Abstract:The studies of 137Cs and 90Sr accumulation characteristics by birch wood (Betula pendula Roth.) growing in different edaphic conditions. Describes the increase in soil fertility from trophotops A to D results in 5-fold 137Cs transfer factor decrease and 2-fold decrease of 90Sr. Soil humidity increase for each grade of trophic net results in the increase of 137Cs transfer factors to wood and decrease for 90Sr. Total activity of 137Cs and 90Sr in birch wood plantation depends on productivity of plantation and on radionuclide transfer factors depending on different plantation conditions. In the most prevailing edaphotops (B2, ВЗ, С2 and C3) birch wood accumulates 0.6-1.2% of 137Cs and 13-19% of 90Sr from total activity of radionuclides in biogeocenosis.
