Intakes of Radionuclides : Occupational and Public Exposure. Workshop. Avignon, FRA, 1997/09/15.
The aim of the present research is to study the possibility of monitoring internal radiation doses to the population of the heavily contaminated zone at the late stage of the Chernobyl accident.
Two methods of calculation of body content for a particular radionuclide are suggested.
They are based on the data on amounts of specific radionuclides in fallout and their levels in daily urine samples of the inhabitants.
The results obtained show that almost 25% of internal radiation dose to the inhabitants of the village of Otashev is contributed by intakes of 90Sr.
The contribution of transuranium elements to the total dose is estimated to be about 1.5%. It is generally concluded that monitoring of the internal radiation dose of the inhabitants of the heavily contaminated zone at the late stage of the accident is not only possible, but is also of considerable scientific and practical interest.
