RURAL SETTLEMENTS: SOCIAL AND ECOLOGICAL FACTORS OF DOSE FORMATION

Abstract

The aim of the study is to reveal that average internal dose in a settlement is the function of its environmental factors and social constitution. The method of investigation - statistic analysis of the internal dose in rural residents depending on number of factors: radioecological, marked in conversion factor of radionuclides from soil into milk; environmental - close location of a settlement to forest; social - number of population and demographic structure. Comparison of mean dose of internal irradiation was conducted in 10-years dynamics in rural residents of Vetka and Hoiniki districts situated in territory with approximately equal contamination density who had been earlier grouped by this feature. The internal dose depends not only on the degree of radio contamination of the territory but on the number of other factors such as: environmental - close to forest which in its turn determines access to forests «products», and social - number of population, social - age structure. None of these factors determine dose formation. Their influence on the process of dose formation in settlements must be regarded in the aggregate.
