DOWNLOAD EBOOKThis handbook has been produced in collaboration with the International Union of Radioecologists. It should serve as a convenient and authoritative reference for radionuclide transfer parameter values used in biospheric assessment models. It supplements Safety Series No. 57 (1982), Generic Models and Parameters for Assessing the Environmental Transfer of Radio- nuclides from Routine Releases.

DOWNLOAD EBOOKThis handbook provides generic parameter values for estimating the transfer of radionuclides from environmental media to wildlife for the purpose of assessing potential radiation exposure under equilibrium conditions. These data are intended for use where site specific data are either not available or not required, and to parameterize generic assessment models. They are based on a comprehensive review of the available literature, including many Russian language publications that have not previously been available in English. The publication addresses the limitations of the parameter values and the applicability of data. Some general background information on the assessment of potential impacts of radioactive releases on wildlife is also included. It complements the existing handbook in the same IAEA series with parameter to assess the radiological impact to humans.

DOWNLOAD EBOOKThis 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.

DOWNLOAD EBOOKNaturally 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 EBOOKThe marine environment, in addition to a not insignificant background of "natural" radioactivity, has continued to receive inputs of radionuclides directly or indirectly through atomic fallout, discharges from the nuclear industry or from nuclear accidents. After their introduction, the fate of these radionuclides is complex with modifications of physicochemical forms, dispersion in marine water masses and adsorption onto sedimentary particles. Marine organisms then bioaccumulate these radionuclides to a greater or lesser extent, dispersing them via their burrowing activities, horizontal and vertical migrations or through food webs. All of these phenomena lead to very variable radioactive contamination, depending on location and the nature of the marine environments concerned, and consequently, to very different doses of irradiation to marine organisms. The harmful effects of ionizing radiation on living marine organisms are felt at varying levels of biological organization from the molecule to the ecosystem, passing through the cell, the organ, the individual and the population. In the end, the radioactive risk for marine organisms can decline according to several situations, which can be normal, programmed or accidental.
