Estimation methodology of pollution levels of agricultural territories by gas-airsoles emissions from nuclear fuel cycle enterprises

Korzhavin A.V., Trapeznikov A.V., Trapeznikova V. N.

Summary

Open territories of agricultural grounds first of all are the subject of influence of gas-aerosol emissions from nuclear fuel cycle enterprises. Influence of gas-aerosol emissions from the "MAYAK" Enterprise in Chelyabinskaya area on agricultural territories in a southern part of Sverdlovskaya area by the level of the maintenance of long-living radionuclides in the environments which play a role of natural tablets (snow cover, water of open reservoirs, top layers of soils) is studied. It is shown, that current atmospheric 137Cs and 90Sr losses in 2006-2010 in the surveyed territory corresponded to level of global losses. 239,240Pu pollution density of snow cover in different years differed by order, but in a quantitative sense the 239,240Pu maintenance in snow cover corresponds ~10-2 10-3 Bq counting on square meter, that cannot render essential influence on radiating conditions of agricultural territories in Sverdlovskaya area.

Key words: agricultural territories, gas-aerosol emissions, long-living radionuclides, pollution density.
