Abstract


The results of the exploration of 137Cs distribution in peatbogs soils of mezoolihotrophical marshes are presented. For substantiation of determined regularities following indexes were used: specific and summary (gross) activity of radionuclide in the layer of tow and peat. It is demonstrated that both indexes have the biggest value in the layer of tow – depth 15-20 cm. It is determined that the tow contains 62.2 % of summary activity of 137C in soils. The conclusion is drawn as for considerable deepening of radionuclide in the soil and gradually extraction from the root-inhabited layer that can bring in time to decreasing of tempos of radionuclide incoming into plants.
