IN SITU MEASUREMENTS OF DENSITY OF ~(137)Cs CONTAMINATION OF THE FOREST SYSTEM IN UKRAINE

摘要

The Chernobyl accident resulted in significant contamination of Ukrainian ter- ritory by various radionuclides. The activity of the main dose forming radionuclide released into the environment, ~(137)Cs, was estimated to be approximately 3.1 × 10~(16) Bq. The density of surface contamination of different natural systems by ~(137)Cs is the characteristic used for assessment and prediction of the radioecologi cal situation.
