title: [The assessment of the content of 137Cs of the global and Chernobyl origin in forest soils and some types of edible fungi].
abstract: The article analyzes the density of pollution of the soil by radioisotopes of caesium and the content of 137Cs in fruit bodies of some species of forest mushrooms on the "long" trail of radioactive fallout in the Republic of Belarus in 1994 and 2012. On the basis of the calculated density of pollution of the soil with 134Cs in 1986 the contribution to the total density of pollution with 137Cs of the global radioactive fallout and emissions owing to the accident at the Chernobyl nuclear power plant was defined for the studied territory. It was established that at the density of pollution of the soil by 137Cs of 12-19 kBq/m2 in 1986 about 35% of pollution was caused by the global radioactive fallout. In 1994 and 2012, a specific activity and transfer factor of 137Cs were analyzed for fruit bodies of some species of forest mushrooms. The transfer factors of 137Cs for fruit bodies of Boletus edulis are at level of 10 x 10(-3) m2/kg, Leccinum scabrum and Leccinum aurantiacum - (15-20) x 10(-3) m2/kg, Xerocomus badius--(60-80) x 10(-3) m2/kg.
