Abstract: Results of long-term studies of ¹³⁷Cs accumulation in the Frangula alnus Mill. bark in wet subory in forests of Ukrainian Polissia are presented. The reduction of specific activity of the radionuclide in the bark of this plant and the dependence of the indicator on the density of soil radioactive contamination is shown. The redistribution of ¹³⁷Cs in sod-middle-podzolic soils of Ukrainian Polissia forests in wet subory eventually is shown. It is determined that the main amount of ¹³⁷Cs is currently located in the upper layers of the mineral part of the forest soil. The lower decomposed layer of the forest litter has the highest ¹³⁷Cs specific activity, but due to its low density, it has the low content of the radionuclide (11.7 ± 1.3 %).

Keywords: radionuclides, medicinal plants, frangula alnus bark, soil contamination, specific activity of the radionuclide, sod-podzolic soils.
