Download or read book Radioecology written by R. J. Pentreath and published by Cambridge University Press. This book was released on 2021-08-12 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural radiation arises from many sources, from the unstable atoms within our own bodies and in the materials around us, from the Sun, and even from beyond the Solar System. Additional sources include the legacy of testing nuclear weapons, nuclear waste, and nuclear accidents. All these sources have provided means of dating environmental materials and tracing the movements of substances through land, sea, and air. But ionising radiation also interacts with DNA, which has led to a remarkable range of studies to examine how and how quickly these unstable atoms are accumulated by both humans and biota, and their various effects on both. Providing an overview of the sources, uses and impacts of ionising radiation in the environment, and the frameworks developed to manage exposures to them, this is a valuable reference for graduate students and researchers interested in radioecology, environmental science and radiological protection.

Download or read book Radionuclides in the Environment written by David A. Atwood and published by John Wiley & Sons. This book was released on 2013-02-19 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear energy is the one energy source that could meet the world's growing energy needs and provide a smooth transition from fossil fuels to renewable energy in the coming decades and centuries. It is becoming abundantly clear that an increase in nuclear energy capacity will, and probably must, take place. However, nuclear energy and the use of radionuclides for civilian and military purposes lead to extremely long-lived waste that is costly and highly problematic to deal with. Therefore, it is critically important ot understand the environmental implications of radionuclides for ecosystems and human health if nuclear energy is to be used to avoid the impending global energy crisis. The present volume of the EIC Books series addresses this critical need by providing fundamental information on environmentally significant radionuclides. The content of this book was developed in collaboration with many of the authors of the chapters. Given the enormity of the subject the Editor and the Authors had to be judicious in selecting the chapters that would appropriately encompass and describe the primary topics, particularly those that are of importance to the health of ecosystems and humans. The resulting chapters were chosen to provide this information in a book of useful and appropriate length. Each chapter provides fundamental information on the chemistry of the radionuclides, their occurrence and movement in the enivornment, separation and analyses, and the technologies needed for their remediation and mitigation. The chapters are structured with a common, systematic format in order to facilitate comparions between elements and groups of elements. About EIC Books The Encyclopedia of Inorganic Chemistry (EIC) has proved to be one of the defining standards in inorganic chemistry, and most chemistry libraries around the world have access either to the first of second print editon, or to the online version. Many readers, however, prefer to have more concise thematic volumes, targeted to their specific area of interest. This feedback from EIC readers has encouraged the Editors to plan a series of EIC Books, focusing on topics of current interest. They will appear on a regular basis, and will feature leading scholars in their fields. Like the Encyclopedia, EIC Books aims to provide both the starting research student and the confirmed research worker with a critical distillation of the leading concepts in inorganic and bioinorganic chemistry, and provide a structured entry into the fields covered. This volume is also available as part of Encyclopedia of Inorganic Chemistry, 5 Volume Set. This set combines all volumes published as EIC Books from 2007 to 2010, representing areas of key developments in the field of inorganic chemistry published in the Encyclopedia of Inorganic Chemistry.

Download or read book Radionuclide Contamination and Remediation Through Plants written by Dharmendra Kumar Gupta and published by Springer. This book was released on 2014-07-14 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the mechanistic (microscopic) understanding of radionuclide uptake by plants in contaminated soils and potential use of phytoremediation. The key features concern radionuclide toxicity in plants, how the radioactive materials are absorbed by plants, and how the plants cope with the toxic responses. The respective chapters examine soil classification, natural plant selection, speciation of actinides, kinetic modeling, and case studies on cesium uptake after radiation accidents. Radionuclide contaminants pose serious problems for biological systems, due to their chemical toxicity and radiological effects. The processes by which radionuclides can be incorporated into vegetation can either originate from activity interception by external plant surfaces (either directly from the atmosphere or from resuspended material), or through uptake of radionuclides via the root system. Subsequent transfer of toxic elements to the human food chain is a concrete danger. Therefore, the molecular mechanisms and genetic basis of transport into and within plants needs to be understood for two reasons: The effectiveness of radionuclide uptake into crop plants – so-called transfer coefficient – is a prerequisite for the calculation of dose due to the food path. On the other hand, efficient radionuclide transfer into plants can be made use of for decontamination of land – so-called phytoremediation, the direct use of living, green plants for in situ removal of pollutants from the environment or to reduce their concentrations to harmless levels.

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.

Download or read book Sampling of agricultural soils and plants for radioactivity analysis written by Dercon, G., Lee Zhi Yi, A., Fesenko, S., Heng, L. and published by Food & Agriculture Org.. This book was released on 2022-06-02 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The evaluation of radioactive releases to the environment is important for the support of sustainable development of agriculture, due to the potential for released radioactivity to enter food chain. The impact of radionuclides on the food chains are normally assessed by means of measurements of radioactivity in environmental samples, which include soils, feedstuffs, foodstuffs, and water. Sampling of agricultural soils and food, as well as measurement of various radionuclides for radioactivity requires efficient, cheap, effective and easily implemented techniques. The lack of such techniques may prevent the development of national infrastructures in providing the required level of food safety. This document provides the standard operating procedures (SOPs) for sampling and measurements of radionuclides in agriculture. It also includes an overview of the techniques relevant for agricultural soil and crops. Supplementary techniques such as the assessment of radiocaesium mobility in soils are also presented. The document is intended for individuals and authorities dealing with sampling and measurement of radionuclides in agricultural environments, and answered the many request for assistance from the IAEA Members in radionuclide measurements in agricultural soils and food items.

Download or read book Tropical Radioecology written by J.R. Twining and published by Newnes. This book was released on 2012-12-31 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Radioecology is a guide to the wide range of scientific practices and principles of this multidisciplinary field. It brings together past and present studies in the tropical and sub-tropical areas of the planet, highlighting the unique aspects of tropical systems. Until recently, radioecological models for tropical environments have depended upon data derived from temperate environments, despite the differences of these regions in terms of biota and abiotic conditions. Since radioactivity can be used to trace environmental processes in humans and other biota, this book offers examples of studies in which radiotracers have been used to assess biokinetics in tropical biota. - Features chapters, co-authored by world experts, that explain the origins, inputs, distribution, behaviour, and consequences of radioactivity in tropical and subtropical systems. - Provides comprehensive lists of relevant data and identifies current knowledge gaps to allow for targeted radioecological research in the future. - Integrates radioecological information into the most recent radiological consequences modelling and best-practice probabilistic ecological risk analysis methodology, given the need to understand the implications of enhanced socio-economic development in the world's tropical regions.

Download or read book Nuclear Power and the Environment written by R M Harrison and published by Royal Society of Chemistry. This book was released on 2011-08-03 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: The environmental implications of generating electric power from nuclear fission have been a matter of concern since the construction of the earliest nuclear reactors and power stations in the 1950s. After two or more decades of construction of nuclear power stations, this ceased in many countries, largely as a result of concerns for the environment and human health. However, the pressing need to reduce greenhouse gas emissions is leading many countries to plan extensive new programmes of construction of nuclear power stations which serves to re-emphasise concerns over environmental impacts. Volume 32 of the Issues in Environmental Science and Technology series is concerned with reviewing the political and social context for nuclear power generation, the nuclear fuel cycles and their implications for the environment. Known issues of nuclear accidents, the legacy of contaminated land and low level waste, and the decommissioning of nuclear sites are considered together with a more forward look at the deep geological disposal of high level waste and the pathways of radioactive substances in the environment and their implications for human and non-human organisms. This topical work will be of interest to scientists and policy makers working within this field or related areas as well as advanced students.

Download or read book Nuclear and Radiological Emergencies in Animal Production Systems Preparedness Response and Recovery written by Ivancho Naletoski and published by Springer Nature. This book was released on 2021-05-31 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access volume explains how major nuclear and radiological emergencies (NREs) can have implications at local, national and international level. The response to NREs requires a competent decision-making structure, clear communication and effective information exchange. National veterinary services have the responsibility to plan, design and manage animal production system in their countries. These activities cover animal health, animal movement control, production control and improvement, and control of the products of animal origin before their placement on the market. Release of radionuclides after NREs can cause substantial contamination in the animal production systems. Critical responsibility of veterinary authorities is therefore to prevent such contamination, establish early response mechanisms to mitigate the consequences and prevent placement of contaminated products of animal origin on the market for human consumption. This work summarizes the critical technical points for effective management of NREs for national veterinary services.

Download or read book Radiological Issues for Fukushima s Revitalized Future written by Tomoyuki Takahashi and published by Springer. This book was released on 2016-01-12 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book overviews environmental issues 4 years after the Fukushima nuclear accident, covering a wide range of areas related to radiation and radioactivity. The topics discussed are necessary to make clear the relationship between the results of research and Fukushima’s revitalized future. The chapters are divided into four parts: Part 1 presents the identification of radionuclides in soil and migration of radionuclides in the terrestrial environment; Part 2 describes the safety decontamination system and treatment of radioactive waste; Part 3 explains the development of the system of measurement of environmental radiation and evaluation of external exposure; and Part 4 discusses the identification of radionuclides in farm products, control of root uptake, identification of decreasing radionuclides by food processing, and evaluation of internal exposure. Since the accident at the Tokyo Electric Power Company's Fukushima Daiichi nuclear power station in 2011, gradual steps have been taken toward environmental recovery in the area. However, there are still many issues that need to be tackled in order to achieve the full revitalization of Fukushima. These issues encompass many different disciplines such as economics, psychology, and sociology. In this kind of situation, the role of science in relation to radiation and radioactivity is especially important. This book aims to contribute to planning countermeasures against nuclear disasters in the future. It will be of particular interest to governmental officials who are engaged with the Fukushima nuclear accident; researchers, including those in international sectors, who are interested in radiological issues; and those who need comprehensive and reliable information about the Fukushima accident.

Download or read book Fish Physiology Homeostasis and Toxicology of Essential Metals written by and published by Academic Press. This book was released on 2011-06-28 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostasis and Toxicology of Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. The companion volume, Homeostasis and Toxicology of Non-Essential Metals, Volume 31B, covers metals that have no known nutritive function in fish at present, but which are toxic at fairly low levels, such as Ag, Al, Cd, Pb, Hg, As, Sr, and U. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers. - All major essential metals of interest are covered in metal-specific chapters - Each metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metal - A common format is featured throughout this two volume edition
