[Dosage of irradiation of the population in the Bryansk region with plutonium deposited in the soil after the Chernobyl AES accident].
Proceeding from the data on 238Pu, 239Pu, 240Pu concentrations in the soil in different areas of the Bryansk Region, exposed to radioactive contamination after the Chernobyl accident, radiation dose exposures of residents as well as agricultural workers were assessed. Criteria of the ecological and radiation-hygienic standardization were used for calculation of values of dose factors, binding the alimentary and inhalation components of an irradiation dose with characteristics of Pu deposition in the soil. Inhalation of soil particles accounted for approximately 90% of a total radiation dose of the "soil" Pu component, and the alimentary component-for approximately 10% (of this, 99% were attributed to plant products). The authors proposed prognostic assessment of an expected effective equivalent dose for a period of 70 years for people, residing in these areas (0.08-0.45 cSi for the population and 0.6-3.2 cSi for mechanics).
