The (137)Cs accumulation by forest-derived products in the Gomel region.

This paper reports basic features of the (137)Cs uptake by forest-derived products in the Gomel region. Even with the soil contamination density of 37 kBq m(-2) the radionuclide contents in 20-30% of mushrooms and berries were found to be higher than the admissible levels. The (137)Cs contamination density of soil, site type and meteorological parameters were observed as the major factors which govern the radiocaesium uptake by mushrooms and berries.
