Abstract: The investigation of accumulation levels of 137Cs in biomass of main field crop rotation cultures (wheat, barley, potato) and of meadow ecosystems in -Plavsk radioactive spot of Tula region demonstrated that at density of radioactive pollution of soils ~200-430 кBq/m2(5-12 Ki/km2) green parts of plants accumulate 0,01-0,02 кBq/m2, and underground parts œ 0,1-3,3 кBq/m2. Accumulation 137Cs in biomass depends on biological features of vegetation, and also is in close direct dependence with accumulation of 137Cs in soils.
