[Estimation of soil fraction of Pu in the formation of irradiation dose of inhabitants of the Bryansk region]. / Znachimost' "pochvennoi fraktsii" Pu v formirovanii doz oblucheniia naseleniia Brianskoi oblasti.

The estimation of plutonium in soils of the contaminated after Chernobyl accident areas of Bryansk Region (Russia) are presented. On the basis of data about Pu concentrations in soils and by means of migration models in "soil-man" system the doses received were assessed. Pu-239, 240 and Pu-238 were determined in samples of autopsy material (lung, liver, bones and tracheobronchial lymph nodes) of residents from Chernobyl-fallout contaminated regions. Effective doses have been obtained by means of data about Pu-concentration in autopsy samples.
