THE CONTENT OF RADIONUCLIDES IN MUSHROOMS IN THE IMPACT ZONE OF SEMIPALATINSK TEST SITE

https://doi.org/10.52676/1729-7885-2020-2-87-92

Abstract

The article provides research findings of levels and parameters of naturally occurring (40K, 226Ra, 232Th) and artificial (241Am, 137Cs, 90Sr, 239+240Pu) radionuclides accumulation by mushrooms in the territory adjacent to Semipalatinsk Test Site (STS), in the zone of fallout plume passing after the first nuclear test (August 29, 1949). It was found that, as a whole, none of activity concentration values, resulted for radionuclides in mushrooms, exceeds the permissible level. The main contribution to the total dose of internal exposure through ingestion of radionuclides, when mushrooms are consumed in the territory of interest, is made by the dose from naturally occurring radionuclides.
