After 36 years the disaster at the Chernobyl nuclear power plant, 60‒80 % of radiocesium is contained in the soil layer of 0‒10 cm, and 3‒30 % is in the soil layer of
10‒20 cm. The maximum content of radiocesium in the soil layer 0‒10 cm is 4520 Bq/kg, the minimum is 495 Bq/kg. These parameters in the soil layer of 10‒20 cm are 1040 Bq/kg and 44 Bq/kg, respectively. The highest specific activity was noted in the tufted vetch (2196±439 Bq/kg) and the lowest in the columbine cornweed (96±66 Bq/kg). The accumulation coefficient varied over a wide range 0.05–2.55 Bq/kg: Bq/kg.
