This book was released on 2023-08-09 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radionuclides of both natural and human made origin exist throughout the environment. These radionuclides can be transferred to plants and animals that are consumed by humans, thereby resulting in exposure to ionizing radiation and an internal radiation dose. This Safety Report provides information on the observed distributions of concentrations of natural radionuclides in various food products, on the use of ‘total diet’ and other studies to assess ingestion doses, and on radionuclide concentrations in natural mineral waters. Different dose assessment methodologies are presented and the advantages and disadvantages of each is discussed, along with approaches used for managing non-radioactive contaminants in food. This publication is jointly sponsored by the IAEA, the Food and Agriculture Organization of the United Nations and the World Health Organization. It is intended to support Member States in the assessment and management of radionuclides in food, and the alignment of national policies with Requirement 51 of IAEA Safety Standards Series No. GSR Part 3, related to radionuclides in food and drinking water.

This book was released on 1995-05-16 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing public concern about releases of radiation into the environment has focused attention on the measurement of exposure of people living near nuclear weapons production facilities or in areas affected by accidental releases of radiation. Radiation-Dose Reconstruction for Epidemiologic Uses responds to the need for criteria for dose reconstruction studies, particularly if the doses are to be useful in epidemiology. This book provides specific and practical recommendations for whether, when, and how studies should be conducted, with an emphasis on public participation. Based on the expertise of scientists involved in dozens of dose reconstruction projects, this volume: Provides an overview of the basic requirements and technical aspects of dose reconstruction. Presents lessons to be learned from dose reconstructions after Chernobyl, Three Mile Island, and elsewhere. Explores the potential benefits and limitations of biological markers. Discusses how to establish the "source term"â€"that is, to determine what was released. Explores methods for identifying the environmental pathways by which radiation reaches the body. Offers details on three major categories of dose assessment.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides extensive and comprehensive information to researchers and academicians who are interested in radionuclide contamination, its sources and environmental impact. It is also useful for graduate and undergraduate students specializing in radioactive-waste disposal and its impact on natural as well as manmade environments. A number of sites are affected by large legacies of waste from the mining and processing of radioactive minerals. Over recent decades, several hundred radioactive isotopes (radioisotopes) of natural elements have been produced artificially, including 90Sr, 137Cs and 131I. Several other anthropogenic radioactive elements have also been produced in large quantities, for example technetium, neptunium, plutonium and americium, although plutonium does occur naturally in trace amounts in uranium ores. The deposition of radionuclides on vegetation and soil, as well as the uptake from polluted aquifers (root uptake or irrigation) are the initial point for their transfer into the terrestrial environment and into food chains. There are two principal deposition processes for the removal of pollutants from the atmosphere: dry deposition is the direct transfer through absorption of gases and particles by natural surfaces, such as vegetation, whereas showery or wet deposition is the transport of a substance from the atmosphere to the ground by snow, hail or rain. Once deposited on any vegetation, radionuclides are removed from plants by the airstre am and rain, either through percolation or by cuticular scratch. The increase in biomass during plant growth does not cause a loss of activity, but it does lead to a decrease in activity concentration due to effective dilution. There is also systemic transport (translocation) of radionuclides within the plant subsequent to foliar uptake, leading the transfer of chemical components to other parts of the plant that have not been contaminated directly.

Available in PDF, EPUB and Kindle. Book excerpt: Radioactivity in the Environment, Second Edition, presents the facts on the presence of both natural and manmade radionuclides in the environment. Sources of ionizing radiation that can lead to human exposure are discussed, including natural sources, nuclear explosions, nuclear power generation, the use of radiation in medical, industrial and research purposes, and radiation-emitting consumer products. In this thoroughly updated edition, users will find new sections on developments in radioactive nuclides in nature and technologically modified exposure to natural radiation, new threats by terrorist individuals, groups and countries, changes to the status of nuclear power in the world, and more. Additional new sections cover radioisotopes in geo-prospecting and the oil industry, the use of radiation in environmental protection, detector types and detectors used for personal dosimetry, the "Dirty Bomb", the Fukushima accident, and North Korea testing sites and nuclear capabilities. Includes details of analytical laboratory procedures for radioactivity measurement in different samples Features a new chapter on decontamination after radiation exposure Expands the discussion on nuclear fusion to cover ITER and other installations

Available in PDF, EPUB and Kindle. Book excerpt: The Symposium on Radionuclides in the Food Chain, sponsored by the Interna tional Life Sciences Institute in association with the International Institute for Applied Systems Analysis, was intended to bring together policymakers and other representatives of the food industry with radiation experts involved in measuring and assessing radioactivity in foodstuffs. The symposium was made timely by the problems arising from the nuclear reactor accident at Chernobyl, in the USSR, which brought out the lack of international agreement on guidance for responding to such radionuclide contamination of food and foodstuffs. The presentations by the radiation experts covered the sources of radionu clides-natural radioactivity, fallout from nuclear weapons tests, routine releases from nuclear facilities, and various nuclear accidents. The speakers represented a broad distribution in both scientific disciplines and international geographic origin. They summarized the available data on measurements and indicated the current procedures for assessing radiation exposure. It was hoped that the food industry representatives would bring out the problems posed to industry and governments by the presence of radioactivity in food.
