To assess the levels of radioactivity, the soils of the Arctic region of Western Siberia were studied. The content of Cs-137 in the soils of the studied region ranges from 2 to 9 Bq/kg, with an average value of 4 Bq/kg.
The average contents of natural radionuclides (U, Th and K-40) in soils are determined by the radioactivity of the parent rocks. The radioanalytical results showed that the average Th content is 2.8 (0.3-6.7) ppm; U – 2.0 (0.5-6.6) ppm, K-40 – 233 (16-473) Bq/kg in the soils.
This work was supported by the Russian Science Foundation grant (project No 18-77-10039). Analytical studies were carried out at the Center for multi-elemental and isotope research SB RAS.
