense of values from hypothetical to universal. Concerning these measures, the technical experts can learn many things from the present performance in the medical field.

    The ALICE experiment at CERN employs a number of human operators (shifters), who have to make sure that the experiment is always in a state compatible with taking Physics data. Given the complexity of the system and the myriad of errors that can arise, this is not always a trivial task. The aim of this paper is to describe an expert system that is capable of assisting human shifters in the ALICE control room. The system diagnoses potential issues and attempts to make smart recommendations for troubleshooting. At its core, a Prolog engine infers whether a Physics or a technical run can be started based on the current state of the underlying sub-systems. A separate C++ component queries certain SMI objects and stores their state as facts in a Prolog knowledge base. By mining the data stored in dierent system logs, the expert system can also diagnose errors arising during a run. Currently the system is used by the on-call experts for faster response times, but we expect it to be adopted as a standard tool by reg...

    2007-11-01

    The ETHOS Project, supported by the radiation protection research program of the European Commission (EC), was implemented in the mid-1990's with the support of the Belarus authorities as a pilot project to initiate a new approach for the rehabilitation of living conditions in the contaminated territories of the Republic. This initiative followed a series of studies performed in the context of the EC Community of Independent States cooperation program to evaluate the consequences of the Chernobyl accident (1991-1995), which clearly brought to the fore that a salient characteristic of the situation in these territories was the progressive and general loss of control of the population on its daily life. Furthermore, due to the economic difficulties during the years following the breakdown of the USSR, the population was developing private production and, in the absence of know-how and adequate means to control the radiological quality of foodstuffs, the level of internal exposure was rising significantly. The aim of the project was primarily to involve directly the population wishing to stay in the territories in the day-to-day management of the radiological situation with the goal of improving their protection and their living conditions. It was based on clear ethical principles and implemented by an interdisciplinary team of European experts with specific skills in radiation protection, agronomy, social risk management, communication, and cooperation in complex situations, with the support of local authorities and professionals. In a first phase (1996-1999), the ETHOS Project was implemented in a village located in the Stolyn District in the southern part of Belarus. During this phase, a few tens of villagers were involved in a step-by-step evaluation of the local radiological situation to progressively regain control of their daily life. In a second phase (1999-2001), the ETHOS Project was extended to four other localities of the District with the objective to

Notably, it describes contamination mechanisms and how food, milk, vegetables, water organisms become hazardous. It highlights the influence of the initial contamination concentration. Then, it addresses soil contamination where caesium 137 reveals itself not much mobile and concentrated in surface layers. As far as oceans are concerned, they are said to be able to absorb radioactivity: 60 years of anthropic radioactive releases apparently did not have any obvious negative impact on sea environment. Underground waters are affected with some delay, and radioactive dusts which are present in the atmosphere fall with the rain and may appear again later in case of forest fires as it has been noticed. A brief article presents the French radioactivity detection network. The lack of knowledge on the effect of low doses is also commented. The technological aspect is addressed, with the development of automatic means of intervention.

It was demonstrated that significant reductions in the dose rate both indoor (DRF = 0.27) and outdoor (DRF = 0.17) can be achieved when a careful cleaning is undertaken. This report describes the decontamination work carried out and the results obtained. The roof of one of the houses was replaced with a new roof. This reduced the Chernobyl related dose rate by 10% at the ground floor and by 27% at the first floor. The soil around the houses was removed by a bobcat, while carefully monitoring the ground for residual contamination with handheld dose meters. By monitoring the decline in the dose rate during the different stages of the work the dose reducing effect of each action has been estimated. This report also describes a test of a skim-and-burial plough developed especially for treatment of contaminated land. In the appendices of the report the measurement data is available for further analysis. (au) 24 tabs., 75 ills., 33 refs.

  7. Radiocesium in lichens and reindeer after the Chernobyl accident

    1990-09-01

    Full Text Available After the Chernobyl accident the sampling and measuring program of the Finnish Centre for Radiation and Nuclear Safety was intensified both for surveillance and research purposes. The deposition pattern of radionuclides was more complicated than from the global fallout after the nuclear weapons tests. The radioactive deposition was very unevenly distributed in Lapland, as also in the rest of Finland. Fortunately, the amounts of deposition in Lapland were only about one-tenth of the corresponding amount of deposition in southern Finland. In 1986-87 the mean concentration of Cs-137 in lichens and in reindeer meat increased to about the same level as in 1972-73 or to about 30 per cent of the maximum levels found in 1964-65 after the nuclear weapons tests. The activity concentrations in reindeer tissues vary according to season. In winter, reindeer eat considerable amounts of lichens with high radiocesium concentrations. In summer, lichens are replaced by other forage such as leaves from trees, green plants, etc. The ratio of Cs-137 concentration in reindeer meat between summer and winter is about 0.2. The mean concentration of Cs-137 in meat for consumption from the slaughtering period 1986-87 was 720 Bq/kg fresh weight. After that time concentrations started decreasing since no new fallout was deposited.

    The International Program on the Health Effects of the Chernobyl Accident (IPHECA) was established by the World Health Organization (WHO) in 1991. Currently, the technical part of IPHECA consists of five projects addressing the following areas of priority health problems or needs: thyroid, hematology, brain damage in utero, epidemiological registry and oral health. Important findings are: 1) a significant increase of thyroid cancer in children in Belarus and Ukraine since 1989, and in Russia since 1992 though not so pronounced. A relationship between detected thyroid cancers and radiation exposure is yet to be established, 2) no increase yet in the incidence of hemoblastoses in the three States, 3) no relationship established between mental retardation and radiation exposure in utero in 4,500 children investigated. The importance of dosimetry and biological indicators of radiation damage has been recognized by IPHECA. Several methods of biological and physical dosimetry are being employed using instrumentation provided by IPHECA. Some preliminary results indicate: 1) unstable aberrations can indicate an integral exposure but it is heavily biased to recent exposures, 2) when comparing healthy persons and patients with hematological diseases in contaminated areas, there is a higher ratio of total aberrations compared to their background and that the level of stable is lower than unstable aberrations, and 3) by applying electron spin resonance (ESR) it has been shown that the individual distribution of doses approaches a log-normal one, especially for adults, and that a peak shift towards higher doses is noticeable for children.

    Full Text Available Plants have the ability to grow and successfully reproduce in radio-contaminated environments, which has been highlighted by nuclear accidents at Chernobyl (1986 and Fukushima (2011. The main aim of this article is to summarize the advances of the Chernobyl seed project which has the purpose to provide proteomic characterization of plants grown in the Chernobyl area. We present a summary of comparative proteomic studies on soybean and flax seeds harvested from radio-contaminated Chernobyl areas during two successive generations. Using experimental design developed for radio-contaminated areas, altered abundances of glycine betaine, seed storage proteins, and proteins associated with carbon assimilation into fatty acids were detected. Similar studies in Fukushima radio-contaminated areas might complement these data. The results from these Chernobyl experiments can be viewed in a user-friendly format at a dedicated web-based database freely available at www.chernobylproteomics.sav.sk.

    The mandate of the National Round Table on the Environment and the Economy (NRTEE) is to identify, explain and promote the principles and practices of sustainable development at the national level. In early 1998, NRTEE held a national forum on climate change at which the potential impacts of climate change on Canada were discussed and the most appropriate response for Canada was debated. Many scientists agree that the buildup of human-generated greenhouse gases in the atmosphere could have disastrous impacts on weather patterns, ecosystems and economic activity worldwide. At the Kyoto conference, all developed countries, including Canada, agreed to set targets to reduce greenhouse gas emissions. The NRTEE forum provided an opportunity to discuss the general approaches that Canada can take to deal with climate change and at what cost. The choices and trade-offs that Canadians will face were also discussed.

    The accident at the Chernobyl NPP (nuclear power plant) was the most serious ever to have occurred in the history of nuclear energy. The consumption of contaminated foodstuffs in affected areas was a significant source of irradiation for the population. A wide range of different countermeasures have been used to reduce exposure of people and to mitigate the consequences of the Chernobyl accident for agriculture in affected regions in Belarus, Russia and Ukraine. This paper for the first time summarises key data on countermeasure application over twenty years for all three countries and describes key lessons learnt from this experience. (review)

    The Belarusian government's decision of the last decade to build a nuclear power plant near the city of Ostrovets, in northern Belarus, has proven to be controversial, resulting in a great deal of debate about nuclear energy in the country. The debate was inevitably shaped by the traumatic event that affected Belarus - the Chernobyl nuclear accident of 1986. The Belarusian authorities have consistently promoted a positive view of nuclear energy to the population in order to overcome the so-called 'Chernobyl syndrome' and deliberately shaped nuclear risk communication. As a result, the issue of trust remains crucial in all nuclear debates in Belarus.

    Full Text Available Inks, drilling fluids, shower gels and drug delivery vehicles are just a few examples of the many industrial and consumer products based on colloidal and nanostructured complex fluids. The successful formulation of these materials is promoted by understanding how rheological behaviour, which typically dictates performance, relates to underlying microstructure. However, this knowledge can be difficult to obtain for those without the necessary expertise. This article shows how recent developments in rheometer technology address this issue. New rheometers, exemplified by the Kinexus from Malvern have expert knowledge embedded within the instrument and are able to guide users through measurement and data analysis to relevant information. Such systems facilitate development of the design rules to optimize formulations and generate novel and high performance materials of the future.

    Resuspension can be an important secondary source of contamination after a release has stopped, as well as a source of contamination for people and areas not exposed to the original release. The inhalation of resuspended radionuclides contributes to the overall dose received by exposed individuals. Based on measurements collected after the Chernobyl accident, Scenario R was developed to provide an opportunity to test existing mathematical models of contamination resuspension. In particular, this scenario provided the opportunity to examine data and test models for atmospheric resuspension of radionuclides at several different locations from the release, to investigate resuspension processes on both local and regional scales, and to investigate the importance of seasonal variations of these processes. Participants in the test exercise were provided with information for three different types of locations: (1) within the 30-km zone, where local resuspension processes are expected to dominate; (2) a large urban location (Kiev) 120 km from the release site, where vehicular traffic is expected to be the dominant mechanism for resuspension; and (3) an agricultural area 40-60 km from the release site, where highly contaminated upwind 'hot spots' are expected to be important. Input information included characteristics of the ground contamination around specific sites, climatological data for the sites, characteristics of the terrain and topography, and locations of the sampling sites. Participants were requested to predict the average (quarterly and yearly) concentrations of 137 Cs in air at specified locations due to resuspension of Chernobyl fallout; predictions for 90 Sr and 239 + 240 Pu were also requested for one location and time point. Predictions for specified resuspension factors and rates were also requested. Most participants used empirical models for the resuspension factor as a function of time K(t), as opposed to process-based models. While many of

    For April 25, 1986 the annual stop of the unit 4 of the nuclear power plant of Chernobyl was programmed, in order to carry out maintenance tasks. This unit was equipped with a reactor of 1000 MW, type RBMK, developed in the former Soviet Union, this type of reactors uses graphite like moderator, the core is refrigerated with common water in boil, and the fuel is uranium enriched to 2%. Also it had been programmed to carry out, before stopping the operation of the power station, a test with one of the two turbogenerators, which would not affect to the reactor. However, the intrinsic characteristics of the design of the reactor and the fact that the operators disconnected intentionally several systems of security that had stopped the reactor automatically, caused a decontrolled increase of the power (a factor 1000 in 4 seconds), with the consequent fusion of the fuel and the generation of a shock wave, produced by the fast evaporation of the refrigeration water and caused by the interaction of the fuel fused with the same one. It broke the core in pieces and destroy the structure of the reactor building that was not resistant to the pressure. When being exposed to the air, the graphite of the moderator entered in combustion, while the radioactive material was dispersed in the environment. The radionuclides liberation was prolong during 10 days, and only it was stopped by means of the one poured from helicopters, of some 5000 tons of absorbent materials on the destroyed reactor, as long as tunnels were dug to carry out the cooling of the core with liquid nitrogen. Later on, the whole building of the damaged reactor was contained inside a concrete building. The immediate consequence of the accident was the death of 31 people, between operators of the nuclear power station and firemen. One of people died as consequence of the explosion and 30 died by cause of the irradiation, with dose of the order of 16 Gy. The liberated radioactive material was the entirety of the

    Quality and Reliability are key requirements in the energy transmission industry. Tennessee Gas Co. a division of El Paso Energy, has applied Gensym`s G2, object-oriented Expert System programming language as a standard tool for maintaining and improving quality and reliability in pipeline operation. Tennessee created a small team of gas controllers and engineers to develop a Proactive Controller`s Assistant (ProCA) that provides recommendations for operating the pipeline more efficiently, reliably and safely. The controller`s pipeline operating knowledge is recreated in G2 in the form of Rules and Procedures in ProCA. Two G2 programmers supporting the Gas Control Room add information to the ProCA knowledge base daily. The result is a dynamic, constantly improving system that not only supports the pipeline controllers in their operations, but also the measurement and communications departments` requests for special studies. The Proactive Controller`s Assistant development focus is in the following areas: Alarm Management; Pipeline Efficiency; Reliability; Fuel Efficiency; and Controller Development.

    Full Text Available It was established in pot experiments that infection with powdery mildew (Erysiphe graminis DC. f. sp. tritici Em. Marchal and brown rust (Puccinia triticana Erikss. & Henn. of three wheat (Triticum aestivum L. cultivars ('Mironovskaya 808', 'Polesskay 70', and 'Kiyanka' grown from seeds, collected in the Chernobyl exclusion zone, was 1.5–2.0 times higher than that of plants grown from control seeds. On filed plots in the Chernobyl zone, wheat plant resistance to biotic stress was reduced. At artificial infection with brown rusts, the disease development was enhanced on plots with increased radiation background. One of the mechanisms of declined phytoimmunity potential under the action of low doses of chronic irradiation is evidently a reduced activity of plant proteinase inhibitors. Thus, in wheat and rye (Secale cereale L., cv. ‘Saratovskaya’ kernels, their activity reduced by 35–60% as compared to control. Active form and race formation in the population of the grass stem rust causal agent (Puccinia graminis Pers. was observed in the Chernobyl zone. A “new” population of this fungus with high frequency of more virulent clones than in other Ukraine regions was distinguished. The results obtained independently in greenhouse and field trials performed in the Chernobyl zone demonstrated radiation stress influence on the pathogen–plant system. They indicate a necessity of monitoring the microevolutionary processes occurring in both plants and their pathogens under conditions of technogenic stresses.

    Following the accident at the Chernobyl nuclear reactor power station in the USSR on April 26, 1986, the Environmental Measurements Laboratory (EML) initiated a number of research projects as follows: (1) selected sites in both the Deposition and Surface Air networks were alerted and their sampling protocols adjusted to accommodate the anticipated arrival times and activity concentrations of the Chernobyl debris; (2) a number of cooperative programs involving field work, sampling, analysis and data interpretation were set up with institutions and scientists in other countries; (3) EML's Regional Baseline Station at Chester, NJ, as well as the roof of the Laboratory in New York City, provided bases for sampling and measurements to study the radionuclide concentrations, radiation levels, physical characteristics and potential biological implications of the Chernobyl fallout on the northeastern United States; and (4) the resulting fallout from the Chernobyl accident provided an 'experiment of opportunity' in that it enabled us to study fresh fission product deposition using collection systems resurrected from the 1950's and 1960's for comparison with current state-of-the-art methodology. The 13 reports of this volume have been entered separately into the data base.

    The severe nuclear accident at Chernobyl in 1986 resulted in the worst reported accidental exposure of radioactive material to free-living organisms. Short-term effects on human populations inhabiting polluted areas include increased incidence of thyroid cancer, infant leukaemia, and congenital malformations in newborns. Two recent studies have reported, although with some controversy, that germline mutation rates were increased in humans and voles living close to Chernobyl, but little is known about the viability of the organisms affected. Here we report an increased frequency of partial albinism, a morphological aberration associated with a loss of fitness, among barn swallows, Hirundo rustica, breeding close to Chernobyl. Heretability estimates indicate that mutations causing albinism were at least partly of germline origin. Furthermore, evidence for an increased germline mutation rate was obtained from segregation analysis at two hypervariable microsatellite loci, indicating that mutation events in barn swallows from Chernobyl were two- to tenfold higher than in birds from control areas in Ukraine and Italy.

  5. RADIATION ECOLOGY ISSUES ASSOCIATED WITH MURINE RODENTS AND SHREWS IN THE CHERNOBYL EXCLUSION ZONE

    Energy Technology Data Exchange (ETDEWEB)

    Farfan, E.; Jannik, T.

    2011-10-01

    This article describes major studies performed by the Chernobyl Center's International Radioecology Laboratory (Slavutich, Ukraine) on radioecology of murine rodents and shrews inhabiting the Chernobyl Exclusion Zone. The article addresses the long-term (1986-2005) and seasonal dynamics of radioactive contamination of animals, and reviews interspecies differences in radionuclide accumulations and factors affecting the radionuclide accumulations. It is shown that bioavailability of radionuclides in the 'soil-to-plant' chain and a trophic specialization of animals play key roles in determining their actual contamination levels. The total absorbed dose rates in small mammals significantly reduced during the years following the Chernobyl Nuclear Power Plant accident. In 1986, the absorbed dose rate reached 1.3-6.0 Gy hr{sup -1} in the central areas of the Chernobyl Exclusion Zone (the 'Red Forest'). In 1988 and 1990, the total absorbed dose rates were 1.3 and 0.42 Gy hr{sup -1}, respectively. In 1995, 2000, and 2005, according to the present study, the total absorbed dose rates rarely exceeded 0.00023, 0.00018, and 0.00015 Gy hr{sup -1}, respectively. Contributions of individual radiation sources into the total absorbed dose are described.

  7. Has fallout from the Chernobyl accident caused childhood leukaemia in Europe? An update on epidemiologic evidence

    Energy Technology Data Exchange (ETDEWEB)

    Hoffmann, W. [Bremen Inst. for Prevention Research and Social Medicine (BIPS), Bremen (Germany)

    2001-07-01

    Background: According to radiation risk estimates uniformly adopted by various official organizations, exposure to Chernobyl fallout is unlikely to have caused any measurable health risk in central Europe. Methods and Results: A reevaluation of ECLIS (European Childhood Leukaemia and Lymphoma Incidence Study), a large IARC-coordinated project revealed a slightly higher leukaemia incidence in the most contaminated European regions, and an increasing trend with estimated cumulative excess radiation dose. The excess corresponds to 20 cases of childhood leukaemia in the study area until 1991. Recent evidence from Greece and Germany indicate significantly higher risks in the cohort of children in utero at the time of the initial fallout. In Greece, a positive trend was observed over three regions of increasing average fallout contamination (p=0.005). Conclusion: Chernobyl fallout could well have caused a small, but significant excess of childhood leukaemia cases in Europe. The etiologic mechanism might include an induction of chromosome aberrations in early pregnancy. Increased risks in the birth cohort exposed in utero correspond to 11 excess cases in Greece and another 11.4 excess cases in Germany alone. Exposure misclassification and underascertainment of incident cases render post-Chernobyl risk estimates probably too low. If indeed Chernobyl fallout has caused childhood leukaemia cases in Europe, we would also expect an increased incidence for other childhood cancers and excess malignancies in adults as well as non-malignant diseases of all ages. Neither of these endpoints have as yet been systematically studied. (orig.)

  15. Differences and similarities between behavior of Fukushima-derived and Chernobyl-derived radiocesium in the environment

    The mobility and bioavailability of radiocesium (r-Cs) of accidental origin is governed by the ratio of its chemical forms in fallout and site-specific environmental characteristics determining the rates of leaching, fixation-remobilization, as well as sorption-desorption of the mobile fraction (its solid-liquid distribution). R-Cs in the environment is strongly bound to soil and sediment particles containing micaceous clay minerals (illite, vermiculite, etc.). This is associated with two basic processes - high selective reversible sorption and fixation. Climate and geographical conditions for Fukushima Prefecture of Japan and Chernobyl zone differ. For example, the catchments of the Chernobyl zone are flat and characterized by low slopes, while Fukushima's watersheds are hilly with steep slopes. Annual precipitation also differs substantially, with annual average for Fukushima about 3 times higher than at Chernobyl. The soils on the north-east coast of the Honshu island that were primarily affected by the radioactive contamination from the Fukushima Daiichi nuclear power plant (FDNPP) accident differ significantly from the Chernobyl zone soils. The proportion of clays such as illite, vermiculite etc. is 20-30% at Fukushima, which is higher than in the sandy loam soils of the Chernobyl zone. In addition to the landscape differences, the speciation of r-Cs in fallout was also different between Fukushima and Chernobyl. It is a challenge to compare r-Cs behavior in FDNPP and Chernobyl zones. Comparative analysis has been carried out for r-Cs wash-off parameters and the distribution coefficient Kd in rivers and surface runoff on Fukushima and Chernobyl contaminated areas for the first years after the accidents. The r-Cs distribution coefficient in Fukushima rivers was 1-2 orders of magnitude higher than correspondent values for rivers and surface runoff of the Chernobyl zone. This suggests higher ability of Fukushima soils and sediments to bind r-Cs. The normalized

    The Chernobyl reactor accident in April 1986 caused the release to atmosphere of substantial amounts of radioactivity. Precise estimates of the release vary. The USSR State Committee presented information to a meeting of the International Atomic Energy Agency in August 1986 indicating a release of some 2.9x10{sup 5} TBq {sup 137}Cs and 2x10{sup 5} TBq {sup 90}Sr, with a total fission/activation product release of 1.7x10{sup 6} TBq. Other commentators suggest that up to double this amount may have been released. Estimates of deposition likewise vary, although it is probable that about half the released activity was deposited within 20 km of the release point, predominantly following two plume trajectories to the north and west. This resulted in the death of pine trees over 400 ha, the abandonment of 100,000 to 150,000 ha of agricultural land and the establishment of an exclusion zone extending to 30 km from the site. High levels of radionuclide contamination continue to prevail within the exclusion zone. Nonetheless, over the past fifteen years, re-colonisation has been widespread. Mixed deciduous woodlands, with a high proportion of birch (Betula spp.) and willow (Salix spp.), have become established in the forest areas, while agricultural land has succeeded to tall grassland and scrub. Field sites established in this study exhibited external gamma dose rates varying from 0.1 {mu}Sv h{sup -1} to 140 {mu}Sv h{sup -1}. Corresponding mean concentrations of {sup 137}Cs in the top 20 cm of soil varied from about 6.10{sup 2} to 3.10{sup 6} Bq kg{sup -1} dw. This study summarises observations over the period 2001 to 2004. Sub-surface activity, as measured by bait lamina penetration, appears to be inversely correlated with concentrations of {sup 137}Cs and {sup 90}Sr in soil. Likewise, at the very highest levels of contamination, there is some loss of invertebrate diversity; although little associated change in overall biomass. Between years, population densities and

    2010-05-01

    The European GEO SIF has been initiated by the GIGAS project in an effort to better coordinate European requirements for GEO and GEOSS related activities, and is recognised by GEO as a regional SIF. To help advance the interoperability goals of the Global Earth Observing System of Systems (GEOSS), the Group on Earth Observations (GEO) Architecture and Data Committee (ADC) has established a Standards and Interoperability Forum (SIF) to support GEO organizations offering components and services to GEOSS. The SIF will help GEOSS contributors understand how to work with the GEOSS interoperability guidelines and how to enter their "interoperability arrangements" (standards or other ad hoc arrangements for interoperability) into the GEOSS registries. This will greatly facilitate the utility of GEOSS and encourage significant increase in participation. To carry out its work most effectively, the SIF promotes to form Regional Teams. They will help to organize and optimize the support coming from the different parts of the World and reach out regional and multi-disciplinary Scientific Communities. This will allow to have true global representation in supporting GEOSS interoperability. A SIF European Team is foreseen. The main role of the SIF is facilitating interoperability and working with members and participating organizations as they offer data and information services to the users of GEOSS. In this framework, the purpose of having a European Regional Team is to increase efficiency in carrying out the work of the SIF. Experts can join the SIF European Team by registering at the SIF European Team wiki site: http://www.thegigasforum.eu/sif/

    ENDEF, an initiative of the European Commission, DG XVII (Energy) was well supported by the European industrial institutions working in assistance with nuclear industrial organisations in the CEEC`s (Central and Eastern European Countries) and NIS`s (New Independent States). This Forum provides effectively a platform for open discussion between representatives of industrial actors active in the NDE (Non Destructive Examination)/ISI (In Service Inspection) field with the purpose to establish a co-operation pattern between qualified representatives of the EU (European Union) industry to offer a better co-ordinated and well defined assistance to the CEEC`s and NIS in the field of NDE/ISI, and to lay the ground for further industrial co-operation. ENDEF developed a strategy to follow for the establishment of co-operation projects. This strategy is now used to understand the extent of past or present assistance projects and to identify the areas where more co-operation is needed. ENDEF encourages the creation in the NIS`s and CEEC`s of similar forums in order to increase the co-operation and co-ordination. ENDEF is also working in perfect agreement with the European Network ENIQ, piloted by the European plant operators. This identity of views lead to the leadership by the ENDEF co-ordinator of the ENIQ Task 3 involving Applications of the European Methodology for ISI qualification in the CEEC`s and NIS`s and presently fully integrated in ENDEF.

    Full Text Available Subject of Research.The competitive advantage of a modern specialist is the widest possible coverage of informationsources useful from the point of view of obtaining and acquisition of relevant professionally significant information. Among these sources professional web forums occupy a significant place. The paperconsiders the problem of automaticforum text summarization, i.e. identification ofthose fragments that contain professionally relevant information. Method.The research is based on statistical analysis of texts of forums by means of machine learning. Six web forums were selected for research considering aspects of technologies of various subject domains as their subject-matter. The marking of forums was carried out by an expert way. Using various methods of machine learning the models were designed reflecting functional communication between the estimated characteristics of PSI extraction quality and signs of posts. The cumulative NDCG metrics and its dispersion were used for an assessment of quality of models.Main Results. We have shown that an important role in an assessment of PSI extraction efficiency is played by requestcontext. The contexts of requestshave been selected,characteristic of PSI extraction, reflecting various interpretations of information needs of users, designated by terms relevance and informational content. The scales for their estimates have been designed corresponding to worldwide approaches. We have experimentally confirmed that results of the summarization of forums carried out by experts manually significantly depend on requestcontext. We have shown that in the general assessment of PSI extraction efficiency relevance is rather well described by a linear combination of features, and the informational content assessment already requires their nonlinear combination. At the same time at a relevance assessment the leading role is played by the features connected with keywords, and at an informational content

    The HEDS-UP (Human Exploration and Development of Space-University Partners) program has been instituted to build new relationships between university faculty and students and NASA in support of the Human Exploration and Development of Space. The program provides a mechanism whereby university students can explore problems of interest to NASA through student design projects, led by a university professor or mentor, and aided by the HEDSUP staff. HEDS-UP advises on the type of project that is of interest and provides contacts to NASA and industry professionals who may serve as mentors to the student project. Students become acquainted with objectives, strategies, development issues, and technologic characteristics of space exploration programs. In doing so, they are preparing themselves for future engineering challenges and may well find that the program is on their critical path to professional advancement. Many of the ideas are novel and are of interest to NASA. Industry finds in HEDS-UP a mechanism to meet many bright and enthusiastic students who are about to enter the work force. The universities become more involved with space exploration and the students are encouraged to include an outreach element in their work, to bring their efforts and their excitement to others in their universities or in their communities. The climax of the HEDS-UP program each year is the HEDS-UP Forum, held at the Lunar and Planetary Institute. Here, the university teams bring their projects - written reports, oral reports, models, prototypes, and experiment demonstrations - to show to one another and to NASA and industry participants. NASA, industry, and academic professionals present discussions of problems of current interest to space exploration. All meet informally around the posters that each of the teams brings to the Forum. This year the HEDS-UP Forum was held May 4-5 at the Lunar and Planetary Institute in Houston. Thirteen university teams from twelve universities

    The lowering of the drinking water standard (MCL) for arsenic from 50 {micro}g/L to 10 {micro}g/L in January 2006 could lead to significant increases in the cost of water for many rural systems throughout the United States. The Arsenic Water Technology Partnership (AWTP), a collaborative effort of Sandia National Laboratories, the Awwa Research Foundation (AwwaRF) and WERC: A Consortium for Environmental Education and Technology Development, was formed to address this problem by developing and testing novel treatment technologies that could potentially reduce the costs of arsenic treatment. As a member of the AWTP, Sandia National Laboratories evaluated cutting-edge commercial products in three annual Arsenic Treatment Technology Vendors Forums held during the annual New Mexico Environmental Health Conferences (NMEHC) in 2003, 2004 and 2005. The Forums were comprised of two parts. At the first session, open to all conference attendees, commercial developers of innovative treatment technologies gave 15-minute talks that described project histories demonstrating the effectiveness of their products. During the second part, these same technologies were evaluated and ranked in closed sessions by independent technical experts for possible use in pilot-scale field demonstrations being conducted by Sandia National Laboratories. The results of the evaluations including numerical rankings of the products, links to company websites and copies of presentations made by the representatives of the companies are posted on the project website at http://www.sandia.gov/water/arsenic.htm. This report summarizes the contents of the website by providing brief descriptions of the technologies represented at the Forums and the results of the evaluations.

    2011-07-01

    This review aims to discuss expert systems in general and how they may be used in medicine as a whole and clinical microbiology in particular (with the aid of interpretive reading). It considers rule-based systems, pattern-based systems, and data mining and introduces neural nets. A variety of noncommercial systems is described, and the central role played by the EUCAST is stressed. The need for expert rules in the environment of reset EUCAST breakpoints is also questioned. Commercial automated systems with on-board expert systems are considered, with emphasis being placed on the "big three": Vitek 2, BD Phoenix, and MicroScan. By necessity and in places, the review becomes a general review of automated system performances for the detection of specific resistance mechanisms rather than focusing solely on expert systems. Published performance evaluations of each system are drawn together and commented on critically.

    Research highlights: {yields} {sup 137}Cs and {sup 239,240}Pu move down into the soil profile. {yields} {sup 137}Cs is from Chernobyl fallout; {sup 239,240}Pu is from stratospheric fallout from the 1960s. {yields} Solute transport and bioturbation models describe some but not all of the radionuclide profiles. - Abstract: Vertical profiles of {sup 137}Cs and {sup 239,240}Pu were measured in soils collected from two sites in southern Sweden and three sites in southern Poland and were modeled using both a solute transport model and a bioturbation model to better understand their downward migration. A time series of measured {sup 137}Cs profiles indicates that {sup 137}Cs from Chernobyl was found at the soil surface in 1986 but it has migrated progressively downward into the soil 4.5-25.5 cm since. However, because of dispersion during the migration and mixing following Chernobyl deposition and the much higher activities of {sup 137}Cs from Chernobyl, stratospheric fallout of {sup 137}Cs from the 1960s cannot be identified as a second {sup 137}Cs activity maximum lower in the soil column at any of the sites. Conversely, the {sup 240}Pu/{sup 239}Pu ratio indicates that no Chernobyl-derived Pu is present in any of the cores with the exception of one sample in Sweden. This difference may be attributed to the nature of the release from Chernobyl. Cesium volatilized at the reactor temperature during the accident, and was released as a vapor whereas Pu was not volatile and was only released in the form of minute fuel particles that traveled regionally. Both the solute diffusion and the bioturbation models accurately simulate the downward migration of the radionuclides at some sites but poorly describe the distributions at other sites. The distribution coefficients required by the solute transport model are about 100 times lower than reported values from the literature indicating that even though the solute transport model can simulate the profile shapes, transport as a

  5. Sunlight-exposed biofilm microbial communities are naturally resistant to chernobyl ionizing-radiation levels.

    Directory of Open Access Journals (Sweden)

    Marie Ragon

    Full Text Available BACKGROUND: The Chernobyl accident represents a long-term experiment on the effects of exposure to ionizing radiation at the ecosystem level. Though studies of these effects on plants and animals are abundant, the study of how Chernobyl radiation levels affect prokaryotic and eukaryotic microbial communities is practically non-existent, except for a few reports on human pathogens or soil microorganisms. Environments enduring extreme desiccation and UV radiation, such as sunlight exposed biofilms could in principle select for organisms highly resistant to ionizing radiation as well. METHODOLOGY/PRINCIPAL FINDINGS: To test this hypothesis, we explored the diversity of microorganisms belonging to the three domains of life by cultivation-independent approaches in biofilms developing on concrete walls or pillars in the Chernobyl area exposed to different levels of radiation, and we compared them with a similar biofilm from a non-irradiated site in Northern Ireland. Actinobacteria, Alphaproteobacteria, Bacteroidetes, Acidobacteria and Deinococcales were the most consistently detected bacterial groups, whereas green algae (Chlorophyta and ascomycete fungi (Ascomycota dominated within the eukaryotes. Close relatives to the most radio-resistant organisms known, including Rubrobacter species, Deinococcales and melanized ascomycete fungi were always detected. The diversity of bacteria and eukaryotes found in the most highly irradiated samples was comparable to that of less irradiated Chernobyl sites and Northern Ireland. However, the study of mutation frequencies in non-coding ITS regions versus SSU rRNA genes in members of a same actinobacterial operational taxonomic unit (OTU present in Chernobyl samples and Northern Ireland showed a positive correlation between increased radiation and mutation rates. CONCLUSIONS/SIGNIFICANCE: Our results show that biofilm microbial communities in the most irradiated samples are comparable to non-irradiated samples in

    In today's complex world, we have come to rely increasingly on those who have expertise in specific areas and can bring their knowledge to bear on crucial social, political and scientific questions. Taking the viewpoint that experts are consulted when there is something important at stake for an individual, a group, or society at large, Experts in Science and Society explores expertise as a relational concept. How do experts balance their commitment to science with that to society? How does a society actually determine that a person has expertise? What personal traits are valued in an expert? From where does the expert derive authority? What makes new forms of expertise emerge? These and related questions are addressed from a wide range of areas in order to be inclusive, as well as to demonstrate similarities across areas. Likewise, in order to be culturally comparative, this volume includes examples and discussions of experts in different countries and even in different time periods. The topics include the r...

    The morphometric estimation of parenchyma and stroma condition included the determination of 29 parameters in testicles at 27 persons. The mathematical model of morphogenesis of testicles was created by Bayes' method. The method of differential diagnosis of testicles tissues' changes conditioned by the influence of the Chernobyl factor and/or unfavorable terms of the work in underground coal mines have been worked out. Its practical use provides exactness and reliability of the diagnosis (not less than 95%), independence from the level of the qualification and personal experience of the doctor, allows us to unify, optimize and individualize the diagnostic algorithms, answer the requirements of evidential medicine.

    Over several weeks in 2013, the BZgA pilot project "SoMe" (August 2012 to February 2014) tested and investigated various social media interventions in the fields of family planning and sex education. The interventions included the tool "forum webcare," which was used in four forums for pregnant women and three for young people. The term webcare originally described a customer-oriented communication strategy of the web economy. The term includes elements of reputation management, customer care, and online marketing. In the present pilot project, forum webcare has been understood and applied in the sense of "virtual street work," which means that issues on health topics in non-self-operated forums were identified and answered. The design was based on the Precede-Proceed Model. In the phases of analysis, implementation, and evaluation the project used chronologically and methodologically interlaced and mutually controlling methods such as online test groups, intensive interviews, and the evaluation of data on web use. The analysis indicated that the target groups of the project used the forums quite often; that they had a positive attitude toward the idea of webcare providing contributions from experts working for public institutions; and that the risk of reactance was low. Forum webcare allows important supplementary and well-founded information to be brought into the discussions. At the same time the results of the project show that users, when keeping to certain rules, mostly see webcare as a welcome addition to incomplete information and the improvement of faulty information, and appreciate it as quality enhancement for the forum. From the view of the information provider, forum webcare is more a chance to address numerous passive recipients rather than communicating with single users. At the same time the instrument provides the chance to learn from users of the forums, and to become familiar with and be able to respond to their needs and the way in which they

    Soon after the Chernobyl nuclear accident, the air-pumping stations in Pavia (northern Italy) were alerted. In a few days, a rapid increase in radionuclide concentration in air particulates was observed. Consequently, an environmental radioactivity monitoring programme was started in which several matrices such as soil, grass, vegetables and cows' milk were subjected to direct gamma-ray spectrometry. The radioactivity distribution and its variation with time is presented, discussed and compared with other available data. Detection limits, precision and accuracy are also reported, and depth profiles in soils for {sup 137}Cs are presented and correlated with soil quality parameters. A survey of environmental radioactivity in soil, in a search for residual Chernobyl fallout, was carried out and a map of the {sup 137}Cs distribution over a large area in northern Italy is presented and discussed.

    Concentrations of airborne fission products during the month following the Chernobyl event, were analyzed by gamma-ray counting of 283 air filter samples that were collected at 20 different locations in the western United States. While the presence of {sup 103}Ru, {sup 131}I, {sup 134}Cs and {sup 137}Cs was detected in many of the air filter samples, 78.2-hour {sup 132}Te was detected in only 19 samples all from the sampling stations located in the State of Nevada. The results obtained in this study indicate that the release of {sup 131}I from the Chernobyl reactor was roughly 50 percent greater than that of {sup 137}Cs, while the release of {sup 137}Cs was about 8 times that of {sup 103}Ru and 25 percent greater than that of {sup 132}Te.

    This report discusses the health consequences of the Chernobyl accident. It also highlights the misunderstanding associated with the use by the media of different radioactivity measurement units. It comments some figures about casualties, and the fact that some much higher figures are often stated. It evokes the issue of thyroid cancer in children of the region, discusses other possible public health consequences, the issue of congenital anomalies, the opinion of French physicists on the increase of thyroid cancers in France, and the question of the discrimination between spontaneous and radio-induced cancers. A second part discusses the risk of cancer and its perception in France: validity of the soil contamination assessment, possibility of an accident like Chernobyl and Fukushima in France

    The Chernobyl disaster in 1986 involved the largest airborne release of radioactivity in history, more than 100 times as much radioactivity as the Hiroshima and Nagasaki atomic bombs together. The resulting emergency response, administrative blunders, and subsequent patient outcomes from this large-scale radiological disaster provide a wealth of information and valuable lessons for those who may find themselves having to deal with the staggering consequences of nuclear war. Research findings, administrative strategies (successful and otherwise), and resulting clinical procedures from the Chernobyl experience are reviewed to determine a current utility in addressing the appropriate protocols for a medical response to nuclear war. As various myths are still widely associated with radiation exposure, attention is given to the realities of a mass casualty medical response as it would occur with a nuclear detonation.

  8. Modelling transport and deposition of caesium and iodine from the Chernobyl accident using the DREAM model

    Full Text Available A tracer model, DREAM (the Danish Rimpuff and Eulerian Accidental release Model, has been developed for modelling transport, dispersion and deposition (wet and dry of radioactive material from accidental releases, as the Chernobyl accident. The model is a combination of a Lagrangian model, that includes the near source dispersion, and an Eulerian model describing the long-range transport. The performance of the transport model has previously been tested within the European Tracer Experiment, ETEX, which included transport and dispersion of an inert, non-depositing tracer from a controlled release. The focus of this paper is the model performance with respect to the deposition of 137Cs, 134Cs and 131I from the Chernobyl accident, using different relatively simple and comprehensive parameterizations. The performance, compared to measurements, of different combinations of parameterizations of wet and dry deposition schemes has been evaluated, using different statistical tests.

    Full Text Available The study goal was to investigate thyroid cancer morbidity in population groups affected by the Chernobyl catastrophe. The study period comprised 1994-2006 for clean-up workers and 1990-2006 for Chernobyl evacuees and residents of contaminated territories. A significant increase of thyroid cancer incidence was registered in all observed population groups. The most significant excess over the national level was identified in clean-up workers. This amounted to a factor of 5.9, while it was 5.5 for the evacuees and 1.7 for the residents. The highest thyroid cancer risk was observed in persons exposed to radioiodine in childhood and adolescence.

  10. On the possible physical mechanism of Chernobyl catastrophe and the unsoundness of official conclusion

    2003-01-01

    The official conclusion about the origin and mechanism of the Chernobyl catastrophe is shown to essentially contradict experimental facts available from the accident. In the frame of existing physical models of nuclear fission reactor, it is shown analytically that under conditions of the accident the period of runaway of reactor at the fourth power generating unit of the Chernobyl Nuclear Power Plant (CNPP) should be either 10 times slower or 100 times faster than that observed. A self-consistent hypothesis is suggested for the probable birth of magnetic charges, during the turbine generator test under it's own momentum test, at the fourth power generating unit of CNPP, and for the impact of these charges on the reactivity coefficient.

    Doses from internal and external exposure due to the Chernobyl accident to the Czech population were estimated early in 1986. Later on, with more eimental results, doses from internal exposure were calculated more precisely. The initial predictions were rather conservative leading thus to higher doses than it appeared one year later. Monitoring of the environment, food chain and monitoring of internal contamination has been performed on the whole territory of the country since 1986 up to present time and has thus enabled reevaluation of the original estimates and also prediction of doses in future. This paper is focused mainly on evaluation of in vivo measurements of people. Use of the sophisticate software I.M.B.A. Professional Plus led to new estimation of committed effective doses and calculated inhalation intakes of radionuclides lead to estimation of content of radionuclides in the air. Ingestion intakes were also evaluated and compared with estimates from the results of measurements of food chain. Generally, the doses from the Chernobyl accident to the Czech population were low; however, as a few radionuclides have been measurable in environment, food chain and human body (137 Cs up to present), it is a unique chance for studying behaviour of radionuclides in the biosphere. Experience and conclusions which follow from the monitoring of the Chernobyl accident are unique for running and development of monitoring networks. Re evaluation of internal doses to the Czech population from the Chernobyl accident, using alternative approach, gave generally smaller doses than original estimation; still, the difference was not significant. It was shown that the doses from inhalation of 131 I and 137 Cs were greater than originally estimated, whereas doses from ingestion intake were lower than the originally estimated ones. (authors)

    The spatial distribution of caesium-137 (137Cs) across the land is of much interest because it can tell us about the redistribution of the radionuclide as a result of soil erosion, differential migration through the soil—or its complement, differential retention in the soil. Any such inferences from survey measurements depend on the assumption of a broadly even distribution from weapons testing fallout, and the substantial deposition of 137Cs in rain following the Chernobyl accide...

Biodiversity of phytocenose was studied and species-indicators of radioactive contamination were revealed. The seasonal dynamics of radionuclide content in macrophytes was studied and the role of main aquatic plant clumps in processes of 137Cs and 90Sr distribution in abiotic component of biohydrocenose was demonstrated.

  16. Contaminants in food chains of arctic ungulates: what have we learned from the Chernobyl accident?

    Directory of Open Access Journals (Sweden)

    Birgitta Åhman

    1998-03-01

    Full Text Available The Chernobyl accidenr of 1986 caused radioactive contamination of widespread areas of reindeer pasture in Scandinavia. Reindeer {Rangifer tarandus are especially exposed to radioactive fallout due to their wintet diet, of which lichens are an important part. Much knowledge about the transfer of radiocaesium to reindeer, and via reindeer meat to man, was accumulated by intense scientific investigations, undertaken during the 1960s and 1970s, following nuclear weapons testing. Various ways to reduce the transfer of radiocaesium to animals and humans were also developed during this time. Much of the older knowledge proved to be of great value in the attempts to determine potential consequences of the Chernobyl accident and to suggest possible ways to ameliorate the effects of contamination. After Chernobyl, not only did reindeer prove to be a problem; many other food products originating ftom natural and semi-natural ecosystems were found to accumulate significant amounts of radiocaesium. Intense scientific work has produced new knowledge about the role of ungulates in the transfer of nutrients and contaminants within these systems. Different measures, like providing uncontaminated feed, use of caesium binders, altering the time of slaughter have been used with good results to minimize the transfer of radiocaesium to animals grazing natural pastures. The high cost of countermeasures has enforced consideration of cost against risk, which may also be of general interest with respect to other forms of pollution. Information, introduction of countermeasures and so forth would be more efficient in case a similar accident were to happen again. The Chernobyl accident is an obvious example of how human failures when dealing with a modern technical system can have global consequences and also be a potential threat to what we like to think of as the unspoiled wilderness of the Arctic.

    In this pilot study of those Norwegian individuals most heavily exposed to the Chernobyl Fallout, immunological parameters generally stayed within normal limits. However, some parameter, apparently within the assumed normal range did, in fact correlate to the estimated individual dose as assessed by wholebody counting of radiocaesium content. The small possible effects revealed in this study may represent real biological effects, but do not necessarily represent a health detriment. 43 refs., 4 figs., 6 tabs.

    Effects of long-term, environmentally relevant doses of radiation on biota remain unclear due to a lack of studies following chronic exposure in contaminated environments. The 1986 Chernobyl accident dispersed vast amounts of radioactivity into the environment which persists to date. Despite three decades of research, impacts of the incident on non-human organisms continues to be contested within the scientific literature. The present study assessed the impact of chronic radiation exposure from Chernobyl on the developmental stability of the model aquatic isopod, Asellus aquaticus using fluctuating asymmetry (FA) as an indicator. Fluctuating asymmetry, defined as random deviations from the expected perfect bilateral symmetry of an organism, has gained prominence as an indicator of developmental stability in ecotoxicology. Organisms were collected from six lakes along a gradient of radionuclide contamination in Belarus and the Ukraine. Calculated total dose rates ranged from 0.06-27.1μGy/h. Fluctuating asymmetry was assessed in four meristic and one metrical trait. Significant differences in levels of pooled asymmetry were recorded between sample sites independent of sex and specific trait measured. However, there was no correlation of asymmetry with radiation doses, suggesting that differences in asymmetry were not attributed to radionuclide contamination and were driven by elevated asymmetry at a single site. No correlation between FA and measured environmental parameters suggested a biotic factor driving observed FA differences. This study appears to be the first to record no evident increase in developmental stability of biota from the Chernobyl region. These findings will aid in understanding the response of organisms to chronic pollutant exposure and the long term effects of large scale nuclear incidents such as Chernobyl and Fukushima.

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study. There are also plans for future projects covering areas from psychosocial factors to radiation biology

    Investigations in the post-Chernobyl period (1986-2009) of radiocaesium activity concentrations in Adriatic pilchards are presented. Compared with pre-Chernobyl period, the Chernobyl nuclear accident caused increase of (137)Cs activity concentrations in pilchards. By fitting the measured (137)Cs activity concentrations to the theoretical curve was estimated to be 1.5±0.4 y for 1986-90 and 5.8±0.4 y for 1991-2009 and the bimodal behaviour for the ecological half-life of (137)Cs in pilchards has been observed. Estimated annual effective doses received by (134)Cs and (137)Cs intake due to consumption for an adult member of Croatian population are small. Collective dose for the 1986-2009 period was 4.9+0.3 person-Sv. The observed (134)Cs/(137)Cs activity ratio in pilchards was similar to the ratio that has been found in other environmental samples. The concentration factor for pilchards was roughly estimated to be 93.7±39.2 l kg(-1), which is consistent with the values observed elsewhere.

    Full Text Available Flax (Linum usitatissimum L. is one of the oldest domesticated plants — it was cultivated as early as in ancient Egypt and Samaria 10,000 years ago to serve as a source of fiber and oil, whence it later spread around the world. Compared with other plants, the flax genome consists of a high number of repetitive sequences, middle repetitive sequences and small repetitive sequences of nucleotides. The aim of the study was to analyze the stability of the existing trinucleotides motifs of microsatellite DNA of the flax genome (genotype Kyivskyi, growing in the Chernobyl conditions. The Chernobyl area is the most extensive “natural” laboratory suitable for the study of radiation effects. Over the last 20 years, the researches collected important knowledge about the effects of low and high radiation doses on the DNA isolated from the plant material growing on the remediated fields near Chernobyl and the plant material from fields contaminated by radioactive cesium 137Cs and strontium 90Sr. Using eight pairs of microsatellite primers, we successfully amplified the samples from the remediated fields. For each primer in the control samples and remediated samples, we detected 1 to 3 fragments per locus, each in size up to 120 to 250 base pairs. The applied microsatellite primers confirmed the monomorphic condition of microsatellite loci.

    To provide instrumental validation of radioecological dosimetric models used for estimation of external doses to the Chernobyl population, about 1000 direct dose measurements were conducted in 1996-1997 in 54 settlements in contaminated territories of Ukraine. The areas covered by the measurements have {sup 137}Cs contamination density ranging from 55 to 491 kBq.m{sup -2}. Individual dose measurements were conducted using standard LiF dosemeters, type Harshaw 8814 (TLD-100), and automated TLD system Harshaw 8800. Relatively low contamination and, thus, an unfavourable 'Chernobyl/natural background' dose ratio, called for sophisticated analysis of experimental results. Linear regression of dose relative to {sup 137}Cs contamination density which was conducted in two different ways provided consistent results. Annual background dose, as derived from the results of individual dose measurements, is about 1.1 mSv per annum; the Chernobyl related component is expressed by the rate of 1.24-1.3 {mu}Sv per kBq.m{sup -2} per annum. These results are in reasonable agreement with somewhat conservative modelling parameters which are assumed to be 1.91 {mu}Sv per kBq.m{sup -2} per annum for the case of the rural population.

    Full Text Available The study aimed at radiation contamination impact assessment due to the 1986 Chernobyl accident in Voronezh Region territory more than 600 kilometers away from the ground zero. The major Chernobyl accident impact assessment indicators were the characteristics of 137Cs and 90Sr radionuclides’ soil surface contamination (Ci/km2 as well as the average annual effective dose of critical population group ( mSv/year over 1986–2014. The Population oncological morbidity indicators were analyzed (all malignant neoplasms, including those in thyroid gland, lymphatic and hematopoietic tissue in the territories contrastingly differing on the levels of radiation factor impact. The study covered the period of 2010–2014.It was established that for Voronezh Region territories referred to as the post- Chernobyl radioactively contaminated zone over 29 years period the maximum soil surface contamination by 137Cs and 90Sr radionuclides reduced by 1.90 and 1.91 times (from 3,15 Ci/km2 to 1,66 Ci/km2 and from 0,063 Ci/km2 to 0,0033 Ci/km2, respectively.Currently the relationship was not found between the radioactive contamination density in Voronezh Region and the levels of malignant neoplasms for the local residents.The present situation related to radiation factor impact on Voronezh Region territories remains stable and safe. Mindful of the indicators results the assessment of ionizing sources impact did not identify any exceeding the normative values.

    A cohort of 8,607 Ukrainian Chernobyl clean-up workers during 1986-1987 was formed to study cataract formation after ionizing radiation exposure. Study eligibility required the availability of sufficient exposure information to permit the reconstruction of doses to the lens of the eye. Eligible groups included civilian workers, such as those who built the "sarcophagus" over the reactor, Chernobyl Nuclear Power Plant Workers, and military reservists who were conscripted for clean-up work. Many of the official doses for workers were estimates, because only a minority wore radiation badges. For 106 military workers, electron paramagnetic resonance (EPR) measurements of extracted teeth were compared with the recorded doses as the basis to adjust the recorded gamma-ray doses and provide estimates of uncertainties. Beta-particle doses to the lens were estimated with an algorithm devised to take into account the nature and location of Chernobyl work, time since the accident, and protective measures taken. A Monte Carlo routine generated 500 random estimates for each individual from the uncertainty distributions of the gamma-ray dose and of the ratio of beta-particle to gamma-ray doses. The geometric mean of the 500 combined beta-particle and gamma-ray dose estimates for each individual was used in the data analyses. The median estimated lens dose for the cohort was 123 mGy, while 4.4% received >500 mGy.

    Artificial intelligence (AI) technology, and in particular expert systems, has shown potential applicability in many areas of operation at the Kennedy Space Center (KSC). In an era of limited resources, the early identification of good expert system applications, and their segregation from inappropriate ones can result in a more efficient use of available NASA resources. On the other hand, the education of students in a highly technical area such as AI requires an extensive hands-on effort. The nature of expert systems is such that proper sample applications for the educational process are difficult to find. A pilot project between NASA-KSC and the University of Central Florida which was designed to simultaneously address the needs of both institutions at a minimum cost. This project, referred to as Expert Systems Prototype Training Project (ESPTP), provided NASA with relatively inexpensive development of initial prototype versions of certain applications. University students likewise benefit by having expertise on a non-trivial problem accessible to them at no cost. Such expertise is indispensible in a hands-on training approach to developing expert systems.

  16. Expert witness and Jungian archetypes.

    Science.gov (United States)

    Lallave, Juan Antonio; Gutheil, Thomas Gordon

    2012-01-01

    Jung's theories of archetype, shadow, and the personal and collective unconscious provide a postmodern framework in which to consider the role of the expert witness in judicial proceedings. Archetypal themes, motifs, and influences help to illuminate the shadow of the judicial system and projections and behaviors among the cast of the court in pursuing justice. This article speaks to archetypal influences and dialectical tensions encountered by the expert witness in this judicial drama. The archetype of Justice is born from the human need for order and relational fairness in a world of chaos. The persona of justice is the promise of truth in the drama. The shadow of justice is untruth, the need to win by any means. The dynamics of the trickster archetype serve and promote injustice. These influences are examined by means of a case example. This approach will deepen understanding of court proceedings and the role of the expert witness in the heroic quest for justice.

    EUROSAFE is an international forum for discussions among experts from technical safety organisations, research institutes, safety authorities, utilities, the industry, public authorities and non-governmental organisations concerning the status of and recent achievements in nuclear installation safety, waste management, radiation safety and nuclear material security. The Eurosafe Forum 2003 - the fifth of its kind - was held at the Palais Brongniart in Paris on November 25 and 26, 2003. This year's theme was: 'Nuclear expertise and challenges of the enlargement of the European Union: speakers in the various European countries about the environmental scan before enlargement, development and structuring perspectives within the enlarged Europe'. The event brought together 445 experts and researchers from around the world (including 124 from Germany, 184 from France, 88 from Eastern Europe, as well as representatives from Korea, Japan, the United States, Canada, Cuba, and Armenia. The proceedings of the symposium can now be consulted online. The fifth edition of the forum focused on nuclear expertise and the challenge of EU-enlargement and the latest work carried out by GRS, IRSN and their partners from the European Union, Switzerland and Eastern Europe. Nuclear energy contributes approximately one third of European electricity production. A high level of nuclear safety is a priority for the countries of Europe. The technical safety organisations play an important role in contributing to that objective through appropriate approaches to major safety issues as part of their assessments and research activities. The challenges to nuclear safety are increasingly international.

    Full Text Available It's very important to reward the contributive users of online forums, for that almost all contents are provided by users in such forums. There should be some rewards for contributive users, and rewards should be proportional to the contributions. So the determination and measurement of user contributions are needed in online forums. At the same time, some users may do some fake contributions to obtain more rewards. In this paper, we analyzed possible frauds in online forum, examined features of each kind of fraud, and proposed some fraud-tolerant parameters according the features of frauds. Results of our experiment show that almost 81% users in the examined online forum have fraudulent activities and pure advertising users can be discovered according to the fraud-tolerant parameters we considered. On the other hand, the experiment results also show that the biggest count of fraud type detected is with the parameter minimum intervals of posts from the same users, and followed by the parameter minimum length of posts. While minimum average rate value of post after specified rates is the parameter that was used for least times. Based on the idea of this paper, frauds of user contributions could be discriminated well, and user contributions can be measured quantitatively and fraud-tolerantly, which provides a basis for online forums to reward users in various ways.

    The Fifth Physics and Society Forum, organized by the European Physical Society, will take place at CERN from 28 to 29 March 2012. 
The purpose of the meeting is to explore the challenges experienced by physicists who leave their field of study to pursue alternative careers in the market place outside of teaching and university-based research. 
     It is widely recognized that a knowledgeable society is a prerequisite for growth. Value is only created if knowledge can be transformed into know-how and "know-how-to-do". Today it is widely recognized that a society is unable to grow and sustain an advanced science system unless equally advanced production is present. Today production is off-shored to emerging economies in Asia and elsewhere where labour costs are more favourable. European physicists therefore have the choice of being smarter, working harder and working cheaper or moving into other fields.

    Full Text Available The Commonwealth Local Government Forum (CLGF Pacific Project works with local government and other stakeholders in nine Pacific Island countries – Cook Islands, Fiji Islands, Kiribati, Samoa, Papua New Guinea, Solomon Islands, Tonga, Tuvalu and Vanuatu. It seeks to strengthen local democracy and good governance, and to help local governments deal with the increasing challenges of service delivery and urban management in the unique Pacific environment. Human settlement patterns in the region are changing rapidly. The Pacific has traditionally been a rural agricultural/subsistence society, but this is no longer the case. The accelerated pace of urbanisation has impacted significantly on Pacific nations and in the very near future the majority of Pacific Islanders will be found in urban areas. Already over 50% of Fiji’s population are urban dwellers. Rapid urbanisation brings with it unique challenges and opportunities. Local governments are at the forefront of this phenomenon, with the responsibility to manage urban development and the transition from rural areas to cities and towns. Their success or failure to manage urbanisation and provide the required levels of physical and social infrastructure will affect many lives in a new urban Pacific. The project now has three components – the main Pacific Regional Project and two country-specific programmes: the Honiara City Council Institutional Capacity Building Project and the Commonwealth Local Government Good Practice Scheme in Papua New Guinea.

    Full Text Available Purpose: Attention resource is scarce. Organizing community activities in online forums faces the challenge of attracting users’ limited attention. Understanding how users of online forums allocate, maintain, and change their attentional focus and what features of online forms influence their attention behaviors is critical for effective information design. This paper seeks understanding of users’ attention behaviors and features when they participate in discussions in online forums. Design/methodology/approach: A conceptual model was established to explore the indicator system of attention’s measurement. The related attention data were collected from Alexa Access Statistics Tool and Katie community. Then this paper computed the correlation coefficient and regression relationship between the indicators of visual attention and cognitive attention. Thereafter this paper analyzed and discussed users’ attention behaviors and features in Internet forum. Findings: Relevant bivariate correlation analysis and regression analysis discovers that Internet forum's attention is mainly as visual attention in users’ early involvement. Attention resources can be transformed. In a deep participation, users’ cognitive attention is more significant. Meanwhile cognitive attention behaviors’ further development will lead to the phenomenon that cognitive attention input is prone to increase faster in the early duration. That means in-depth discussion and interaction are more likely to appear in the early stages of participation. Research limitations/implications: There are some limitations about this study. The indicators are not comprehensive enough because factors affecting the distribution of attention resources in Internet forums are complex. We didn’t distinguish different types of Internet forums when we collected the relevant data. Future research will focus more on how to obtain comprehensive attention data.

    This report is a pilot study that systematically describes the various types of expert judgement that are made throughout the development of a PA, and summarizes existing tools and practices for dealing with expert judgements. The report also includes recommendations for further work in the area of expert judgement. Expert judgements can be classified in a number of ways, including classification according to why the judgements are made and according to how the judgements are made. In terms of why judgements are made, there is a broad distinction between: Judgements concerning data that are made because alternatives are not feasible; and Judgements about the conduct of a PA that are made because there are no alternative approaches for making the decision. In the case of how judgements are made, the report distinguishes between non-elicited judgements made by individuals, non-elicited judgements made by groups, and elicited judgements made by individuals or groups. These types of judgement can generally be distinguished by the extent of the associated documentation, and hence their traceability. Tools for assessing judgements vary depending on the type of judgements being examined. Key tools are peer review, an appropriate QA regime, documentation, and elicitation. Dialogue with stake holders is also identified as important in establishing whether judgements are justified in the context in which they are used. The PA process comprises a number of stages, from establishing the assessment context, through site selection and repository design, to scenario and model development and parametrisation. The report discusses how judgements are used in each of these stages, and identifies which of the tools and procedures for assessing judgements are most appropriate at each stage. Recommendations for further work include the conduct of a trial expert elicitation to gain experience in the advantages and disadvantages of this technique, the development of guidance for peer

Contents of the presentations varied widely from an administrative operation of a self-access centre (hereafter SAC to research findings about SAC users. Having approximately 45 people including presenters at the forum, active discussions in which they shared ideas and professional practices were generated. One of the common points which emerged in the forum was that the form of learning that SACs provide is becoming more accepted and valued by educational institutions, and this has led to an increase in the number of SACs nationwide in Japan. Against this background, three themes were evident in the presentations given at this year’s forum: focusing on the physical learning environment, providing easier access to learners, and supporting learning processes.

    Full Text Available Considered an innovation because of its capacity to develop transnational processes, the World Social Forum however also has strong local roots as well as effects on organizational models and collective identities at the domestic level. Focusing on the Italian case, this article shows how local social forums, as arenas for exchanges of ideas, played a cognitive role in the import, but also the translation of new ideas, as well as helping the emergence of dense network structures and tolerant identities. The first section of the article examines how local social forums contributed to innovation in the organizational formulas of the Global Justice Movement—considering both structure (organizations and process (methodologies aspects—through the development of different, more participatory conceptions of internal decision making. It then addresses the innovations in the definition of collective identities, stressing the linkages of local struggles and global framing as well as the development of a cross-issue discourse around an anti-neoliberal frame. The final section will discuss the contribution of local social forums to contemporary social movements, stressing the role of these new arenas for the cross-fertilization among different movement families and spreading a method of working together that becomes part of the repertoire of action of local social movement organizations. The empirical research consists mainly of in-depth interviews and focus groups with activists from social movement organizations which were involved in local social forums.

    2013-12-01

    Full Text Available This article assesses socialization in the Eastern Partnership Civil Society Forum, an institutionalized civil society cooperation consisting of nongovernmental organizations from the European Union and the Eastern Partnership countries: Belarus, Ukraine, Moldova, Georgia, Armenia, and Azerbaijan. The article argues that uniting the literature on socialization and on Eastern Partnership Civil Society Forum adds considerably to scholarly knowledge about the role of the institutionalized civil society in the world. The analysis of the activities of the Civil Society Forum shows that the conditions for socialization are largely fulfilled. We conclude that the organisation and functioning of the Eastern Partnership Civil Society Forum not only provides a passive framework for transmitting European values and norms, but also results in a middle degree of socialization between civil society organizations of the European Union and the Eastern Partnership countries. There is a large degree of internalization of European Union-sponsored norms and values among the participants of the Civil Society Forum: they fervently promote and defend such norms and values. The little-politicized environment in which discussions take place also allows civil society organisations to make ambitious statements, often more straightforward than political representatives (can make.

    Six questions to the experts in the field are posed: (1) Why is the assessment of accident consequences not separated in long-term and peak exposure? (2) Why is the exposure due to I-131 seen critical mainly in regard to the thyroid? (3) Do you have any reliable relations of health risk versus peak exposure? (4) Why do you not abolish the LNT assumption and replace it with a threshold model? (5) Why do you include indirect, psycho-somatic effects in assessing the consequences of reactor accidents when this is not customary with accidents with often more casualties? (6) How can the number of Chernobyl-assigned thyroid cancers have risen from some 600 about to some 4,000 today, when the latency period is in the range of 4 to 5 years?.

    Full Text Available Albumin is the most generously represented protein in human blood plasma. Therefore it is important to follow and assess the transport function of albumin in clinic researches. Disturbances in structural/functional properties of albumin play an important role in the pathogenesis of various diseases and immune state in patients. Changes in albumin transformation can serve as a diagnostic and prognostic criterion in pathologies. ABM (3-aminobenzanthrone derivative developed at the Daugavpils University, Latvia has been previously shown as a potential biomarker for determination of the immune state of patients with different pathologies. The aim of this study was to determine the several aspects of plasma albumin alterations in the group of Chernobyl clean-up workers in long term period in relation with humans having no professional contact with radioactivity. The following parameters were examined: (1 spectral characteristics of ABM in blood plasma; (2 and #8216;effective and #8217; and total albumin (EA and TA concentration in blood plasma; (3 quantitative parameters of albumin auto-fluorescence; (4 albumin binding site characteristics. Screening of the individuals with a period of 25-26 years after the work in Chernobyl revealed two groups of patients differing in structural and functional albumin properties; first on conformations of plasma albumin, and second characteristics of tryptophanyl region of the molecule. The revealed structural modifications of albumin are dependent on radiation-induced factors. Concomitant diseases such as diabetes mellitus or cardio-vascular diseases reinforce radiation-induced effects. In conclusion, ABM is a sensitive probe for albumin alterations and can be used to elucidate the changes in protein systems. Significant differences in albumin dynamics exist between control (donors and groups of Chernobyl clean-up workers. [J Exp Integr Med 2014; 4(3.000: 165-170

    The ICRP models used in radiation protection to estimate doses resulting from internal irradiation are based on biokinetic models for different radionuclides. Strontium-90 was one of the main sources of environmental contamination due to accidents in the ''Mayak'' plutonium production complex (Southern Urals, 1949-1956) and the Chernobyl accident (1986). Over 800 measurements of bone-autopsy, and 31,000 Whole body Counter {sup 90}Sr measurements for Techa River population were made at URCRM (Chelyabinsk). Measurements of {sup 90}Sr contents in skeleton were performed for residents of the area contaminated due to Chernobyl accident (RPI, Kiev). These unique data allowed to validate the predictions of {sup 90}Sr biokinetic models at different times after ingestion, and in the case of complicated rate of intake. Model validation can be considered as best approach for quantifying the reliability of the model's predictions. Available data on {sup 90}Sr content in human skeleton were analyzed. {sup 90}Sr measurements cover the long period after start of intake: from 2 to 45 years after contamination (Techa River data). Model predictions for all age groups were compared with Techa River and Chernobyl data. For adult persons calculated and measured values of {sup 90}Sr body content were found to be very close, especially over the first 15 years after the major intake. After the majority of measured people had attained the age of 45 years and changes of calcium metabolism resulted in a significant increase of strontium elimination rate. The particularities of bone mineral turnover in old persons are not considered in the framework of the ICRP model. The latter feature resulted in a divergence between the model curve and the results of {sup 90}Sr measurements for old persons. For children and adolescents the differences between calculated values and measured {sup 90}Sr body contents are more significant. The comparison of different strontium

    The Chernobyl nuclear accident happened in the former Soviet Union on 26 April 1986. The accident destroyed one of the RBMK-1000 type reactors and released significant radioactive contamination into the environment. At first the emissions were transported north-westwards over Poland, the Baltic States, Finland, Sweden and Norway. During 27 April 1986 emissions were spreading to eastern-central Europe, southern Germany, Italy and Yugoslavia. Radioactivity mapping over Finland between 29 April and 16 May 1986 showed that the ground deposition in Finland covered southern and central parts of the country but had an irregular distribution. The highest (over 100 muR h-1 [1 muSv h-1]) contamination disclosed by the mapping was around the city of Uusikaupunki in western Finland and the city of Kotka in southeastern Finland. The Uusikaupunki region was an area of heavy fallout associated with the air mass that was located in the Chernobyl area at the time of the accident. The fallout pattern of reftractory nuclides, e.g. plutonium isotopes, had their spatial maximum in this region. Medical consequences in Finland were luckily mild, the most important symptoms being psychological ones. No increase in thyroid cancer or birth defect occurrence has been observed. The Chernobyl accident boosted the radioecological research which had already been calming down after the last atmospheric nuclear test in China in October 1980. Important new results concerning e.g. hot particles have been achieved. The most important effects of the accident in Finland were, however, the increase of public awareness of environmental issues in general and especially of nuclear energy. In Finland, the nuclear energy programme was halted until 2002 when the Parliament of Finland granted a licence to build the fifth nuclear reactor in Finland. (orig.)

    The consequences of two largest nuclear accidents of the last decades - at Chernobyl Nuclear Power Plant (ChNPP) (1986) and at Fukushima Daiichi NPP (FDNPP) (2011) clearly demonstrated that radioactive contamination of water bodies in vicinity of NPP and on the waterways from it, e.g., river- reservoir water after Chernobyl accident and rivers and coastal marine waters after Fukushima accident, in the both cases have been one of the main sources of the public concerns on the accident consequences. The higher weight of water contamination in public perception of the accidents consequences in comparison with the real fraction of doses via aquatic pathways in comparison with other dose components is a specificity of public perception of environmental contamination. This psychological phenomenon that was confirmed after these accidents provides supplementary arguments that the reliable simulation and prediction of the radionuclide dynamics in water and sediments is important part of the post-accidental radioecological research. The purpose of the research is to use the experience of the modeling activities f conducted for the past more than 25 years within the Chernobyl affected Pripyat River and Dnieper River watershed as also data of the new monitoring studies in Japan of Abukuma River (largest in the region - the watershed area is 5400 km{sup 2}), Kuchibuto River, Uta River, Niita River, Natsui River, Same River, as also of the studies on the specific of the 'water-sediment' {sup 137}Cs exchanges in this area to refine the 1-D model RIVTOX and 2-D model COASTOX for the increasing of the predictive power of the modeling technologies. The results of the modeling studies are applied for more accurate prediction of water/sediment radionuclide contamination of rivers and reservoirs in the Fukushima Prefecture and for the comparative analyses of the efficiency of the of the post -accidental measures to diminish the contamination of the water bodies.

    The results of the French-German Initiative Health Effects project, conducted over a period of four years, were presented to the international authorities at a congress held in October 2004 in Kiev and are summarised below. Thyroid cancer increase in children and young adults seems clearly related to exposure at young ages in 1986. For the other cancers sites, the observed results do not add any decisive elements that would make it possible to quantify the impact of post-Chernobyl irradiation: the trend observed in time is similar in both exposed and non-exposed areas in most situations. These observations do not exclude the fact that an increase of leukaemia may exist for those exposed as children; it may be too low to be detectable in a statistically significant way. Similarly, the higher rate of congenital malformations observed during recent years cannot be attributed to radiation, because the same trend over time is observed both in contaminated and non-contaminated areas in Belarus. Reliable and up-to-date knowledge has been collected in a H.E.D.A.C. database, it should facilitate communication concerning the health impact of the Chernobyl accident. The main results published at national or international level, will be made available to the public and the international scientific community via modern distribution methods and will contribute to the development of a necessary cohesion between international research programmes and work carried out locally. Contact the web site: www.fgi.icc.gov.ua For detailed information, final reports are available: contact with mentioned investigators is proposed (see authors of final reports) or contact scientific coordinator M.

    The reactor accident at Chernobyl in 1986 beside its serious and tragic consequences provided also an excellent opportunity to check, test and validate all kind of environmental models and calculation tools which were available in the emergency preparedness systems of different countries. Assessment of internal and external doses due to the accident has been carried out for the population all over Europe using different methods. Dose predictions based on environmental model calculation considering various pathways have been compared with those obtained by more direct monitoring methods. One study from Hungary and one from the TAEA is presented shortly. (orig./DG)

    The atmospheric dispersion models have been developed to predict and minimize the radiological damage for the surrounding environment since the Chernobyl accident. There are many nuclear power plants in the region of Northeast Asia. It is necessary to develop a long-range atmospheric dispersion model for the radiological emergency preparedness against a nuclear accident. From this viewpoint, a Lagrangian particle model named L.A.D.A.S.(Long-range Accident Dose Assessment System) was initially developed for the evaluation the long-range dispersion in Korea since 2001. The model designed to estimate air concentrations and dry deposition as well as wet deposition at distances up to some thousands of kilometers from the source point in a horizontal direction. The validation study of the model was firstly performed by comparing the measured values of E.T.E.X. exercise. The developed model was also applied to simulate the movements of the radioactive materials at the Chernobyl accident. An intercomparison and validation study among the long-range models was performed through the A.T.M.E.S.(Atmospheric Transport Model Evaluation Study) project under auspices of the IAEA/W.M.O. (world meteorological organization) in 1992. As a consequence of A.T.M.E.S., it was observed that in a real emergency case, under conditions of urgency and stress, many of the models would have had different results. So, one of the main recommendations was the launch of a long-range atmospheric tracer experiment in conditions as close as possible to those which could be found in a real emergency case, with the advantage of a complete knowledge of the source term. In this study, numerical simulations were carried out to estimate the concentration distributions of {sup 137}Cs. The calculated results agreed well with them by Chernobyl accident. In conclusion, a three dimensional Lagrangian particle model named L.A.D.A.S. was developed to evaluate the characteristics of a long-range atmospheric

    Species of wild herbaceous plants growing over a period of 3 years under chronic irradiation resulting from the Chernobyl accident were studied. Examining the mass of 1000 seeds and their germination did not yield any significant differences between groups of seeds of the same species collected from the different contaminated zones. Nor did the frequency of aberrant cells in roots of germinated seeds reveal any significant differences between the zones. Seeds of Plantago lanceolata growing in areas with higher levels of radiation, did appear to be more sensitive to additional gamma-irradiation. (author). 5 refs.; 7 figs.; 5 tabs.

    The input from 'Chernobyl' can be distinguished from other sources of artificial radionuclides, such as the reprocessing plants at La Hague and Sellafield, by its characteristic nuclide spectrum. The input occurred to quite different strength of activity in the different areas of the North Sea and the Baltic Sea; a rapid vertical dilution within the water column resulted in a rapid decrease of the initial activity concentration. The sediments are contaminated by the vertical transport of sinking suspended particulate matter, which adsorb the activity from the surrounding water.

    A comparative twenty-year study of 536 liquidators of the Chernobyl nuclear disaster and 436 patients without radiation anamnesis has been carried out. Discirculatory encephalopathy (DE) was more often developed in subjects exposed to radiation at the age 30 years. Compared to individuals from the general population, it is characterized by the earlier onset, malignant progression, rapid increase of signs of cerebral affection during the first two years after exposure to radiation, stability of clinical symptoms during the following 5-6 years and further progressive cerebral decompensation with early autonomic dysfunction, psychoorganic syndrome, epilepsy. Moreover, severe stroke is a common complication of DE in liquidators.

    Full Text Available The article describes radiation conditions in the Kaluga region 30 years after the Chernobyl NPP accident. The Chernobyl NPP accident caused radioactive contamination of nine Kaluga region territories: Duminichsky, Zhizdrinsky, Kuibyshevsky, Kirovsky, Kozelsky, Ludinovsky, Meshchovsky, Ulyanovsky and Hvastovichsky districts. Radioactive fallout was the strongest in three southern districts: Zhizdrinsky, Ulyanovsky and Hvastovichsky, over there cesium-137 contamination density is from 1 to 15Ci/km. According to the Russian Federation Government Order in 2015 there are 300 settlements (S in the radioactive contamination zone, including 14 settlements with caesium-137 soil contamination density from 5 to 15 Ci/ km2 and 286 settlements with the contamination density ranging from 1 to 5 Ci/km2. In the first years after the Chernobyl NPP accident in Kaluga region territories, contaminated with caesium-137, there were introduced restrictive land usage, were carried out agrochemical activities (ploughing, mineral fertilizer dressing, there was toughened laboratory radiation control over the main doze-forming foodstuff. All these measures facilitated considerable decrease of caesium-137 content in local agricultural produce. Proceeding from the achieved result, in 2002 there took place the transition to more tough requirements SanPiN 2.3.2.1078-01. Analysis of investigated samples from Zhizdrinsky, Ulyanovsky and Hvastovichsky districts demonstrated that since 2005 meat samples didn’t exceed the standard values, same for milk samples since 2007. Till the present time, the use of wild-growing mushrooms, berries and wild animals meat involves radiation issues. It was demonstrated that average specific activity of caesium-137 in milk samples keeps decreasing year after year. Long after the Chernobyl NPP accident, the main products forming internal irradiation doses in population are the wild-growing mushrooms and berries. Population average annual

    Full Text Available As the result of the Chernobyl NPP accident more than 200 thousand square kilometers of the European territories were contaminated by Cs-137 in the amount of above 37 kBq/m2 (1 Ci/km2 . Belorussia, Russia and Ukraine amount up to 70% of this entire affected area. More than 600 000 people were engaged in the accidental cleanup operations, 340000 were evacuated or relocated within 1986-1991. The early stage evacuation efficacy is confirmed by the absence of acute radiation syndrome among the population and by the prevented collective dose which amounts to no less than 10 000 man/Sv. The effective measure to reduce the internal radiation dose to the population at the early accidental stage was introduction of maximum tentative permissive levels of radionuclide content in the foodstuffs.Among the identified post -accident medical consequences of the Chernobyl is the radiation syndrome found in 134 emergency cleanup workers within the first 24 hours of the accident’s development. Out of that number, 28 people died within the first four months, 19 people died before 2006. The accident’s liquidators developed radiation -induced leukemia ( the attributive risk value is 45-60% . People exposed to high radiation doses display the statistically significant 18% morbidity increase of all types of solid cancers at the doses above 150 mSv. There is the statistically significant information indicating the increased amount of thyroid cancer morbidity among those who were just children and teenagers at the time of the accident. The adverse psychological consequences are accounted for not just the fear of overexposure but also for the disturbance of the habitual lifestyle especially mindful of the forced relocation.The longterm protection measures, radionuclide decay and selfcleaning of the contaminated areas resulted in the drastic reduction of the population dose in the radioactively contaminated territories. In 2015, only in some settlements of the Briansk

    Science education reform since the mid-1990's has called for a "new way of teaching and learning about science that reflects how science itself is done, emphasizing inquiry as a way of achieving knowledge and understanding about the world" (NRC, 1996). Scientists and engineers, experts in inquiry thinking, have been called to help model these practices for students and demonstrate scientific habits of mind. The question, however, is "how best to involve these experts?" given the very real challenges of limited availability of scientists, varying experience with effective pedagogy, widespread geographic distribution of schools, and the sheer number of students involved. Technology offers partial solutions to enable Student-Scientist Interactions (SSI). The FLEXE Project has developed online FLEXE Forums to support efficient, effective SSIs, making use of web-based and database technology to facilitate communication between students and scientists. More importantly, the FLEXE project has approached this question of "how best to do this?" scientifically, combining program evaluation with hypothesis-based research explicitly testing the effects of such SSIs on student learning and attitudes towards science. FLEXE Forums are designed to showcase scientific practices and habits of mind through facilitated interaction between students and scientists. Through these Forums, students "meet" working scientists and learn about their research and the environments in which they work. Scientists provide students with intriguing "real-life" datasets and challenge students to analyze and interpret the data through guiding questions. Students submit their analyses to the Forum, and scientists provide feedback and connect the instructional activity with real-life practice, showcasing their activities in the field. In the FLEXE project, Forums are embedded within inquiry-based instructional units focused on essential learning concepts, and feature the deep-sea environment in contrast

    Full Text Available Abstract The human-animal bond has been a fundamental feature of mankind's history for millennia. The first, and strongest of these, man's relationship with the dog, is believed to pre-date even agriculture, going back as far as 30,000 years. It remains at least as powerful today. Fed by the changing nature of the interactions between people and their dogs worldwide and the increasing tendency towards close domesticity, the health of dogs has never played a more important role in family life. Thanks to developments in scientific understanding and diagnostic techniques, as well as changing priorities of pet owners, veterinarians are now able, and indeed expected, to play a fundamental role in the prevention and treatment of canine disease, including canine vector-borne diseases (CVBDs. The CVBDs represent a varied and complex group of diseases, including anaplasmosis, babesiosis, bartonellosis, borreliosis, dirofilariosis, ehrlichiosis, leishmaniosis, rickettsiosis and thelaziosis, with new syndromes being uncovered every year. Many of these diseases can cause serious, even life-threatening clinical conditions in dogs, with a number having zoonotic potential, affecting the human population. Today, CVBDs pose a growing global threat as they continue their spread far from their traditional geographical and temporal restraints as a result of changes in both climatic conditions and pet dog travel patterns, exposing new populations to previously unknown infectious agents and posing unprecedented challenges to veterinarians. In response to this growing threat, the CVBD World Forum, a multidisciplinary group of experts in CVBDs from around the world which meets on an annual basis, gathered in Nice (France in 2011 to share the latest research on CVBDs and discuss the best approaches to managing these diseases around the world. As a result of these discussions, we, the members of the CVBD Forum have developed the following recommendations to veterinarians

    This ethnographic study evaluated the use of low-bandwidth web-conferencing to enhance diffusion of a specific best practice, the Ponseti method to treat clubfoot, in three economically diverse countries in Latin America. A "Ponseti Virtual Forum" (PVF) was organized in Guatemala, Peru and Chile to examine the influences of economic level and telecommunication infrastructure on the effectiveness of tins approach. Across the three countries, a total of 14 different sites participated in the PVFs. Thirty-three Ponseti-trained practitioners were interviewed before and after each PVF, which included interactions with a Spanish-speaking Ponseti method expert. Semi-structured interviews, observations, and IP address data were triangulated and analyzed. The results demonstrated that 100% of the practitioners rated the sessions as very useful and that they would use this approach again. The largest obstacles to using PVFs were financial (7 out of 9 practitioners) in Guatemala; a lack of equipment and network access (6 out of 11) in Peru; and the organization and implementation of the conferences themselves (7 out of 9) in Chile. This study illustrates the usefulness of Ponseti Virtual Forums in Latin America. Health officials in Peru are currently developing a large-scale information session for traumatologists about the Ponseti method, while practitioners in Guatemala and Chile are organizing monthly scholarly meetings for physicians in remote areas. This initial feedback suggests that low-bandwidth web-conferencing can be an important vehicle for the dissemination of best practices, such as the Ponseti method, in developing countries.

    1999-11-01

    This paper takes a Health Education perspective to analyze a debate forum on the Brazilian Internet site entitled "Universo On-Line", in which the following questions were addressed: "Do you believe that marijuana is harmful to one's health?" "In your opinion, should marijuana use be decriminalized?" By applying qualitative discourse analysis techniques to responses from the forum, we were able to identify six main types of discourse, reflecting the opinions of six "collective subjects" concerning drugs, health, disease, and freedom and existing as social representations in the current Brazilian collective imagination. Research on these social representations allows one to establish criteria for intervention in the field of Health Education.

    Bond, Leonard J.; Brenchley, David L.

    2011-09-01

    In almost all countries with nuclear power plants (NPPs), regulatory authorities and the nuclear industry are looking at some form of extended operating periods. To support life extension activities it is necessary to ensure the continued safety and reliability of system, structures, and components, and the component materials. Internationally, a variety of individual national and international activities have been initiated including Plant Life Management through the International Atomic Energy Agency, Electric Power Research Institute’s Long Term Operation program, and various national programs in managing materials degradation and related topics. The U.S. Nuclear Regulatory Commission (NRC) engaged the international community in workshops in 2005-2006 to identify research needs and to collect information in an expert panel report on Proactive Management of Materials Degradation (PMMD), which was reported in NUREG/CR-6923. These results are also available via an Information Tool on the internet at http://pmmd.pnl.gov. This information builds on the extensive compilations known as the GALL Report (Generic Aging Lessons Learned, NUREG-1801, Vols. 1 and 2). Pacific Northwest National Laboratory (PNNL) recently issued a report on the review of various international activities in PMMD (PNNL-17779). There have also been initiatives by Electricite de France, Tokyo Electric Power Company, EPRI, and others to establish a "Materials Aging Institute." Within the materials degradation research community there are also networks and technical meetings focused on some elements of PMMD. In spite of all these efforts, there is currently no forum to bring together these diverse activities and provide coordinated information exchange and prioritization of materials aging management/PMMD topics. It is believed that the International Forum for Reactor Aging Management (IFRAM) would be a good way to achieve this goal and help develop new approaches for ensuring continued safe

    2011-10-01

    The U.S. marine energy industry is actively pursuing development of offshore wind and marine hydrokinetic (MHK) energy systems. Experience in the wind energy sector demonstrates that new technology development requires thorough measurement and characterization of the environmental conditions prevalent at installation sites and of technology operating in the field. Presently, there are no turn-key instrumentation system solutions that meet the measurement needs of the marine energy industry. The 1st Advanced Marine Renewable Energy Instrumentation Experts Workshop brought together technical experts from government laboratories, academia, and industry representatives from marine energy, wind, offshore oil and gas, and instrumentation developers to present and discuss the instrumentation needs of the marine energy industry. The goals of the meeting were to: (1) Share the latest relevant knowledge among technical experts; (2) Review relevant state-of-the-art field measurement technologies and methods; (3) Review lessons learned from recent field deployments; (4) Identify synergies across different industries; (5) Identify gaps between existing and needed instrumentation capabilities; (6) Understand who are the leading experts; (7) Provide a forum where stakeholders from the marine energy industry could provide substantive input in the development of new marine energy field deployable instrumentation packages.

    The data collected and processed within the framework of the French-German Initiative are an excellent basis for the intended specialist application at the Chernobyl Centre as well as for an extended use in connection with the restoration of the Sarcophagus as part of the 'Shelter Implementation Plan' performed under the auspices of the European Bank for Reconstruction and Development. The major goals of the S.I.P. are the stabilisation of the existing Sarcophagus and the erection of a New Safe Confinement (N.S.C.) around the already existing Sarcophagus, the degasifier wing and the turbine building.This N.S.C. is to safely confine the radioactive materials for at least 100 years and is to allow their retrieval from inside if need be as well as the dismantling of the old structure.In addition, the database can be used for obtaining information needed for project descriptions, safety analysis reports, etc. The Ukrainian safety authority S.N.R.C.U. (State Nuclear Regulatory Committee of Ukraine) and its technical safety organisation, the State Scientific-Technical Center (S.S.T.C.), have also signaled their interest in using the database.Further information on the F.G.I. and on the 'Radioecology and Health Programmes' can be found at: www.fgi1-chernobyl.de.vu; www.grs.de, www.irsn.fr; www.fgi.icc.gov.ua.

    The Chernobyl nuclear power plant accident in Ukraine in 1986 led to widespread radioactive releases into the environment - primarily of radioiodines and cesium - heavily affecting the northern portions of the country, with settlement-averaged thyroid doses estimated to range from 10 mGy to more than 10 Gy. The increased risk of thyroid cancer among exposed children and adolescents is well established but the impact of radioactive contamination on the risk of other types of cancer is much less certain. To provide data on a public health issue of major importance, we have analyzed the incidence of non-thyroid cancers during the post-Chernobyl period in a well-defined cohort of 13,203 individuals who were cancers identified through linkage with the National Cancer Registry of Ukraine for the period 1998 through 2009. We compared the observed and expected number of cases in three cancer groupings: all solid cancers excluding thyroid, leukemia, and lymphoma. Our analyses found no evidence of a statistically significant elevation in cancer risks in this cohort exposed at radiosensitive ages, although the cancer trends, particularly for leukemia (SIR=1.92, 95% confidence interval: 0.69; 4.13), should continue to be monitored.

  3. Workshop on short-term health effects of reactor accidents: Chernobyl

    1986-08-08

    The high-dose early-effects research that has been continued has been done in the context of infrequent accidents with large radiation sources and the use of bone marrow transfusions for treating malignancies, especially leukemia. It thus seemed appropriate to bring together those who have done research on and have had experience with massive whole-body radiation. The objectives were to review what is known about the acute effects of whole-body irradiation, to review the current knowledge of therapy, and particularly of the diagnostic and immunologic problems encountered in bone marrow therapy, and to compare this knowledge with observations made to date on the Chernobyl accident radiation casualties. Dr. Robert Gale, who had helped to care for these casualties, was present at the Workshop. It was hoped that such a review would help those making continuing clinical and pathological observations on the Chernobyl casualties, and that these observations would provide a basis for recommendations for additional research that might result in improved ability to manage successfully this type of severe injury.

    This work is devoted to the reconstruction of time-dependent radioactive contamination fields in the territory of Ukraine in the initial period of the Chernobyl accident using the model of atmospheric transport LEDI (Lagrangian-Eulerian DIffusion model). The modelling results were compared with available {sup 137}Cs air and ground contamination measurement data. The {sup 137}Cs atmospheric transport over the territory of Ukraine was simulated during the first 12 days after the accident (from 26 April to 7 May 1986) using real aerological information and rain measurement network data. The detailed scenario of the release from the accidental unit of the Chernobyl nuclear plant has been built (including time-dependent radioactivity release intensity and time-varied height of the release). The calculations have enabled to explain the main features of spatial and temporal variations of radioactive contamination fields over the territory of Ukraine on the regional scale, including the formation of the major large-scale spots of radioactive contamination caused by dry and wet deposition.

    Levels of /sup 137/ caesium were monitored in northern Sweden during the first year after the Chernobyl accident (April 1986). Samples were collected from 3661 moose in an area where the deposited /sup 137/ caesium ranged from two to 60 kilo-becquerel per m/sup 2/. Concentrations of caesium in moose muscle correlated positively with the ground deposition of caesium. On average, the caesium levels found in moose after Chernobyl were about 470 Bq per kg fresh mass for calves and close to 300 for older animals. The average level in moose before the accident was 33 Bq per kg. Among moose older than one year, higher concentrations were found in females than in the males. There was a pronounced seasonal variation in the /sup 137/ caesium concentration found in moose. Within the investigation area the presence of caesium in moose resulted in a minor proportion of the hunters discarding the animals shot and/or terminating the hunt before the end of the season.

    For nearly 30 years, despite of chronic radiation, flora in Chernobyl zone continue to flourish, evidencing the adaptation of plants to such an environment. Keeping in mind interplanetary missions, this phenomenon is a challenge for plant space research since it highlights the possible mechanisms of genome protection and stabilization in harmful environment. Plants are sessile organisms and, contrary to animals, could not escape the external impact. Therefore, plants should evolve the robust system allowing DNA-protection against damage, which is of special interest. Our investigations show that Arabidopsis thaliana from Chernobyl zone tolerate radiomimetics and heavy metals better than control plants from non-polluted areas. Besides, its genome is less affected by such mutagens. qPCR investigations have revealed up-regulation of some genes involved in DNA damage response. In particular, expression of ATR is increased slightly and downstream expression of CycB1:1 gene is increased significantly after bleomycin treatment suggesting role of ATR-dependent pathway in genome stabilization. Several DNA repair pathways are known to exist in plants. We continue investigations on gene expression from different DNA repair pathways as well as cell cycle regulation and investigation of PCD hallmarks in order to reveal the mechanism of plant tolerance to radiation environment. Our investigations provide unique information for space researchers working on biotechnology of radiation tolerant plants.

    Studies on vertical migration of Chernobyl-origin radionuclides in the 5-km zone of the Chernobyl Nuclear Power Plant (ChNPP) in the area of the Red Forest experimental site were completed. Measurements were made by gamma spectrometric methods using high purity germanium (HPGe) detectors with beryllium windows. Alpha-emitting isotopes of plutonium were determined by the measurement of the x-rays from their uranium progeny. The presence of {sup 60}Co, {sup 134,137}Cs, {sup 154,155}Eu, and {sup 241}Am in all soil layers down to a depth of 30 cm was observed. The presence of {sup 137}Cs and {sup 241}Am were noted in the area containing automorphous soils to a depth of 60 cm. In addition, the upper soil layers at the test site were found to contain {sup 243}Am and {sup 243}Cm. Over the past ten years, the {sup 241}Am/{sup 137}Cs ratio in soil at the experimental site has increased by a factor of 3.4, nearly twice as much as would be predicted based solely on radioactive decay. This may be due to 'fresh' fallout emanating from the ChNPP Confinement Shelter.

    Remediation of soil contaminated with {sup 137}Cs remains one of the most challenging tasks after the Chernobyl 1986 accident. The objectives of this research were to (1) identify extractants that may be used to solubilize {sup 137}Cs in soil solution, (2) study the effect of soil amendments on {sup 137}Cs accumulation by plants, and (3) evaluate the applicability of phytoextraction for environmental restoration of soil contaminated with {sup 137}Cs. The availability of {sup 137}Cs to the plants in Chernobyl soil was limited, because this radionuclide was tightly bound to exchange sites of soil particles or incorporated into the crystalline structure of primary and secondary minerals. Out of 20 soil amendments tested to increase {sup 137}Cs desorption/solubility in the soil, ammonium salts were found to be the most practical soil amendment that can potentially increase {sup 137}Cs bioavailability. Among the screened plants, Amaranth cultivars had the highest {sup 137}Cs accumulation. Three sequential crops of Indian mustard grown in one vegetation season at the experimental plot resulted in a small decrease of {sup 137}Cs specific activity within the top 15 cm of soil. Further improvements are necessary to make phytoremediation technology a feasible option for restoration of {sup 137}Cs-contaminated territories.

    Systematic investigations of 137Cs and 134Cs activity concentrations in potatoes (Solanum tuberosum) for the post-Chernobyl period (1986-2005) in the Republic of Croatia are summarized. The correlation between 137Cs activity concentrations in fallout and potatoes, has been found to be very good, the correlation coefficient being r2=0.88 with P(t) < 0.001 for 18 degrees of freedom. As the radiocaesium levels in potatoes decreased exponentially, the mean residence time of 137Cs in potatoes was estimated by fitting the measured activity concentrations to the exponential curve. The mean residence time was found to be 6.8 +/- 1.1 years, the standard deviation being estimated by the Monte Carlo simulations. The initial observed 134Cs:137Cs activity ratio in potatoes has been found to be quite variable, but slightly lesser than theoretically predicted value of 0.5, calculated by applying the known inventory of these radionuclides in the Chernobyl reactor to the equation for the differential radioactive decay.

    Changes of genetic structures due to viability selection are likely to occur in populations exposed to rapidly and extremely changing environmental conditions after catastrophic events. However, very little is known about the extent of selective responses and in particular the proportion of the genome involved in putatively adaptive reactions for non-model plants. We used amplified fragment length polymorphisms (AFLPs) in order to investigate genetic differences between pine (Pinus sylvestris) trees which were partially exposed to extreme environmental conditions. Genetic variation patterns of pines exposed to high radiation in the Chernobyl exclusion zone with or without phenotypic stress symptoms were compared to control trees with a similar origin. Six percent of the investigated loci (15 of 222 loci) were identified as candidates for selective responses. Moderate differentiation was observed between groups of trees showing either weak or strong phenotypic responses to high radiation levels. - Highlights: > Genetic variation patterns of pines exposed to high radiation were investigated. > Pines with or without phenotypic stress symptoms were compared to control trees. > AFLP markers were used to reveal evidences of selection processes. > 15 of 222 loci are identified as candidates for selective responses. > Moderate differentiation is observed between irradiated and control trees. - Genetic responses to the exposure of trees to radiation in the Chernobyl zone may involve adaptive changes at a comparatively large part of the genome.

    The association of radiocaesium with particle size fractions separated by sieving and settling from soils sampled eight years after the Chernobyl accident has been determined. The three size fractions were: <2 {mu}m, 2-63 {mu}m and >63 {mu}m. {sup 137}Cs in the soil samples was associated essentially with the finer size fractions, which generally showed specific activities 3-5 times higher than the bulk samples. Activity ratios of {sup 134}Cs/{sup 137}Cs in the clay-sized fractions appear to be lower with respect to the corresponding values in bulk soil samples. This result indicates that some differences still exists in the particle size distribution between {sup 137}Cs originating from nuclear weapons, which has been in the soil for decades after fallout, and {sup 137}Cs coming from the Chernobyl accident, eight years after the deposition event. This behaviour could be related to 'ageing' processes of radiocaesium in soils.

    Studies to analyze the genetic processes in natural populations of plants were started on the territory of the East-Ural Radioactive Trace (EURT) in 1962 and in the zone of the Chernobyl accident in May 1986. The main directions of the genetic studies in both radioactive areas were similar: 1) study of the mutation process intensity depending on the dose and dose rate and analysis of dose-effect relationships for different genetic changes (point mutations, chromosome aberrations in mitosis and meiosis) in irradiated plant populations; 2) study of the mutation process dynamics in generations of chronically (prolongly) irradiated populations of plants; 3) analysis of microevolutionary processes in irradiated plant populations. The report presents an analysis of observed dose-effect relationships under the action of radiation on populations of Arabidopsis thaliana, Pinus sylvestris and a number of other plant species. Analysis of the mutation processes dynamics in 8 Arabidopsis populations growing in the zone of the Chernobyl catastrophe has demonstrated that the level of the embryo lethal mutations 10 years after the accident in the irradiated populations significantly exceeds the control level. The following phenomena observed in chronically irradiated populations have also been considered: increased radioresistance of irradiated populations (radioadaptation), the appearance of abnormal karyotypes and selective markers upon chronic irradiation. The authors call attention to the high importance of monitoring of genetic processes in irradiated plant populations for understanding of the action of radiation on human populations.

    The role of expert witnesses in medical malpractice litigation is often misunderstood. Much maligned, the expert has been the subject of castigation by a range of people, from his professional colleagues to the jurists who preside over his testimony. From an academic perspective, the expert witness is a necessary evil, and his denigration is his own doing; for the expert is a neutral character who creates his own professional persona. This purpose of this article is to serve as a primer for those interested in understanding the role that the expert is supposed to play in litigation, and the factors surrounding his activities.

    2014-08-01

    Sweden received about 5 % of the total release of (137)Cs from the Chernobyl nuclear power plant accident in 1986. The distribution of the fallout mainly affected northern Sweden, where some parts of the population could have received an estimated annual effective dose of 1-2 mSv per year. It is disputed whether an increased incidence of cancer can be detected in epidemiological studies after the Chernobyl nuclear power plant accident outside the former Union of Soviet Socialist Republics. In the present paper, a possible exposure-response pattern between deposition of (137)Cs and cancer incidence after the Chernobyl nuclear power plant accident was investigated in the nine northernmost counties of Sweden (2.2 million inhabitants in 1986). The activity of (137)Cs from the fallout maps at 1986 was used as a proxy for the received dose of ionizing radiation. Diagnoses of cancer (ICD-7 code 140-209) from 1980 to 2009 were received from the Swedish Cancer Registry (273,222 cases). Age-adjusted incidence rate ratios, stratified by gender, were calculated with Poisson regression in two closed cohorts of the population in the nine counties 1980 and 1986, respectively. The follow-up periods were 1980-1985 and 1986-2009, respectively. The average surface-weighted deposition of (137)Cs at three geographical levels; county (n = 9), municipality (n = 95) and parish level (n = 612) was applied for the two cohorts to study the pre- and the post-Chernobyl periods separately. To analyze time trends, the age-standardized total cancer incidence was calculated for the general Swedish population and the population in the nine counties. Joinpoint regression was used to compare the average annual percent change in the general population and the study population within each gender. No obvious exposure-response pattern was seen in the age-adjusted total cancer incidence rate ratios. A spurious association between fallout and cancer incidence was present, where areas with the

  3. Self-Governance on Trial: A Public Sphere Analysis of News Website Forum Comments

    Directory of Open Access Journals (Sweden)

    J. David Wolfgang

    2016-04-01

    Full Text Available The online public sphere offers society an opportunity to pursue self-governance through rational-critical discourse of public issues. However, testing the effectiveness of the sphere involves studying the structure of the online forum (e.g. whether the forum allows for pseudonymous comments or not and the quality of the content in the forum. This research studied online news forums on the topics of gun control and civil unions in Colorado to see what barriers to participating in the forum might exist in the structure of the forum and then what types of content was produced in the forum. The research showed that a forum allowing commenters to use a pseudonym led to comments with more exchange and critique of reasoned normative positions and use of supporting facts. However, neither the pseudonymous forum nor the identified forum had stronger levels of commitment to constructive dialogue in the forum. Also, commenters showed no reflexivity in their comments, meaning that participants were not assessing their own positions or changing their perspectives based on the arguments of others. While this shows that reducing barriers to accessing the forum helps to produce a public sphere environment, there is still work to be done in improving the level of constructive dialogue and stimulating negotiation and consensus building.

    In June 2006 Eawag moved into its new headquarters, Forum Chriesbach. The building's external appearance is striking owing to the 1232 blue glass panels which clad the compact 6-storey rectangular structure. Eawag Forum Chriesbach houses 150 workplaces, a staff cafeteria, meeting and seminar rooms as well as the library of Eawag and Empa. It is an exemplary illustration of 'sustainable' construction design and is one of the best known buildings in Switzerland. It has been awarded several prizes and described in numerous national and international publications. The building is modern, functional, aesthetic, and uses a unique array of sources for heating, including the sun as well as waste heat from light sources, electric appliances and people. Cooling requirements are very low. Only electricity requirements and the embedded energy of construction materials are of significance. Approximately one third of the electricity required, namely 70 MWh/a, is produced by photovoltaic panels on the roof, and the rest is purchased as renewable electricity from the utilities under the label 'nature-made star'. During a two-year optimization period the building's control system was adjusted and know-how was transferred from planners and builders to owners and facility managers. From autumn 2007 Eawag, Empa and 3-Plan Haustechnik AG carried out temperature and energy measurements to determine the extent to which original planning assumptions and simulation forecasts corresponded to actual experience. Computer simulations with TRNSYS have revealed the relative contribution of individual building components to the overall energy balance and their sensitivity to external parameters. Temperatures during hot summer days have remained in comfortable ranges below 26 {sup o}C and have usually ranged between 20 and 23 {sup o}C in winter. Although heating and electricity requirements have exceeded predicted levels, at 5.7 kWh/m{sup 2} weighted energy reference

  16. Forum: What Has Actually Changed in Physics Departments in the Situation for Women, Graduate Students and Other People?

    Science.gov (United States)

    Mulvey, Patrick; Ivie, Rachel; Campbell, David; Murnane, Margaret; Kirby, Kate; Catlla, Anne

    2006-03-01

    The decade of the 90's was a period of intense scrutiny of climate issues in physics departments, e.g. the status of women, the job situation for new Ph.D.'s and postdocs, and the preparation of physicists for careers inside and outside of physics. There were many conference sessions on these topics, and both APS members and leadership instigated important efforts to focus on specific areas. These efforts included the program of visiting committees to departments to examine the situation for women by the Committee on the Status of Women in Physics, the AIP's various studies of a statistical nature, and the creation by the APS of a Committee on Careers and the Forum on Graduate Student Affairs, as well as the recent APS-AAPT task force on graduate education. This forum patterned after similar sessions 10 years ago - will examine how physics departments have changed as a result of such efforts. It will begin with short (12-minute) talks by a panel of experts to describe what has happened in key areas. The greater part of the session will be a period of observations, questions, and discussion from the audience and the panel together. The purpose is to have an interchange on these interrelated topics from which we can all learn. THE TOPICS TO BE INTRODUCED IN THE SHORT TALKS AT THE BEGINNING OF THE SESSION ARE: 1) changes in graduate enrollment, composition, and subsequent jobs (Patrick Mulvey); 2) women in physics and astronomy departments 2005 (Rachel Ivie); 3) changes in graduate curricula and environment (David Campbell); 4) CSWP site visits to physics departments what’s been accomplished and learned (Margaret Murnane); 5) survey of ethical issues in physics departments and the physics profession: results and reactions (Kate Kirby); and (6) physics departments from the point of view of younger physicists (Anne Catlla). The bulk of the session will be a public forum, on these and related issues, among the audience and the panel.

    2016-08-01

    The paper presents an analysis of the incidence of cerebrovascular diseases (CeVD) in the cohort of Russian workers involved in recovery tasks after the Chernobyl accident. The studied cohort consists of 53,772 recovery operation workers (liquidators) who arrived in the zone of the Chernobyl accident within the first year after this accident (26 April 1986-26 April 1987). The mean external whole body dose in the cohort was 0.161 Gy, while individual doses varied from 0.0001 Gy to 1.42 Gy. During the follow-up period 1986-2012, a total of 23,264 cases of CeVD were diagnosed as a result of annual health examinations. A Poisson regression model was applied for estimation of radiation risks and for an assessment of other risk factors of CeVD. The following factors were considered as risk factors for CeVD: the dose, duration of the liquidators' work in the Chernobyl zone, and the concomitant diseases (hypertension, ischemic heart disease, atherosclerosis, and diabetes). The baseline incidence of CeVD is statistically significantly (p < 0.001) associated with all studied concomitant diseases. The incidence of CeVD has revealed a statistically significant dose response with the lack of a latent period and with the average ERR/Gy = 0.45, 95% CI: (0.28, 0.62), p < 0.001. Radiation risks of CeVD statistically significantly (p = 0.03) varied with the duration of liquidators' stay in the Chernobyl zone; for those who stayed in the Chernobyl zone less than 6 wk, ERR/Gy = 0.64, 95% CI = (0.38; 0.93), p < 0.001. Among studied concomitant diseases, diabetes mellitus statistically significantly (p = 0.002) increases the radiation risk of CeVD: for liquidators with diagnosed diabetes, ERR/Gy = 1.29.

  18. Starship Asterisk: APOD and General Astronomy Discussion Forum

    Science.gov (United States)

    Nemiroff, Robert J.

    2011-01-01

    A main discussion venue for the popular Astronomy Picture of the Day (APOD) website has been recently redesigned and upgraded. The online bulletin board is directly linked from the bottom of recent APODs served from http://apod.nasa.gov/ . Formerly known as "The Asterisk," the site's new design is called "Starship Asterisk" and now declares its forums to be places on a starship, with the current APOD considered as appearing on the main view screen on the Bridge. A central "mission" of Starship Asterisk is to support APOD in various ways. Toward this end, the Bridge forum exists primarily for the (archived) discussion of that day's APOD, the Observation Deck forum facilitates APOD image submissions, and the Library creates a forum where no student question about astronomy is considered to be too easy or too hard. Additionally, Starship Asterisk now includes an astronomy news-oriented links forum titled the Communications Center, a citizen science-oriented links collection called the Science Labs, and classrooms including a free online, textbook-free Astro 101 course, taught by the author, complete with video lectures and powerpoint slides. Typically, over 1,000 astronomy enthusiasts will browse Starship Asterisk on any given day. Although the vast majority of readers prefer to browse anonymously, the site has now garnered over 60,000 posts. A small but dedicated group of volunteer "officers" administer the bulletin board, answer questions about astronomy from curious APOD readers, and openly discuss various astronomy topics, frequently with intended humor. Perhaps surprisingly, the majority of volunteer officers tend NOT to be professional astronomers, but typically quite knowledgeable retirees exercising a lifelong interest in astronomy.

    Full Text Available We ran an experiment with users of Internet forums. In a dictator game, we find that the level of altruism is positively related to the activity in the forum. In a public good game, there is no relation between cooperation in the game and contribution to the content of the forum. Subjects are not more altruistic with partners from the same forum but do cooperate more with them. These results suggest that the public good provided in Internet forums is mainly provided by a group of unconditional altruistic users, and that the sense of belonging supports the cooperation in that provision.

    Full Text Available Delegates from around the world attended the sixth annual meeting of the European CME Forum in London between 14 and 15 November 2013. The participants discussed best practices in continuing medical education and continuing professional development (CME–CPD delivery, reviewed CME provision by various medical specialist societies, and viewed examples of e-CME educational activities in CME–CPD. The details of a new code for disclosure by European pharmaceutical companies were unveiled, and the implications were discussed with expert panels comparing the CME landscape in the United States with that in Europe. Accreditation systems were compared, and a number of informal sessions allowed the delegates to consider issues relevant to physician learners, transparency and accountability in CME planning and implementation, and opportunities for collaboration.

    During traditional consensus conferences, organizers control the formal information available to participants-by compiling structured background materials and recruiting expert panelists. Less formally, however, participants are encouraged to bring their own experiences into the deliberations, and in doing so, they often seek outside information. We explore this heretofore understudied phenomenon of information seeking during a deliberative event: the U.S. National Citizens' Technology Forum (2008), which addressed the convergence of nanotechnology, biotechnology, information technology, and cognitive science on the potential development of human-enhancement technologies. Through interviews with participants and observation of in-person and online deliberations, we identify outside information-seeking strategies and motivations. Our study demonstrates that conceptualizing models of deliberation as standalone settings of communication exchange ignores the reality of the complex information environment from which deliberative participants draw when making sense of technical issues. Future citizen deliberations must incorporate outside information seeking in the design of the exercises.

    Full Text Available Some remarks on the problem of knowledge representation and processing, as recognized in connection with the use of computers in the scientific research work, emphasizes the relevance of these problems for the studies on both the theory of languages and the expert system. A consideration of the common traits in the recent history of these studies, with reference to the use of computers on texts in natural language motivates the introduction of set theoretic and algebraic methods, suitable for applications in the analysis and in the automatic treatment of languages, based on the concept of model sets and on relational structures suggested from the connections between syntax and semantics evidenced in some example of sub-languages corresponding to theories of different classes of physical phenomena. Some details of these methods are evidenced, which have already successfully used or whose applications appears suggestive of interesting development.

    In radioecology, the need to understand the long-term ecological effects of radioactive contamination has been emphasised. This requires that the health of field populations is evaluated and linked to an accurate estimate of received radiological dose. The aim of the present study was to assess the effects of current radioactive contamination on nematode assemblages at sites affected by the fallout from the Chernobyl accident. First, we estimated the total dose rates (TDRs) absorbed by nematodes, from measured current soil activity concentrations, Dose Conversion Coefficients (DCCs, calculated using EDEN software) and soil-to-biota concentration ratios (from the ERICA tool database). The impact of current TDRs on nematode assemblages was then evaluated. Nematodes were collected in spring 2011 from 18 forest sites in the Chernobyl Exclusion Zone (CEZ) with external gamma dose rates, measured using radiophotoluminescent dosimeters, varying from 0.2 to 22 μGy h{sup −1}. These values were one order of magnitude below the TDRs. A majority of bacterial-, plant-, and fungal-feeding nematodes and very few of the disturbance sensitive families were identified. No statistically significant association was observed between TDR values and nematode total abundance or the Shannon diversity index (H′). The Nematode Channel Ratio (which defines the relative abundance of bacterial- versus fungal-feeding nematodes) decreased significantly with increasing TDR, suggesting that radioactive contamination may influence nematode assemblages either directly or indirectly by modifying their food resources. A greater Maturity Index (MI), usually characterising better soil quality, was associated with higher pH and TDR values. These results suggest that in the CEZ, nematode assemblages from the forest sites were slightly impacted by chronic exposure at a predicted TDR of 200 μGy h{sup −1}. This may be imputable to a dominant proportion of pollutant resistant nematodes in all sites

    Littoral (lake shore) macroinvertebrate communities were studied in eight natural lakes affected by fallout from the Chernobyl accident. The lakes spanned a range in {sup 137}Cs contamination from 100 to 15500 kBq m{sup -2} and estimated external dose rates ranged from 0.13 to 30.7 {mu}Gy h{sup -1}. General linear models were used to assess whether abundance of individuals, taxon richness, Berger-Parker dominance and Shannon-Wiener diversity varied across the lakes. Step-wise multiple regressions were used to relate variation in total abundance, taxon richness, Berger-Parker dominance, Shannon-Wiener diversity, taxon richness within major groups of macroinvertebrates and abundance of the more common individual taxa to the measured environmental characteristics (conductivity, pH, total hardness and phosphate; lake area, lake maximum depth and total external dose) of the lakes. No evidence was found in this study that the ecological status of lake communities has been influenced by radioactive contamination from the Chernobyl accident. Indeed, the most contaminated lake, Glubokoye, contained the highest richness of aquatic invertebrates. Taxon richness in the eight study lakes varied from 22 (Svyatskoe no. 7) to 42 (Glubokoye) which spans a range typical for uncontaminated lakes in the region. Since {sup 90}Sr is readily-absorbed by Mollusca, estimated dose rates to this group exceeded those for other invertebrate groups in two lakes (Perstok and Glubokoye). However this study found no association between mollusc diversity or abundance of individual snail species and variation between lakes in the external radiation dose. Indeed Glubokoye, the lake most contaminated by {sup 90}Sr, had the highest richness of freshwater snails per sample (an average of 8.9 taxa per sample). - Highlights: > We studied the effect of radiation on macroinvertebrates in Chernobyl affected lakes. > Abundance, taxon richness, Berger-Parker dominance, Shannon-Wiener diversity evaluated. > No

  8. The diagnosis of microcytic anemia by a rule-based expert system using VP-Expert.

    We describe our experience in creating a rule-based expert system for the interpretation of microcytic anemia using the expert system development tool, VP-Expert, running on an IBM personal computer. VP-Expert processes data (complete blood cell count results, age, and sex) according to a set of user-written logic rules (our program) to reach conclusions as to the following causes of microcytic anemia: alpha- and beta-thalassemia trait, iron deficiency, and anemia of chronic disease. Our expert system was tested using previously interpreted complete blood cell count data. In most instances, there was good agreement between the expert system and its pathologist-author, but many discrepancies were found in the interpretation of anemia of chronic disease. We conclude that VP-Expert has a useful level of power and flexibility, yet is simple enough that individuals with modest programming experience can create their own expert systems. Limitations of such expert systems are discussed.

    Full Text Available In an overview and analytical study of the epidemiological data on the frequency of RET/РТС gene rearrangements in sporadic and radiogenic (patients after radiotherapy, residents of contaminated after the Chernobyl disaster areas, victims after the atomic bombings, etc. carcinomas of the thyroid gland were examined. In general, the observed epidemiological laws were confirmed in radiobiology experiments by irradiation of different cultures of thyroid cells and ex vivo with the exception of Chernobyl cohorts. Induction of RET/РТС gene rearrangements by 131l exposure in children carcinomas of Chernobyl residents in mice did not observe too. It is concluded that the situation with the frequency of RET/РТС rearrangements in thyroid carcinoma in Chernobyl cohorts once again confirms the multifactorial nature of the induction and development of these tumors with a contribution of radiation and non-radiation factors (iodine deficiency and different stresses.

    Liver-specific MRI is a fast-growing field, with technological and protocol advancements providing more robust imaging and allowing a greater depth of information per examination. This article reports the evidence for, and expert thinking on, current challenges in liver-specific MRI, as discussed at the 7th International Forum for Liver MRI, which was held in Shanghai, China, in October 2013. Topics discussed included the role of gadoxetic acid-enhanced MRI in the differentiation of focal nodular hyperplasia from hepatocellular adenoma and small hepatocellular carcinoma (HCC) from small intrahepatic cholangiocarcinoma (in patients with chronic liver disease), the differentiation of low-grade dysplastic nodule (DN) from pre-malignant high-grade DN and early HCC, and treatment planning and assessment of treatment response for patients with HCC and colorectal liver metastasis. Optimization of the gadoxetic acid-enhanced MRI protocol to gain robust arterial and hepatobiliary phase images was also discussed. Gadoxetic acid-enhanced MRI demonstrates added value for the detection and characterization of focal liver lesions and shows promise in a number of new indications, including regional liver functional assessment and patient monitoring after therapy; however, more data are needed in some areas, and further developments are needed to translate cutting-edge techniques into clinical practice.

    Full Text Available The paper presents a new approach to the research of individual, collective and historical memory — through the prism of environmental disasters. Although they lead not only to physical but also to mental trauma in modern scientific discourse this aspect has not become a subject of special studies. In the example of Chernobyl disaster traumatic experience of 50 residents of Kiev, who received indirect effects of the accident, is analyzed. It is shown the formation a stable distrust of the authorities of the USSR, which is transferred to the present and entails a negative assessment of the environmental policy of independent Ukraine. Factors, which cause such situation and its relationship with the views of respondents on their future, are established. The conclusion of the feasibility of using the questionnaire method for determining the main trends traumatic impact of environmental disasters on individual memory is done. Directions for further in-depth research in this area are proposed.

    The Chernobyl accident in 1986 has been and still is the subject of great interest. Journalistic reports often contain exaggerations and undocumented statements and much uncertainty about the true consequences of the accident prevails in the population. This article reviews the current literature with the focus on reports from official commissions and documentation in the form of controlled studies. The fatal deterministic consequences comprise about 30 victims. The most important outcome is a marked increase in the incidence of thyroid cancer in children and adolescents in the most heavily contaminated area. Furthermore, pronounced psychosocial problems are dominant in the population of the contaminated area. Other significant and documented health consequences are not seen. (au)

    2003-07-01

    A detailed investigation of 3 populations of Oligochaete species (Dero obtusa, Nais pseudobtusa and Nais pardalis) has been carried out in contaminated lake of the close-in Chernobyl zone and in a control lake. Hydrochemical indices and concentrations of heavy metals, chloro-organi compounds and {sup 90}Sr in bottom sediments have been measured. Absorbed doses were calculated on the basis of the results of radiochemical analysis an assessed directly with thermoluminescent dosimeters (TLD). Stimulation of paratomous division (asexual reproduction) was found in one species of worm (D. obtusa), and activation of sexual reproduction in the two other specie studied. An increase in the amount of cytogenetic damage in the somatic cells of worms from the contaminated lake was found and an attempt was made to assess the relative contributions of radiation and chemical exposure on the basis of analyses of inter-cellular aberration distributions and the types of chromosome aberrations observed in the cells.

    1992-03-01

    Increased atmospheric radioactivity after the accident in Chernobyl was first detected on air filters. Measurements were begun in Valencia on May 2, 1986, with the maximum activity being observed around May 3-4, 1986. As a consequence of this accident, annual campaigns of measurements on migrating birds (several species of aquatic birds and song-thrushes) were started. The data corresponding to the campaign immediately after the accident (1986/87) show a generalized contamination (approximately 50% of the measured specimens). Significant levels of 134Cs, 137Cs and 110Agm were found. It is important to note that 110Agm is only present in Aythya ferina. In the successive campaigns in 1988/89 and 1989/91 few samples were found to be contaminated and only 137Cs was identified. Strontium-90 was measured and identified in some specimens, mainly in their bones.

  20. Chernobyl-derived radiocesium in heather honey and its dependence on deposition patterns.

    Fisk, S; Sanderson, D C

    1999-10-01

    Gamma-ray spectra were measured from Scottish heather honey samples gathered from hive locations with associated airborne gamma-ray survey data. The honeys all contained radiocesium, with activity concentrations ranging from 43-680 Bq kg(-1) 137Cs, and 134Cs/137Cs ratios consistent with Chernobyl deposition. Activity concentrations in honey were highly correlated with ground deposition within 2.5 km of the hive location over two successive years. Both isotope ratios and the quantitative relationships between environmental and food levels suggest that weapons testing fallout is significantly less available than recent deposition. The implications for design of future monitoring programs and radiological consequences are discussed. The whole-body retention of 137Cs in honey ingested by a volunteer was consistent with the ICRP's metabolic model for cesium.
