Reconstruction of transuranium radionuclide radiation dose to the population in regions far from the Chernobyl accident
The objective of this study was to estimate the dose due to transuranic nuclides released during the Chernobyl accident. Calculations have shown that most of this dose was formed prior to May 6, 1986 and was due to curium 242 and the plutonium isotopes. With a 162.8 day half-life, the curium 242 fraction is presently negligible, while the americium 241 fraction is increasing. In this study, the total dose from curium 242 and plutonium isotopes was calculated for three specific population points far from the accident site. Calculations were performed for inhalation of the subject isotopes by an average adult male irradiated for 50 years, with analogous calculations performed for women and children. As most of the dose was received by inhalation, the calculations were sensitive to particle size, and the results obtained were expected to be an upperlimit. The effective whole-body dose was also calculated, as was the dose for certain organs. Based upon these calculations, the calculated risk factors for genetic and somatic consequences were low and consistent with observations since the accident.
