Abstract

The paper provides results of investigation of features of radionuclides redistribution in water-soil system and in ecosystems associated with radioactively contaminated waterflows from tunnels at the “Degelen” site of the Semipalatinsk test site. Calculated ratios of specific activity of 137Cs, 90Sr, 239+240Pu and 241Am in water and soil demonstrate disbalance in the system. Though the radionuclides present in the waterflows are permanently carried out to the surface terrestrial and aquatic ecosystems no extremely high concentration of the radionuclides in the environment is registered.

Key words
The Semipalatinsk test site (STS), radionuclides, cesium-137 (137Cs), strontium-90 (90Sr), plutonium-239+240 (239+240Pu), americium-241 (241Am).
