Book excerpt: Most building materials contain naturally occurring radioactive elements, the most important of which are potassium 40K and the members of two natural radioactive series, which can be represented by the isotopes of thorium 232Th and radium 226Ra. The assessment of population exposures due to indoor radiation is very important and therefore knowledge of the concentrations of natural radionuclides in construction materials is required. Construction materials are derived from both natural sources and waste products and also from industry products. Although building materials act as a source of radiation to the inhabitants in their dwellings, they also have the role of a shield against outdoor radiation. Thus, the knowledge of radioactivity in building materials is important to estimate the radiological hazards to human health. Knowledge of basic radiological parameters such as radioactive contents and attenuation coefficients in building materials is important in the assessment of possible radiation exposure of the population as most people spend about 80% of their life inside houses and offices. This knowledge is essential for the development of standards and guidelines for the use of these materials. Naturally Occurring Radioactive Materials in Construction covers recent technical and regulatory developments concerning exposure to NORM. This book brought together experts from a wide range of countries to report on and discuss the progress made in identifying, quantifying and managing the radiological risks associated with industrial processes involving NORM. Chapters give a depiction on legislative issues, measurement, and assessment of building materials, physical and chemical aspects, from raw materials, to residues with enhanced concentrations of natural radionuclides (NORM), processes, building products containing NORM, and end-of-life and reuse requirements. The radionuclide activities of 226Ra, 232Th and 40K and radiological parameters (radium equivalent activity, gamma and alpha indices, the absorbed gamma dose rate and external and internal hazard indices) of building materials commonly used in construction have been studied in this book.This book serves as valuable guide for advanced graduate students, practitioners, researchers, and natural radionuclides processing establishments, as well as for those working in the building materials industry and construction sector, and policy makers.

Available in PDF, EPUB and Kindle. Book excerpt: From long-standing worries regarding the use of lead and asbestos to recent research into carcinogenic issues related to the use of plastics in construction, there is growing concern regarding the potential toxic effects of building materials on health. Toxicity of building materials provides an essential guide to this important problem and its solutions. Beginning with an overview of the material types and potential health hazards presented by building materials, the book goes on to consider key plastic materials. Materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds, are then explored in depth, before a review of wood preservatives and mineral fibre-based building materials. Issues related to the use of radioactive materials and materials that release toxic fumes during burning are the focus of subsequent chapters, followed by discussion of the range of heavy metals, materials prone to mould growth, and antimicrobials. Finally, Toxicity of building materials concludes by considering the potential hazards posed by waste based/recycled building materials, and the toxicity of nanoparticles. With its distinguished editors and international team of expert contributors, Toxicity of building materials is an invaluable tool for all civil engineers, materials researchers, scientists and educators working in the field of building materials. Provides an essential guide to the potential toxic effects of building materials on health Comprehensively examines materials responsible for formaldehyde and volatile organic compound emissions, as well as semi-volatile organic compounds Later chapters focus on issues surrounding the use of radioactive materials and materials that release toxic fumes during burning

Download or read book Evaluation of Guidelines for Exposures to Technologically Enhanced Naturally Occurring Radioactive Materials written by National Research Council and published by National Academies Press. This book was released on 1999-02-25 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Radiation Exposure and Occupational Risks written by Eberhard Scherer and published by Springer. This book was released on 2012-01-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Management of Naturally Occurring Radioactive Materials - known in the industry as NORM -has become an important part of the regular training required for workers in oil and gas production, refinery and petrochemical manufacturing, and in certain types of mining. Proper handling of NORM-contaminated wastes and use of appropriate radiation detection and protective equipment are now understood to be important components of good worker safety programs. Until now, no practical, easy-to-read, book was available to supplement worker training courses on NORM management. Naturally Occurring Radioactive Materials: Principles and Practices fills this void by providing, in a single publication, an ideal reference for industry managers, supervisors and line personnel. The book stresses the proper handling and management of NORM contaminated wastes and provides a firm understanding of the chemical properties of radioactive agents, their toxicological effects, and the appropriate containerization and disposal methods for these materials.
