Main dependencies in reduction of radiation exposure to the population of the Southern Urals. | LitMetric

AI Article Synopsis

Article Abstract

Dynamics of soil contamination, food chain, and radiation doses to population at the East-Urals Radioactive Trace (EURT) and the Karachay Radioactive Trace (KRT) are reviewed. Gamma spectrometric analysis of samples was performed according to standard methodology; 90Sr was determined by the extraction method. Over 80% of radionuclides in soil are contained in the upper 20-cm layer. Biologically available forms of Sr and insoluble forms of 137Cs are predominant. The main reasons for reduction in milk contamination are radioactive decay and sequestration of radionuclides in soil. Current annual intake of radionuclides with food: EURT--310 Bq (90Sr), KRT--324 Bq (90Sr) and 732 Bq (137Cs).
