Popis: The assessment of caesium-137 accumulation in parts of fungi fruiting bodies of Leccinum aurantiacum (Bull.) Gray in a mixed spruce-aspen forest on sod-podzolic soil was carried out. Average specific activity of cesium-137 for caps is 1814±112 Bq/kg and for stems 873±73 Bq/kg. It was found that the specific activity of cesium-137 does not exceed the permissible values, but significantly differs between the cap and stem of fruit bodies. The coefficients of cesium-137 accumulation from soil vary for caps from 4.6 to 6.1 and for stems from 1.7 to 2.8. High specific activity of cesium-137 in aspen leaf fall 289±27 Bq/kg and litter 339±23 Bq/kg compared to the underlying soil horizons was noted.
