ABSORBED RADIATION-DOSE IN PLANTS OF NATU RAL COMPLEXES IN BYELARUS OVER THE PAST 10-YEAR FOLLOWING THE CHERNOBYL ACCIDENT

An absorbed radiation dose in plants of the natural complexes in Belar us for 10 years following the Chernobyl accident was calculated. The d ata on dynamics of exposure dose rate in the area for 10 years were us ed for calculating the absorbed dose due to external irradiation and t he data on the specific activity of the plants due to incorporation of caesium-137 and strontium-90 were taken into consideration when calcu lating the absorbed dose due to internal irradiation. The highest cont ribution to formation of absorbed doses of ionizing radiation in plant s in the radiocontaminated zones belongs to internal irradiation of pl ant organisms due to incorporated radionuclides, in particular caesium -137.
