Book Description
Naturally occurring radionuclides are found throughout the earth's crust, and they form part of the natural background of radiation to which all humans are exposed. Many human activities-such as mining and milling of ores, extraction of petroleum products, use of groundwater for domestic purposes, and living in houses-alter the natural background of radiation either by moving naturally occurring radionuclides from inaccessible locations to locations where humans are present or by concentrating the radionuclides in the exposure environment. Such alterations of the natural environment can increase, sometimes substantially, radiation exposures of the public. Exposures of the public to naturally occurring radioactive materials (NORM) that result from human activities that alter the natural environment can be subjected to regulatory control, at least to some degree. The regulation of public exposures to such technologically enhanced naturally occurring radioactive materials (TENORM) by the US Environmental Protection Agency (EPA) and other regulatory and advisory organizations is the subject of this study by the National Research Council's Committee on the Evaluation of EPA Guidelines for Exposures to Naturally Occurring Radioactive Materials.

Book Description
The Commission of the European Communities has contracted this study with the Radiation and Nuclear Safety Authority (STUK). The aim of the study is to provide the Commission information about natural radiactivity in building materials and in industrial by-products used as raw materials in building material industry. Furthermore the aim is to enquire existing regulations in the Member States and to make a proposal for a common approach for possible inclusion of control of radioactivity of building materials in EC regulations.

Book Description
This report assesses the levels and effects of exposure to ionizing radiation. Scientific findings underpin radiation risk evaluation and international protection standards. This report comprises a report with two underpinning scientific annexes. The first annex recapitulates and clarifies the philosophy of science as well as the scientific knowledge for attributing observed health effects in individuals and populations to radiation exposure, and distinguishes between that and inferring risk to individuals and populations from an exposure. The second annex reviews the latest thinking and approaches to quantifying the uncertainties in assessments of risk from radiation exposure, and illustrates these approaches with application to examples that are highly pertinent to radiation protection.

Book Description
The handbook centers on detection techniques in the field of particle physics, medical imaging and related subjects. It is structured into three parts. The first one is dealing with basic ideas of particle detectors, followed by applications of these devices in high energy physics and other fields. In the last part the large field of medical imaging using similar detection techniques is described. The different chapters of the book are written by world experts in their field. Clear instructions on the detection techniques and principles in terms of relevant operation parameters for scientists and graduate students are given.Detailed tables and diagrams will make this a very useful handbook for the application of these techniques in many different fields like physics, medicine, biology and other areas of natural science.

Book Description
The aim of radiation protection standards is to make the radiation workplace as safe as is humanly possible. The gradual evolution over the last 20 years has been towards a more precise definition of the limits for occupational exposure. These have been created not only in terms of short-term effects but also more importantly in terms of long-term risks involving such problems as the potential for carcinogenesis and genetic change. In the United States the National Committee for Radiation Protection has recom mended that 5 rems (50 mSv) should remain as the maximum permissible dose equiva lent for total body exposure. This would represent the sum of internal and external ex posure and should be regarded as the upper limit allowed. The community of radiation users is required to conduct its operations in such a man ner that the absolute value of the individual's dose equivalent in rems does not exceed his age in years. There should be additional limits for tissues and organs based on short term effects. Therefore, individual organs are limited to dose equivalents low enough to ensure that the dose threshold values are not exceeded.

Book Description
This Safety Guide provides recommendations on meeting the requirements established in the IAEA International Basic Safety Standards, for protection of the public against exposure indoors due to natural sources of radiation. Guidance is provided on the application of the requirements for justification and optimization of protection by national authorities in considering control of natural sources of radiation indoors such as radon and radionuclides of natural origin in materials used for the construction of dwellings, offices, industrial premises and other buildings. The Safety Guide provides recommendations and guidance to be followed by the regulatory body and by other authorities and organizations with responsibilities in relation to exposure to radiation from natural sources.

Book Description
"Our world has been radioactive ever since! Humans are primarily exposed to natural radiation from the sun, cosmic rays, and naturally-occurring radionuclides found in the Earth's crust. Besides the natural radioactivity, industries, which produce radioactive wastes during their normal operations or during their dismantling and decommissioning processes, do contaminate the environment through the release of radionuclides into the air, soil and water. Among them, nuclear power plants, NORM (Naturally Occurring Radioactive Materials) related industries, hospitals, radionuclide production facilities, uranium mining and other nuclear facilities, along with radioactive/nuclear disposal sites are a potential source of environmental contamination by emission/discharging of natural/artificial radionuclides through water, air and soil to the other environmental compartments like plants, animals and foods. In a word, everything that makes our existence! The book "Radionuclides: Properties, Behavior and Potential Health Effects" is a comprehensive overview of some information on radiation in the environment and human exposure to radioactivity. This book highlights the sources, properties, behaviors, and biological and ecological effects of radioactivity from both natural and anthropogenic sources. The emphasis is on the environmental aspects of radionuclides and their eventual effects on biota, particularly humans"--

Book Description
Assuming a basic knowledge of calculus, differential equations and some atomic physics, this classic bestseller enables students to select the proper detector, analyze the results of counting experiments, and perform radiation measurements following proper health physics procedures. Examples and problems in each chapter ensure that students understand the concepts presented. The book cover long-range alpha detector LRAD, pure geranium detectors, magnetic and electrostatic spectrometers, position-sensitive detectors, the LSL-M2 unfolding code, compensated ion chambers, self-powered neutron detectors, new protection guides, and exposure limits. A solutions manual is available for qualifying instructors.
