Infiltration and radionuclide migration in the Bryansk region

摘要

The study is a part of the Project RUS/95/004 of the UN Program of Development in the Russian Federation (UNDP), evaluating and predicting the water quality within Bryansk region (Russia), which was affected by the Chernobyl accident. The radioisotope tritium was used as a tracer to determine seepage velocities and specific recharges through the aeration zone, as well as dispersion and retardation parameters for different landscapes and lithological unites in the Bryansk area. The obtained data were used to approach an assessment of "Chernobyl" ~(137)Cs-radionuclide migration.
