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.
