The physical-chemical forms of 137Cs and 90Sr occurence in soddy-podzol sandy-loam soil exposed to most severe radioactive pollution in Bryansk region, Russia, following the Chernobyl accident were studed. It was found that 137Cs was firmly fixed by mineral component of the soil, whereas the basic forms of 90Sr occurence were exchangable and acid dissoluble ones (40-90%).
