This book discusses important fundamentals of radiation safety with specific details on dose units, calculations, measuring, and biological effects of ionizing radiation. The author covers different exposure situations and their requirements, and relevant legislation and regulations governing radiation safety. The book also examines radioactive waste management, the transport of radioactive materials, emergency planning and preparedness and various examples of radiation protection programs for industrial, medical, and academic applications.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
This book lays the foundations for you to understand all that you always wanted to know about radioactivity. It begins by setting out essential information about the structure of matter, how radiation occurs and how it can be measured. It goes on to explore the substantial benefits of radioactivity through its many applications, and also the possible risks associated with its use. The field of radioactivity is explained in layman's terms, so that everybody who is interested can improve their understanding of issues such as nuclear power, radiation accidents, medical applications of radiation and radioactivity from the environment. Everything is radioactive. There is natural radioactivity in the homes that we live in, the food that we eat and the air that we breath. For over 100 years, people have recognised the potential for radioactivity to help solve problems and improve our standard of living. This has led to the creation of radioactivity levels in some places that are much higher than naturally-occurring background levels. Such high levels of radiation can be harmful to people and the environment, so there is a clear need to manage this potential harm and to make the risk worth the benefits mankind can achieve from radioactive materials.
This is volume two of a comparative analysis of nuclear waste governance and public participation in decision-making regarding the storage and siting of high-level radioactive waste and spent fuel in different countries. The contributors examine both the historical and current approaches countries have taken to address the wicked challenge of nuclear waste governance. The analyses discuss the regulations, technology choices, safety criteria, costs and financing issues, compensation schemes, institutional structures, and approaches to public participation found in each country.
Homer speaks of lightning bolts after which 'a grim reek of sulphur bursts forth' and the air was '?lled with reeking brimstone'. (Homer 3000 BC). The odour was not actually the smell of sulphur dioxide associated with burning sulphur, but rather was the ?rst recorded detection of the presence of another strong odour, that of ozone (O ) in Earth's atmosphere. These molecules were formed by the passage of 3 lightning through the air, created by splitting the abundant molecular oxygen (O ) 2 molecules into two, followed by the addition of each of the free O atoms to another O to form the triatomic product. In fact, most of the ozone molecules present 2 in the atmosphere at any time have been made by this same two-step splitti- plus-combination process, although the initiating cause usually begins with very energetic solar ultraviolet (UV) radiation rather than lightning. Many thousands of years later, the modern history of ozone began with its synthesis in the laboratory of H. F. Schonbein in 1840 (Nolte 1999), although the positive con?rmation of its three-oxygen atom chemical formula came along sometime later. Scienti?c interest in high-altitude stratospheric ozone dates back to 1881 when Hartley measured the spectrum of ozone in the laboratory and found that its ability to absorb UV light extended only to 293nm at the long wavelength end (Hartley 1881a).
This book is the collection of papers from the latest International Uranium Mining and Hydrogeology Conference (UMH VII) held in September 2014, in Freiberg, Germany. It is divided to five sessions: Uranium Mining, Uranium and Phosphates, Clean-up technologies for water and soil. Uranium and daughter nuclides and basic research and modeling. Each session covers a wide range of related topic and provides readers with up to date research and solutions on those matters.
This book provides essential background knowledge on a wide range of hydrological processes governing contaminant transport from soil to surface water across a range of scales, from hillslope to watershed. The mathematical description of these processes is based on both well-known and unique analytical solutions of different initial and boundary problems (primarily using methods from the kinematic wave theory and the reservoir/lumped-parameter concept), supported by numerical modelling studies. Some research topics, in particular several case studies, are illustrated by monitoring and experimental data analysis to show the importance of the research's applications in environmental practice and environmental education. Specific results concern the recognition of: (a) the effect of transient rainfall-runoff-infiltration partitioning on the chemical response of drainage areas to excess precipitation under certain field conditions related to the soil, hillslope characteristics, and contaminant properties; (b) soil erosion as a key factor that enhances the potential of adsorbed chemical transport in runoff; and (c) common tendencies in radionuclide behaviour in the near-surface environment contaminated by radioactive fallout from the Chernobyl (1986), Fukushima (2011) and the less known Kyshtym (1957) accidents, as well as from nuclear weapon tests in the atmosphere since 1952. The book's goal is to provide a conceptual foundation enabling readers to apply scientific knowledge to solve practical problems in environmental hydrology and radiology. More specifically, the book presents the state-of-the-art approaches that scientists and natural resources experts need in order to significantly improve the prediction of changes in the soil-water system chemistry due to human activities.
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.
This book summarizes major aspects of the evolution of South American metatherians, including their epistemologic, phylogenetic, biogeographic, faunal, tectonic, paleoclimatic, and metabolic contexts. A brief overview of the evolution of each major South American lineage ("Ameridelphia", Sparassodonta, Didelphimorphia, Paucituberculata, Microbiotheria, and Polydolopimorphia) is provided. It is argued that due to physiological constraints, metatherian evolution closely followed the conditions imposed by global temperatures. In general terms, during the Paleocene and the early Eocene multiple radiations of metatherian lineages occurred, with many adaptive types exploiting insectivorous, frugivorous, and omnivorous adaptive zones. In turn, a mixture of generalized and specialized types, the latter mainly exploiting carnivorous and granivorous-folivorous adaptive zones, characterized the second half of the Cenozoic. In both periods, climate was the critical driver of their radiation and turnovers.
Over the past few decades, mankind has observed an unprecedented and remarkable growth in industry, resulting in a more prosperous lifestyle for peoples of many countries. In developing countries, however, explosive industrial growth is just now beginning to raise the living standards of the people. Most industries, especially in these developing countries, are still powered by the burning of fossil fuels; con- quently, a lack of clean energy resources has caused environmental pollution on an unprecedented large and global scale. Toxic wastes have been relentlessly released into the air and water leading to serious and devastating environmental and health problems while endangering the planet and life itself with the effects of global warming. To address these urgent environmental issues, new catalytic and photocatalytic processes as well as open-atmospheric systems are presently being developed that can operate at room temperature while being totally clean and ef?cient and thus environmentally harmonious. Essential to technologies harnessing the abundant solar energy that reaches the earth are the highly functional photocatalytic proce- es that can utilize not only UV light, but also visible light.
With the dissolution of the Soviet Union the nuclear threats facing the world are constantly evolving and have grown more complex since the end of the Cold War. The diversion of complete weapon systems or nuclear material to rogue nations and terrorist organizations has increased. The events of the past years have proved the necessity to reevaluate these threats on a level never before considered. In recognition that no single country possesses all of the answers to the critical scientific, institutional and legal questions associated with combating nuclear and radiological terrorism, the NATO Advanced Research Workshop on "Preparedness for Nuclear and Radiological Threats" and this proceeding was structured to promote wide-ranging, multi-national exploration of critical technology needs and underlying scientific challenges to reducing the threat of nuclear/radiological terrorism; to illustrate through country-specific presentations how resulting technologies were used in national programs; and to outline the role of legal, policy and institutional frameworks in countering nuclear/ radiological terrorism. One key outcome of this book is better understanding of the interdependent contributions from across the international community of the scientific and technological components and the legal, policy and institutional components to combating nuclear and radiological threats.
This volume examines the national plans that ten Euratom countries plus Switzerland and the United States are developing to address high-level radioactive waste storage and disposal. The chapters, which were written by 23 international experts, outline European and national regulations, technology choices, safety criteria, monitoring systems, compensation schemes, institutional structures, and approaches to public involvement. Key stakeholders, their values and interests are introduced, the responsibilities and authority of different actors considered, decision-making processes are analyzed as well as the factors influencing different national policy choices. The views and expectations of different communities regarding participatory decision making and compensation and the steps that have been or are being taken to promote dialogue and constructive problem-solving are also considered.
A groundbreaking narrative of how the United States offered the promise of nuclear technology to the developing world and its gamble that other nations would use it for peaceful purposes. After the Second World War, the United States offered a new kind of atom that differed from the bombs that destroyed Hiroshima and Nagasaki. This atom would cure diseases, produce new foods, make deserts bloom, and provide abundant energy for all. It was an atom destined for the formerly colonized, recently occupied, and mostly non-white parts of the world that were dubbed the "wretched of the earth" by Frantz Fanon. The "peaceful atom" had so much propaganda potential that President Dwight Eisenhower used it to distract the world from his plan to test even bigger thermonuclear weapons. His scientists said the peaceful atom would quicken the pulse of nature, speeding nations along the path of economic development and helping them to escape the clutches of disease, famine, and energy shortfalls. That promise became one of the most misunderstood political weapons of the twentieth century. It was adopted by every subsequent US president to exert leverage over other nations' weapons programs, to corner world markets of uranium and thorium, and to secure petroleum supplies. Other countries embraced it, building reactors and training experts. Atomic promises were embedded in Japan's postwar recovery, Ghana's pan-Africanism, Israel's quest for survival, Pakistan's brinksmanship with India, and Iran's pursuit of nuclear independence. As The Wretched Atom shows, promoting civilian atomic energy was an immense gamble, and it was never truly peaceful. American promises ended up exporting violence and peace in equal measure. While the United States promised peace and plenty, it planted the seeds of dependency and set in motion the creation of today's expanded nuclear club.
This edited book provides an insight into the new approaches, challenges and opportunities that characterise open source intelligence (OSINT) at the beginning of the twenty-first century. It does so by considering the impacts of OSINT on three important contemporary security issues: nuclear proliferation, humanitarian crises and terrorism.
Looking at national peace organizations alongside lesser-known protest collectives, this book argues that anti-nuclear activists encountered familiar challenges common to other social movements of the late twentieth century.
The sharing of nuclear weapons technology between states is unexpected, because nuclear weapons are such a powerful instrument in international politics, but sharing is not rare. This book proposes a theory to explain nuclear sharing and surveys its rich history from its beginnings in the Second World War.
The atomic age was described as one that might soon end in the destruction of human civilization, but from the beginning, utopian images were attached to it as well. This book compares representations of nuclear power in popular media from around the world to to trace divergences, convergences, and exchanges.
The complexity of the twenty-first century threat landscape contrasts markedly with the bilateral nuclear bargaining context envisioned by classical deterrence theory. Nuclear and conventional arsenals continue to develop alongside anti-satellite programs, autonomous robotics or drones, cyber operations, biotechnology, and other innovations barely imagined in the early nuclear age. The concept of cross-domain deterrence (CDD) emerged near the end of the George W. Bush administration as policymakers and commanders confronted emerging threats to vital military systems in space and cyberspace. The Pentagon now recognizes five operational environments or so-called domains (land, sea, air, space, and cyberspace), and CDD poses serious problems in practice. In Cross-Domain Deterrence, Erik Gartzke and Jon R. Lindsay assess the theoretical relevance of CDD for the field of International Relations. As a general concept, CDD posits that how actors choose to deter affects the quality of the deterrence they achieve. Contributors to this volume include senior and junior scholars and national security practitioners. Their chapters probe the analytical utility of CDD by examining how differences across, and combinations of, different military and non-military instruments can affect choices and outcomes in coercive policy in historical and contemporary cases.
Biophysics is the science of physical principles underlying all processes of life, including the dynamics and kinetics of biological systems. This fully revised 2nd English edition is an introductory text that spans all steps of biological organization, from the molecular, to the organism level, as well as influences of environmental factors. In response to the enormous progress recently made, especially in theoretical and molecular biophysics, the author has updated the text, integrating new results and developments concerning protein folding and dynamics, molecular aspects of membrane assembly and transport, noise-enhanced processes, and photo-biophysics. The advances made in theoretical biology in the last decade call for a fully new conception of the corresponding sections. Thus, the book provides the background needed for fundamental training in biophysics and, in addition, offers a great deal of advanced biophysical knowledge.
An exploration of how and why Japan, South Korea, Taiwan, China and India have initiated and developed nuclear energy programs and what challenges they face today. Were the nuclear programmes driven by the low energy endowment, a desire to pursue international prestige, national security concerns, environmental pollution or economic development?
In 2002 Finnish Parliament decided to permit further construction of nuclear power after decades of long societal struggle. This book analyzes the major phases of the decision-making process. It is an excellent guide to understanding energy and climate policy in Finland and thus the main ideas behind the renewal of nuclear power in Europe.
The volume Radiological Protection is not only a compilation of numerical data and functional relationships for practical purposes. Rather a comprehensive accompanying text is intended to impart to the scientific or professional user of Radiological Protection both data, the concepts and scientific bases of the discipline devoted to prevention of health risks to man from exposure to ionizing radiations and radionuclides. It contains contributions of experts internationally qualified in scientific disciplines or subjects such as radiation physics, biology and medicine, external and internal dosimetry of ionizing radiation and radionuclides, decontamination and decorporation of radionuclides, physical and biological measuring techniques, assessment of radiation shielding (restricted to an extent being necessary for completion of tasks of practical radiological protection, specifically in the field of lower energies). The CD-ROM delivered with the hardcopy of the volume contains the full text of the volume and in addition information and data, which would be beyond the scope of the printed version, within the interactive programme SISy (for MS-Windows only). These refer e.g. to decay data of radionuclides or normalized excretion functions for monitoring workers by quantitative assessment of intakes of radionuclides and calculation of resulting doses.
The de-escalation of a nuclear crisis is one of the major issues facing humankind. This book examines how nations in crises might successfully move back from the brink of nuclear war and how confidence-building measures might help and hinder the de-escalatory process.
Viewed by experts as being on the threshold of acquiring nuclear weapons, Argentina and Brazil have recently taken steps to assure each other their nuclear programs are entirely peaceful. This reports on a 1989 conference that anticipated these events and explored the approaches being taken today.
The contributors to this text discuss the cases for and against the reprocessing of spent reactor fuel elements to remove the plutonium from them. |
