Abstract

Analysis of uncertainties in reconstructed internal radiation dose was done. Uncertainties may be due to variation in a food diet of a specific person and the use of different models for dose estimating. In the absence of information on a person’s food ration uncertainty in individual radiation dose calculated with the use of radiometry data may be 200%-300%; at the same time, uncertainties in average radiation dose to residents of a specific settlement due to variation in a food diet of the population do not exceed 25-35%.

Key words
Radionuclides transport of iodine, radionuclides transport of caesium, food chains, radiation accident, uncertainties, internal doses, food ration, model of reconstruction.
