Abstract: The assessment of 137Cs concentration in water based on the model of radionuclide absorption by the bottom sediment of a closed water body is applicable to deep-water lakes with slower water circulation (the time of water exchange exceeding 10 years). The low river runoff from such lakes does not determine their water purification from 137Cs because of the predominance of the process of 137Cs sorption by suspension and bottom sediment. The contamination of a deep-water arctic lake with global 137Cs is reconstructed.
