Book Description
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.

Book Description
This publication is one of the series of IAEA publications on the environmental behaviour of naturally occurring radionuclides. It outlines uranium behaviour in different environments, as well as its transfer to, and metabolism in, humans. The publication also provides concepts, models and data required for the assessment of the impacts of uranium on non-human biota. Assessing the environmental and health effects of uranium poses specific challenges because of the combination of different types of hazard and potential exposures. Therefore, both the radiotoxicity and chemical toxicity of uranium are considered in this publication.

Book Description
This introductory manual addresses environmental site restoration practices that both ensure compliance with federal statutes and prevent further contamination or expense. Emphasizing environmental chemistry, soil science, microbiology, plant science, and the underlying chemical processes, Fundamentals of Site Remediation incorporates relevant chemical principles into the cleanup and removal of hazardous chemicals from soil, geological strata, and groundwater.

Book Description
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.

Book Description
Mme. Curie discovered polonium as a part of her doctoral thesis research. Polonium was the first element to be discovered solely because of its inherent radioactivity. Because there was no knowledge of polonium's chemical properties, the separation steps were followed using only the increase in the specific radioactivity. The first Gmelin Polonium volume, edited in 1941, shows how little was known about polonium for a long time. More detailed investigations on this element were performed only after World War II when the handling of large quantities of highly radioactive nuclides had been developed. Most information on this heaviest Main Group VI element comes from investigations on the tracer scale, especially data that describe its behavior in solution. On the other hand, many solid compounds, such as halides, oxides, and metal polonides as well as the metal itself, are produced in weighable amounts so that structural data are also available. However, these data are far from complete so there is a wide-open field for future research, especially by using the newly developed ultramicrotechniques for preparation and identification of radioactive compounds in the nano- to microgram range. The present volume of the Gmelin Handbook, Polonium Suppl. Vol. 1, gives a very clear, critical, and updated picture of the different aspects of the behavior of polonium - from chemical and physical properties to production, from the nuclear properties of the 29 isotopes to its biological and environmental behavior, and finally to the use of polonium in a variety of applications. Because of the interest in this element has decreased markedly in recent years (apart from its environmental behavior), this volume will be a special and unique source for polonium information for a long time. It also clearly shows that large gaps in our knowledge of this rare natural radioelement still exist. Consequently the volume can serve as a guide to future research initiatives.

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.
