Available in PDF, EPUB and Kindle. Book excerpt: Food-chain transport of Pb-210 and Po-210 from soil to edible plant parts and from animal feed to meat and milk were evaluated from a review of literature. The degree of transfer was characterized by estimating concentration factors (unweighted arithmetic means) as well as the transfer coefficients B/sub v/, B /sub r/ (unweighted geometric means, f/sub m/ and f/sub f/ (unweighted arithmetic means). Global dietary intake of Pb-210 and Po-210 was also summarized, and 50-year dose estimates to target organs calculated. The greatest estimated ingestion doses were those to populations with large dietary complements of animal protein in the form of seafood (Japan) or caribou/reindeer muscle and organ meats (Arctic Eskimos and Lapps). The magnitude of this latter source illustrates the importance of simple food chains in generating significant exposures to populations dependent upon them. The origin and magnitude of inhalation exposure and dose from tobacco products was also assessed. For the majority of internal organs evaluated, the dose resulting from smoking commercially available tobacco products is comparable to or greater than the dose estimates for ingestion of naturally occurring dietary Pb-210 and Po-210.

Available in PDF, EPUB and Kindle. Book excerpt: Polonium-210 is an alpha emitting radionuclide with no radioactive progeny and produces only very-low-intensity gamma rays at very low abundance. This means doses largely arise from internal exposure. In addition to the relatively high ingestion does coefficient of 210Po, radionuclide transfer in the environment results in high activity concentrations in certain foods. This publication focuses on radionuclide transfers in terrestrial, freshwater and marine environments, and provides information on key transfer processes, concepts and models--back cover.

Download or read book Organic Scintillators and Scintillation Counting written by Donald Horrocks and published by Elsevier. This book was released on 2012-12-02 with total page 1095 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic Scintillation and Liquid Scintillation Counting covers the proceeding of The International Conference on Organic Scintillators and Liquid Scintillation Counting, which was held on July 7-10, 1970 at the University of California, San Francisco. This conference was held to discuss ideas concerned with the theory and physics of organic scintillators and the use of liquid scintillation for radioactivity measurement and other analytical applications. This text discusses liquid scintillator solvents, the vacuum ultraviolet excited luminescence of organic systems, and the application of scintillation counters to the assay of bioluminescence. Also covered are topics such as scintillation decay and absolute efficiencies in organic liquid scintillators, dose rate saturation in plastic scintillators, and the mass measurements in a liquid scintillation spectrometer. The book is recommended for physicists who would like to know more about the advancements in the field of organic and liquid scintillation and its applications.

This book was released on 1988-02-01 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes hazards from radon progeny and other alpha-emitters that humans may inhale or ingest from their environment. In their analysis, the authors summarize in one document clinical and epidemiological evidence, the results of animal studies, research on alpha-particle damage at the cellular level, metabolic pathways for internal alpha-emitters, dosimetry and microdosimetry of radionuclides deposited in specific tissues, and the chemical toxicity of some low-specific-activity alpha-emitters. Techniques for estimating the risks to humans posed by radon and other internally deposited alpha-emitters are offered, along with a discussion of formulas, models, methods, and the level of uncertainty inherent in the risk estimates.
