This book was released on 2019-09-24 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication describes and summarizes the work of the MODARIA (modelling and data for radiological impact assessments) Programme Working Group 10. MODARIA was set up to continue the IAEA's activities in the field of testing, comparing and developing guidance on the application of models to assess radiation exposures to humans and radiological impacts on the environment. Different aspects of the MODARIA programme were addressed by ten working groups. The current publication presents the work undertaken by Working Group 10 on the modelling of marine dispersion and transfer of radionuclides accidentally released from land-based facilities. Two marine dispersion scenarios were studied. These scenarios simulated dispersion of radionuclides in the Baltic Sea following the Chernobyl accident, and dispersion in the Pacific Ocean following the Fukushima Daiichi nuclear power plant accident. The publication details some general conclusions and presents a comparison of model performance when applied to the above scenarios. The difficulties of developing operative modelling systems for supporting decision making in cases of emergencies in highly dynamic environments are highlighted.

Download or read book Modelling the Dispersion of Radionuclides in the Marine Environment written by Raúl Periánez and published by Springer Science & Business Media. This book was released on 2005-03-07 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a practical guide to the subject of numerical modelling of radioactivity dispersion in the marine environment. Thus, the techniques and numerical procedures required are explained in detail, with the aim of enabling the reader to build a real mathematical model. The book covers basic concepts and techniques, such as solving the advection-diffusion equation in a simple 1D form, as well as the most recent developments (full 3D models for non-conservative radionuclides including chemical reactions and speciation). A chapter is dedicated to the basic hydrodynamic modelling that is always required to simulate the dispersion of tracers in the sea; Eulerian and Lagrangian modelling techniques are also described. A chapter describes sensitivity and uncertainty analysis, the final stage in modelling works. A review on some published radionuclide dispersion models is also included. The book also includes a CD-ROM with a Lagrangian dispersion model of the Strait of Gibraltar and several Fortran codes developed by the author which can be used to reproduce some of the cases described in the book.

Book Synopsis Soil-Plant Transfer of Radionuclides in Non-Temperate Environments by : International Atomic Energy Agency
Download or read book Soil-Plant Transfer of Radionuclides in Non-Temperate Environments written by International Atomic Energy Agency and published by . This book was released on 2021-11-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication considers radionuclide transfer in tropical and arid environments with a focus on root uptake by crops from soils. The data collected and analysed are relevant for estimating the transfer of radionuclides through food chains to humans and for assessing radiation doses to the public due to intakes of these radionuclides in plant products used as food. The data relate to equilibrium conditions between the radionuclide's dynamics into and out of the compartments of the environment and are appropriate for radiological environmental impact assessment in planned and existing exposure situations where such conditions have been established. Moreover, this publication classifies the data according to an international climate classification scheme and compares the summary values derived for tropical and arid environments with those presented in IAEA Technical Reports Series No. 472 for temperate environments.

Download or read book Inventory of Radioactive Material Resulting from Historical Dumping, Accidents and Losses at Sea written by International Atomic Energy Agency and published by IAEA Tecdoc. This book was released on 2016-02-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1989 the Contracting Parties to the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (the London Convention 1972) requested that the IAEA undertake the preparation of a global inventory of radioactive materials entering the marine environment from all origins. The IAEA subsequently established a global inventory which included information officially reported in or obtained from open literature and confirmed by the countries involved, on (i) the dumping at sea of radioactive waste; and (ii) marine accidents and losses involving radioactive materials. The inventory is intended as a centralized information base against which the impact of specific sources of radioactive material entering the marine environment can be assessed and compared. In 2006 the IAEA received the request to update those inventories. The present publication includes additional information provided recently by some IAEA Member States and contracting parties to the London Convention 1972 and Protocol 1996 within a process of updating the inventory which concluded in 2014, together with the information contained in previous IAEA publications. A CD ROM provides tables, maps and a database with detailed information.
Book Synopsis Behavior of Radionuclides in the Environment III by : Kenji Nanba
Download or read book Behavior of Radionuclides in the Environment III written by Kenji Nanba and published by Springer Nature. This book was released on 2022-03-14 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, the third in the series Behavior of Radionuclides in the Environment, is dedicated to Fukushima. Major findings from research since 2011 are reviewed concerning the behavior of radionuclides released into the environment due to the Fukushima Dai-ichi Nuclear Power Plant accident, including atmospheric transport and fallout of radionuclides, their fate, and transport in the soil-water environment, behavior in freshwater, coastal and marine environment, transfer in the terrestrial and agricultural environment. Volume III discusses not only radionuclides dynamics in the environment in the short- and mid-term, but also modeling and prediction of long-term time changes. Along with reviews, the book contains original data and results not published previously. It was spearheaded by the authors from the Institute of Environmental Radioactivity at Fukushima University, established two years after the Fukushima accident, with their collaborators from Japan, Russia, and Ukraine. The knowledge emerging from the studies of the environmental behavior of Fukushima-derived radionuclides enables us to move forward in understanding mechanisms of environmental contamination and leads to better modeling and prediction of long-term pollution effects in general.

Download or read book Sources, Effects and Risks of Ionizing Radiation, United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) 2016 Report written by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) and published by United Nations. This book was released on 2017-04-25 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.
Book Synopsis Oil in the Sea III by : National Research Council
Download or read book Oil in the Sea III written by National Research Council and published by National Academies Press. This book was released on 2003-03-14 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.

Book Synopsis Managing Ocean Environments in a Changing Climate by : Kevin J. Noone
Download or read book Managing Ocean Environments in a Changing Climate written by Kevin J. Noone and published by Newnes. This book was released on 2013-06-29 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Managing Ocean Environments in a Changing Climate summarizes the current state of several threats to the global oceans. What distinguishes this book most from previous works is that this book begins with a holistic, global-scale focus for the first several chapters and then provides an example of how this approach can be applied on a regional scale, for the Pacific region. Previous works usually have compiled local studies, which are essentially impossible to properly integrate to the global scale. The editors have engaged leading scientists in a number of areas, such as fisheries and marine ecosystems, ocean chemistry, marine biogeochemical cycling, oceans and climate change, and economics, to examine the threats to the oceans both individually and collectively, provide gross estimates of the economic and societal impacts of these threats, and deliver high-level recommendations. Nominated for a Katerva Award in 2012 in the Economy category State of the science reviews by known marine experts provide a concise, readable presentation written at a level for managers and students Links environmental and economic aspects of ocean threats and provides an economic analysis of action versus inaction Provides recommendations for stakeholders to help stimulate the development of policies that would help move toward sustainable use of marine resources and services

Book Synopsis Environmental Consequences of the Chernobyl Accident and Their Remediation by : International Atomic Energy Agency
Download or read book Environmental Consequences of the Chernobyl Accident and Their Remediation written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.

Download or read book Environmental Contamination from the Fukushima Nuclear Disaster written by Teruyuki Nakajima and published by Cambridge University Press. This book was released on 2019-08-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2011 disaster at the Fukushima Daiichi Nuclear Power Station led to serious radioactive contamination of the environment. Due to transportation by seasonal wind and ocean currents, these radioactive materials have now been observed in many places in the Northern Hemisphere. This book provides a unique summary of the environmental impact of the unprecedented accident. It covers how radioactive materials were transported through the atmosphere, oceans and land. The techniques used to investigate the deposition and migration processes are also discussed including atmospheric observation, soil mapping, forest and ecosystem investigations, and numerical simulations. With chapters written by international experts, this is a crucial resource for researchers working on the dispersion and impact of radionuclides in the environment. It also provides essential knowledge for nuclear engineers, social scientists and policymakers to help develop suitable mitigation measures to prepare for similar large-scale natural hazards in the future.
