DOSES ASSESSMENT OF POPULATION AT LONG-TERM PERIOD AFTER THE CHERNOBYL ACCIDENT

Abstract

Republiccontaminated settlements had been developed. The results of the Whole Body measurements had been used as the basis for the model developing. The model for dose estimation is based on the classification of the settlements according to regional characteristics of soils, which cause 137Cs intake with locally produced foodstuff. The model is also based on regression of internal exposure dose on the soil surface activity for each region. The influence of the indirect factors on the dose forming had been taken into account: the number of inhabitants and the area of forest around the settlement. According to the developed method, Catalog of Average Annual Effective Doses for Residents of the Belarus Republic had been created.
