This paper estimates the body content and excretion levels of Pu from the combined intake from the global and Chernobyl fallout. The approach developed allows to estimate the contributions from each component. This approach is necessary for estimating the average and collective doses to the population of different regions or settlements. Verifications of this approach have been made using autopsy data (the early stage of the accident, Kiev residents, the late stage inhabitants of the Ovruch region) which are in good agreement. Assessment of the dose from transuranics to the population of the Ukraine required using bioassay data. This was achieved by measuring the urinary excretion of Pu.
