Numerous sources of ionizing radiation can lead to human exposure: natural sources, nuclear explosions, nuclear power generation, use of radiation in medical, industrial and research purposes, and radiation emitting consumer products. Before assessing the radiation dose to a population one requires a precise knowledge of the activity of a number of radionuclides. The basis for the assessment of the dose to a population from a release of radioactivity to the environment, the estimation of the potential clinical heath effects due to the dose received and, ultimately, the implementation of countermeasures to protect the population, is the measurement of radioactive contamination in the environment after the release. It is the purpose of this book to present the facts about the presence of radionuclides in the environment, natural and man made. There is no aspect of radioactivity, which has marked the passing century, not mentioned or discussed in this book.

The book deals with various consequences of major nuclear accidents, such as in 1986 in Chernobyl and in 2011 in Fukushima. The public is extremely interested in learning more about the movements and risks posed by radiation in the environment related to food supply and food safety. Radionuclides are found in air, water, soil and even in us not only after nuclear accidents because they occur also in nature. Every day, we ingest and inhale radionuclides in our air and food and the water. This book provides a solid underpinning of the basic physical-chemistry and biogeochemistry of naturally occurring and anthrop radioactivity. The mechanisms of radioactive element transfer in the atmosphere, tropospheric and stratospheric diffusion of radioactivity, environmental contamination from accidents and the impact of atmospheric pollution on the food chain, soil and plants, are analyzed and the analytical methods are illustrated. The question of natural radioactivity concentration in building materials is addressed too. While the book contains many case studies and data for Greece, it is of general value. It contributes to the development of international environmentally safe standards and economically reasonable standard regulations based on justified radiological, social and economical legislation concepts.

Fukushima Accident presents up-to-date information on radioactivity released to the atmosphere and the ocean after the accident on the Fukushima Dai-ichi nuclear power plant, on the distribution of radionuclides in the world atmosphere and oceans, and their impact on the total environment (man, fauna, and flora). The book will evaluate and discuss the post-Fukushima situation, emphasizing radionuclide impacts on the terrestrial and marine environments, and compare it with the pre-Fukushima sources of radionuclides in the environment. The authors’ results, as well as knowledge gathered from the literature, will provide up-to-date information on the present status of the topics. Fukushima Accident is based on the environmental and nuclear research; however, the presentation will be suitable for university-level readers. 2013 PROSE Award winner in Environmental Science from the Association of American Publishers Covers atmospheric and marine radioactivity, providing information on the global atmospheric dispersion of radionuclides in the atmosphere and world oceans Examines radiation doses to the public and biota to understand the health risks to the public and ecosystems Provides information on monitoring radionuclides in the environment – information on sources of radionuclides, their temporal and spatial variations, and radionuclide levels Covers transport of radionuclides from different sources (e.g. nuclear power plants) as well as atmospheric simulations and modeling approaches

This booklet describes the environmental investigations that have been conducted with the aid of the atom since the first atomic detonation near Alamogordo, New Mexico, in 1945. The earth's mysteries, however, are not easily unlocked, and investigations of our environment with atomic tools have only begun. The story thus is one of beginnings but of beginnings that point the way, it is hoped, to a new understanding of the world in the atomic future.

Just as an environmental model typically will be composed of a number of linked sub-models, representing physical, chemical or biological processes understood to varying degrees, this volume includes a series of linked chapters exemplifying the fundamental nature of environmental radioactivity models in all compartments of the environment. Why is a book on modelling environmental radioactivity necessary? There are many reasons why such a boook is necessary, perhaps the most important that: - modelling is an often misunderstood and maligned activity and this book can provide, to a broad audience, a greater understanding of modelling power but also some of the limitations. - modellers and experimentalists often do not understand and mistrust each other's work yet they are mutually dependent, in the sense that good experimental science can direct good modelling work and vice-versa; we hope that this book can dispel mistrust and engender improved understanding. - there is an increasing reliance on model results in environmental management, yet there is also often misuse and misrepresentation of these results. This book can help to bridge the gap between unrealistic expectations of model power and the realisation of what is possible, practicable and feasible in modelling of environmental radioactivity; and finally, - modelling tools, capacity and power have increased many-fold in a relatively short period of time. Much of this is due to the much-heralded computer revolution, but much is also due to better science. It is useful to consider what gap if any still remains between what is possible and what is necessary.

The Natural Radiation Environment Symposium (NRE VII), the Seventh in the NRE series, which commenced forty years ago in 1963 at Rice University Texas, was held in Rhodes (Greece) in May 2002. During the intervening four decades the research work presented at these NRE Symposia has contributed to a deeper understanding of natural radiation and in particular of its contribution to human radiation exposures. It is clear from the quality and diversity of the 143 papers in this volume of Radioactivity in the Environment series that the study of the natural radiation environment is an active and continually expanding field of research. The papers in this volume fall into a number of main and topical research areas namely: the measurement and behaviour of natural radionuclides in the environment cosmic radiation measurement and dosimetry the external penetrating radiation field at ground level TENR (Technologically Enhanced Natural Radiation) and NORM (Naturally Occurring Radioactive Materials) studies assessment of the health effects of radon regulatory aspects of natural radiation exposures In these papers the results of many new surveys of natural radionuclide levels in the environment and of improved methods of detection are described. While some of the natural radiation sources investigated are unmodified by human activity, many accounts are given here of exposures to natural sources which have been enhanced by technology. Such TENR and NORM exposures are shown to range from activities such as mining, oil and gas exploitation, the use of industrial by-products as building materials, to space travel to name but a few. In several cases quite high doses to some individuals are shown to occur. Accounts are given here of methods to prevent and reduce exposures to such sources.

Radioactive sources such as nuclear power installations can pose a great threat to both humans and our environment. How do we measure, model and regulate such threats? Environmental Radioactivity and Emergency Preparedness addresses these topical questions and aims to plug the gap in the lack of comprehensive literature in this field. The book explores how to deal with the threats posed by different radiological sources, including those that are lost or hidden, and the issues posed by the use of such sources. It presents measurement methods and approaches to model and quantify the extent of threat, and also presents strategies for emergency preparedness, such as strategies for first-responders and radiological triage in case an accident should happen. Containing the latest recommendations and procedures from bodies such as the IAEA, this book is an essential reference for both students and academicians studying radiation safety, as well as for radiation protection experts in public bodies or in the industry.

The analysis of radionuclides in the environment became extremely important after the accident at Chernobyl in1986. The accident made scientists aware that accurate methods of radionuclide analyses are essential in order to estimate the risk to the public from released radioactivity. Methods are still being developed today because of the ongoing requirement to monitor environmental radioactivity and, to assess the radionuclide waste inventory for the recently proposed intermediate radioactive waste repository. This book brings together current developments in radioactive analyses. Environmental Radiochemical Analysis III is an authoritative, up to date review of research contributions presented at the 10th International Symposium on Environmental Radiochemical Analysis. Representing the work of leading scientists across the globe this edition provides information on: * new methods of radioanalyses * waste steams during decommissioning * radioactivity measurements in the environment * hazard assessment in decommissioning * improvements in measurement instrumentation * application of software to measurements * current IAEA activities for the ALMERA network * proficiency testing and research and development in the NDA. This exceptional work offers an insight into topical areas of research and is a key point of reference for graduates and professionals alike who work across fields involving analytical chemistry, environmental science and technology, and hazards and waste research and disposal.

Nuclear energy is the one energy source that could meet the world'sgrowing energy needs and provide a smooth transition from fossilfuels to renewable energy in the coming decades and centuries. Itis becoming abundantly clear that an increase in nuclear energycapacity will, and probably must, take place. However, nuclear energy and the use of radionuclides forcivilian and military purposes lead to extremely long-lived wastethat is costly and highly problematic to deal with. Therefore, itis critically important ot understand the environmentalimplications of radionuclides for ecosystems and human health ifnuclear energy is to be used to avoid the impending global energycrisis. The present volume of the EIC Books series addresses thiscritical need by providing fundamental information onenvironmentally significant radionuclides. The content of this book was developed in collaboration withmany of the authors of the chapters. Given the enormity of thesubject the Editor and the Authors had to be judicious in selectingthe chapters that would appropriately encompass and describe theprimary topics, particularly those that are of importance to thehealth of ecosystems and humans. The resulting chapters were chosento provide this information in a book of useful and appropriatelength. Each chapter provides fundamental information on thechemistry of the radionuclides, their occurrence and movement inthe enivornment, separation and analyses, and the technologiesneeded for their remediation and mitigation. The chapters arestructured with a common, systematic format in order to facilitatecomparions between elements and groups of elements. About EIC Books The Encyclopedia of Inorganic Chemistry (EIC) has provedto be one of the defining standards in inorganic chemistry, andmost chemistry libraries around the world have access either to thefirst of second print editon, or to the online version. Manyreaders, however, prefer to have more concise thematic volumes,targeted to their specific area of interest. This feedback from EICreaders has encouraged the Editors to plan a series of EIC Books,focusing on topics of current interest. They will appear on aregular basis, and will feature leading scholars in their fields.Like the Encyclopedia, EIC Books aims to provide both the startingresearch student and the confirmed research worker with a criticaldistillation of the leading concepts in inorganic and bioinorganicchemistry, and provide a structured entry into the fieldscovered. This volume is also available as part of Encyclopedia ofInorganic Chemistry, 5 Volume Set. This set combines all volumes published as EIC Books from 2007to 2010, representing areas of key developments in the field ofinorganic chemistry published in the Encyclopedia of InorganicChemistry. ahref="http://eu.wiley.com/WileyCDA/WileyTitle/productCd-1119994284.html"Findout more/a.

Over the years, radioactive particles have been released to the environment from nuclear weapons testing and nuclear fuel cycle operations. However, measurements of environmental radioactivity and any associated assessments are often based on the average bulk mass or surface concentration, assuming that radionuclides are homogeneously distributed as simple ionic species. It has generally not been recognised that radioactive particles present in the environment often contain a significant fraction of the bulk sample activity, leading to sample heterogeneity problems and false and/or erratic measurement data. Moreover, the inherent differences in the transport and bioavailability of particle bound radionuclides compared with those existing as molecules or ions have largely been ignored in dose assessments. There are currently no documents or international guides covering this aspect of environmental impact assessments. To fill this gap, between 2001 and 2008 the IAEA performed a Coordinated Research Programme (CRP- G4.10.03) on the 'Radiochemical, Chemical and Physical Characterisation of Radioactive Particles in the Environment' with the objective of development, adoption and application of standardised analytical techniques for the comprehensive study of radioactive particles. This IAEA-TECDOC presents the findings and achievements of the above CRP in the area of measurement and characterisation of radioactive particles in the environment.
