The objective of this work was to study the factors affecting the intake of Sr-90 and Cs-137 by plants from soils exposed to radioactive contamination resulting from operations of the Mayak Industrial Association. Specific activities of Sr-90 and Cs-137 in the samples were determined by the radiochemical method. The most severe contamination by Sr-90 and Cs-137 of natural soils was found in forest soil cover and in the 0-5 cm soil layer. The contamination density of the area is mainly determined by activity in the soil layer 0-20 cm that contains 3-97% of Sr-90 and 60-92% of Cs-137. Portions of radionuclides contained in soil (89-96% of Sr-90 and 18-73% of Cs-137) can be converted into cationic use. An insignificant share of water-soluble radionuclides goes from soil to agricultural produce. Health Phys. 103(1):56-57; 2012
