Sample records for agencies mark chernobyl

  1. UN agencies mark Chernobyl anniversary with launch of US$2.5-million project

    On the 24th of April 2009 four United Nations agencies marked the 23rd anniversary of the Chernobyl nuclear accident by launching a $2.5 million programme designed to meet the priority information needs of affected communities in Belarus, the Russian Federation, and Ukraine. Funded by the UN Trust Fund for Human Security, this three-year initiative aims to translate the latest scientific information on the consequences of the accident into sound practical advice for residents of the affected territories. The project is a joint effort by the International Atomic Energy Agency (IAEA), the United Nations Development Programme (UNDP), the United Nations Children's Fund (UNICEF), and the World Health Organization (WHO)

  2. Chernobyl

    Due to southeasterly wind and rainfall during the critical days after the Chernobyl accident, Norway got a substantial part of the cesium isotopes released. The radioactive fallout followed closely the rainfall and was mainly concentrated to some thin populated areas in the central parts of the country. This report summerize the results from a post-Chernobyl research program on aquatic and terrestrial ecosystems in contaminated areas. Pathways, processes and factors determining the Cs-137 concentration in soil, plant, water, fish and wild animal were investigated. 84 refs., 40 figs., 20 tabs

  3. Chernobyl

    The Chernobyl reactor accident provoked a wave of public discussion about the peaceful uses of nuclear energy, and particularly so in the Federal Republic of Germany. The article in hand discusses some consequences as can be assessed so far, although information on the causes and the course of the accident still is very incomplete. From the information available so far, the possible sequence of events is described. The safety engineering and design of Federal German reactor types is compared with the reactor type installed at Chernobyl, with the result that the Soviet type never would have been licensed in the FRG. The fallout, i.e. the resulting radiation exposure of the population, is expected to remain within the limits of the natural radioactivity; the political effects and possible consequences with regard to further commitments for the advancement of the fast breeder reactor line and the reprocessing of spent fuel are discussed.

  4. Chernobyl

    The reactor accident in Chernobyl also had a memorable 1986 Spring for the region of Lake Constance. Salad had to be ploughed up in the vegetable fields, the feeding of cows with fresh grass was forbidden, and becquerel values played a decisive role in food purchases. Along with the measurement of radioactivity in rainwater, the authors began to take food and soil samples; hundreds of samples were tested in the laboratories of the University of Constance. They provided, in cooperation with public authorities, for the protection of the population against radiation, and explained, in numerous lectures, the significance of this incident to everyday life. Besides, they recorded recent scientific findings about the behaviour of radioactive substances in the environment. The book gives a summary of the findings. It also includes, besides a description of the events of May 1986 at Lake Constance, a presentation of the results of scientific investigations into Chernobyl's radioactivity. This is thus the first detailed account of the diverse effects of the reactor accident with respect to one particular region which, though more than 1500 km away, was surprisingly seriously affected, and which, owing to its special features - Lake Constance is Europe's most important drinking water reservoir -, is particularly endangered, in case of radioactive release.

  5. Chernobyl

    This book brings together a comprehensive history of the first 18 months of the accident at Chernobyl and the complete pictorial record of the disaster, including many photographs never seen in the West. It also gives a unique record of subsequent events in the USSR involving the evacuation and re-housing of a population of 135,000, the building of the 400,000 tonne concrete sarcophagus over the damaged reactor and the decontamination of the environment which may take years to complete. The human dimension of radiation injuries is recreated in the cast histories and hospital photographs of the firemen who brought the blaze under control. The problems of contamination of the food chain for various countries is included, and recommendations for safe levels of activity in milk are described

  10. Chernobyl - Ten years after

    A decade later, in April 1996, more than 800 experts from 71 countries and 20 organizations, observed by over 200 journalists, met to review the Chernobyl accident's actual and possible future consequences, and to put these into proper perspective. They came together at the international conference on One Decade after Chernobyl: Summing up the Consequences of the Accident, held at the Austria Center in Vienna. The Chernobyl Conference was a model of international co-operation: six organizations of the UN family, including the IAEA, and two important regional agencies were involved in its organization

  11. Chernobyl and the media

    The way the media reported the Chernobyl nuclear reactor accident was discussed at a day seminar in Birmingham in July. Contributors were from the Forsmark nuclear power station in Sweden where the disaster was first noticed, the International Atomic Energy Agency, the Russian film industry, French TV and SCRAM. Personal experiences and opinions of Chernobyl and the media were discussed. The approach in West Germany, France, Finland and the United Kingdom is compared. (UK)

  12. The enduring lessons of Chernobyl

    The major impacts of the Chernobyl accident fall into three categories: the physical impacts, in terms of health and environmental effects; the psycho-social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide. The physical impacts mark Chernobyl as the site of the most serious nuclear accident in history. The explosions that destroyed the Unit 4 reactor core released a cloud of radionuclides that contaminated large areas of Belarus, Russia and Ukraine. Hundreds of thousands of workers participated in efforts to mitigate the consequences of the accident, and many of these individuals were exposed to substantial radiation doses. The psycho-social impacts were also devastating. Over 100 000 people were evacuated immediately after the accident, and the total number of evacuees from severely contaminated areas eventually reached 350 000 people. While these resettlements helped to reduce the collective dose of radiation, it was deeply traumatic for those involved. The third impact I mentioned is the enormous influence of the Chernobyl accident on the nuclear industry. A decade earlier, the accident at Three Mile Island had already cast doubt on the ability of nuclear power plant operators to prevent severe accidents. Chernobyl had far greater impact; the accident emblazoned itself on public consciousness as proof positive that nuclear safety was an oxymoron. Some countries decided to reduce or terminate further construction of nuclear facilities, and the expansion of nuclear capacity came to a near standstill. It has taken nearly two decades of strong safety performance to repair the industry's reputation. From the time of the accident, the IAEA has been continuously involved in technical assistance and research projects to mitigate the environmental and health consequences in affected areas. Since 1990, more than $15 million has been disbursed through the IAEA technical cooperation programme on a broad range of these

  13. Byelorussia's Chernobyl legacy

    Following the Chernobyl nuclear accident on 26 April 1986 radioactive fall-out was widely distributed over the eastern territories of the Soviet Union and over Europe. While the effects in Europe have been well documented and have received widespread media attention, less is known about the effects within the Soviet Union. The general picture that has been painted is that while the accident was serious, it wasn't that bad and the resulting contamination is something that can be lived with. In reality many people are living in contaminated zones which would be regarded as completely unacceptable in the United Kingdom. However, the USSR Ministry of Public Health has argued that relocation is not necessary. The Ministry and other agencies including the Red Cross do not recognize the contamination as serious and feel the main side effect of Chernobyl is psychological. In Byelorussia however, 100,000 people are still living in areas of major contamination. (author)

  14. Chernobyl reactor accident

    On April 26, 1986, an explosion occurred at the newest of four operating nuclear reactors at the Chernobyl site in the USSR. The accident initiated an international technical exchange of almost unprecedented magnitude; this exchange was climaxed with a meeting at the International Atomic Energy Agency in Vienna during the week of August 25, 1986. The meeting was attended by more than 540 official representatives from 51 countries and 20 international organizations. Information gleaned from that technical exchange is presented in this report. A description of the Chernobyl reactor, which differs significantly from commercial US reactors, is presented, the accident scenario advanced by the Russian delegation is discussed, and observations that have been made concerning fission product release are described

  15. After Chernobyl

    The Chernobyl accident mobilized profound anxieties in many people, which subsequently were repressed again and played down with the aid of the known psychological mechanisms. The authors trace the anxiety, and the resistance against it, and pose the question of whether we are at all capable of learning to think along new lines. From the contents: 10 theses on Chernobyl 1986 (Anders, G.); Anxiety, apathy and new thinking (Richter, H.-E.); On the Germans' particular way of dealing with existential threats (Wirth, H.-J.); Appeasement and delusion - small and big flights from powerlessness (Leithaeuser, T.); Socio-psychological theses on the consequences of nuclear energy (Clemenz, M.); Psychological arguments in the discussion about Chernobyl (Kettner, M.); Relationship between fear and technology (Brede, K.); Inhumanity of technology (Spangenberg, N.); Psychology of nuclear addiction (Bauriedl, T.); Nature or technology - search of the wizard's apprentice for lost salvation (Bastian, T./Hilger, M.); Living under a nuclear threat - significance of existential fear experienced during childhood (Boehnke, K., et al.); Survey of, and psychoanalytical reflections on, poisoned childhood (Petri, H.); On knowing, feeling, and experience after Chernobyl (Thiel, W.); Sociopsychological aspects of the staging of politics as a state spectacle fit for the media (Fuechner, H.).

  16. Project Chernobyl

    The aim of the follow-up after the Chernobyl fallout is to obtain the best possible information about the environmental and dose commitment consequences in Sweden. The essential part of the work by the institute to improve the state of readiness is described. (G.B.)

  17. Chernobyl fantasy

    Several versions of technical reasons of Chernobyl accident, which have received a wide resonance in mass-media, and are seemed as reasonable for most public without any special education in reactor's physics, are discussed. Probable reasons of its origination are analysed, and its scientific groundlessness is shown

  18. Chernobyl, 14 years later

    This report draws an account of the consequences of Chernobyl accident 14 years after the disaster. It is made up of 8 chapters whose titles are: 1) Some figures about Chernobyl accident, 2) Chernobyl nuclear power plant, 3)Sanitary consequences of Chernobyl accident, 4) The management of contaminated lands, 5) The impact in France of Chernobyl fallout, 6) International cooperation, 7) More information about Chernobyl and 8) Glossary

  19. Chernobyl assessed (Report of NEA)

    Modern state of knowledge about Chernobyl accident effect on men's health as well as radiological and social-economic impacts for population of Belarus, Ukraine and Russian Federation is presented in the report of the Nuclear Energy Agency (NEA). Accepted estimations of absorbed radiation dose of population suggest that except the thyroid disease it is improbable that irradiation causes radiation effects among population

  20. After Chernobyl

    This report discusses a number of effects of the Chernobyl-accident on public opinion about nuclear power. The analysis is based on a comparison of a survey conducted shortly after Chernobyl and a number of measurements in the Netherlands between 1982 and 1986. The conclusions can be summarized as follows: Attitudes towards nuclear power and especially towards building new stations have become much more negative after the disaster in Chernobyl. Although a majority of the population now wants to close existing nuclear power stations, there appears strong support for continuation of nuclear research. The structure of the nuclear debate has not changed fundamentally. Supporters and opponents have kept the same demographic characteristics. The arguments which distinguish them have not changed, except that the expectation of a serious accident has an increased impact on attitudes. A majority of the population felt the information after the accident not sufficient. Since 1982 attitudes towards coal also have become more negative, mainly as a consequence of the higher visibility of effects of acid rain. (Auth.)

  1. Emergency preparedness lessons from Chernobyl

    Emergency preparedness at nuclear power plants in the U.S has been considerably enhanced since the Three Mile Island accident, The Chernobyl accident has provided valuable data that can be used to evaluate the merit of some of these enhancements and to determine the need for additional improvements, for example, the USSR intervention levels of 25 rem and 75 rem for evacuation are contrasted with U.S Environmental Protection agency protective action guides. The manner in which 135,000 persons were evacuated from the 30-km zone around Chernobyl is contrasted with typical U.S. evacuation plans. Meteorological conditions and particulate deposition patterns were studied to infer characteristics of the radioactive plume from Chernobyl. Typical plume monitoring techniques are examined in light of lessons learned by the Soviets about plume behavior. This review has indicated a need for additional improvements in utility and government emergency plans, procedures, equipment, and training

  2. Chernobyl - a Canadian technical perspective

    In this report we present the design review done to date in Canada by AECL. From the Canadian point of view it covers: 1) relevant information on the Chernobyl design and the accident, both as presented by the Soviets at the Post-Accident Review Meeting (PARM) held in Vienna from August 25-29, 1986, and as deduced from publicly available Soviet documentation; and 2) details of AECL's technical review of the CANDU PHWR (Pressurized Heavy Water Reactor) against the background of the Chernobyl accident, and implications of the Chernobyl accident. Reviews of operational aspects are underway by the Canadian electrical utilities and a review by the Canadian regulatory agency (the Atomic Energy Control Board) is near completion

  3. Chernobyl, 12 years later

    This report draws an account of the consequences of Chernobyl accident 12 years after the disaster. It is made up of 7 chapters whose titles are: 1) Some figures about Chernobyl accident, 2) The Chernobyl nuclear power plant, 3)Sanitary consequences of Chernobyl accident, 4) The management of contaminated lands, 5) The impact in France of Chernobyl fallout, 6) The Franco-German cooperation, and 7) Glossary

    2005-01-01

    For many years, Nagasaki University, particularly the Atomic Bomb Disease Institute, has been engaged in research regarding the late health effects of radiation exposure in Nagasaki atomic bomb survivors. Since 1991, we have participated in several Chernobyl projects including the Chernobyl Sasakawa Medical Cooperation Project which demonstrated a marked increase in the incidence of childhood thyroid cancer around Chernobyl, especially in the Gomel region, Belarus. Furthermore, we have perfor...

  5. The Chernobyl disaster

    The Chernobyl disaster is examined in chronological order from the experiment that led to the explosions, to the firefighting efforts, the release of radioactivity, its fallout, the evacuations from the contaminated zone and the long-term medical, ecological, economic and political repercussions. The sources of information are nearly all Soviet - the Ukranian and Russian press, Moscow and Kiev radio broadcasts, Soviet television documentaries and the report of the Soviet government commission to the International Atomic Energy Agency in August 1986. Reports by the United Kingdom Atomic Energy Authority, the Central Electricity Generating Board and the International Atomic Energy Agency have also been used. The latter chapters look at who was to blame for the accident, what impact the accident has had on Soviet society and why the Soviet government continues to expand its nuclear power programme. (author)

  6. Chernobyl accident

    The examination of the radioelements in macromicetae taken in the area of Como's Groane and in other areas near Lakes of Como and Maggiore and a few samples in Pine' di Trento are reported. A number of samples has been collected and analyzed at Joint Research Center, Ispra. A sampling of many pieces has been picked up by the Circolo Micologico Plinio il Vecchio and by the Unita' Sanitarie of Como and Varese. The various samples are subdivided for specie and the denomination for each one of them is given. The foundamental sampling is dated atumn 1986, a second sampling is made in autumn 1987. Gamma spectrometry has revealed the presence of many radiosotopes due to the Chernobyl fall-out. as Cs137, Cs134 and Ag110 (metastable); levels of Potassium 40, a natural radioactive element have been also measured. A discussion of results is presented and the comparison among data of the 1986 season and the 1987 one

  7. Chernobyl 2015

    After having recalled the Chernobyl accident process and consequences for the power station buildings, and also the emergency interventions to cover the reactor and avoid that the molten core reaches underground waters, the author proposes a brief overview of the consequences at the international level in the field of nuclear safety with the emergence of a culture of safety which has been applied in other industrial sectors, with the improvement of the quality of transmitted information, and with the lessons learned about the efficiency of early ingestion of iodine pills. The author evokes the construction of a containment arch to dismantle the whole installation, comments the various results published on health consequences and gives some explanations about their discrepancy

  8. The international Chernobyl project

    This article summarizes the official report of the International Advisory Committee at the conference of the International Chernobyl Project held in Vienna, May 1991. More details will be found in the actual report, ''The International Chernobyl Project: An Overview'' (INI22:066284/5). Measurements and assessments carried out under the project provided general corroboration of the levels of surface cesium-137 contamination reported in the official maps. The project also concluded that the official procedures for estimating radiation doses to the population were scientifically sound, although they generally resulted in overestimates of two- to threefold. The project could find no marked increase in the incidence of leukemia or cancer, but reported absorbed thyroid doses in children might lead to a statistically detectable rise in the incidence of thyroid tumors. Significant non-radiation-related health disorders were found, and the accident had substantial psychological consequences in terms of anxiety and stress. The project concluded that the protective measures taken were too extreme, and that population relocation and foodstuff restrictions should have been less extensive

  9. The enduring lessons of Chernobyl. International conference of the Chernobyl Forum, 6 September 2005, Vienna, Austria

    The April 1986 accident at the Chernobyl nuclear power plant remains a defining moment in the history of nuclear energy. The lessons of this tragedy are interwoven with a recurrent theme: namely, the importance of international cooperation. With its recently released document - entitled 'Chernobyl's Legacy' - the Chernobyl Forum has solidly reinforced that theme. The major impacts of Chernobyl fall into three categories: the physical impacts, in terms of health and environmental effects; the psychological and social impacts on the affected populations; and the influence of the accident on the nuclear industry worldwide. The physical impacts mark Chernobyl as the site of the most serious nuclear accident in history. The explosions that destroyed the Unit 4 reactor core released a cloud of radionuclides that contaminated large areas of Europe and, in particular, Belarus, the Russian Federation and Ukraine. Hundreds of thousands of people were exposed to substantial radiation doses, including workers from all three of these countries who participated in efforts to mitigate the consequences of the accident. The definitive numbers compiled in the Chernobyl Forum report are sobering: the 50 emergency rescue workers who died from acute radiation syndrome and related illnesses; the 4000 children and adolescents who contracted thyroid cancer - 9 of whom also died; and the hundreds of thousands of hectares of cropland, forests, rivers and urban centres that were contaminated by environmental fallout. But as severe as these impacts were, the situation was made even worse by conflicting information and vast exaggerations - in press coverage and pseudo-scientific accounts of the accident - reporting, for example, fatalities in the tens or hundreds of thousands. The psychological and social impacts were also devastating. Over 100 000 people were immediately evacuated, and the total number of evacuees from contaminated areas eventually reached 350 000. While some of these

  10. Impressions of Chernobyl

    Three years on from the nuclear power plant accident, an inaugural meeting of the Wano (World Association of Nuclear Operators) discusses impressions of the Chernobyl incident on a technical tour through the Chernobyl exclusion zone. (author)

  11. Chernobyl, 17 after

    This information document takes stock on the Chernobyl accident effects, 17 years after the reactor accident. The domains concerned are: the Chernobyl power plant, the sanitary consequences of the accident in the most exposed countries, the Chernobyl environment and the polluted regions management, the Chernobyl accident consequences in France; Some data and technical sheets on the RBMK reactors and the international cooperation are also provided. (A.L.B.)

  12. Chernobyl revisited

    Observations made on a visit to the Chernobyl area in July 1990 are reported. Although the main purpose of the visit was to try out thermoluminescence techniques on materials exposed to radiation during the accident, the observations reported here are of a more general nature covering the variations in dose rate and contamination of surfaces within the 30 km exclusion zone and in the deserted tow of Pripyat, and plant, animal and bird life. The most ubiquitous contamination in Pripyat is caesium, which has penetrated all porous surfaces and would probably be very difficult to remove from brick structures if rehabitation were ever contemplated. Recorded dose-rates varied considerably on and in different parts of buildings. Radiation measurements of external surfaces were typically in the range 1-10 μSv/h and an order of magnitude less within buildings. Grass verges were particularly badly contaminated; measurements up to 110 μSv/h were noted in the most polluted area of Pripyat. Ecologically, the area seems to have benefited from having been allowed to return to nature. Many birds and a wide variety of plants and trees were flourishing; some older pine trees showed evidence of damage, however. The only insects observed were peacock butterflies. (Author)

  13. Chernobyl - Could it happen here? [videorecording

    Following the accident at the Soviet nuclear power station at Chernobyl in April 1986, the CEGB produced this video which has now been updated in the light of the information provided by the Soviets at the International Atomic Energy Agency Conference in Vienna. At this conference it was made clear that the Chernobyl accident would have been impossible in any nuclear reactor operational outside the USSR. This video explains why. It examines the main reasons for the failure of the reactor at Chernobyl and the two fundamental design flaws which resulted in the sequence of events leading up to the accident. It shows how British reactors have built-in protection to compensate for failure in any part of the system, and how the reactors are tolerant to operator error. The programme also explains the safety standards and regulations which are enforced in CEGB nuclear power stations and the rigorous training that reactor operators have to undergo

  14. The Chernobyl catastrophe: Consequences on human health

    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

  17. Assisting the Return to Normal Life in Chernobyl-Affected Regions: The International Chernobyl Research and Information Network (ICRIN)

    This article describes the International Chernobyl Research and Information Network (ICRIN) project, a programme designed to meet the priority information needs of communities in areas of Belarus, the Russian Federation and Ukraine which were affected by the 1986 nuclear accident. Its aim is to empower Chernobyl affected communities through targeted delivery of the most recent scientific information on the accident’s impacts, translated into practical advice, including recommendations on healthy lifestyles. Supported by a United Nations General Assembly resolution, the project is part of a broader effort by all United Nations agencies to help local communities return to normal life, under the United Nations Action Plan on Chernobyl to 2016.

  18. Chernobyl: a documentary story

    This account of the Chernobyl disaster of April 1986 is based on interviews with many of the participants. Realising that the Chernobyl accident was to have a massive impact on the USSR and the world, the author felt impelled to travel to the designated danger zone around the reactor, to live there and to interview firemen, first-aid workers, party and government officials and local media representatives. The result is a variety of vivid eyewitness accounts that are unprecedented in their detail and frankness. These accounts show why the author considers the Chernobyl accident to be the most important event in the Soviet Union since World War II. The book, itself a product of glasnost, reveals how the Chernobyl accident was viewed from inside the Soviet Union. (author)

  2. Radiation exposure and breast cancer: lessons from Chernobyl.

    Ogrodnik, Aleksandra; Hudon, Tyler W; Nadkarni, Prakash M; Chandawarkar, Rajiv Y

    2013-04-01

    The lessons learned from the Chernobyl disaster have become increasingly important after the second anniversary of the Fukushima, Japan nuclear accident. Historically, data from the Chernobyl reactor accident 27 years ago demonstrated a strong correlation with thyroid cancer, but data on the radiation effects of Chernobyl on breast cancer incidence have remained inconclusive. We reviewed the published literature on the effects of the Chernobyl disaster on breast cancer incidence, using Medline and Scopus from the time of the accident to December of 2010. Our findings indicate limited data and statistical flaws. Other confounding factors, such as discrepancies in data collection, make interpretation of the results from the published literature difficult. Re-analyzing the data reveals that the incidence of breast cancer in Chernobyl-disaster-exposed women could be higher than previously thought. We have learned little of the consequences of radiation exposure at Chernobyl except for its effects on thyroid cancer incidence. Marking the 27th year after the Chernobyl event, this report sheds light on a specific, crucial and understudied aspect of the results of radiation from a gruesome nuclear power plant disaster. PMID:23691737

  3. Chernobyl, 16 years later

    This document on the Chernobyl site evolution is constituted around four main questions. What about the future of the Chernobyl site, the damaged reactor and the ''sarcophagus'' constructed around the reactor? What about the sanitary consequences of the accident on the liquidators asked to blot out the radiation and the around people exposed to radiation? What about the contaminated land around the power plant and their management? Concerning the France, what were the ''radioactive cloud'' sanitary consequences? (A.L.B.)

    The collection comprises the materials of working meeting 'The Development of Technologies of the 'Ukrytie' Radioactive Waste Management', held on May 20-21, 1997 in Chernobyl. The results of research work of the experts of Ukraine and other countries directed on solving problems, concerning removal of fuel containing materials and other radioactive waste from destroyed Unit 4 of Chernobyl NPP are given. The data on waste quantities, their location and classification, strategy of waste management and some technologies are described

  5. Medical cooperative projects. From Nagasaki to Chernobyl and Semipalatinsk

    For many years, Nagasaki University, particularly the Atomic Bomb Disease Institute, has been engaged in research regarding the late health effects of radiation exposure in Nagasaki atomic bomb survivors. Since 1991, we have participated in several Chernobyl projects including the Chernobyl Sasakawa Medical Cooperation Project which demonstrated a marked increase in the incidence of childhood thyroid cancer around Chernobyl, especially in the Gomel region, Belarus. Furthermore, we have performed both fieldwork and research to clarify the late effects of radiation exposure around Semipalatinsk Nuclear Testing Site and participated in bilateral official medical assistance projects between Japan and Kazakhstan to strengthen the medical infrastructure in this area. Through these humanitarian and scientific projects, we have been collaborating closely with our counterparts in the former Union of Soviet Socialist Republics (USSR) for the past 15 years. Here, we present a brief review of our past activities and future directions of international cooperative radiation research from Nagasaki to Chernobyl and Semipalatinsk. (author)

  6. Chernobyl, 13 years after

    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. Health consequences of the Chernobyl accident;. 4. The impact of Chernobyl fallout in France

  7. Real and mythical consequences of Chernobyl accident

    This presentation describes the public Unacceptance of Nuclear Power as a consequence of Chernobyl Accident, an accident which was a severest event in the history of the nuclear industry. It was a shock for everybody, who has been involved in nuclear power programs. But nobody could expect that it was also the end romantic page in the nuclear story. The scale of the detriment was a great, and it could be compared with other big technological man-made catastrophes. But immediately after an accident mass media and news agencies started to transmit an information with a great exaggerations of the consequences of the event. In a report on the Seminar The lessons of the Chernobyl - 1' in 1996 examples of such incorrect information, were cited. Particularly, in the mass media it was declared that consequences of the accident could be compared with a results of the second world war, the number of victims were more than hundred thousand people, more than million of children have the serious health detriments. Such and other cases of the misconstruction have been called as myths. The real consequences of Chernobyl disaster have been summed on the International Conference 'One decade after Chernobyl' - 2, in April 1996. A very important result of the Chernobyl accident was a dissemination of stable unacceptance of the everything connected with 'the atom'. A mystic horror from invisible mortal radiation has been inspired in the masses. And from such public attitude the Nuclear Power Programs in many countries have changed dramatically. A new more pragmatic and more careful atomic era started with a slogan: 'Kernkraftwerk ? Nein, danke'. No doubt, a Chernobyl accident was a serious technical catastrophe in atomic industry. The scale of detriment is connected with a number of involved peoples, not with a number of real victims. In comparison with Bhopal case, earthquakes, crashes of the airplanes, floods, traffic accidents and other risky events of our life - the Chernobyl is

  8. Space Radar Image of Chernobyl

    1994-01-01

    This is an image of the Chernobyl nuclear power plant and its surroundings, centered at 51.17 north latitude and 30.15 west longitude. The image was acquired by the Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar aboard the space shuttle Endeavour on its 16th orbit on October 1, 1994. The area is located on the northern border of the Ukraine Republic and was produced by using the L-band (horizontally transmitted and received) polarization. The differences in the intensity are due to differences in vegetation cover, with brighter areas being indicative of more vegetation. These data were acquired as part of a collaboration between NASA and the National Space Agency of Ukraine in Remote Sensing and Earth Sciences. NASA has included several sites provided by the Ukrainian space agency as targets of opportunity during the second flight of SIR-C/X-SAR. The Ukrainian space agency also plans to conduct airborne surveys of these sites during the mission. The Chernobyl nuclear power plant is located toward the top of the image near the Pripyat River. The 12-kilometer (7.44-mile)-long cooling pond is easily distinguishable as an elongated dark shape in the center near the top of the image. The reactor complex is visible as the bright area to the extreme left of the cooling pond and the city of Chernobyl is the bright area just below the cooling pond next to the Pripyat River. The large dark area in the bottom right of the image is the Kiev Reservoir just north of Kiev. Also visible is the Dnieper River, which feeds into the Kiev Reservoir from the top of the image. The Soviet government evacuated 116,000 people within 30 kilometers (18.6 miles) of the Chernobyl reactor after the explosion and fire on April 26, 1986. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight

  9. Healthy living after Chernobyl?

    Our food today is endangered not only through environmental poisons and the machinations of profit-hungry manufacturers but also, after the reactor disaster of Chernobyl, by radioactive materials. There is great uncertainty amongst consumers: Whan can I still eat? How can I best protect my children from food products contaminated by radioactivity or enriched with pollutants? Does it still make sense to buy organically produced foodstuffs? Which food products are low in pollutants? With this book the authors want to counteract general helplessness and help the reader with comprehensible and sound information as well as practical tips for eating and living healthily after Chernobyl. (orig.)

  10. Chernobyl - the government reaction

    The Farmers' Union of Wales submitted this memorandum to the Agriculture Committee of the House of Commons giving its interpretation of the Government's reaction to the Chernobyl disaster. The primary aim of the paper is to provide an objective assessment of the impact of the disaster and the Government's handling of it, for future reference. The subject is dealt with under the following headings:- Chernobyl nuclear fallout in Wales, monitoring of milk and fresh vegetables, silage contamination, the North Wales Sheep Sector, soil, herbage and genetic implications, recommendations for the future. (UK)

  11. The Chernobyl catastrophe is the most terrible civil nuclear incident

    Full text: The 4th nuclear reactor of the Chernobyl NPP exploded on 26 April 1986, 20 years ago. It's the most terrible nuclear civil accident of all times. The consequences of the Chernobyl accident led to contamination of 3,1 million ha of arable land, 1,5 million ha of natural pasture land, 3,5 million ha of forests and changed the lifestyle for millions of people in Belarus, Ukraine and Russia. It is well known that the mortality in the contaminated areas (infant mortality by cancer) drastically increased. The Chernobyl catastrophe is presented , such as a sad example for humanity, a complex political international, economical, social and, particular, ecological problem according to the traditional and new studies for the development of the nucleotide contaminated territories: 1. Financing of safety of stopped working 4th nuclear reactor (security of covering system) and of work another 3 blocks at the Chernobyl NPP. Detailed control of international financial support for guarantee the safety, security of the Chernobyl NPP and sustainable development for rehabilitation of the affected zones and people. 2. It should be marked increase in medical, demographic analysis and in social, economical protection of the people in the contaminated areas. 3. Analysis and synthesis, monitoring of the long-time data results due to environmental, ecological, social and political consequences of the Chernobyl disaster. 4. Protection from the possible terrorist (extra) actions and (inter) damage or incident function of the Chernobyl plant, such as an old generation nuclear power. 5. Planned budget for future studies in the affected territories and flexibility actually realization of budget (State and International). 6. Nuclear refuse and aria/water protection in the Ukraine, Belarus and Russia contaminated zones. 7. Risk evaluation of not good function of NPPs which are situated in Russia, Ukraine and in another places (always remembering that the Chernobyl catastrophe is the

  12. Chernobyl and our health

    The health impacts in Sweden of the Chernobyl accident are discussed in this booklet. Five experts of different relevant fields (biology, radioecology, nuclear physics and psychology) give their views on probable radiation doses and health effects from these doses, contamination of food chains etc. (L.E.)

  13. Nuclear energy after Chernobyl

    This paper on fundamental questions by a representative of the Federal German Government focuses on the following subjects: Nuclear energy as a part of the energy policy of the Federal German Government, the justifiability of nuclear energy, lessons from Chernobyl, nuclear phase-out, safety concepts for the future, supply of nuclear power plants, and nuclear waste disposal. (UA)

  14. Chernobyl accident and Danmark

    The report describes the Chernobyl accident and its consequences for Denmark in particular. It was commissioned by the Secretary of State for the Environment. Volume 1 contains copies of original documents issued by Danish authorities during the first accident phase and afterwards. Evaluations, monitoring data, press releases, legislation acts etc. are included. (author)

  15. Chernobyl: The WHO helps

    This booklet addresses concerns of the populations of the areas of Belarus, Ukraine and Russia affected by the Chernobyl accident. Answers to commonly asked questions comprise the bulk of the information, but the booklet also describes the WHO's work to study and mitigate the effects on the exposed populations

  16. The Chernobyl reactor accident

    The documentation abstracted contains a complete survey of the broadcasts transmitted by the Russian wire service of the Deutsche Welle radio station between April 28 and Mai 15, 1986 on the occasion of the Chernobyl reactor accident. Access is given to extracts of the remarkable eastern and western echoes on the broadcasts of the Deutsche Welle. (HP)

  17. Wildlife in Chernobyl forests

    The article is a review of a book addressed Wormwood Forest: a natural history of Chernobyl which describes life in Europe's largest wildlife sanctuary in the region surrounding the Chernobyl station. Since the accident, the area has largely been a safe haven from hunters and farmers, allowing the wildlife to live in an undisturbed environment. Against this backdrop, the book describes in detail, a highly controversial programme that released an endangered species of horse into the zone. Lack of funding for such programmes makes it nearly impossible to administer them. The book blends reportage, popular science and encounters with the zone's few residents. The result is an account of a remarkable land, its people and animals seen through the eyes of the locals, the author and the zoologists, botanists and radiologists who travelled with her around the zone. The radiation is the book's ever-present protagonist, as the author describes in detail how it works itself through the entire food chain and environment. Along the author's journey through the affected regions of Belarus and Ukraine she debunks several myths surrounding Chernobyl and the nuclear industry in general. In fact, while there have been a small number of cases of mutations observed in some species, these are not as dramatic as the Chernobyl mythology.

  18. The Chernobyl effect

    In what way and to what extent does an event like the Chernobyl reactor accident influence the citizen's attitudes and political commitment. This book evolves a number of theses on these questions dealing above all with the determinants of political protest. Two investigations are presented in order to verify those theses: in 1982 and 1987 (some nine months after the Chernobyl reactor accident), the same persons were interviewed. In addition, representative surveys in the Federal Republic of Germany are analysed, in order to assess in general the impact of Chernobyl. From the contents: explanation model for political protest; Chernobyl effect: effect of critical events on the mobilization of political protest; discontent with nuclear energy use, political alienation and protest; internal incentives for protest: norms, readiness for aggression, and entertainment quality of protest; resources as determinants of political protest; sanctions and protest; social nets and political protest; verification of a central model of political protest, and problems encountered by research. Appendix: investigation plan and random sampling of the panel of nuclear power opponents. (orig./HP)

  1. Chernobyl: The aftermath

    The nuclear accident in Chernobyl prompted vehement and sometimes controversial public and political reaction in the Federal Republic of Germany, as it did elsewhere. What remained after the initial concern subsided? We at the IIUG feel obligated to make a contribution to the preservation and the improvement of our environmental quality, both in basic and specialized research aimed at environmental problems. It is time to take stock of the findings of our own work; we must access the feedback to and implementation of this research; the candidness and integrity of the scientific-economic-political community; superfluous knowledge or information gaps; structural obstacles and possible alternatives. This paper presents, in condensed form, the results of the 'post-Chernobyl' discussions at the IIUG, based on our work in various projects. (orig.)

  2. Accidents - Chernobyl accident

    This file is devoted to the Chernobyl accident. It is divided in four parts. The first part concerns the accident itself and its technical management. The second part is relative to the radiation doses and the different contaminations. The third part reports the sanitary effects, the determinists ones and the stochastic ones. The fourth and last part relates the consequences for the other European countries with the case of France. Through the different parts a point is tackled with the measures taken after the accident by the other countries to manage an accident, the cooperation between the different countries and the groups of research and studies about the reactors safety, and also with the international medical cooperation, specially for the children, everything in relation with the Chernobyl accident. (N.C.)

  3. Reflections on Chernobyl

    The Chernobyl and Three Mile Island reactor accidents are revealing some of the social costs of such failures, widespread opposition to nuclear power. As far as mortality and morbidity go, Chernobyl was probably a smaller incident than the chemical disaster at Bhopal. But nuclear people must accept the idea that a nuclear hazard is perceived as somehow different. Since nuclear energy will be needed to replace oil eventually, and the environmental impacts of properly operating nuclear power plants are far less than those of fossil fuelled power plants, this appears to be an appropriate time for the United States and other interested countries to start developing inherently safe nuclear power plants which will be acceptable to the public

  4. Chernobyl: Geographic considerations

    This paper discusses the geographic considerations that could effect the long range consequences of the Chernobyl accident. First, the explosion and fire lofted the radionuclides that were released, so the areas that should have been most severely effected were the areas that were downwind of the accident. Curiously, the Soviets have not mentioned the number of casualties from these areas. A second consideration is that Chernobyl is located upstream from the Dnieper River which is the source for six major reservoirs. These reservoirs provide drinking water, industrial and irrigation water, and recreational and commercial fishing for over six million people. The Soviets say that they have taken measures to prevent the radioactive contamination of the Dnieper but they neglected to explain the methods used to accomplish this feat

  5. The Chernobyl accident

    In connection with the Chernobyl accident the report gives a description of the technical features of importance to the accident, the course of events, and the estimated health hazards in the local environment. Dissimilarities in western and Sovjet reactor safety philosophy are dealt with, as well as conceivable concequences in relation to technology and research in western nuclear power programmes. Results of activity level measurements of air and foodstuff, made in Norway by Institute for Energy Technology, are given

  6. Chernobyl: a year after

    The radioactivity measurements in the year after the Chernobyl accident, carried out by the Radioprotection Division of the Joint Research Centre of Ispra, are reported. Air at ground level and in grass, milk, wheat, meat, fishes and man have been measured. The evaluation of the 1987 individual dose equivalent due to the exposure of the population living in N.W. Italy is compared with the dose equivalent absorbed in the year following the accident

  7. Chernobyl: radiation and disinformation

    A brief review is presented of the accident at Chernobyl and the delay in reporting it. A hypothesis is suggested for the cause of the accident and subsequent increase in intensity as resulting from decomposition of water and release of hydrogen at the high temperatures reached. Comments are also made on radiation levels compared with those from natural background radiation and from mass-radiography. (V.J.H.)

  8. Fallout over Chernobyl

    Friends of the Earth Ltd set up a mobile radiation monitoring unit between October and November 1988 which surveyed grass, silage, vegetables, meat in areas in Cumbria, North Wales, the Isle of Man and Scotland affected by the restrictions on the slaughter and movement of sheep following the accident at Chernobyl in 1986. This report contains the results of 357 sample analyses for CS 134 and Cs 137 examined during the survey and discusses discrepancies with official data. (U.K.)

  9. 8 years after Chernobyl

    The Chernobyl accident is the largest radiation catastrophe in its scale and prolonged consequences. Nearly 70% of radioactive materials released into the atmosphere as a result of the reactor accident have deposited at the territory of Belarus. 23% of the territory republic turned out to be contaminated with cesium 137 with radiation density 1 Ci/sq.km. 2.1 millions of people inhabited these areas in Belarus (about 20% population). More than 18000 sq.km of agricultural land (22%) and more than 20000 sq.km of forests (30% of the entire tract) have been contaminated with radionuclides. There is not a single branch of production which is not damaged by the accident at the Chernobyl NPP. After-effects of the accident tell on health of people. The increase of diseases of cardiovascular, alimentary, nervous, musculoskeletal systems, mental and lung diseases is observed in the area of radioactive contamination. Lately, the rise of thyroid cancer rates in children (from 1986 until 1994 more than 250 cases) causes particular anxiety. Nowadays, thyroid cancer is precisely considered as the direct after-effect of the Chernobyl catastrophe. Frequency of children birth with defects is nearly twice as large in the areas with density of contamination with cesium 137 radionuclides exceeding 15 Ci/sq.km. The creation of the system of radiation control is one of the main problems in elimination of the consequences of the accident at the Chernobyl NPP. Radiometers with the ability to control over Republican permissible levels of radionuclide content in food product and water have been created in the Republic. The radiation situation have been studied and the contaminated areas have been mapped. The control over radioactive contamination of air, water, sediments in carried out. (author)

  10. The chernobyl experience

    Jeschki, Wolfgang

    Numerous articles have been published about the events which occurred at Chernobyl and the radiological impact on the environment and the public. This article tries to find out which experience can be, should be or has already been gained from that accident. The fields which have been studied are: nuclear safety; radiation protection of rescue workers; medical treatment of overexposed persons; decontamination of agricultural land, buildings and cities; behaviour of radionuclides in ecosystems; effects of low doses on human beings.

  11. Chernobyl 25 years on

    After a brief recall on radioactivity measurement units and on radioactivity itself, this report describes and comments the Chernobyl accident, its consequent releases, the scattering of the radioactive plume over Europe, the formation of radioactive deposits in Europe, the contamination of the different environments and of the food chain, the health impact in the most contaminated areas, the doses received in France and their associated risks. It finally draws some lessons from this accident

  12. Return to Chernobyl

    Despite the catastrophic accident at the Chernobylsk 4 reactor in 1986, the Ukraine is currently expanding its nuclear industry. The government is committed to increasing the share of nuclear output to 40% of the country's electric power and the Chernobyl plant is included in this plan. All the Chernobyl reactors were closed down at the time of the accident, but units 1, 2 and 3 had all been restarted after safety modifications by December 1987. A fire in the turbine hall of unit 2 in 1991 resulted in the closure of that reactor and precipitated a political decision to close the entire plant by 1993. The economic consequences of such action and the safe operation of the remaining two reactors led, however, to the reversal of that decision. Work is now far advanced on unit 2 for a restart in 1996 and the management wants to upgrade all three reactors according to IAEA guidelines. Nevertheless, the question of closure of the Chernobyl plant remains in the air. A conditional acceptance of closure by 2000 has been made by the Ukraine provided the shortfall in power is taken up by a new gas-fired station. International finance is being sought for decommissioning, for urgent action on the decaying sarcophagus of unit 4, and for the gas-fired plant. Closure of the plant, given the social upheaval of the accident and recent political events, could contribute to the health of the Ukrainian national psyche. (UK)

  13. The Chernobyl nuclear accident and its consequences

    An AAEC Task Group was set up shortly after the accident at the Chernobyl Nuclear Power Plant to monitor and evaluate initial reports and to assess the implications for Australia. The Task Group issued a preliminary report on 9 May 1986. On 25-29 August 1986, the USSR released details of the accident and its consequences and further information has become available from the Nuclear Energy Agency of OECD and the World Health Organisation. The Task Group now presents a revised report summarising this information and commenting on the consequences from the Australian viewpoint

  14. Chernobyl - 20 years and beyond

    In commemoration of the Chernobyl accident 20 years ago, the French society for radiation protection (S.F.R.P.) and the Belgian society for radiation protection (B.V.S.A.B.R.) organise jointly a one day colloquium in Brussels. This colloquium is divided in two parts: the first one concerns the technical and organisational aspects of the accident with the scenario and its global impact, the international environmental radioactivity information exchange through the Chernobyl experience, the European Union (E.U.) assistance to mitigate the Chernobyl accident consequences, the crisis communication and management and the lessons learned from them; the second part is devoted to the medical and humanitarian aspects through the thyroid cancers after Chernobyl accident, the health effects in the European Union (E.U.) and the psychological factors affecting health after the Chernobyl disaster.

  16. Chernobyl - 10 years on. Proceedings of a conference organised by the Radiological Protection Institute of Ireland

    The consequences of the Chernobyl nuclear accident from an Irish perspective was the focus of a conference organised by the Radiological Protection Institute of Ireland to mark the tenth anniversary of the accident. The health consequences of Chernobyl were discussed along with presentations on such issues as the hazards to the Irish population from Sellafield; the radiation hazard posed by radon gas; radiation hazards in medicine, industry and education, and Ireland's National Emergency Plan for Nuclear Accidents

  17. Evaluation investigation 'Chernobyl'

    This report is an evaluation of the attitude of the Dutch government in response to the Chernobyl accident. It deals with measures taken by the government in order to minimize the (possible) effects, apparent shortcomings and how one has dealt with them, measures which can be taken at least by the Netherlands in case of a reactor accident given the presence of dozens of nuclear power plants in Europe. Good and less good aspects of the temporary organization are noted and some general recommendations are given. (Auth.)

  18. US perspective on Chernobyl

    The Soviet medical response to the Chernobyl catastrophe was impressive and demonstrated an enviable level of radiobiologic competence. It also afforded the first opportunity to test the usefulness of bone marrow transplantation as life saving therapy for heavily irradiated patients under emergency conditions. More than 135,000 persons were at risk of exposure to life-threatening levels of radiation. A remarkably engineered evacuation of this population prevented the medical consequences from becoming worse than they were. Our medical perspective is based on the 40-year history of radiation incidents worldwide and especially in the United States

  19. Chernobyl, fifteen years after

    This work has been constituted around four questions: the future of the Chernobyl site, the damaged reactor, and the sarcophagus around it; the health consequences of the accident on the persons that have worked on the damaged reactor and on the population in the countries the most exposed to fallout,; the situation of contaminated territories around the power plant and their management today; the last question concerns especially the France with the consequences of the radioactive cloud and what we know about the health risks induced by this event. (N.C.)

  20. Chernobyl - and then?

    The report describes how the different parties of the nuclear debate react to, and deal with, the information that arises on the issue, i.e. the process that leads to decision making. After the Chernobyl accident, a public enquiry was made, to form a base for decisions regarding the future energy policy of Sweden, including the phasing-out of nuclear power. The differing interpretations and uses of the results of this enquiry are studied, in the hope to clarify and separate factual and value-based appreciations of different energy policy alternatives

  1. Chernobyl: an early report

    An overview and assessment of the nuclear accident at Chernobyl is presented. The authors have assembled data from throughout Europe to estimate upper bounds for the possible radiation releases from the accident, the exposures these may produce in humans, and the health consequences that may follow. Measurements of radioactivity in air, fallout, and milk and other food are included. Doses from the accident are compared with those from other sources of radiation exposure and a comparison is made of the annual risk of cancer from this and other causes

  2. The accident of Chernobyl

    RBMK reactors (reactor control, protection systems, containment) and the nuclear power plant of Chernobyl are first presented. The scenario of the accident is given with a detailed chronology. The actions and consequences on the site are reviewed. This report then give the results of the source term estimation (fision product release, core inventory, trajectories, meteorological data...), the radioactivity measurements obtained in France. Health consequences for the French population are evoked. The medical consequences for the population who have received a high level of doses are reviewed

  3. Chernobyl' 94. Abstracts

    This book contains materials of the 4th International Scientific and Technical Conference devoted to the results of 8-years work on Chernobyl accident consequences mitigation. Main results of research in radiation monitoring, applied radioecology, effect of radionuclides on biological objects in contaminated territories are presented. Information about waste management and medical consequences of the accident is given. Methodology and strategic of further research on radionuclides in environment and their influence on living organisms is determined. Large factual materials and its generalization may be usefull for scientists and practical workers in the field of radiation monitoring, radiology and medicine

  4. Chernobyl: the long shadow

    Chernobyl: the Long Shadow offers a balanced review of what happened there, why and how it happened, and what the main lessons and implications of the accident are. It looks back on events during and after the disaster, in particular reviewing how it and the radiation fallout were dealt with in different countries, and looks forward to how the incident might affect the nuclear power industry around the world. The book explores the significance of the accident within the Soviet Union, considers its impact on public confidence in nuclear power, and reviews what improvements are necessary in emergency planning throughout the rest of the world. It is written from an inter-disciplinary perspective; based on detailed scientific research, which is described in non-specialist terms, it considers themes like attitudes to nuclear power and political reactions to the accident itself. It sets the Chernobyl accident into a proper context, and will appeal to students and teachers of geography, environmental science, international politics, nuclear physics, and to anyone interested in current affairs and environmental problems. (author)

  5. Chernobyl, an opinion

    After having recalled the circumstances of the Chernobyl accident, and given some indications of associated releases (iodine 131, caesium 134 and 137), the authors gives an overview of biological effects of radiations: generalities (doses, biological effects), results of epidemiological studies in terms of stochastic effects of radiations (for survivals of atomic explosions, in other epidemiological studies, in epidemiological studies related to thyroid), of relationship between dose and effect in the case of low doses (generalities, risk coefficients), and of extrapolation. In the next part, the authors discuss the health consequences of the accident in the former USSR and in the world: consequences noticed by the end of 2000 (non stochastic effects, stochastic effects like occurrence of thyroid cancers or of leukaemia, exposed populations, occurrence of other cancers), predictions of impacts and death on a long term due to stochastic effects (for thyroid cancers, leukaemia and other cancers), global assessment. Then, they discuss the impact of the Chernobyl accident: generalities, doses delivered to the whole body, thyroid cancers

  6. Dispersion modelling after Chernobyl

    At the time of the Chernobyl accident, little was known about the magnitude and time pattern of the release from the damaged reactor. This paper describes the detective work done in the weeks following the accident to assess the release and its dispersal across Europe; also new calculations done since the USSR presentations in Vienna at the end of August 1986 and some estimates of longer term collective dose commitment are given. The MESOS computer model developed at Imperial College to simulate the dispersal of hypothetical accidental releases of important radionuclides, out to distances of several hundred kilometers, and estimate levels of contamination in the air and deposited on the ground, was adapted for real time use. Combined with meteorological data and measurements of radionuclides collected from miscellaneous sources across Europe, it was possible to estimate how much had been released. To conclude, some general remarks are made about the implications of the Chernobyl accident for technical support in emergency procedures for any future nuclear accident. (UK)

  7. The Chernobyl accident

    The accident at Unit 4 of the Chernobyl nuclear power plant was the most severe in the nuclear industry. The accident caused the rapid death of 31 power plant employees and firemen, mainly from acute radiation exposures and burns, and brought about the evacuation of 116,000 people within a few weeks. In addition, about half a million workers and four million members of the public have been exposed, to some extent, to radiation doses resulting from the Chernobyl accident. A large number of radiation measurements have been made since the accident in order to reconstruct the doses received by the most exposed populations. On the basis of currently available information, it appears that: (1) average doses received by clean-up workers from external irradiation decreased with time, being about 300 mGy for the persons who worked in the first three months after the accident, about 170 mGy for the remainder of 1986, 130 mGy in 1987, 30 mGy in 1988, and 15 mGy in 1989; (2) the evacuees received, before evacuation, effective doses averaging 11 mSv for the population of Pripyat, and 18 mSv for the remainder of the population of the 30 km zone, with maximum effective doses ranging up to 380 mSv; and (3) among the populations living in contaminated areas, the highest doses were those delivered to the thyroids of children. Thyroid doses derived from thyroid measurements among Belarussian and Ukrainian children indicate median thyroid doses of about 300 mGy, and more than 1% of the children with thyroid doses in excess of 5000 mGy. A description is provided of the epidemiological studies that the National Cancer Institute has, since 1990, at the request of the Department of Energy, endeavoured to undertake, in cooperation with Belarus and Ukraine, on two possible health effects resulting from the Chernobyl accident: (1, thyroid cancer in children living in contaminated areas during the first few weeks following the accident, and (2) leukaemia among workers involved in clean

  10. About Chernobyl - Twenty Years Later

    The author discusses the reactor accident of Chernobyl, the information on its consequences so contradictory in the former USSR countries, the status of the effects observed, the forecasting concerning the onset of cancers in the coming years among the populations that were exposed to radiations, the public opinion facing the pessimists. He concludes on the lessons which can be drawn from Chernobyl. (A.L.B.)

  11. Bhopal and Chernobyl: some comparisons

    An attempt is made to compare some aspects of the accidents at Bhopal and Chernobyl, their causes and consequences. There were design and management inadequacies in both cases, Maintenance inadequacies were plenty in Bhopal but not in Chernobyl. Written instructions were unsatisfactory in Bhopal. In Chernobyl the operators deliberately violated the instructions repeatedly; this compounded by the unsatisfactory nature of reactor design, led to the accident. Disaster management preparedness and emergency response were excellent at Chernobyl. At Bhopal the plant management was absolutely unprepared and contributed practically nothing to the emergency management; however, civil and military authorities did a splendid job. Immediate deaths in Bhopal are estimated to be 2,500 to 10,000 and the number affected 200,000. None of the plant staff were affected and all the casualties were in non-plant personnel living nearby. All the 31 deaths in Chernobyl were among the plant personnel. Although 135,000 persons living in a 30 Km zone round the reactor were evacuated and medically examined, none had to be hospitalised. The world scientific community seems to have forgotten Bhopal within a year or so after the accident, while Chernobyl continues to excite intense interest. Extensive knowledge of the biological effects of radiation helps to estimate the likely number of cancer and genetic effects from Chernobyl. Knowledge of Methyl iso cyanate (MIC) toxicology is woefully inadequate; recent evidence indicates the possibility of carcinogenic and mutagenic effects of MIC. Both at Bhopal and Chernobyl there are elaborate plans for detailed followup of the populations for several decades. (author). 17 refs., 3 tabs

  12. Some problems of invalids of Chernobyl

    The consequences of the Chernobyl catastrophe caused health disorders of the liquidators, and as a result many of them became handicapped. The rate of health disorders among the invalids of Chernobyl is a few times higher than that of other citizens of the country. The invalids of Chernobyl need constant support, social help, medical rehabilitation and qualified medical care. Invalids of Chernobyl suffered from the consequences of the Chernobyl Catastrophe most of all. We are turning to foreign charity organizations for help in creating the Center of Psychological Support and organizing working places with flexible hours for Invalids of Chernobyl. (Authors)

  13. Chernobyl health effects

    On 26 April 1986, a few short minutes were not enough to destroy one of the four nuclear reactors at Chernobyl and cause, over the next few weeks, the deaths of 31 people from among the staff, rescuers and firefighters who had dealt with the accident and prevented the spread of the catastrophe to the other three reactors on the site. The experts and the authorities soon recognized that the consequences of this event for the environment and for the surrounding populations would last several decades. Forecast estimates from very diverse sources of the nature and extent of these consequences came thick and fast, particularly in the years 1986 and 1987. Unfortunately, they differed so greatly in both time and space that they lacked all credibility. As the news spread through the public, it could only worsen a social climate which was already seriously upset by the effects of the catastrophe itself. 55 refs

  14. Environmental radioactivity from Chernobyl

    A broadly based programme of environmental measurements following the Chernobyl accident is summarised and discussed. Levels of radionuclides in air and atmospheric deposition were increased substantially for a period of some weeks following the accident. The quantity of 137Cs in surface soils was doubled in some regions of the North and West of the UK. Observations of the rates of deposition and resuspension, and weathering from grass, a river catchment and buildings, provided confirmation of several aspects of the environmental behaviour of 137Cs, and extended understanding of these processes. Levels of 137Cs in imported crops and in individuals in S. England, and the brief increase in external radiation, were generally low, confirming that the dose to the regional population was small.

  15. Health effects from Chernobyl

    There are many misconceptions of the effects on health from the accident at Chernobyl. The 1996 conference in Vienna held one decade after the event, and more recent material being examined by UNSCEAR, provide a more soundly-based view. Apart from an increase in thyroid cancer in some of those people exposed as children, there is no evidence of a major public health impact to date from radiation exposures caused by the accident. There is no increase in leukemia attributable to radiation exposure, the most likely indicator, even in the group of radiation workers. Definitive studies of the health status of the various groups involved have been difficult to carry out because of the socio-economic conditions. Clearly, their continuation is going to need further international cooperation. (author)

    This collection includes the materials, in which are, from one hand, the results of previous years works aimed at mitigation of Chernobyl accident aftermath and decrease of 'Ukryttia' object impact to surrounding environment are generalized and summed up, and from another hand, decisions and technologies are seen that are aimed at decrease of nuclear and radiation safety during the works of converting 'Ukryttia' object into an ecologically safe system. over fifteen years passed from the accident moment a rich experience in overcoming the accident aftermath has been accumulated and a great volume of experimental and theoretical data was gained, that is becoming as a base for further developments and testing of new technologies of 'Ukryttia' object rad waste management, lowering of risks during the works of 'Ukryttia' object conversion, improvement of its nuclear and radiation safety

  17. Ten years after Chernobyl

    As was amply demonstrated during the EU/IAEA/WHO Summing-up-Conference in Vienna, Austria, April 8-12, 1996, the radiological consequences of the Chernobyl accident were, fortunately, not as serious as frequently presented in the media: 28 people died from acute radiation syndrome in 1986, 14 more of possibly radiation-related causes since. Of the <1000 thyroid cancers in children, 90 to 95% are curable. There have so far been no other demonstrable increases in the former Soviet Union, as well as in Western Europe, of leukemias, solid cancers, or genetic defects, nor are any to be expected in the future. Even among the open-quotes liquidatorsclose quotes with doses ∼100 mSv, of the ∼150 additional expected leukemias during the 10 yr after the accident, none have been observed. The economical, social, and political consequences, however, both in the former Soviet Union and in Western Europe, have been very substantial. Whole countries developed an hysterical 'radiation sickness.' As A. Merkel, the German Minister of Environment and Reactor Safety, who chaired the conference, pointed out, 'the radiation sensitivity of societies far exceeds that of individuals.' It is obvious that important groups in Ukraine, Belaurus, and Russia try to blame a large fraction of all economic, social, and health problems during the last decade, which are substantial (∼ 6 yr less life expectancy, twice the homicides and traffic deaths, increased alcoholism, and so forth), on radiation of the Chernobyl accident in an effort to attract more support. Western scientists refute such claims but admit large non-radiation-related problems caused by the accident

  18. The Chernobyl cloud would have stopped at the borders

    The author proposes a retrospective overview and analysis of information published either by involved agencies or by media after the Chernobyl accident about the presence or absence of radioactive fallouts in France. While defending Professor Pellerin, the author acknowledges some mistakes made by authorities in their communication, but also outlines that some realistic and clear information published by the SCPRI or the CIPR have been quickly forgotten by the media. The author analyses the different publications and communiques made by authorities, agencies and media over different periods: from April to May 1986, in 1999 when Professor Pellerin filed a defamation lawsuit against authors of a book, and when an ecologist politician was also sentenced. The author then proposes a discussion of health consequences of Chernobyl in France, and analyses the controversy on this issue during the 1997-2006 period. He comments the content of a report published in March 2006 by the IRSN scientific committee

  20. Challenger and Chernobyl: lessons and reflections

    The primary cause of the Challenger accident was the failure of O-ring seals in the solid rocket booster, a subcomponent which had been known to be faulty for some time. When Hans Mark was the most senior engineering member of the NASA management executive team, he had asked for a complete review of these subcomponents; this was not done. The accident to the Chernobyl atomic reactor has not been publicly analyzed to the same extent as the Challenger explosion, and hence there must remain some speculation as to the detailed sequence of events. The lessons from both accidents are clear: faulty human understanding the the equipment and the lack of education, training and discipline were critical. The authors conclude that the Shuttle will fly again soon, and that political problems in the Soviet Union may be great and may force some changes. (author)

  3. Chernobyl the health consequences

    This paper focuses initially on selected aspects of the health impact of the Chernobyl accident, and then goes on to discuss some of the pitfalls involved in trying to assess the health detriment in isolation and without regard for the context in which it occurs. The accident on 26 April 1986 was unique. Two explosions, followed by a graphite fire in the destroyed reactor, not only dispersed radionuclides high into the atmosphere, but the fire was instrumental in ensuring the continued dispersion for about ten days. This prolonged discharge into the atmosphere combined with changes in wind direction ensured that radionuclides were widely distributed over Europe and were even detected throughout the Northern Hemisphere. The actual ground deposition was very variable, depending on may factors such as coincident rainfall during the passage of the plume, wind speed and direction, and the topography of the terrain. The mosaic distribution of the ground deposition became much more variable with distance from the site, and is responsible for the wide range of individual doses that characterises this accident. The paper details the health effects of the accident on those immediately involved, and also the delayed health effects, including increased incidence of thyroid cancer, among the populations of surrounding areas of Ukraine, Belarus and Russia. It also discusses the widespread psychosocial detriment which resulted from the accident. Finally, the paper evaluated the efficacy of decontamination measures which were adopted in the affected areas in the years following the accident

  7. Consequences of the Chernobyl accident

    The techniques currently used in off-site consequence modelling are applied to the Chernobyl accident. Firstly, the time dependent spread of radioactive material across the European continent is considered, followed by a preliminary assessment of the dosimetric impact (in terms of collective and mean individual doses) on the various countries of Eastern and Western Europe. The consequences of the accident in the USSR are also discussed. Finally, the likely implications of the Chernobyl event on research in the field of environmental consequence assessment are outlined.

  8. Chernobyl - considerations of an insurer

    The author underlines the insurers' reactions after the Chernobyl accident. Firstly, their reactions as providers of security for loss and destruction in power plants and for third party liability: offers of financial cover have not been affected - quite the contrary - since 26 April 1986. He then refers to their consideration of the detrimental consequences: Chernobyl has revealed a new aspect of nuclear incidents - the addition of various types of expenditure quite apart from compensation of personal injury or property may considerably increase their economic impact (NEA)

  9. Post-Chernobyl emergency planning

    This report is the result of a study ordered by the Swedish Nuclear Power Inspectorate and the National Swedish Institute of Radiation Protection to evaluate the measurements taken in Sweden in response to the Chernobyl accident. The enquiry was also given the task of suggesting improvements of the nuclear accidents emergency planning and other activities relevant to nuclear accidents. Detailed accounts are given of the course of events in Sweden at the Chernobyl accident and the steps taken by central or local authorities are discussed. Several alterations of the emergency planning are proposed and a better coordination of the affected organizations is suggested. (L.E.)

  10. Chernobyl catastrophe: An unexpected result

    Six years ago, the Chernobyl-4 reactor has exploded. During 10 days , an important part of radioactive products of reactor heart has been ejected in the atmosphere, shaping a radioactive cloud whose the trajectories and fall-outs on all Europe have worried the public opinion. The author, J.C. Nenot and R. Coulon, 6 years after, take stock of the ecological, agricultural and sanitary consequences and if the ecological effects are in a good issue of regression, even near to Chernobyl, on the other hand in medical and sanitary scopes stay uncertainties. 8 refs., 4 figs

  11. Chernobyl reactor accident

    Following the accident at Chernobyl nuclear reactor, WHO organized on 6 May 1986 in Copenhagen a one day consultation of experts with knowledge in the fields of meteorology, radiation protection, biological effects, reactor technology, emergency procedures, public health and psychology in order to analyse the development of events and their consequences and to provide guidance as to the needs for immediate public health action. The present report provides detailed information on the transportation and dispersion of the radioactive material in the atmosphere, especially volatile elements, during the release period 26 April - 5 May. Presented are the calculated directions and locations of the radioactive plume over Europe in the first 5 days after the accident, submitted by the Swedish Meteorological and Hydrological Institute. The calculations have been made for two heights, 1500m and 750m and the plume directions are grouped into five periods, covering five European areas. The consequences of the accident inside the USSR and the radiological consequences outside the USSR are presented including the exposure routes and the biological effects, paying particular attention to iodine-131 effects. Summarized are the first reported measured exposure rates above background, iodine-131 deposition and concentrations in milk and the remedial actions taken in various European countries. Concerning the cesium-137 problem, based on the UNSCEAR assessment of the consequences of the nuclear fallout, one concludes that the cesium contamination outside the USSR is not likely to cause any serious problems. Finally, the conclusions and the recommendations of the meeting, taking into account both the short-term and longer term considerations are presented

  12. Reports of the Chernobyl accident consequences in Brazilian newspapers

    The public perception of the risks associated with nuclear power plants was profoundly influenced by the accidents at Three Mile Island and Chernobyl Power Plants which also served to exacerbate in the last decades the growing mistrust on the 'nuclear industry'. Part of the mistrust had its origin in the arrogance of nuclear spokesmen and in the secretiveness of nuclear programs. However, press agencies have an important role in shaping and upsizing the public awareness against nuclear energy. In this paper we present the results of a survey in reports of some Brazilian popular newspapers on Chernobyl consequences, as measured by the total death toll of the accident, to show the up and down dance of large numbers without any serious judgment.

  16. Chernobyl - a Canadian technical perspective

    On April 26, 1986, the Number 4 reactor at the Chernobyl Nuclear Power Station in the Soviet Union suffered a severe accident which destroyed the reactor core and led to a loss of life. The four reactors at this station are of the RBMK-1000 type - boiling-light-water cooled, graphite moderated, vertical pressure-tube reactors, each generating 1000 MW of electricity through two turbines. AECL has carefully studied the accident, and the design of Chernobyl, to see if anything has been overlooked in the CANDU design. This report reviews the results of that study, in particular the relevant features of the Chernobyl design which exacerbated the accident, and compares them to the CANDU 600 design. A number of issues (the sign of the void coefficent and the pressure-tube design) have also been given some international prominence in the post-Chernobyl analysis; these are discussed in this report and shown to be irrelevant to the CANDU design. Finally this report describes the subjects identified for further design follow-up in Canada

  19. Cell damage seen from Chernobyl

    The 30 kilometer radius forbidden zone around the Chernobyl atomic plant serves as a sobering reminder of the world's worst nuclear accident. But for former Soviet biologists, it's also a unique natural laboratory. And one scientist, Nadejda Gulaya of Kiev's Pallaguine Institute of Biochemistry, has been doing studies that she claims offer surprising evidence of Chernobyl's after-effects. Prolonged exposure to radioactive fallout from the 1986 accident, she says, has caused damage to cell membranes in both animals and humans. For the past year, Gulaya has been comparing tissues from animals such as mink, pigs, and rodents inhabiting the Chernobyl area with those from other parts of Ukraine. Her conclusion: Exposure to radiation has, in many cases, caused alterations to membrane phospholipids. These changes, are similar to those that disrupt cellular metabolism following exposure to oxidizing free radicals. Gulaya also has preliminary data from human studies. She claims to have found similar alterations in the neurons of people who have died since being exposed to Chernobyl radiation. That leads her to speculate that the frequent psychiatric disorders may not just be from mental stress or radiophobia, but might reflect actual damage to the central nervous system

    Two cae-control studies among Chernobyl liquidators- one of leukaemia and non-Hodgkin lymphoma (NHL), the other of thyroid cancer risk were carried out in Belarus, Estonia, Latvia, Lithuania and Russia. These studies were coordinated by the International Agency for Research on Cancer. The specific objective of these studies was to estimate the radiation induced risk of these diseases among liquidators of the Chernobyl accident, and, in particular, to study the effect of exposure protraction and radiation type on the risk of radiation induced cancer in the low to medium (0-500 mSv) radiation dose range. The study population consisted of the approximately 15.000 Baltic countries, 66 000 Balarus and 65 000 Russian liquidators who worked in the 30 km zone in 1986-1987, and who were registered in the Chernobyl registry of these countries. The studies included cases diagnosed in 1993-1998 for all countries but Belarus, where the study period was extended until 2000. for controls were selected in each country from the national cohort for each case, mateched on age, gender and region of residence. Information on study subjects was obtained through face-to-face interview using a standardised questionnaire with questions on demographic factors, time place and conditions of work as a liquidator and potential risk and confoundinf factors for the tumours of interest. Ocerall 126 cases of leukaemia and NHL, 119 cases of thyroid cancer and 1060 controls were interviewed. Individual estimates of kerma in air and of dose to the bone marrow and related uncertainties were derived for each subject in the leukaemia and NHL study, using a method of analytical dose reconstruction developed whiting the study. Estimates of individual doses to the thyroid from external exposures, I-131 and long-lived isotopes were derived for all subjects in the thyroid case-control study. Dose-response analyses have been carried out. Resulting risk estimates will be presented and compared to risk estimates

  2. Challenges to decision makers after urban contamination: The Chernobyl experience

    The real history of the Chernobyl decisions will probably be published in ten or fifty years after the death of the politicians who made those decisions and the soviet scientists who were there creating them. But that is not out of the possibility that real and tragic history will never be published at all. This is mainly because the most hard and responsible Chernobyl decisions which had to be made in the situation of acute time, skill and information deficit, had been marked by the stamp of time and society where all of us, including the authors, were living. Never before, and I hope very much, never in the future, has humanity faced the industrial nuclear-radiation accident with the scale like Chernobyl NPP accident. So it's extremely important to summarise and put together not only the scientific but human experience of the scientists which directly formed the large-scale decisions. It is very important to explain to society not only the scientific background of those decisions but also the scientists' personal views, their personal impressions as at the time of decision making as in eight years after the accident.

    This report draws an account of the consequences of Chernobyl accident 14 years after the disaster. It is made up of 8 chapters whose titles are: (1) Some figures about Chernobyl accident, (2) Chernobyl nuclear power plant, (3)Sanitary consequences of Chernobyl accident, (4) The management of contaminated lands, (5) The impact in France of Chernobyl fallout, (6) International cooperation, (7) More information about Chernobyl and (8) Glossary.

  4. Chernobyl victims: realistic evaluation of medical consequences of Chernobyl accident

    Objective assessment of early and delayed medical consequence of the Chernobyl accident is presented. Mortality of people due to acute radiation disease, burns and mechanical injuries are attributed to the early effects. Oncological and genetic diseases are considered as the delayed effects. Delayed radiation effects on the residents of contaminated territories were estimated by epidemiologic examination taking into account the dose due to radioactive fallout. Certain regions of Belarus, Russia and Ukraine were mostly exposed to contamination. Contamination density by 137Cs is considered and radiation doses due to natural sources and Chernobyl accident are compared. Disease incidence is analysed for carcinoma and genetic diseases. Health hazard caused by non-radiation accidental factors (psychological stress, victim psychology thrusting, groundless evacuation) is assessed

  5. Social Chernobyl participants condition in Lithuania

    Full texts: At the moment in Lithuania live almost 6 600 Chernobyl participants (persons witch were in attendance Chernobyl nuclear power station emergency ravage liquidation works and executing another works in 30 kilometers zone). About 770 died and 170 went to other nations. Thievery other fixed illnesses coherence with being in 30 kilometers zone. According 26 October, 1990 Republic of Lithuania government's resolution No. 325 intended that Chernobyl participants credit accomplishes Ministry of Social care but until now in the Republic there is not undivided database, consequently we use different institution's and social investigations information which is not circumstantial. Chernobyl participants social condition and medicine service control certificates, government's resolutions and Ministry of health care and work and Ministry's of health care requisitions. There is not a law which guarantees Chernobyl participants social rights. Supposedly that for in Lithuania there is not the logistics which could vouch medical facilities provision for Chernobyl participants. Until 2005 sanatorium treating of Chernobyl participants was pursuance through invalids till but this treatment was not available to everyone Chernobyl participant for two reasons: 1 - Vicinities doctors and GPs not all the time contemprorize illnesses with being in The nuclear power station of the Chernobyl zone. 2 - Invalids till was not fixing the number of the permissions to the sanatoriums for the Chernobyl participants. Since 13 September, 2005 by Republic of Lithuania government's resolution No. 998 municipal governments budget bankrolls once a year may offset eighteen-days sanatorium treatment for persons which were liquidating The nuclear power-station of the Chernobyl emergency ravage but Chernobyl participants should give Specialists committee inference. Another problem social security. Chernobyl participant's requirement supply if they ill or died according Government's 18 February

  6. Belorussian population health state following the Chernobyl accident

    Environmental radioactivity peculiarities at the Belarussian territory resulted from the Chernobyl accident are analysed. Main risk systems for human health and trends of potential pathology formation are determined. Growth in the disease incidence in adults and especially in children is marked. It covers thyroid cancer (due to 131I intake in the early period of the accident), chronic neoplasms in hematopoietic and lymphatic systems, immune system, digestive system, cardiovascular and neuromental diseases. Attention is paid to the genetic radiation effects, pregnancy and delivery pathology. 2 tabs

  7. Twenty years after the Chernobyl accident

    nuclear power to meet increasing energy demands in many parts of the world. In 2001, after taking note of the conflicting views on the results of the accident, I called for the creation of a Chernobyl Forum, inviting the world's foremost scientific experts to conduct an exhaustive assessment of the health, environmental and social impacts of the accident. As with all IAEA programmes, we emphasized an impartial, fact based approach to the analysis of this difficult and highly charged topic. I was pleased that, after a long period of careful analysis, the parties involved - including the World Health Organization and seven other specialized United Nations agencies, as well as the Governments of Belarus, Russia and Ukraine - were able to achieve consensus on the set of authoritative reports that were issued last September. But the Chernobyl Forum had another purpose as well. My hope was that, by giving clear, impartial answers about the accident and its effects, we would be able to focus more effectively on present and future needs. Better international cooperation on assistance to the people and regions affected by the accident. Smarter approaches to safe food production and effective health care. Enhanced investments in the people concerned, in ways that would give them control over their own livelihoods. In short, it was my hope that, by answering questions about the past, we could restore a vision of a brighter future for the regions concerned. And that remains my hope. We will not soon forget the Chernobyl accident. We will not forget the emergency workers who gave their lives. We will not forget the health and environmental consequences. And we should never forget the lessons we learned regarding nuclear safety and international cooperation. In remembering the Chernobyl accident, we should renew our determination to ensure that such a tragedy will not happen again. But we must also remember the survivors, the individuals and communities who seek to move forward with

  8. Tracking the cloud from Chernobyl

    In the aftermath of the accident at Chernobul nuclear power station, many scientists are studying how the radionuclides from the reactor's core dispersed across Europe and became deposited on the ground. A group in the Department of Mechanical Engineering at Imperial College have developed a computer model, MESOS, specifically to study the transport of pollutants in the atmosphere over very large distances. In the past, this model has been used to study the potential consequences of hypothetical accidents at nuclear power plants in neighbouring countries. Now it has been used to estimate where the radioactivity from Chernobyl went. The Chernobyl model is explained and some estimates from the MESOS model are presented. By comparing the model estimates with observations a full assessment of the environmental consequences of the accident will be possible. It should be possible to find out the way in which pollutants travel long distances, how they are deposited on the ground and their transport through food chains. (U.K.)

  9. Monstrosities - an outcome of Chernobyl?

    In the western parts of Turkey, which have been particularly hard hidden by the radioactive fallout from the Chernobyl reactor accident, an extremely high number of malformations in newborns have been recorded. There is reason to attribute this to the high radioactivity level measured in this region after the accident. But most radiation experts refuse to accept any connection between the miscarriages or malformation and the reactor accident. (orig./HP)

  10. Chernobyl: Insight from the inside

    The author dispenses with the usual detachment of historical analysis and tells what happened in Chernobyl in April through the unshielded and horrified perceptions and largely unedited language of those who were there. A common thread running through the book is the duplicity of Soviet officials, particularly in reference to the 650,000 emergency workers. The author maintains that the accident would have been avoided if the reactor design had not been inherently flawed, unadmitted by Soviet officials

  11. The reactor accident of Chernobyl

    The contamination, caused by the radioactivity released during the reactor accident of Chernobyl was measured in samples taken in the environment of the Karlsruhe Nuclear Research Center. The radioactivity was determined in air, fodder, milk, vegetables, other plants, foodstuffs, soil, precipitations, drinking water, sludge and other samples. Results of measurements are reported which were received with considerably more than 1000 samples. The evaluation of the data will be presented in KfK 4140. (orig.)

  12. Chernobyl reactor transient simulation study

    This paper deals with the Chernobyl nuclear power station transient simulation study. The Chernobyl (RBMK) reactor is a graphite moderated pressure tube type reactor. It is cooled by circulating light water that boils in the upper parts of vertical pressure tubes to produce steam. At equilibrium fuel irradiation, the RBMK reactor has a positive void reactivity coefficient. However, the fuel temperature coefficient is negative and the net effect of a power change depends upon the power level. Under normal operating conditions the net effect (power coefficient) is negative at full power and becomes positive under certain transient conditions. A series of dynamic performance transient analysis for RBMK reactor, pressurized water reactor (PWR) and fast breeder reactor (FBR) have been performed using digital simulator codes, the purpose of this transient study is to show that an accident of Chernobyl's severity does not occur in PWR or FBR nuclear power reactors. This appears from the study of the inherent, stability of RBMK, PWR and FBR under certain transient conditions. This inherent stability is related to the effect of the feed back reactivity. The power distribution stability in the graphite RBMK reactor is difficult to maintain throughout its entire life, so the reactor has an inherent instability. PWR has larger negative temperature coefficient of reactivity, therefore, the PWR by itself has a large amount of natural stability, so PWR is inherently safe. FBR has positive sodium expansion coefficient, therefore it has insufficient stability it has been concluded that PWR has safe operation than FBR and RBMK reactors

  19. The Chernobyl reactor accident source term: Development of a consensus view

    In August 1986, scientists from the former Soviet Union provided the nuclear safety community with an impressively detailed account of what was then known about the Chernobyl accident. This included assessments of the magnitudes, rates, and compositions of radionuclide releases during the ten days following initiation of the accident. A summary report based on the Soviet report, the oral presentations, and the discussions with scientists from various countries was issued by the International Atomic Energy Agency shortly thereafter. Ten years have elapsed since the reactor accident at Chernobyl. A great deal more data is now available concerning the events, phenomena, and processes that took place. The purpose of this document is to examine what is known about the radioactive materials released during the accident. The accident was peculiar in the sense that radioactive materials were released, at least initially, in an exceptionally energetic plume and were transported far from the reactor site. Release of radioactivity from the plant continued for about ten days. A number of more recent publications and results from scientists in Russia and elsewhere have significantly improved our understanding of the Chernobyl source term. Because of the special features of the reactor design and the pecularities of the Chernobyl accident, the source term for the Chernobyl accident is of limited applicability of the safety analysis of other types of reactors

  20. Chernobyl sufferers in Ukraine and their social problems: short outline

    This paper describes the historical review on the Chernobyl catastrophe. The state was badly prepared to a disaster of such a scale as Chernobyl and most of necessary decisions were drafted and taken immediately when they were needed. Fortunately in the initial period there were material and resources available and a mechanism of direction was in place. The mechanism was not perfect, and its quality was quickly deteriorating. The executive power of the USSR -Council of Ministers and numerous ministries- behaved practically independently from the Supreme Soviet Parliament until 1989. The first period was marked by attempts to hide and to diminish the consequences. The Law had been passed by the Parliament of Ukrainian SSR on 28 february, 1991. Later the Law underwent some serious amendments in 1992, 1993, 1996, mainly because an application of the Law revealed some economic miscounts. Some controversial provisions of the law, like the tax exempt status of the organizations working in the contaminated area, and the import laws for the Chernobyl organizations have been already revoked. In this paper we will pay special attention to informal non-governmental help from international community. Few projects of international organizations, very often quite negatively perceived by Ukrainian people, require separate analysis.The goal of these projects was to offer research assistance to respective Ukrainian institutions and thus these projects were to some extent not directly aimed at suffers, but at some medical problems. Intergovernmental assistance to suffers was quite limited. Ukrainian writers were the the first who begun campaign to disclose the truth of Chernobyl in Ukraine. In 1998 the first green' NGO was created in Ukraine. These NGOs played an important role of pressure groups. Often local politician were using supports from these groups in their election campaigns and legislative works. Separate investigation is needed to asses the role and results of activities

  1. Health effects of Chernobyl: newer perspectives

    On the 26th of April 1986, the 4th unit of the Chernobyl Nuclear Power Plant in the former Soviet Union exploded, following a scheduled but not-well-planned testing of a turbo-generator prior to a shutdown of the reactor. This led to a release of large amounts of radioactive material into the atmosphere, resulting in a cloud not only over in the Soviet Union, but due to prevailing meteorological condition, over the Eastern Europe as well. Over the past ten years, a large number of agencies in the areas of human health and hygiene, agriculture and veterinary sciences in addition to those involved in radiation protection and radiation safety have studied the impact of the accident. These studies were also extended to evaluate and mitigate the consequences. The accident has been a warning, and has provided lessons in mitigating the consequences of any industrial accident. Newer perspectives have emerged in the area of early diagnosis and treatment of the acute effects of radiation. Research in the areas of genetics, molecular biology and radiation biology will contribute to better medical care in future. (author). 3 tabs

  2. Assessment of Chernobyl health consequences under the influence of public and other interests

    The Chernobyl reactor accident on 26 April 1986 was the largest and most severe disaster in the history of civil nuclear technology involving radiation exposure and radioactive contamination of large areas in the NIS. Among the three countries Belarus, Russia and Ukraine, Belarus was mostly affected, because about 70% of the radioactive fallout was deposited on its territory. The radiation doses from various nuclides, to which the public as well as the liquidators were exposed during the first months, let expect serious health consequences for a large number of persons. During the first weeks after the accident, the authorities in Moscow released several orders of secrecy. Later, in July 1987 the order was given that acute and chronic diseases of liquidators, who were exposed to less than 50 rem, must not be attributed to the effects of ionizing radiation. In 1990, the International Atomic Energy Agency (IAEA) organized the International Chernobyl Project, with the participation of the Commission of the European Communities, the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the World Health Organisation (WHO) and others, in order to investigate and assess the radiological situation in the three affected Soviet Republics. 200 scientists from the West and 500 from USSR were sent by their governments to participate. Concerning the health impact, the IAEA team under its chairman professor F. Mettler from USA concluded in 1991 that there were no health disorders that could be attributed directly to radiation exposure. IAEA favoured psychological stress and anxiety to be the cause of health disorders observed. This information was spread world wide. But in reality, at this time the number of thyroid cancer cases in children in Belarus was already 30 times higher than the average in the 10 years before Chernobyl. And IAEA and other international organizations did not want to take into account the findings and reports of Belarusian and

  3. Chernobyl fallout in Great Britain

    Chernobyl deposition in the UK was sampled in May and October 1986 and in June of 1987. The sampling concentrated on grassy vegetation but in October 1986 other vegetation, soils and wildlife were included. Deposition patterns have been established and a greater degree of retention and recycling indicated for the organic soils of upland Britain. For wild animals concentration factors varied not only between species but with sex and age. Highest tissue concentrations were recorded in species feeding on heather (Blue hares and Grouse) and the lowest in rabbits feeding on grass over mineral soils. Radiocaesium was found in a carnivore (the fox) at the top of the food chain. (author)

  4. 10th anniversary of Chernobyl

    Every issue has its defining event. There is no doubt that the single word which now embodies that difficult-to express unease felt by many people about nuclear power is Chernobyl. In this sense, April 26 1996 will be far more than an anniversary, just as Chernobyl was far more than a very serious accident which was nonetheless largely localised in its effects. It will be used by those who wish to the industry - the professional campaigners in the Green movement - and those who see an opportunity to sell newspapers or TV programmes - the professional exaggerators - to spread that unease as far as possible. The British Nuclear Industry Forum, which consists of seventy member companies at the heart of nuclear power in the UK, has convened a Task Force, with an international membership, in an attempt to make sure that we are ready for the anniversary, and to respond to the tactics of the opposition in as effective a way as possible. This paper outlines the general principles which have so far emerged from our discussions. There are two guiding principles to our approach. The first is that no matter how good a story is about Chernobyl, it is still a bad story. But secondly, this anniversary will be big news whether we like it or not, so we must make the best of it. In this sense the event brings with it opportunities to remind people of positive messages, on fuel diversity, on environment, and on Western efforts to help to improve the safety standards of the nuclear industry in the region, and the health of the people near Chernobyl. This leads to a position for the campaign which might appear paradoxical. We must be proactive but low-profile. We simply cannot afford to keep quiet and let the wildest claims about the effects of Chernobyl be spouted unchallenged. This does not simply mean generating responses to stories once they have been published. It means analysing press coverage of previous anniversaries to understand how the media are likely to treat it; it means

  5. An ill wind from Chernobyl

    This article discusses the effects that the poisonous dust emanating from the Chernobyl nuclear reactor explosion of 1986 had on human, animal and plant population in the Soviet Union and across Europe. One of the chief criticisms raised is of governments, inside and outside the Soviet Block restricting information about danger to people or, in some cases, denying any consequences. This has led to widespread public opinion against nuclear programmes for power generation, and calls for adequate and appropriate compensation for victims of the accident. (UK)

  7. Chernobyl record. The definitive history of the Chernobyl catastrophe

    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 131I, and the contamination of other parts of the food chain by 137Cs. Chapters 12-14 describe the environmental impact of the accident, as does chapter 11.

  9. Health effects of the Chernobyl accident and special health care programmes. Report of the UN Chernobyl Forum Expert Group 'Health'

    Twenty years have passed since the worst nuclear reactor accident in the world occurred at the Chernobyl nuclear power plant in Ukraine. The radioactive contamination which resulted from the explosion and fire in the first few days spread over large areas of neighbouring Belarus and the Russian Federation, with most of the fallout in Belarus. While national and local authorities did not immediately disclose the scale of the accident, the mitigation measures, such as distribution of potassium iodine pills, food restriction, and mass evacuation from areas where the radioactive contamination was greatest, undoubtedly reduced the health impact of the radiation exposure and saved many lives. The accident caused severe social and economic disruption and had significant environmental and health impact. This was aggravated by the political and economical changes in the three affected states related to the break-down of the Soviet Union. In the aftermath of the accident the international scientific and medical community collaborated closely with national experts dealing with health effects of the accident in the affected countries. There is a substantial body of international collaborative projects on the situation, which should lead to advancement in radiation sciences. However, considerable speculation and disinformation remains about the possible health impact of the accident for the millions of affected people. To address the health, environmental and socioeconomic consequences of the Chernobyl accident, the United Nations in 2003 launched an Inter-Agency initiative, the Chernobyl Forum. The Forum's Secretariat, led by the International Atomic Energy Agency (IAEA), the World Health Organization (WHO), the United Nations Development Programme (UNDP), and several other international organizations collaborated with the governments of the affected countries. The purpose of the Chernobyl Forum was to review the consequences of the accident, issue technical reports and, based

  10. Chernobyl: Anatomy of the explosion

    On Friday, 26 April 1986, it was planned to shut down the fourth unit of the Chernobyl Atomic Power Station, U.S.S.R., for periodic maintenance. The procedure supplied the opportunity to perform a further experiment; operation of the turbine in free rotation regime, which occurs when the steam is cut down while the turbine is still running. It so happened that carrying out this experiment turned out to be the worst accident in the history of nuclear power industry. The first part of the article proceeds to a second by second detailed analysis of the causes of the catastrophe. The analysis uses official data and reports. The author covers the sequence of events, which led up to two explosions in the second hour of that tragic morning. In the second part of the article, the author provides hints and suggestions, so that 'the tragedy of Chernobyl does not become a useless lesson'. With regard to what, so far, has been published, the novelty of the article may be a diagram showing the excessive changes that affected the main parameters (power, water flow through circulating pumps, steam pressure in separators, and length of the immersed part of control rods) in the fourth unit during the last seconds before the explosion. If may be noteworthy to mention that the curves supplied here are based on data stored in the computer 'SCALA'. 2 figs

  11. Impressions of Chelyabinsk and Chernobyl

    An international delegation touring Russia and Ukraine was demonstrated the consequences of the accidents at the nuclear installations of Chelvabinsk and Chernobyl. On the site in Russia, an explosion of a tank filled with high level radioactive waste in 1957 released a radioactive cloud of approx. 20 million Ci, of which 90% rained down in the immediate vicinity, while 10% spread over an area of 23,000 square kilometers. 10,200 persons were resettled for this reason within two years. Among the population in the contaminated area, the cancer rate rose, but is still said to be lower than at other industrialized sites. At a distance of 44 km from the Chernobyl nuclear power plants, the new city of Pripyat has been established for 23,000 inhabitants. Planning work on additional nuclear generating units was stopped after the accident of unit 4. The complete loss of unit 4 has been felt by the USSR as a bigger economic disaster than the radioactive contamination of the environment. (orig.)

  12. Genetic effects of the Chernobyl accident

    Genetic radiation effects resulted from the Chernobyl accident were considered for the population of Russia, Ukraine and Belarus. Techniques of the assessment of genetic risk of exposure of a man was discussed. Results of cytogenetic examination of the population were presented as well as health state of pregnants and newborns following the Chernobyl accident. Elevated level of chromosomal aberrations in lymphocytes of peripheric blood in participants of the Chernobyl accident response and in population of contaminated zones. This fact testifies on the real genetic injury in cells due to accident. Growth of intrauterine losses in pregnancy, congenital anomalies, hereditary diseases in descendants of exposed parents. 17 figs

  13. Malignant neoplasms on the territories of Russia damaged owing to the Chernobyl accident

    The work presents the results of descriptive analysis of development of onco epidemiological situation in six of the most polluted regions owing to the Chernobyl accident in 1981-1994. The growth of malignancies incidence is marked in all territories as well as in the Russian Federation as a whole. The most adverse tendencies have been revealed in the Bryansk, Orel, Ryazan regions. It is marked that the formation of a structure, levels and trends of the malignancies incidence has been occurring under influence of a complex of factors usual up to the accident. The analysis of the data from the specialized cancer-register evidences that the incidence of thyroid malignancies is actively growing in the population of the Bryansk region. The probability of connection of growth of the thyroid cancer incidence in children of the Bryansk region with the Chernobyl accident is reasonably high, but should be confirmed through the application of methods of analytical epidemiology

    2006-06-15

    26 April 2006 marks the 20th anniversary of the Chernobyl accident. On this occasion, the World Health Organization (WHO), within the UN Chernobyl Forum initiative, convened an Expert Group to evaluate the health impacts of Chernobyl. This paper summarises the findings relating to cancer. A dramatic increase in the incidence of thyroid cancer has been observed among those exposed to radioactive iodines in childhood and adolescence in the most contaminated territories. Iodine deficiency may have increased the risk of developing thyroid cancer following exposure to radioactive iodines, while prolonged stable iodine supplementation in the years after exposure may reduce this risk. Although increases in rates of other cancers have been reported, much of these increases appear to be due to other factors, including improvements in registration, reporting and diagnosis. Studies are few, however, and have methodological limitations. Further, because most radiation-related solid cancers continue to occur decades after exposure and because only 20 years have passed since the accident, it is too early to evaluate the full radiological impact of the accident. Apart from the large increase in thyroid cancer incidence in young people, there are at present no clearly demonstrated radiation-related increases in cancer risk. This should not, however, be interpreted to mean that no increase has in fact occurred: based on the experience of other populations exposed to ionising radiation, a small increase in the relative risk of cancer is expected, even at the low to moderate doses received. Although it is expected that epidemiological studies will have difficulty identifying such a risk, it may nevertheless translate into a substantial number of radiation-related cancer cases in the future, given the very large number of individuals exposed.

  18. The ecology of the Chernobyl catastrophe. Scientific outlines of an international programme of collaborative research

    The Chernobyl disaster was the largest civil nuclear catastrophe of all time. When reactor number 4 of the Chernobyl nuclear power plant exploded on 26 April 1986, it permanently changed the lives of more than 4 million people living in Belarus, Ukraine and Russia, shaking the fabric of an area almost the size of England, and triggering a whole swathe of environmental, economic, social, medical and political repercussions. At first the Soviet Union tackled the aftermath alone but, by 1990, with the process of change associated with perestroika, the three affected states of Belarus, Ukraine and the Federation of Russia appealed to the international community for solidarity and help. In co-operation with other agencies of the United Nations system, the UNESCO Chernobyl Programme was launched , with the formal signing of an agreement in January 1991 between the three republics and UNESCO. Since then, some twenty projects have been carried out in UNESCO's various fields of competence - education, science, culture and communication. The volume reviews eight years of study on the impact of Chernobyl on natural ecosystems, agro-ecosystems, human ecology, biological diversity, and genetic and socio-economic systems. It comprises eight chapters. The first three chapters discuss the effects of the high levels of radionuclides released from the Chernobyl reactor on the environment, on natural ecosystems and on agro-ecosystems. The fourth chapter, on human ecology, covers both the human effects at the time of the disaster and those still continuing today. Chapters five and six describe the impact of radionuclide release on biological diversity and genetic systems respectively. The socioeconomic effects of the catastrophe are discussed in chapter seven. Each of these seven chapters ends with scientific hypotheses and research recommendations, with a final chapter providing a detailed description of the setting up and aims of the multinational and multidimensional Chernobyl

  19. Alpha emitters in Chernobyl hot particles

    The alpha radioactive component of hot particles from the Chernobyl fallout was analysed for cases studied previously by gamma spectroscopy. Correlations established from the absolute alpha activity determination and high resolution analysis provided information on actinides release during accident and on some aspects of the Chernobyl reactor fuel composition. Unexpected features revealed during the analysis of one specific particle are presented. 11 refs., 5 figs., 5 tabs. (author)

  20. Migration of Chernobyl plutonium in soils

    Various geochemically linked landscapes were studied for the distribution of Chernobyl plutonium in soils. Significant behaviour of the Chernobyl plutonium may be observed only in case of its fall out with finely dispersed fuel. Within the areas polluted with the volatile ejection products, the plutonium migration forecast may be based on previous estimations obtained for the forest and forest-steppe zones.

    The alpha radioactive component of hot particles from the Chernobyl fallout was analyzed for cases studied previously by gamma spectroscopy. Correlations established from the absolute alpha activity determination and high resolution analysis provided information on the release of actinides during the accident and on some aspects of the Chernobyl reactor fuel composition. Unexpected features revealed during the analysis of one specific particle are presented. (orig.).

  3. Radiation effects blamed on Chernobyl

    Strictly speaking, the nature of an epidemiological study would not permit the same causal links to be established as an experimental study does. Instead, it merely provides circumstantial evidence, from which some conclusions can be drawn as to the causative factors in the occurrences recorded. To summarize it may be stated that as fas as the Germans are concerned no scientific evidence has so far been provided to prove health impairments attributable to an added radiation load from the Chernobyl fallout. On the other hand, it can not be denied that there are indications of health damage in a few individuals unreasonably changing their eating habits for fear of radiation injuries. The question as to whether the event instilled a permanent feeling of unease in some population groups still remains largely obscure. (orig.)

  4. Chernobyl - state of the art

    This article aims to analyze what has been done so far in relation to damage caused by the accident and the state of art in Chernobyl, as well as the impact on radiation protection applied safety nuclear power plants. In the first part of the work a data survey was done through a bibliographic review and the in the second part data was collected during a visit, in June 2013 at the crash site, when was observed dose values in the affected areas and the works of repairs that have been made in the sarcophagus and surroundings as well as in official reports available through active international bodies. The main results indicate significant improvements in radiation protection systems

  5. Summary of Chernobyl followup research activities

    In NUREG-1251, ''Implications of the Accident at Chernobyl for Safety Regulation of Commercial Nuclear Power Plants in the United States,'' April 1989, the NRC staff concluded that no immediate changes in NRC's regulations regarding design or operation of US commercial reactors were needed; however, it recommended that certain issues be considered further. NRC's Chernobyl followup research program consisted of the research tasks undertaken in response to the recommendations in NUREG-1251. It included 23 tasks that addressed potential lessons to be learned from the Chernobyl accident. This report presents summaries of NRC's Chernobyl followup research tasks. For each task, the Chernobyl-related issues are indicated, the work is described, and the staff's findings and conclusions are presented. More detailed reports concerning the work are referenced where applicable. This report closes out NRC's Chernobyl followup research program as such, but additional research will be conducted on some issues as needed. The report includes remarks concerning significant further activity with respect to the issues addressed

  6. Chernobyl reactor accident: medical management

    Chernobyl reactor accident on 26th April, 1986 is by far the worst radiation accident in the history of the nuclear industry. Nearly 500 plant personnel and rescue workers received doses varying from 1-16 Gy. Acute radiation syndrome (ARS) was seen only in the plant personnel. 499 individuals were screened for ARS symptoms like nausea, vomitting, diarrhoea and fever. Complete blood examination was done which showed initial granulocytosis followed by granulocytopenia and lymphocytopenia. Cytogenetic examinations were confirmatory in classifying the patients on the basis of the doses received. Two hundred and thirty seven cases of ARS were hospitalised in the first 24-36 hrs. No member of general public suffered from ARS. There were two immediate deaths and subsequently 28 died in hospital and one of the cases died due to myocardial infarction, making a total of 31 deaths. The majority of fatal cases had whole body doses of about 6 Gy, besides extensive skin burns. Two cases of radiation burns had thermal burns also. Treatment of ARS consisted of isolation, barrier nursing, replacement therapy with fluid electrolytes, platelets and RBC transfusions and antibiotic therapy for bacterial, fungal and viral infections. Bone marrow transplantations were given to 13 cases out of which 11 died due to various causes. Radiation burns due to beta, gamma radiations were seen in 56 cases and treated with dressings, surgical excision, skin grafting and amputation. Oropharangeal syndrome, producing extensive mucous in the oropharynx, was first seen in Chernobyl. The patients were treated with saline wash of the mouth. The patients who had radioactive contamination due to radioactive iodine were given stable iodine, following wash with soap, water and monitored. Fourteen survivors died subsequently due to other causes. Late health effects seen so far include excess of thyroid cancer in the children and psychological disorders due to stress. No excess leukemia has been reported so

  7. Chernobyl accident. Exposures and effects

    The Chernobyl accident that occurred in Ukraine in April 1986 happened during an experimental test of the electrical control system as the reactor was being shut down for routine maintenance. The operators, in violation of safety regulations, had switched off important control systems and allowed the reactor to reach unstable, low-power conditions. A sudden power surge caused a steam explosion that ruptured the reactor vessel and allowed further violent fuel-steam interactions that destroyed the reactor and the reactor building. The Chernobyl accident was the most serious to have ever occurred in the nuclear power industry. The accident caused the early death of 30 power plant employees and fire fighters and resulted in widespread radioactive contamination in areas of Belarus, the Russian Federation, and Ukraine inhabited by several million people. Radionuclides released from the reactor that caused exposure of individuals were mainly iodine-131, caesium-134 and caesium-137. Iodine-131 has a short radioactive half-life (8 days), but it can be transferred relatively rapidly through milk and leafy vegetables to humans. Iodine becomes localized in the thyroid gland. For reasons of intake of these foods, size of thyroid gland and metabolism, the thyroid doses are usually greater to infants and children than to adults. The isotopes of caesium have relatively long half-lives (caesium-134: 2 years; caesium-137: 30 years). These radionuclides cause long-term exposures through the ingestion pathway and from external exposure to these radionuclides deposited on the ground. In addition to radiation exposure, the accident caused long-term changes in the lives of people living in the contaminated regions, since measures intended to limit radiation doses included resettlements, changes in food supplies, and restrictions in activities of individuals and families. These changes were accompanied by major economic, social and political changes in the affected countries resulting

    The fear of radiations reinforced by terrifying stories in newspapers and unqualified policies has provoked a great number of psychosomatic illness in the area of Chernobyl. A specialist of radiations reviews the situation and takes to pieces the wrong presuppositions of radiations monitoring agencies. (N.C.)

  9. Chernobyl

    This report relates the Chernobylsk accident, why following a succession of technical malfunctions and human errors, reactor no. 4 of the Chernobylsk nuclear power plant explodes on April 26. 1986. Radioactive dust, aerosols and gases (including caesium and iodine) are ejected into atmosphere. The regions worst hit are in the immediate vicinity of the plant, but deposits are very uneven, producing a leopard spot type of pattern. Propelled by easterly winds, the radioactive cloud disperses increasingly, scattering deposits over the whole of Europe. At the beginning of May, the cloud arrives in France. the eastern portion of the country is most strongly affected. Ground, water and agriculture are contaminated by caesium deposits in Belarus, Ukraine and Russian Federation. About the contamination in France, ground contamination is slight, fourteen years later, however, it is still detectable. Relative to the impact on health in the vicinity of Chernobylsk plant, it is hard to assess this impact. Among children in Southern Belarus, the number of thyroid cancers has risen one hundred-fold. In France, the doses delivered represents 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 provided for december 2000. (N.C.)

  10. Psychosocial consequences of the Chernobyl disaster (A survey of Chernobyl accidental exposed and a non-exposed population sample)

    The importance of psychological factors in the aftermath of industrial disasters is being recognized increasingly. Two field studies (total N=3084) were conducted in two regions of the former Soviet Union, to investigate the long-term psychosocial consequences of the Chernobyl nuclear power plant disaster in 1986. A sub sample of the respondents (N=449) was studied using a standardized physical and psychiatric examination. The first study took place in the Gomel region (Belarus) in the direct vicinity of the damaged nuclear plant. A control study was conducted in the Tver region (the Russian Federation), about 250 km north-west of Moscow. The results of the study indicate significantly higher levels of psychological distress, poorer subjective health and higher medical consumption in the exposed population. These findings were most prominent in risk groups such as evacuated people and mothers with children. No significant differences in overall levels of psychiatric or physical morbidity were found. Radiation related diseases could not account for the poor health perception in the investigated sample. These results indicate that psychological factors following the Chernobyl disaster had a marked effect upon psychological well being, on perceived health and on subsequent illness behavior. Fears about future health play a key role in determining this response. The provision of adequate information to the public as well as to the public health services may be important to counteract these fears

  11. Stakeholders and radiological protection: lessons from Chernobyl 20 years after

    Twenty years after the major accident at the Chernobyl nuclear power plant, the radioactive contamination continues to have an important impact on lives in the vicinity, and to a lesser extent in areas such as Western Europe and beyond. The purpose of this report is not to address clinical or environmental studies, but to look at how people are coping with the difficulties they still face. Commissioned by the Committee for Radiation Protection and Public Health of the OECD Nuclear Energy Agency (NEA), the report focuses on the role of radiological protection and how this discipline has been deployed to help people manage their lives. Although the topic of this report concerns radioactivity and nuclear power, it can also be very useful to policy makers and experts dealing with the aftermath of wide-scale disasters, regardless of their causes (natural, accidental or malicious). Whilst we all hope never to see another event causing contamination on the scale that followed Chernobyl, it is prudent to be prepared. Hence this report also describes many of the problems that could need to be faced in the longer term by technical specialists, should such a contamination event occur, and presents ways of dealing with them. This report will provide readers with insights into how to plan better for this type of event, in particular beyond the immediate response phase. (author)

  12. DDG-NS statement at the opening of the international conference 'Chernobyl: Looking back to go forwards'

    The IAEA, as a specialised nuclear-related technical UN agency, has been involved in the mitigation of the Chernobyl accident consequences since early May 1986 when former Director General Hans Blix had visited Chernobyl in order to observe the physical damage and to discuss further actions. The IAEA took on many projects related to technical assistance, technical co-operation and research - with several immediate and longer term goals: first, to mitigate the accident's radiological, environmental and health consequences; second, to improve the overall safety of other RBMK reactors; and third, to understand and disseminate globally those lessons that could be learned from the Chernobyl experience. The projects executed between 1986 and 2005 covered the full range of topics: radiation, waste and nuclear safety; monitoring human exposure; environmental restoration of contaminated land; treatment of people living in the affected areas; and development of special measures to reduce exposure levels. The largest project took place in 1990. Over a two year period, the Agency coordinated the efforts of some 200 international experts over a two year period to complete an independent assessment of the consequences of the Chernobyl accident. Many missions to the three most affected countries were conducted and many meetings were held. The Agency has also organized or supported numerous international meetings to foster information exchange and to promote further assessment of the accident's radiological consequences. The Agency continues its ongoing activities regarding the mitigation of the accident's radiological consequences as part of the UN strategy 'Human Consequences of the Chernobyl Accident - A Strategy for Recovery' launched in 2002. Further IAEA commitment in continued Chernobyl-related activities, mainly in nuclear and radiation safety fields, may involve the following areas: Safety of Shelter decommissioning, Safety of radioactive waste management in the Chernobyl

  13. Chernobyl information: The ALARA backlash

    The risk information to the public failed after the Chernobyl accident, also in countries where radiation protection authorities and experts initially enjoyed public confidence. In contrast to many other large accidents, the responsibility for the information failure stays mainly with the authorities and experts themselves, not with the mass media. Many factors together caused the radiation risk information from SSI (Swedish Radiation Protection Institute), and its sister authorities in many other countries, to be confusing and inadequate, despite the best of intentions. The two major malefactors were the handling of food contamination restrictions and the short-sighted risk optimisation by applying the ALARA principle. In addition, the assurance that the Chernobyl contamination was fairly harmless made no sense to the layman, as a massive array of controlling procedures was enforced simultaneously. The food regulations became unfortunately focused on becquerel per kilogram limits instead of the primary goal, a dose reduction per year, corresponding to an yearly intake of Cs-137. The lesson learned is that the risk significant long-term intake ambition must be understood and digested by laymen and media, before any secondary limits, e.g. the activity concentration of foodstuffs expressed as becquerel per kg, for controlling or trading purposes, are introduced. As it were, the experts and authorities lost credibility, due to what people considered as ambiguities. The concept of ALARA (As Low As Readily Achievable) is in the backbone of every ionising radiation expert, and a useful strategy for optimising dose burdens during controlled situations. In connection to the Chernobyl accident many advices to the public was given based on the ALARA principle. 'Rinse leafy vegetables' sounds at first very reasonable, cheap and innocent, but if the averted dose is low, such an advice should not be given. The individual dose-reduction should be weighted against all negative

  14. Chernobyl from the point of view of disaster sociology

    Some social aspects of the Chernobyl accident for Belarus are considered. The information system of publications on this theme is analyzed. The influence of various factors of the Chernobyl accident on social changes in the areas of radioactive contamination is investigated. The Chernobyl subculture formation process in the contaminated areas is considered. Practical recommendations of sociologists on the elimination of the Chernobyl catastrophe effects are given. 12 refs

  15. Chernobyl after five years and over

    On April 26th 1986 the catastrophe occurred at the nuclear electric power generation system. The first inkling of the accident was known through the Swedish monitoring station about the radioactive fallout. It was also in 1986 that the USSR gave an idea of an earlier accident which happened in 1957. The Chernobyl reactor has pressure tubes and is a pressure vessel reactor. Graphite is used as an industrial material. In western reactors in USA with the increase in heat, power generation comes down. The international AEC discussed the Chernobyl comprehensively and came out with conclusion of deficiency in design which was accepted by the Soviet side without any demur. In 1970, in UK an accident has been reported with pressurized reactor. In 1987, Chernobyl was discussed under the chair of Eugene Volkov by USSR. In 1989, another conference was arranged at Sicily. The first annual nuclear safety met at Minsk in 1990 (June); USSR/USA meet on Chernobyl was also held at Solchin in 1989. A future meeting on Chernobyl was held at Paris in July 1991. In all these meetings, it is emphasized that more training and safety culture establishment was necessary by the international nuclear safety advisory group on safety. (author). 2 refs., 1 tab

  16. Radionuclide migration in the Chernobyl contamination zone

    It is well known that the Chernobyl fallout of 137 reaching the land soils with precipitation was rapidly and tightly sorbed to the fine fraction of sediment or soils. The majority of the 137Cs is retained in the top few centimetres of the soil or sediment profiles. In the absence of strong variations in precipitation over a relatively small area the total bomb-derived 137Cs fallout can assumed to be spatial uniform. The Chernobyl 137Cs fallout was mostly connected with one or two rains. So the spatial variability of this 137Cs can be higher. Furthermore because the explosion of the Chernobyl nuclear plant happened together with fire lot of ashes particles with radionuclide were distributed within vast areas. So even microvariability of Chernobyl 137Cs can be very high in some places. The horizontal migration of 137Cs connects with soil erosion processes that dominate on the agricultural lands of the Central Russia. The main goal of this investigation is to evaluate the caesium-137 horizontal and vertical migration within typical landscape of the Central Russia 11 years after the Chernobyl accident.

    Radioactive contamination after the Chernobyl (1986) and Fukushima (2011) accidents is a multi-disciplinary geoscience problem. Just this session (GI1.4) contains presentations of (i) atmospheric transport for both short and long distances, (ii) aerosol physics and chemistry, (ii) geophysical measurement method and logistics, (iv) inversion method to estimate the geophysical source term and decay, (v) transport, migration, and sedimentation in the surface water system, (vi) transport and sedimentation in the ocean, (vii) soil chemistry and physics, (viii) forest ecosystem, (ix) risk assessments, which are inter-related to each other. Because of rareness of a severe accident like Chernobyl and Fukushima, the Chernobyl's 27 years experience is the only knowledgebase that provides a good guidance for the Fukushima case in understanding the physical/chemical processes related to the environmental radioactive contamination and in providing future prospectives, e.g., what we should do next for the observation/remediation. Unfortunately, the multi-disciplinary nature of the radioactive contamination problem makes it very difficult for a single scientist to obtain the overview of all geoscientific aspects of the Chernobyl experience. The aim of this introductory talk is to give a comprehensive knowledge of the wide geoscientific aspects of the Chernobyl contamination to Fukushima-related geoscience community.

  18. Medical consequences of Chernobyl accident

    Galstyan I.A.

    2015-12-01

    Full Text Available Aim: to study the long-term effects of acute radiation syndrome (ARS, developed at the victims of the Chernobyl accident. 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.

  19. Chernobyl. Disaster and its legacy

    Hundreds of thousands of people have been helping to mitigate the consequences of the Chernobyl reactor accident, but there still are many areas in which many people have to live with the risks induced by elevated environmental radioactivity. The authors of the book have been participating in the measuring programme of the Federal Republic of Germany, intended to measure and map the radiation exposure of the population and the environment in the states of the former Soviet Union affected by the disaster. Due to their participation in biophysical and medical measuring programmes, the authors are familiar with the situation on site. Their report is intended to give the general reader a picture of the causes and progress of the reactor accident of April 1986, and of its longlasting effects on human health and the food chain. The information presented is based on authentic material and data and reveals the biologic, medical and social consequences as well as the related scientific and ecologic problems. (orig./HP)

  20. Phytoremediation of Chernobyl Contaminated Land

    Most of the land within a 10 km radius of the Chernobyl Nuclear Plant is still heavily contaminated by the 1986 accident. In 1998, a 3 year investigation of the potential of willow vegetation systems to stabilise the contaminated land and thereby reduce the dispersion of radionuclides was initiated under the PHYTOR project. During the first year, a number of screening tests were carried out on the contaminated flood plain of the river Pripyat. Survival of new willow plantations was tested at several locations. Except for the predominantly moist peaty soil in the vicinity of Yanov (where survival was nearly 100%), survival was low (0-30%). Notwithstanding, willows are found everywhere on the Pripyat flood plains: 7-8 year old plantations exist on the upper terraces and 1-2 year old saplings cover the newly deposited alluvial sands. For these willows radiocaesium transfer factors ranged from 10-4 and 10-3 m2.kg-1 and strontium transfer factors from 10-3 and 10-2 m2.kg-1. Biomass production was low: 70-100 kg.ha-1.y-1. Therefore, the radionuclide immobilisation in the biomass was insignificant. Even when based on the exchangeable caesium fraction, less then 0.1% for radiocaesium and less than 1% for radiostrontium became incorporated into the wood. Nevertheless, establishment of willow would reduce resuspension and erosion of soil and sediment. (author)

  1. Leukaemia incidents after Chernobyl accident

    Romania and especially its Eastern territory were among the most heavily affected area after Chernobyl accident. The objective of our study was to investigate whether or not the nuclear accident determined an increased number of leukaemia cases. The specific rates of leukaemia incidents by age group were calculated in 588167 children aged 0-6 years in April 1986 and 99917 children which have been exposed 'in utero'. The rates of 1989-1994 period were compared with the rates of 1980-1985 period. The incidence rates were lower in the exposed group than that in controls for children under 1 year (20.52/105 inh vs 23.11/105 inh), 1-3 years (13.26/105 inh vs 16.11/105 inh) and 4-6 years (9.58/105 inh vs 10.58/105 inh). The cohort of 'in utero' exposed children presented a leukaemia incidences insignificantly higher than that before the accident (23.10/105 inh vs 15.93/105 inh)

  2. Chernobyl - ethical and environmental considerations

    The paper summarises briefly the main facts of the Chernobyl incident, the reactions to it, and the consequences in terms of global atmospheric pollution. Meteorological conditions determined the pattern of fallout, which over the United Kingdom for Cs137 varied in the ratio 10 : 4000 Bq/m2 (on grass). There has been poor understanding by the media and the public of the quantitative aspects, aggravated by the differing characteristics of the several radionuclides (15 are listed), and the different units used in the USSR and the UK. Very complete information on fallout in the British Isles was obtained from meteorological data and the atmospheric dispersion models operated at Imperial College. Transfer through food chains depended on the variety of circumstances: the monitoring programmes and control measures were found to be in need of improvement, as no criteria existed for the amounts that justify intervention in the supply of foodstuffs to the public. Long-term effects in the UK of the measured radiation from this incident, in terms of deaths per year attributed to cancer are given and compared with other health hazards. The disaster has underlined the responsibilities of top management and of professional engineers, the need to promote a 'safety culture', and the value of effective organisation, the international exchange of experience, and the role of the media in improving public information.

  3. Laser marking method and laser marking device

    For distinguishable control for members such as fuel rods while following after the flow of transportation/storage/utilization, it is necessary to apply marking directly to cladding tubes. However, in a marking method for using letter pattern-masking, it is necessary to prepare and exchange various kinds of letter pattern masking corresponding to the marking letters, and the marking operation is not efficient. Then, laser beams are irradiated under focussing on the surface of an object, and the laser beams are scanned while being controlled to oxidize the surface of the object thereby applying bar code-like markings. The surface of the object at the periphery of the starting point of the laser beam scanning is coated with a mask having a predetermined thickness to conduct marking. The device can be simplified, the marking operation can be improved, occurrence of fine pores so called spikes can be prevented previously, and melting damage of the mask can be prevented since the laser beams are not focused on the surface of the mask.

  4. Scientific and technical aspects of Chernobyl

    The collection contains the presentations and scientific articles prepared for and discussed during the Conference titled '2001: International Cooperation For Chernobyl'. The materials outline the outcomes achieved while implementing Chernobyl site scientific-technical researches and projects, as well as activities aimed at enhancing the ChNPP safety, decommissioning and radwaste management. It also highlights the issues related to transforming the Unit Shelter into an ecologically safe system, represents the results of ecological researches in the Exclusion Zone, medical effects of the 1986 accident at Chernobyl NPP, together with social and economic problems the city of Slavutich faces now due to the early ChNPP Units decommissioning, and Slavutich business development opportunities under the circumstances of Special Economic Zone 'Slavutich'

  5. Post-Chernobyl scientific perspectives: Thyroid effects

    The population in the area around Chernobyl, particularly southern Belarus and northern Ukraine, was exposed to high levels of fallout from the Chernobyl accident including large amounts of radioactive iodine. As the thyroid gland concentrates iodine, it was exposed to higher levels of radiation than other body tissues. The radioactive isotope of iodine, iodine-131, has been extensively and safely used in the treatment of thyrotoxicosis. Thus, the report of increased numbers of thyroid carcinoma in children in areas exposed to fallout from Chernobyl was surprising to some, both because of the previous lack of thyroid carcinoma in patients treated with radioactive iodine, and because of the very short time (four years) between exposure and the start of the increase

  6. The international Chernobyl project: Assessment of radiological consequences and evaluation of protective measures

    This brochure gives a brief account of the findings of the International Chernobyl Project. Further details will be found in the report ''The International Chernobyl Project: An Overview'' (INI22:066284/5) and in the Technical Report (INI23:011339). Measurements and assessments carried out under the project provided general corroboration of the levels of surface cesium-137 contamination reported in the official maps. The project also concluded that the official procedures for estimating radiation doses to the population were scientifically sound, although they generally resulted in overestimates of two- to threefold. The project could find no marked increase in the incidence of leukemia or cancer, but reported absorbed thyroid doses in children might lead to a statistically detectable rise in the incidence of thyroid tumors. Significant non-radiation-related health disorders were found, and the accident had substantial psychological consequences in terms of anxiety and stress

  7. Latest report about health effects of the chernobyl accident

    After twenty years of Chernobyl accident, the international conference was hold in Kyiv, Ukraine, 24-26, April in 2006. During the conference WHO declares the paper named health effects of the Chernobyl accident. The report look back the nuclear accident in the history, and then recite conclusion about health effects of the Chernobyl accident, which from doses received from the Chernobyl accident, thyroid cancer, non-thyroid solid cancer, leukemia, mortality, cataract and cardiovascular disease. The report is considered as milestone events in the studying of health effects of Chernobyl accident. (authors)

  8. The Chernobyl disaster - ten years on

    Large areas of Belarus, Russia and the Ukraine are contaminated with very high levels of radioactivity from the fallout of the Chernobyl reactor accident. The most affected areas are in the vicinity of Chernobyl, and east of Gomel (in Belarus), where much of the radioactive plume came down. The article describes the contamination with cesium 137 and iodine 131, as well as the immediate countermeasures taken after the accident, and the long-term action for decontamination of the polluted soil. Information is given on the radiation dose received by the population, in particular the thyroid doses, and prognostic data on thyroid cancer incidence. (orig.)

  9. The Nordic Chernobyl data base project

    Chernobyl Data Base has been established with the purpose of collecting the large amount of data resulting from measurements made in several laboratories in the period following the Chernobyl accident. All information is stored in the C data base handling system developed especially for this kind of environmental data. The C base data handling system allows for easy input from a variety of sources and easy output to other computer programs for further data treatment. This paper describes the structures, codes and methods used and the present status of the project. (au)

  10. Consequences and problems of the Chernobyl accident

    The data on epidemic situation in connection with the Chernobyl accident, based on the personal medical and dosimetric information on all the persons, subjected to radiation effect, and included in the Russian state medicodosimetric register, are presented. The consequences of the Chernobyl accident become the cause for origination of serious radiation injures by 134 persons (with lethal outcome by 37 patients) and also remote radiation stochastic effects by children (thyroid gland cancer) and by liquidators (thyroid gland leucosis and cancer). The permanent stress and other unfavorable factors conditioned aggravation of chronical and increase in somatic diseases and psychoneurotic disorders

  11. Chernobyl birds have smaller brains.

    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.

    The IAEA have co-ordinated the first international assessment of the radiological consequences of the Chernobyl accident in the affected areas outside the 30km prohibited zone around the reactor. These areas have a total population of about 1 million people, living in approximately 2700 settlements. The main aim of the project was to answer the question 'Is it safe for the population to go on living in the affected areas?'. The project did not investigate radiological health effects among more than 100 000 people evacuated from the 30 km prohibited zone. Nor did it study effects among the emergency personnel temporarily brought into the region for accident management and recovery work (the so-called 'liquidators'). Project teams reviewed official data on environmental contamination from 500 settlements, data collection practices and reporting and also official information on radiation doses received by people living in seven settlements. Other project teams reviewed official data at key medical centres and institutes. Then they examined people both from surveyed contaminated settlement and from surveyed control settlements. The team concluded that there were significant non-radiation related health disorders in populations of both contaminated and control settlements. None of the disorders could be attributed directly to radiation exposure. In particular, no evidence was found for a significant increase in foetal abnormalities; infant and prenatal mortality rates had fallen since the accident. Children were found to be generally healthy with no abnormalities in either thyroid stimulating or thyroid hormones. The accident had created substantial negative psychological consequences, manifesting themselves in terms of anxiety and stress due to continuing high levels of uncertainty. (author)

Today in the practice there are many different methods that could be used to realise high quality on the workpiece of various materials with various shapes. Some materials could be marked only by marking or engraving without special requirements and difficulty, while for other materials one can choose the concrete method about the kind of material, marking type, and the specific needs of the production process an...

  14. Fallout from Chernobyl and atmospheric nuclear weapons tests. Chernobyl in perspective

    Some results and experience gained so far in Sweden after the Chernobyl accident are discussed in the light of knowledge obtained from the studies of fallout from the atmospheric nuclear weapons tests. Cesium-137, which was an important radionuclide in the bomb fallout, was still more important after Chernobyl. For most Swedes the external irradiation from deposited Cs-137 was the dominating source of irradiation. Studies of Chernobyl fallout have given new information in the fate of contamination in the forest environment, lakes, urban areas, on shielding factors for houses etc. The releases from Chernobyl gave relatively lower dietary doses than expected form the same amount of Cs-137, released through nuclear weapons testing. However lake fish, moose and forest products have shown to be of greater importance than earlier realized. The main reason for the lower dietary doses from Chernobyl was the seasonal distribution of the fallout with deposition just before the start of the growing season. The various actions taken also reduced the intake of Cs-137 and Cs-134. Otherwise, there are no radical differences in the behaviour of cesium in the environment after the bombs and after Chernobyl. Differences may exist, primarily during the first year, due to different fallout conditions, where also the physical-chemical form of the fallout might have been of some importance. The average Swede will have an effective dose commitment of around 1 mSv from Chernobyl, which is about the same as from the bomb fallout. The highest doses due to Chernobyl area received by people living in high deposition areas (>80 kBq/m2 of CS-137) and consuming larger amounts of game animals, lake fish and reindeer. (66 refs.)

  16. Health consequences of the Chernobyl accident. Results from the IPHECA pilot projects and related national programmes. Summary report from WHO 1995

    The main conclusions drawn from the investigations are that the Chernobyl accident caused psychosocial problems due to poor information just after the accident, and stresses and traumas inter alia due to forced relocation. A marked increase of thyroid cancer among children has been demonstrated. However, no significant increase in the frequency of leukemia has been observed., 2 figs, 3 tabs

  17. One decade after Chernobyl. Summing up the consequences of the accident. Proceedings of an international conference

    The consequences attributed to the disastrous accident that occurred at the Chernobyl nuclear power plant on 26 April 1986 have been subjected to extensive scientific examination; however, they are still viewed with widely differing perspectives. It is fitting then that, ten years after the accident, the European Commission (EC), the International Atomic Energy Agency (IAEA) and the World Health Organization (WHO) should jointly sponsor an international conference to review the consequences of the accident and to seek a common and conclusive understanding of their nature and magnitude. The International Conference on One Decade after Chernobyl: Summing up the Consequences of the Accident was held at the Austria Center, Vienna, on 8-12 April 1996. Refs, figs, tabs

  18. Chernobyl today. Impressions and informations from a visit to the nuclear power plant in July 1995

    A visit to Chernobyl by Western experts was organized within the 1995 Nuclear Technology Conference. The region, which had been evacuated after the reactor accident in the Chernobyl-4 nuclear generating unit on April 26, 1986, now again offers employment to some 15,000 people. 120 scientific organizations are conducting studies in the protected zone. No indications of any consequences of the accident can be seen in the natural environment. As the manager of the power plant put it: 'This is a good region to live in.' In order to maintain this standard of living, the agencies responsible in Ukraine plan to repair unit 2, which has been down because of a fire in the turbine building since 1991, resynchronize it with the power grid, and run it up until 2002. Unit 1 is to be decommissioned in 1998; unit 3, in 2001. The biggest problem on site is the stability of the sarcophagus around unit 4. (orig./UA)

  19. Chernobyl: A first-hand account

    The author, living in Moscow at the time, was traveling by night train to visit family in Kiev at the time of the chernobyl accident. He recalls a passenger in his compartment asking if anyone had noticed in the morning press about the explosion in Chernobyl. In Kiev, about 50 mi from Chernobyl by air, he noted on arrival that everyone was calm - the city quiet with no rumors or gossip. He contrasts this with the world being alert, in despair, full of alarm. On failure to reach old friends by phone, he thought they had left the city for at least 4-day vacations - May 1 and 2 holidays plus Saturday and Sunday. He continues to recount the life as usual situation aided and abetted by the governments lack of information and misinformation on the perilously dangerous radioactivity and extent of the disaster. He notes friends showing him a January 1986 copy of Izvestia with an article about the Chernobyl unit, several months before, being named winner in a competition among all nuclear power stations in the USSR

  6. Radionuclide migration in the Chernobyl contamination zone

    It is well known that fallout of 137Cs reaching the land soils with precipitation was rapidly and tightly sorbed to the fine fraction of sediment or soils. The majority of the 137Cs is retained in the top few centimetres of the soil or sediment profiles (Loughran et al, 1993, Owens et al, 1996). In the absence of strong variations in precipitation over a relatively small area the total bomb-derived 137Cs fallout can assumed to be spatial uniform. The Chernobyl 137Cs fallout was mostly connected with one or two rains. So the spatial variability of this 137Cs can be higher. Furthermore because the explosion on the Chernobyl nuclear plant happen together with fire, a lot of ashes particles with radionuclide were distributed within vast areas. So even microvariability of Chernobyl 137Cs can be very high in some places. The horizontal migration of 137Cs connects with soil erosion processes that dominate on the agricultural lands of the Central Russia. The main goal of this investigation is to evaluate the caesium-137 horizontal and vertical migration within typical landscape of the Central Russia 11 years after the Chernobyl accident

    2013-01-01

    First, this article argues that trade mark law should be approached in a supplementary way, called reconfiguration. Second, the article investigates such a reconfiguration of trade mark law by exploring the interplay of trade marks and service transactions in the Single Market, in the cross......-border setting, with a particular focus on small business and consumers. The article's overall message is to call for a rethink of received wisdom suggesting that trade marks are effective trade-enabling devices. The case is made for reassessing how we think about European trade mark law....

  10. Thyroid cancer in Belarus after Chernobyl: International thyroid project. International Programme on the Health Effects of the Chernobyl Accident

    The Chernobyl accident has demonstrated what was always known but perhaps has not been as fully acknowledged as it might, namely that national or other geographical boundaries are no defence against radioactive fallout. Much (some 2.2 millions) of the approximately 10 million population of Belarus have been, and are still being, exposed to the radiation resulting from the accident. The most obvious adverse effect of the radiation is on the condition of the thyroid system in children. Now, only just over eight years after the accident, we are experiencing an increase in childhood thyroid cancer which is particularly marked in those closest to the site of the accident. In young children thyroid cancer is an extremely rare condition and thus although at present the numbers of cases (more than 250 since the accident) is not large in absolute terms it is a sufficiently important development to capture the interest of the international medical and scientific community and to give rise to considerable apprehension as to the future development of the outbreak. Although this increase in thyroid cancer has not been definitively attributed to the Chernobyl accident, and indeed a major aim of this project is to elucidate the cause of the cancer, the fact of the exposure of the population of Belarus to the isotopes of iodine at the time of accident, and what we have learned from the experience in the Marshall Islands following the testing of the first hydrogen bomb on Bikini Atoll lead us to consider the accident as the most likely cause of the increase. Belarus is a relatively small and newly independent country. By any standards the Chernobyl accident was a technological disaster of enormous proportions causing damage to the environment over vast land areas. Necessarily it must be a major concern for us and an issue to be considered in the planning of our future. Its impact on the future health of our nation must be assessed as objectively and dispassionately as possible and

  12. Franco-German cooperation on Chernobyl

    This document presents the franco-german cooperation on Chernobyl. The purpose of this cooperation is to collect and validate all the data available in order to build a reliable and unbiased data-base. This cooperation is based on 3 axis and is funded with 6 million Ecus for 3 years. The 3 programmes are: i) the safety of the sarcophagus, ii) the radio-ecological consequences of the accident, and iii) the impact on health. The Chernobyl accident has had dramatic effects on the environment which were till now more or less under-estimated, the program on radio-ecological consequences will include information about the storage places of the wastes coming from the massive soil decontamination as well as information about the contamination of the artificial lake that was used to drain the low part of the reactor building and about the contamination of underground waters.

  13. Initiative for decommissioning of Chernobyl Nuclear Plant

    Construction of the New Safety Confinement (NSC) for the Chernobyl unit 4 started 2010, after about 25 years of Chernobyl accident and will complete summer of 2015. This project is being conducted by assistance of EU, USA and other countries including Japan. NSC can cover the whole facility of unit 4, and is installed various components or tools including big bridge crane for decommissioning unit 4 and has durability over 100 years. In addition to construction of NSC, various activities for preparing the decommissioning including developing the technology of monitoring the inside of destructive building and remote access technologies. The spent fuel storage facility and waste proposal facilities are also constructed.. These activities include many valuable information about how to smoothly conduct the decommissioning and it would be important to learn the above activities in conducting the post-processing activities on the Fukushima-Daiichi accident successfully.

  14. Chernobyl: the effects on public 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.)

  15. New predictions for Chernobyl childhood thyroid cancers

    New, firmer predictions are presented for the number of childhood thyroid cancers caused by Chernobyl: between 3300 and 7600 over all time, with a central estimate of 4400. The high efficacy of medical treatment suggests that at least 70% of the sufferers should survive the illness, with 95% or better survival a realistic target given early and skilled surgery and treatment. In view of the reported lack of evidence for other long-term health effects and the comparatively small number of early deaths, the total figure for deaths attributable to the Chernobyl accident may currently be estimated as from a few hundreds to a few thousands, with one thousand as a reasonable central estimate.

    Information system 'Chernobyl' of EMERCOM of Russia included the following: Central bank of generalized data, Bank of models, Information system for federal and local authorities. The analysis of many phenomena demanded retrospective data collection. In that way, banks of primary data were created and experience of analysis of directly accident information was acquired. The main element of the system-analytic support is the administrative information system of the Department for elimination of consequences of radiological and other disaster of EMERCOM of the Russian Federation. Administrative information system is intended for providing specialized program-technical complexes and systematized data related to the Chernobyl accident effects and measures on their elimination for heads and specialists of Central staff and territorial and regional administrative bodies, all other interested ministries, departments and organization

  19. Western reactors: how they compare with Chernobyl

    The author explains why western light water reactors are intrinsically more dangerous than the RBMK, Chernobyl design. It is also argued that for the fast breeder reactors (such as the PFR at Dounreay and the Super Phenix at Creys Melville) are more dangerous and could actually explode like an atomic bomb. This is contrary to official assurances that the Western reactors are of a safer design and more safely operated than the Chernobyl reactor, and so a similar accident could not happen here. The PWRs and BWRs are compared with the RBMK as to pressure vessels/no pressure vessel, fuel rods, reactor containment and containment building. The superiority of Western engineering and reactor operation is also disputed, with the Three Mile Island accident used as evidence. (U.K.)

  20. Chernobyl experience of emergency data management

  7. Chernobyl -- the fallout and the farmer

    Following the Chernobyl accident an increase in the levels of airborne radioactivity was first detected in Ireland during the period 2nd-4th May, 1986. Heavy rainfall resulted in significant ground deposition of this activity, and the environmental monitoring programme set up by the Nuclear Energy Board ( now the Radiological Protection Institute of Ireland) has determined the distribution and level of radionuclides in the major food items consumed by the Irish population

  8. Preliminary dose assessment of the Chernobyl accident

    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 131I was the predominant fission product. The time of arrival of the plume and the maximum concentrations of 131I 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 106 person-rem. From the Soviet report, it appears that a first year population dose of about 2 x 107 person-rem (2 x 105 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

  10. Trauma management: Chernobyl in Belarus and Ukraine.

    Zhukova, Ekatherina

    2016-06-01

    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. PMID:27191056

  11. Consequences of the Chernobyl accident in Lithuania

    After the Chernobyl accident of 26 April, 1986, population dose assessment favours the view that the radiation risk of population effected by the early fallout would be different from that in regions contaminated later. Taking into account the short half-time of the most important radioactive iodine isotopes, thyroid disorders would be expected mainly to follow the early fallout distribution. At the time of accident at Unite 4 of the Chernobyl NPP, surface winds were from the Southeast. The initial explosions and heat carried volatile radioactive materials to the 1,5 km height, from where they were transported over the Western part of Belarus, Southern and Western part of Lithuania toward Scandinavian countries. Thus the volatile radioiodine and some other radionuclides were detected in Lithuania on the very first days after the accident. The main task of the work - to conduct short Half-time radioiodine and long half-time radiocesium dose assessment of Lithuanian inhabitants a result of the early Chernobyl accident fallout

  12. Health consequences [of the Chernobyl accident

    The World Health Organisation Conference on the Health Consequences of the Chernobyl and Other Radiological Accidents, held in Geneva last November, is reported. The lack of representation from the civil nuclear industry led often to one-sided debates instigated by the anti-nuclear lobbies present. Thyroid cancer in children as a result of the Chernobyl accident received particular attention. In Belarus, 400 cases have been noted, 220 in Ukraine and 60 in the Russian Federation. All have been treated with a high degree of success. The incidence of this cancer would be expected to follow the fallout path as the main exposure route was ingestion of contaminated foods and milk products. It was noted that the only way to confirm causality was if those children born since the accident failed to show the same increased incidence. Explanations were offered for the particular susceptibility of children to thyroid cancer following exposure to radiation. Another significant cause of concern was the health consequences to clean-up workers in radiological accidents. The main factor is psychological problems from the stress of knowing that they have received high radiation doses. A dramatic increase in psychological disorders has occurred in the Ukraine over the past ten years and this is attributed to stress generated by the Chernobyl accident, compounded by the inadequacy of the public advice offered at the time and the socio-economic uncertainties accompanying the breakup of the former USSR.

  13. The Cuban Chernobyl program. realities and perspectives

    Full text: In April of 1990 started the 'Cuban Chernobyl Program'. This program was designed to offers specialised medical attention and to develop a rehabilitation plan with children from areas affected by the Chernobyl accident. Up to the moment more than 21 500 children and adults had been assisted in the program, with a significant set of medical procedures done. Dosimetric, biomedical and psychological research had been also carried out as part of the program. The more significant medical attention activities include the treatment of 289 children with haematological disorders, including 6 bone marrow transplantation, more than 100 important surgical interventions, and the treatment of 117 children with solid tumors. The dosimetric results on more than 7000 children are including in a database with information on internal Cs 137 contamination, internal, external and total doses, children living location, and its contamination by Cs 137, and other significant information for radiological impact evaluation. The behaviour of all the medical information of the program in relation to the contamination of the land and the internal contamination of the children was analysed using this database. The program has accumulated an experience of interest for physicians, psychologists and in general persons interested in Chernobyl consequences

It is now well documented that children and adolescents exposed to radioiodines from Chernobyl fallout have a sizeable dose-related increase in thyroid cancer, with the risk greatest in those youngest at exposure and with a suggestion that deficiency in stable iodine may increase the risk. Data on thyroid cancer risks to other age groups are somewhat less definitive. In addition, there have been reported increases in incidence and mortality from non-thyroid cancers and non-cancer end points. Although some studies are difficult to interpret because of methodological limitations, recent investigations of Chernobyl clean-up workers ('liquidators') have provided evidence of increased risks of leukaemia and other haematological malignancies and of cataracts, and suggestions of an increase in the risk of cardiovascular diseases, following low doses and low dose rates of radiation. Further careful follow-up of these populations, including the establishment and long-term support of life-span study cohorts, could provide additional important information for the quantification of radiation risks and the protection of persons exposed to low doses of radiation.

    The accident at the Chernobyl NPP in 1986 was the most severe in the history of the nuclear industry, causing a huge release of radionuclides over large areas of Europe. The recently completed Chernobyl Forum concluded that after a number of years, along with reduction of radiation levels and accumulation of humanitarian consequences, 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 to be addressed by the authorities. The majority of the affected land is now safe for life and economic activities. However, in the Chernobyl Exclusion Zone and in some limited areas of Belarus, Russia and Ukraine some restrictions on land-use should be retained for decades to come. Most of the 600,000 emergency and recovery operation workers and five million residents of the contaminated areas in Belarus, Russia and Ukraine received relatively minor radiation doses which are comparable with the natural background levels. Apart from the dramatic increase in thyroid cancer incidence among those exposed at a young age and some increase of leukaemia and solid cancer in most exposed workers, there is no clearly demonstrated increase in the somatic diseases due to radiation.

  16. Chernobyl: the plant that refuses to die

    Despite the cracking of the Sarcophagus enclosing Reactor 4 and recent observations of increased radiation inside, no decision on the future of the Chernobyl plant has been made. There is pressure from the G7 countries to close it down, but reluctance in Ukraine for a variety of reasons. Closure of the remaining functioning reactors at the plant would require new capacity to be substituted in order to meet the Ukraine's power demand and support its already ailing economy. Controversially, the Ukraine would like the new capacity to come from the completion of two VVER plants at Rovno and Khmelnitsky but it would embarrass the European Bank for Reconstruction and Development to be seen to be financing the replacement of Chernobyl by more nuclear reactors. Opposition to plant closure also comes from those concerned for the future of the town of Slavutich which houses the Chernobyl workforce of 6,000 and their families. The fear is that closure would mean a sudden slide into poverty for the 24,000 inhabitants. Moreover, should the workforce disappear, who would look after the Sarcophagus? It is the future of the Sarcophagus which should be the priority of all parties to the debate. Opinions differ on the consequences of the collapse of the present structure but they could constitute another disaster. (UK)

  18. The legal issues of Chernobyl

    According to international law the Federal Republic of Germany has a right to claim compensations from the Soviet Union. This all the more as both states have signed the treaty of Nov. 13, 1979 which as part of the UN Economic Commission for Europe (ECE) is known as the ''Convention on Long-Range Transboundary Air Pollution''. By civil law victims may sue a Kiev court for compensations or else sue for damages in the Federal Republic of Germany. It is very unlikely that the reactor management itself will pay any damages. According to the Atomic Energy Law, paragraph 38, 2 and paragraph 34, 1 p. 2 victims in the Federal Republic of Germany may claim compensations up to a maximum of 1 billion marks from the Federal Government. However, compensations may only be sued for if attempts to sue a Soviet court have failed. Compensations must be claimed at the Federal Administrative Board in Cologne. (HP)

  19. Surveillance of congenital malformations in Belarus. Chernobyl aftermath

    Full text: In order to study possible genetic effects of the Chernobyl accident in human population a comparative analysis of the prevalence at birth of congenital malformations (CM) was performed on region and area administrative levels basing on the data of Belarus registry of CM permanently functioning since 1979. An attempt was made to evaluate dose dependence of the effects under study. We analyzed time trends of the prevalence at birth of 9 so called 'mandatory registered' nosologic units of CM. These group of CM could be easily diagnosed within the neonatal period and were assigned for registration at creation of the registry. Over 12 thousand cases registered within the period of 1981 to 2004 in 4 regions as well as about 3 thousand cases found in 47 rayons highly contrasting by radiation exposure were scrutinized. No long-term impact of the Chernobyl release on prevalence rates of surveyed CM was shown. Since the middle 80-s a similar steady increasing trend was observed as in contaminated, as in control areas with a tendency to stabilization after middle 90-s. We fail to reveal a dose dependence for CM prevalence rates calculated for the whole post-accidental period. Nonetheless, during the first years after the accident situation in contaminated areas was notably different from those in the control. Within the period of 1987 to 1989 a significant access of CM prevalence was registered in the strict radiological control area (Cs 137 soil contamination over 555 kBq/m2) as compared to non-contaminated zone. Relative risk was estimated as RR1987-1989 = 1.57 with 95% confidence interval being 95%CI = [1.29; 1.89]. Before the accident no difference in prevalence rates was marked (RR1981-1986 = 0.93; 95%CI = [0.80; 1.09]); nor it was evident in the farther post-accidental period (RR1990-2004 = 0.99; 95%CI = [0.80; 1.09]). Anomalies with high contribution of dominant de novo mutations (polydactyly, reduction defects of limbs and multiple CM) played principal

    It is well recognized that the use of external irradiation of the head and neck to treat patients with various non-thyroid disorders increases their risk of developing papillary thyroid carcinoma years after radiation exposure. An increased risk of thyroid cancer has also been reported in survivors of the atomic bombs in Japan, as well as in Marshall Island residents exposed to radiation during the testing of hydrogen bombs. More recently, exposure to radioactive fallout as a result of the Chernobyl nuclear reactor accident has clearly caused an enormous increase in the incidence of childhood thyroid carcinoma in Belarus, Ukraine, and, to a lesser extent, in the Russian Federation, starting in 1990. When clinical and epidemiological features of thyroid carcinomas diagnosed in Belarus after the Chernobyl accident are compared with those of naturally occurring thyroid carcinomas in patients of the same age group in Italy and France, it becomes apparent that the post-Chernobyl thyroid carcinomas were much less influenced by gender, virtually always papillary (solid and follicular variants), more aggressive at presentation and more frequently associated with thyroid autoimmunity. Gene mutations involving the RET proto-oncogene, and less frequently TRK, have been shown to be causative events specific for papillary cancer. RET activation was found in nearly 70% of the patients who developed papillary thyroid carcinomas following the Chernobyl accident. In addition to thyroid cancer, radiation-induced thyroid diseases include benign thyroid nodules, hypothyroidism and autoimmune thyroiditis, with or without thyroid insufficiency, as observed in populations after environmental exposure to radioisotopes of iodine and in the survivors of atomic bomb explosions. On this basis, the authors evaluated thyroid autoimmune phenomena in normal children exposed to radiation after the Chernobyl accident. The results demonstrated an increased prevalence of circulating thyroid

    Full Text Available Bite mark analysis plays an important role in personal identi- fi cation in forensic odontology. They are commonly seen in violent crimes such as sexual assaults, homicides, child abuse, etc. Human bites are common on the face and are usually seen on prominent locations of the face such as the ears, nose and lips. Individual characteristics recorded in the bite marks such as fractures, rotations, attrition, and congenital malformations are helpful in identifying the individual who caused it. We are reporting the case of a 55-year-old lady with bite marks on her left ear, who was allegedly assaulted by the suspect. On the basis of characteristic features of the suspect’s dentition, it was concluded that the bite marks seen on the victim was most probably caused by the suspect.

  4. Drosophila as a model object in to study Chernobyl NPP after

    Complete text of publication follows. Water extractions of soil probes, which were selected on areas with different density of radioactive pollutions near Chernobyl exclusion zone ('Apple-tree garden' (Chernobyl); 'Island' (the bank of the pond-cooler of the Chernobyl nuclear power plant); 'Torch' (the area of revegetation near the Chernobyl nuclear power plant); 'Red forest' (side of a road) and 'Red forest' (edge of a forest)) were investigated. Dosimetric metering of all studied areas was conducted. γ- and β-activities of soil probes were determined by spectrometry and radiochemistry methods. The contents of trace elements in the soil probes of areas the 'Appletree garden' and 'Island' were determined. Water extractions from soil were prepared according to standard method (ratio - 1 : 2,5). The mutagenicity of water extractions of soil was estimated using the test of frequency of the sex-linked lethal mutations of Drosophila melanogaster. Water extractions were directly adds to a nourishing medium instead of standard component - distilled water. The strain of wild type of Drosophila Canton-S and natural populations of Drosophila from Pyriatin and Chernobyl were used in our study. The natural populations of Chernobyl and Pyriatin were included in study for more fully estimation of influence of factor on genetic processes of Drosophila, because of presence of unspecific adaptations of natural populations from radioactive polluted territories (as was shown before). According to dosimetric analysis data radiation activity of all water extractions of soils did not exceed a natural background. The probes of soil from areas the 'Red forest' and the 'Torch' were marked the higher activity; total activity of them was over 110 Mbk/kg. It is possibly that this fact was the reason of the absence of descendants in all variants of experiments conducted on medium with water extraction the 'Red forest' and in a variant of experiments concerned on study of activity of water

    The Paris appeal court has dismissed the charges against P. Pellerin who was the head of the SCIRP (service of protection against the ionizing radiations) at the time of the Chernobyl accident. The appeal court confirms that P.Pellerin never said that the Chernobyl plume stopped at the French border but instead he said that the Chernobyl plume entered the French territory but the radioactivity level was so low that it was unnecessary to take sanitary steps. P.Pellerin based his decision on the results of 6500 controls performed by the SCIRP in May and June 1986. Seven other European countries recommended not to take sanitary measures. The increase of thyroid cancers that has happened in all industrialized countries and that affect only adults, can not due to Chernobyl contamination because child's thyroid is far more sensitive than adult's. The increase of thyroid cancer is mainly due to a better detection of the tumors. (A.C.)

  7. Consequences of Chernobyl accident in Europe

    Full text: Among nuclides emitted from the destroyed Chernobyl reactor only radioiodine and radiocesium were of serious health concern. The amount of iodine-131 released in this catastrophe was about 180 times lower than during the total release of this nuclide from 77 nuclear weapon tests performed in remote areas in the record year of 1962, and the release of cesium-137 was only five times lower. However, the bulk of Chernobyl emission was confined in time to only twelve days, and its geographical dispersion was much smaller and closer to populated areas than that of nuclear tests debris. Only a small part of cesium-137 and cesium-134 from the Chernobyl reactor reached the Southern Hemisphere, via stratospheric transport routes. Therefore, radiation doses received by the population from the Chernobyl radionuclides was in the affected areas higher than from the nuclear tests fallout. In part of Europe the doses received by children in the thyroid gland from iodine-131 radiation were high enough to expect an increase in thyroid cancers. In the contaminated regions of Belarus, Ukraine and Russia the estimated thyroid doses in children could reach up to several thousand mSv. In a group of >100,000 persons evacuated during the first few weeks, the average thyroid dose in children under 3 years of age was about 1000 mSv, and in adults about 70 mSv. Between 1986 and 1995 about 700 thyroid cancers in children were reported from Belarus, Ukraine and Russia, most of which may be attributed to Chernobyl radiation. About 95% of these cancers are believed to be curable. The whole body dose from cloud passage, ground deposition and intake of cesium-137 and of other radionuclides was much smaller than thyroid doses, and do not pose a real risk to the population. The average lifetime (70 years) whole body doses in the most contaminated regions of Belarus ranged between 88 and 160 mSv, in Ukraine 84 and 120 mSv and in Russia 78 to 130 mSv. The average doses to 800

  9. International nuclear law in the 25 years between Chernobyl and Fukushima and beyond

    This paper is dedicated both to legal developments since the accident at the Chernobyl nuclear power plant 25 years ago and possible legal implications of the accidents at Fukushima Daiichi which occurred after Japan was struck by a devastating earthquake on 11 March 2011. Following the accident at Three Mile Island in 1979 and at Chernobyl in 1986, Fukushima will be remembered as the third major accident in the history of civilian nuclear power reactors. Yet Chernobyl was and remains the worst trauma in this history as a result of which nuclear developments slowed down significantly. Eventually, the industry emerged as a safer and stronger technology, particularly because the 25 years between Chernobyl and Fukushima were marked by an exceptional national and international commitment to nuclear safety and emergency preparedness so as to prevent accidents and minimise potential damages, if such occur. From a legal point of view it is safe to say that the nuclear industry is one of the most strictly regulated. However, it is equally safe to say that there is no zero risk technology and that accidents can happen. For several weeks after the tragic events in Japan the world's focus turned - justifiably so - to the Fukushima Daiichi nuclear power units. It was nevertheless astonishing to observe that the real tragedy, the terrible loss of lives, swept away villages, and the chaos following the breakdown of all kinds of infrastructure were treated as a sideshow compared with the dramatic images of explosions at the Fukushima Daiichi units and helicopters trying to drop seawater into the spent fuel pools. The live broadcasting of accidents might present one of the first lessons to be learnt in our Internet and 24-hour news channel era which did not exist at the time of Chernobyl. The international legal community will also face challenges as the accident has put 25 years of international co-operation and international nuclear law-making to its first serious test. The

  10. Environmental consequences of the Chernobyl accident and their remediation: Twenty years of experience. Report of the UN Chernobyl Forum Expert Group 'Environment' (EGE). Working material

    The purpose of this report is to provide an up-to-date evaluation of the environmental effects of the 26 April 1986 accident at the Chernobyl Nuclear Power Plant. Even though it is now nearly 20 years after the accident and substantial monies have been spent on such evaluations, there are still many conflicting reports and rumours. This joint report has been developed with the full cooperation of the United Nations (UN) family of relevant organisations and with political representatives from the three more affected countries: Ukraine, Belarus, and the Russian Federation. In addition, recognised scientific experts from the three countries and additional international experts provided the basis for the preparation of reports for review by the actual members of the Chernobyl Forum. The - Chernobyl Forum - is a high-level political forum whose suggestion for existence was initiated by the International Atomic Energy Agency (IAEA) in cooperation with the Food and Agriculture Organisation (FAO), the United Nations Office for Coordination of Humanitarian Affairs (OCHA), the United Nations Development Programme (UNDP), the United Nations Environment Programme (UNEP), the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR), the World Health Organisation (WHO), and the World Bank, as well as the competent authorities of Belarus, the Russian Federation, and Ukraine. The organisational meeting of the Chernobyl Forum was held on 3-5 February 2003, at which time the decision was reached to establish the Forum as an ongoing entity of the above named organisations. Thus, the organisational meeting of the Forum decided to establish the Chernobyl Forum as a series of managerial, expert and public meetings in order to generate authoritative consensual statements on the health effects attributable to radiation exposure arising from the accident and the environmental consequences induced by the released radioactive materials, to provide advice on
