Estimation of radioactivity in fungal fruit bodies of the genus Leccinum fungi collected in the area of Hibiny Mountains
Author: Ivanov D.M., Efremova M.A.
Reference: Bulletin of St. Petersbourg University: Biology, 2012
ISSN: 1025-8604
DOI: 582.287.23:574
Keywords: BIRCH MUSHROOMS, ASPEN MUSHROOMS, HIBINY, ARTIFI CIAL AND NATURAL RADIOISOTOPES, ACCUMULATION FACTOR, 137cs, 40k
Abstract: The article reveals that concentration of 137Cs and other radioisotopes in the fungal fruit bodies of the Leccinum genus collected in the area of Hibiny Mountains is within the limits of the admissible values. The accumulation factors of 137Cs and 40К in the fungal fruit bodies depend on soil acidity. Changes in soil рНН2О from 5,40 up to 7,33 cause a decrease of the accumulation factors of radioisotopes in fungi by more than 7 times.

Keywords: 137cs, 90sr, river, lake
Abstract: The dynamics of the radioactive contamination with 137Cs and 90Sr of the Besed’ and Iput’ rivers in 1987–2004 and the nondraining Lake Svyatoe on the Besed’ River and the slowly draining Lake Kozhanovskoe in 1992–2002 is prsented. Data on the contamination of the components and shorelines of reservoirs are presented. It is shown that the radioactive contamination of these rivers is decreasing; the present level of contamination is much lower than the intervention level. The radionuclide content in the nondraining and slowly draining lakes remains high. Specifically, the 137Cs concentration in the waters of Lake Svyatoe on the Besed’ River is at the intervention level, and the 137Cs concentration in the fish in Lake Kozhanovskoe is ten times higher than the established norms.

ACCUMULATION OF CAESIUM-137 IN NATURAL AND AGRICULTURAL GRASS ECOSYSTEMS ON RADIOACTIVE CONTAMINATED TERRITORY OF TULA REGION

ISSN: 2221-951x
DOI: 57.045:57.042
Keywords: 137cs, agricultural products, accumulation, soil
Abstract: The investigation of accumulation levels of 137Cs in biomass of main field crop rotation cultures (wheat, barley, potato) and of meadow ecosystems in -Plavsk radioactive spot of Tula region demonstrated that at density of radioactive pollution of soils ~200-430 кBq/m2(5-12 Ki/km2) green parts of plants accumulate 0,01-0,02 кBq/m2, and underground parts œ 0,1-3,3 кBq/m2. Accumulation 137Cs in biomass depends on biological features of vegetation, and also is in close direct dependence with accumulation of 137Cs in soils.

Keywords: natural and technogenic radionuclides, 40k, 232th, 226ra, 137cs, Tula region
Abstract: The modern radiating background of the Plavsky radioactive spot of Tula region is formed at the expense of natural (40К,232Th,226Ra) and technogenic radionuclides (137Cs). Thus the share 137Cs from the general stocks of radionuclides in soils makes 48-67 %, and as a part of vegetative production œ only 5-14 % that reveals insignificant parameters of transition of an element from soils in plants.
DYNAMICS OF DECREASING CAESIUM 137 IN AGROCENOSES OF AUTUMN WHEAT IN ORYOL REGION FROM 1985 TO 2007

Abstract: The purpose and objectives of research. The aim of this study was to identify and analyze the basic laws of biologically significant behavior of radionuclides release in Chernobyl NPP (137Cs, 90Sr and 239’240Pu) into soils of Ukraine affected by radioactive contamination, assessment of the specific features significance of the post-accident situation (heterogeneity of soil’s surface and the characteristics of territory’s radioactive contamination, multiplicity of radioactive fallout forms, marked mottling of radioactive contamination of the territory) the intensity of radionuclides’ inclusion in biogeochemical chain migration and specificity of radiation exposure doses formation, long-term prognosis of radionuclides redistribution, released into the components of soil and vegetation layer/surface.
