Artificial and Natural Radionuclides in Soils of the Southern and Middle Taiga Zones of Komi Republic

摘要

Specific activities of artificial (Cs-137, Sr-90) and natural ((40)De, Th-232, Ra-226) radionuclides in background soils of southern and middle taiga of Komi Republic have been estimated with consideration for the landscape-geochemical features of the territory. It has been shown that their accumulation and migration in soils are determined by the following factors: position in relief, texture, and organic matter content. No anomalous zones with increased contents of radionuclides in soils have been revealed.
