THE FEATURES OF RADIONUCLIDES ACCUMULATION BY PYLAISIELLA MOSS IN THE ZONE OF LONG-TERM TECHNOGENIC PRESSURE, ON THE EXAMPLE OF PYLAISIA POLYANTHA
The accumulation features of radionuclides in the epitaphic pylaisiella moss (Pylaisia polyantha) in the territory of the city of Rostov-on-Don have been considered. The specific activities of 137Cs, 226Ra, 40K, and 232Th in the samples of moss, soils, and aerosol air have been compared. The capacity of Pylaisia polyantha to accumulate radionuclides has been estimated for four radionuclides (137Cs, 226Ra, 232Th, and 40K) with consideration for the background level. On the basis of radionuclide analysis, zones in the city of Rostov-on-Don with the highest accumulation coefficients of 137Cs, 226Ra, 40K, and 232Th were revealed. These were primarily the zones with both industrial and traffic loads and the motor transport zones
