THE ALGORITHM OF RADIATION RISK GROUPS DISTRIBUTION OF POPULATION OF SOME TERRITORIES OF EAST KAZAKHSTAN REGION, AFFECTED BY RADIATION AFTER NUCLEAR WEAPON TEST AT SEMIPALATINSK NUCLEAR TEST SITE

The article deals with the distribution of radiation risk groups, formed by population of 6 rayons of East Kazakhstan region from 1949 to 1989, affected by radiation after nuclear weapon test at Semipalatinsk nuclear test site. Tempo-rary distribution of the main doze budget to decreed population of the studied rayons and average annual population trends are the main factors of formation of radiation risk groups, represented by people, personally affected by radia-tion of various doze budget and their descendants of the 2nd and 3rd generations. The authors take into account popu-lation trends of the studied rayons, which determine the abovementioned distribution of radiation risk groups. The results of the study allow forming research groups for the assessment of radiation influence in the various periods and determine the needs of the specialized medical aid for the affected communities.
