- Аннотация: In the remote period after the radioactive fallout in the Chernobyl accident, the biological cycle of 137Cs in pine forests of the northern forest-steppe zone and in those of Bryanskoe Polesye become essentially different. In the cleaner northern zone with dark-gray forest soil, the 137Cs flux to the soil with litterfall exceeds its influx to the vegetation by a factor of 5; i.e., the 137Cs cycle differs from that of stable K, the descending flux being still dominant. In the more contaminated Bryanskoe Polesye zone with podzolic illuvial-iron sandy soil, the annual 137Cs influx to above-ground vegetation via root uptake exceeds its return to the soil with litterfall, i.e., the 137Cs cycle approaches the biological cycle of stable K.
