АККУМУЛЯЦИЯ 137Cs ЛИШАЙНИКОМ HYPOGYMNIA PHYSODES (НА ПРИМЕРЕ ГОМЕЛЬСКОЙ ОБЛАСТИ)

The paper presents the results of determining 137Cs content in biomass lichen Hypogymnia physodes, which growing pine forests on territory Gomel region with various levels radioactive contamination.The research was carried out both conditionally clean and radioactively contaminated areas soil contamination density from 37 to 1488 kBq m-2. high accumulating capacity physodes relation shown, as well an increase concentration radionuclide lichens contamination. Differences accumulation by uneven-aged stands, were noted. lowest concentrations noted samples mature forests, while thalli sampled young stands contain significant amounts radionuclide.
