DOI: 10.1007/s10967-010-0908-7
Keywords: Soil to mushroom transfer, 137Cs, 40K, Alkali–alkaline earth elements, Heavy metals
Abstract: The present work is devoted to an investigation on the soil to mushroom transfer parameters for 137Cs and 40K radionuclides, as well as for some stable elements and heavy metals. The results of transfer factors for 137Cs and 40K were within the range of 0.06–3.15 and 0.67–5.68, respectively and the most efficiently transferred radionuclide was 40K. The TF values for 137Cs typically conformed to a lognormal distribution, while for 40K showed normal distribution. Statistically significant correlations between 137Cs soil to mushroom transfer factors and agrochemical soil properties have been revealed. Although the concentration ratios varied within the species, the most efficiently transferred elements seems to have been K, followed by Rb, Zn, Cu, Cd, S, Cs and Hg.

Title: A tale of two forests: addressing postnuclear radiation at Chernobyl and Fukushima
Author: Winifred A. Bird and Jane Braxton Little
Reference: Environ Health Perspect. 2013 March; 121(3): a78–a85.
DOI: 10.1289/ehp.121-a78
Keywords: forest, Fukushima, Chernobyl
Abstract: To report this story, Jane Braxton Little traveled to Chernobyl, and Winifred A. Bird made numerous trips to the Fukushima area. For Little, whose Harvard MA is in Japanese cultural history, it was the Fukushima accident that sparked her interest in how radiation affects ecosystems and led to her first visit to Ukraine. Bird has been living in Japan and writing about natural resource issues since 2005; in July 2011 she reported for EHP on chemical contamination following the Tohoku tsunami and earthquake. Seeing the effects of the accidents firsthand and interviewing residents and cleanup workers on the ground deepened the partners’ understanding of the management issues and the underlying science.

Title: Retrospective evaluation of irradiation doses of the population in the territories contaminated by the radionuclides from the Chernobyl accident
Author: Sokolov, Victor Vasiliyevich
Reference: Tula, 2002
Keywords: geosystems, landscapes, population , forest, radionuclides
Abstract: The aim of this work was to establish a new and refinement of existing patterns of formation of dose-forming fields and retrospective assessment of radiation exposure during external and internal exposure of the population living in areas contaminated by Chernobyl fallout radionuclides in the landscape-geochemical conditions in the central regions of Russia, for effective environmental monitoring and assessment non- epidemiological morbidity of the population .

Title: Decision making framework for application of forest countermeasures in the long term after the Chernobyl accident

DOI: http://dx.doi.org/10.1016/j.jenvrad.2004.10.014
Keywords: Chernobyl accident; Forest countermeasures; 137Cs; Decision making
Abstract: After the ChNPP accident a very large part of the territories covered by natural and artificial forests are contaminated with long-lived radionuclides, especially 137Cs. To protect people against exposure associated with forest contamination in the most affected regions of the NIS countries, countermeasures have been developed and recommended for the forest management. The paper presents a decision making framework to optimise forest countermeasures in the long term after the ChNPP accident. The approach presented is based on the analysis of the main exposure pathways and application of radiological, socio-economical and ecological criteria for the selection of optimal countermeasures strategies. Because of the diversity of these criteria modern decision support technologies based on multi-attributive analysis were applied. The results of the application of this approach are presented in a selected study area (Novozybkov district, Bryansk region, Russian Federation). The results prove and emphasize the need for a flexible technique to provide the optimised forest countermeasures taking into account radioecological, social and economic features of contaminated forests.

Abstract: Reviews scientific principles of specified radiological division (zoning) of forests contaminated by radionuclides due to the Chernobyl accident. Presents detailed ecological and silvicultural characteristics of radio-ecological regions. Suggests general classification of forest ecosystems on different groups of radioecological stability, based on the duration of rehabilitation of social and economic values and resource potentials of the forests after the radiation exposure.

Keywords: forest radioecology, 90sr, vegetation, soil
Abstract:The algorithm of display of 90Sr’s behavior mechanism in forest ecosystems by method of imitating modeling is developed. Distinctive features of algorithm: the 90Sr contents in vegetation is subdivided into two parts (outside and internal pollution), whose dynamics is considered separately; dynamics of radionuclide is considered in connection with dynamics of organic substance; it is supposed, that 90Sr’s behavior in plants is similar to Ca behavior; the biological availability 90Sr contained in a soil, is integrated function of time and physico-chemical properties of the given soil. On the basis of offered algorithm the model is constructed which is used for realization of a number of numerical experiments, including reconstruction of a situation of pollution of forest ecosystem on grey forest soils in result of Kyshtym accident. The quantitative estimations of intensity of 90Sr redistribution between stand components and soil are received. The modern problems of creation of prognostication models of 90Sr dynamics in the forest ecosystems are discussed.
