Abstract

The dynamics and present state of the radioactive contamination with 137Cs of littoral soil of Lake Kozhanovskoe and Lake Svyatoe on the Besed’ River are presented. The parameters of the vertical migration of 137Cs in soil-the rate of directional transfer with soil moisture, the diffusion coefficient, and the average velocity of vertical migration-are estimated by comparing the experimental and model distributions of 137Cs content over soil depth.

It is shown that at the present time the two 5-cm layer of soil can contain 20–90% 137Cs depending on the type of soil and landscape. The average values of the diffusion coefficient, the rate of directional transfer, and the vertical migration velocity for 12-, 13-, and 20-year periods after the Chernobyl accident are 0.1–2.8 cm2/yr, 0.1–0.3 cm/yr, and 0.1–0.8 cm/yr, respectively.
