THE MONITORING OF INTERNAL EXPOSURE DOSES IN POPULATIONS IN THE REMOTE PERIOD AFTER THE ACCIDENT AT THE CHERNOBYL NUCLEAR POWER PLANT

Abstract

One of the tasks of dose monitoring in the long-term period after the Chernobyl accident is proper estimation of exposure dose in the population of settlement that are located in the territory of radioactive contamination. The proper estimation of internal exposure dose is possible due to conducting dedicated and regular whole-body counting of population of those settlements that are the most typical in relation to the terms of internal exposure dose forming. These settlements serve as control points for the monitoring system of internal exposure doses. The results, which were obtained during the examination of control settlements, can be used for periodic inspection for conformance of settlement zoning to the actual radiation conditions and population dose obtained from radiation fallout after the Chernobyl accident; also, it can be used for current predictive pattern estimation. The conducting of whole-body counting in the control settlements makes it possible to transform general dose monitoring into dedicated. That optimizes materials costs without quality loss of the radiation exposure estimation in the population.
