Abstract

This paper presents the results of radioactivity studies of environmental factors such as surface water, sediment, aquatic vegetation and soil. The concentrations of137Cs,90Sr,3H, U, Ca, and Mg in water samples were determined by radiochemical and chemical methods. Gamma-spectrometric analyses were performed for all the samples. The analysis showed a decrease in concentrations of137Cs in water, aquatic vegetation and sediment, but a constant level of137Cs activity in soil (0–5 cm depth). The average concentrations of90Sr,3H, U, Ca and Mg were about 7 mBq/l, 11 Bq/l, 0.6 μg/l 60 mg/l and 11 mg/l, respectively.
