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.

This book provides a readable and thought-provoking analysis of the issues surrounding nuclear fuel reprocessing and fast-neutron reactors, including discussion of resources, economics, radiological risk and resistance to nuclear proliferation. It describes the history and science behind reprocessing, and gives an overview of the status of reprocessing programmes around the world. It concludes that such programs should be discontinued. While nuclear power is seen by many as the only realistic solution to the carbon emission problem, some national nuclear establishments have been pursuing development and deployment of sodium-cooled plutonium breeder reactors, and plutonium recycling. Its proponents argue that this system would offer significant advantages relative to current light water reactor technology in terms of greater uranium utilization efficiency, and that separating out the long-lived plutonium and other transuranics from spent fuel and fissioning them in fast reactors would greatly reduce the duration of the toxicity of radioactive waste. However, the history of efforts to deploy this system commercially in a number of countries over the last six decades has been one of economic and technical failure and, in some cases, was used to mask clandestine nuclear weapon development programs. Covering topics of significant public interest including nuclear safety, fuel storage, environmental impact and the spectre of nuclear terrorism, this book presents a comprehensive analysis of the issue for nuclear engineers, policy analysts, government officials and the general public. "Frank von Hippel, Jungmin Kang, and Masafumi Takubo, three internationally renowned nuclear experts, have done a valuable service to the global community in putting together this book, which both historically and comprehensively covers the "plutonium age" as we know it today. They articulate in a succinct and clear manner their views on the dangers of a plutonium economy and advocate a ban on the separation of plutonium for use in the civilian fuel cycle in view of the high proliferation and nuclear-security risks and lack of economic justification." (Mohamed ElBaradei, Director General, International Atomic Energy Agency (1997-2009), Nobel Peace Prize (2005)) "The 1960s dream of a 'plutonium economy' has not delivered abundant low-cost energy, but instead has left the world a radioactive legacy of nuclear weapons proliferation and the real potential for nuclear terrorism. Kang, Takubo, and von Hippel explain with power and clarity what can be done to reduce these dangers. The governments of the remaining countries whose nuclear research and development establishments are still pursuing the plutonium dream should pay attention." (Senator Edward Markey, a leader in the US nuclear-disarmament movement as a member of Congress since 1976) "The authors have done an invaluable service by putting together in one place the most coherent analysis of the risks associated with plutonium, and the most compelling argument for ending the practice of separating plutonium from spent fuel for any purpose. They have given us an easily accessible history of the evolution of thinking about the nuclear fuel cycle, the current realities of nuclear power around the world and, arguably most important, a clear alternative path to deal with the spent fuel arising from nuclear reactors for decades to centuries to come."

The only book available in English to focus exclusively on the subject, Environmental Applications of Ionizing Radiation belongs in the working library of every aspiring or practicing scientist or engineer concerned with environmental pollution.

Radiation has long been used in food processing, medical device sterilization, and polymer production, but only recently has it begun to be widely accepted as a valued component in environmental cleanup initiatives. The growing popularity of radiation as a means of neutralizing both natural and synthetic contaminants is due, in great part, to impressive results recently achieved by researchers worldwide using ionizing radiation methods, especially those involving electron beam techniques. Despite these many successes, there continues to be a conspicuous poverty of professional references on the subject. Environmental Applications of Ionizing Radiation fills that gap.

Environmental Applications of Ionizing Radiation brings together contributions by more than 100 leading scientists from the Americas, Europe, and Asia. The first English-language text devoted exclusively to this exciting growth area, it affords readers a unique opportunity to acquaint themselves with state-of-the-art applications of ionizing radiation for solving environmental remediation problems.

This highly successful manual has served for nearly three decades as the definitive guide to the safe use of radioactive materials. Completely revised and updated, the fourth edition presents a new dimension by adding coverage of nonionizing radiation, and is thus concerned with the entire field of radiation protection.

The author takes the novel approach of introducing the whole range of energies possessed by particles and electromagnetic waves at the beginning of the text, thus integrating coverage of ionizing and nonionizing radiation rather than considering them as two separate disciplines. He goes on to cover the entire spectrum of radiation sources, including radionuclides, x-ray machines, accelerators, nuclear reactors, power lines, microwave towers, and cellular phones.

With its expanded coverage, including a broader focus on public health issues, this new volume will serve as an important training and reference resource, not only for research scientists, physicians, and engineers, but for regulatory officials, attorneys, engineers, and environmental health and safety professionals. The breadth of citations alone makes this resource invaluable.

A comprehensive review of non-ionizing radiation and its public health and environmental risks, for researchers, policy makers, and laymen This book explains the characteristics of all forms of electromagnetic non-ionizing radiation (NIR) and analyzes the relationship between exposure and its biological effects, as well as the known dose-response relationships associated with each. Taking a uniquely holistic approach to the concept of health that builds upon the WHO definition to include not only absence of disease, but the physical, mental and social well-being of individuals and the population, it reviews established and potential risks and protections, along with regulatory issues associated with each. The risks to public health of NIR, whether in the form of UV light, radio waves from wireless devices, or electric and magnetic fields associated with electrical power systems, is currently a cause of great concern among members of the public and lawmakers. But in order to separate established science from speculation and make informed decisions about how to mitigate the risks of NIR and allocate precious resources, policymakers, manufacturers, and individuals need a comprehensive source of up-to-date information based on the current scientific evidence. Written by a team of experts in their fields, this book is that source. Among other things, it: * Summarizes scientific findings on the safety of different forms of NIR and the rationale behind current standards * Describes devices for monitoring NIR along with the established and potential hazards of each form * Explores proper protections against UV light and lasers, RF radiation, ELF fields and other forms of NIR * Discusses how to avoid injuries through occupational training or public awareness programs, and how to perform medical assessments in cases of suspected NIR injuries * Considers how to decide whether or not to spend money on certain mitigation measures, based on cost-benefit analyses Offering expert reviews and analyses of the latest scientific findings and public policy issues concerning the risks to public health and the environment of NIR, Non-ionizing Radiation Protection is an indispensable source of information for manufacturers, government regulators, and regulatory agencies, as well as researchers, concerned laypersons, and students.

Different applications and uses of light energy have emerged over the last few years in many different fields such as in medicine, material science, energy and biochemistry. New and exciting applications of light-controlled processes have become practical in the diagnosis and treatment of diseases, the preparation and use of functional materials, the storage of solar energy and the control of biological properties. Many of these applications are based on a very simple chemical step: a photoisomerization. The isomerization of a chemical double bond allows for the control with extreme spatial and temporal resolution of complex systems. Nature offers different examples of very complex functions that are initiated by this type of simple chemical. Upon photon absorption, the light energy can be used to induce a chemical (geometrical) change that influences the protein environment that triggers a specific signal or function. Inspired by these amazing and extremely efficient processes, many efforts have been devoted to the modification of natural systems and to the design of new applications, using simple and tunable photoisomerizations. Accordingly, the preparation of photoactive molecular devices based on photoisomerizations and the use of these species in different applications is now a very active scientific field, with profound implications in our everyday lives. In this book, the fundamental aspects of the photoisomerization of many different chemical structures containing C=C, N=N and C=N double bonds is covered. Different experimental and computational tools used to study these processes are discussed and some specific applications of different compounds are presented.

Appropriate sampling and sample preparation are the first steps to ensure the quality and effective use of the measurements and this publication provides comprehensive detail on the necessary steps.

There is the conjuncture that 2012 is a special year in the history of physics, that cannot go unobserved without celebration: 100 years of cosmic ray discovery, the 75th anniversary of Muon discovery and 70 years of the discovery of relativistic solar particles (Ground Level Enhancements). Several symposiums have been held in this regard, among which can be mentioned is that of the one held in Pollau, Austria in May 2012. There is need of a book that pays homage to these historical discoveries. The aim of this book is to collect some typical papers written for researchers of the international cosmic ray community that many scientists and students would like to have in their libraries. The main market for this book are universities and research institutes throughout the world, and mainly in countries where there is an old tradition in cosmic ray research: Europe, USA, Mexico, Canada, East Europe (mainly Russia), Japan, Australia, China, etc. It should also be of interest in scientific societies, professional organisations, or other groups relevant to the several fields of particle physics: eg: The Victor F Hess Society and the European Physical Society/History of Physics Group (EPS/HoP), COSPAR, IUGG, American Geophysical Union, Union Geofisica Mexicana, and others.
