The purpose of this book is to present a state of art summary of current knowledge of methods of assessment of radionuclides in the terrestrial and marine environments. It cover the traditional methods of radioactivity measurements such as radiometrics techniques, but also recent developments in the mass spectrometry sector. The book starts with a short preface introducing the subject of the book, summarising content and philosophy of the book, as well as the most important historical achievements. The scientific topics are introduced by description of sampling methods, optimisation of sampling sites and sampling frequency. The recent developments in radiochemical separation methods using chromatography resins for the treatment of actinides, transuranics and other groups of radioelements are also described. No other book is available covering all aspects of environmental radioactivity measurements, although remarkable progress has been made in detection techniques over the last ten years. At present the new methods enable to carry out investigations which were not possible before, either because of lack of sensitivity or because of the fact that they required too large samples.

Environmental Radionuclides presents a state-of-the-art summary of knowledge on the use of radionuclides to study processes and systems in the continental part of the Earth’s environment. It is conceived as a companion to the two volumes of this series, which deal with isotopes as tracers in the marine environment (Livingston, Marine Radioactivity) and with the radioecology of natural and man-made terrestrial systems (Shaw, Radioactivity in Terrestrial Ecosystems). Although the book focuses on natural and anthropogenic radionuclides (radioactive isotopes), it also refers to stable environmental isotopes, which in a variety of applications, especially in hydrology and climatology, have to be consulted to evaluate radionuclide measurements in terms of the ages of groundwater and climate archives, respectively. The basic principles underlying the various applications of natural and anthropogenic radionuclides in environmental studies are described in the first part of the book. The book covers the two major groups of applications: the use of radionuclides as tracers for studying transport and mixing processes: and as time markers to address problems of the dynamics of such systems, manifested commonly as the so-called residence time in these systems. The applications range from atmospheric pollution studies, via water resource assessments to contributions to global climate change investigation. The third part of the book addresses new challenges in the development of new methodological approaches, including analytical methods and fields of applications.

Radiological Risk Assessment and Environmental Analysis comprehensively explains methods used for estimating risk to people exposed to radioactive materials released to the environment by nuclear facilities or in an emergency such as a nuclear terrorist event. This is the first book that merges the diverse disciplines necessary for estimating where radioactive materials go in the environment and the risk they present to people. It is not only essential to managers and scientists, but is also a teaching text. The chapters are arranged to guide the reader through the risk assessment process, beginning with the source term (where the radioactive material comes from) and ending with the conversion to risk. In addition to presenting mathematical models used in risk assessment, data is included so the reader can perform the calculations. Each chapter also provides examples and working problems. The book will be a critical component of the rebirth of nuclear energy now taking place, as well as an essential resource to prepare for and respond to a nuclear emergency.

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=""Findout more/a.

The basic goal of this book is to examine the complex state of radioactivity in the environment, including its sources and applications. In principle, there are two sources of environmental radioactivity, namely man-made and natural. The authors of this book set out to analyze mainly empirical aspects of the activities of both groups. On one hand, a detailed analysis of the sources releasing radionuclides into the environment by human activities should, while describing environmental pollution and its dangers, contribute to its decrease in the future. On the other hand, the analyses of natural radionuclides, as well as their influences and use in different fields, serve to complete an evaluation of the present state of environmental radioactivity. All auxiliary parts (e.g., principles of radionuclide analyses) are included to the extent necessary for understanding the basic themes. The many recent examples contained in the book will be useful in studying various problems of radioactivity in the present environment, and can help, not only in preparing, carrying out and evaluating outdoor and laboratory experiments, but also in protection of the environment and human health through analyses of possible sources of radioactive pollution. Audience: This book can be used by research workers, university professors and students in scientific and technological disciplines (e.g., nuclear physics and engineering, radioanalytical and nuclear chemistry, geology, hydrology, and archaeology), and by those involved in environmental protection and control in the nuclear industry (including nuclear weapons and nuclear safety).
