Abstract

The paper considers the spread of tritium (3H) in the air basin and vegetation cover outside the former "Degelen" site. Data on the 3H content in the soil air and plants free water along the main streams (Uzynbulak, Karabulak, Baitles, Toktakushyk, Aktybay and Bezymyanny) with distance from the site boundary and away from the river beds are presented in the article. It is shown that 3H contaminated areas of the studied components are confined to zones of output and main streambed influence, which, in turn, are the main migration pathways for 3H beyond "Degelen".

Key words
Semipalatinsk Test Site (STS), radioecology, radioactive contamination, radionuclide, tritium (3H).
