The dynamics of mortality of the population of the Altai territory exposed to radiation

The territory of the Altai Krai was repeatedly exposed to radiation as a result of nuclear tests in the Semipalatinsk test site. Altai medical dosimetric registry was created as a regional segment of the National radiation-epidemiological registry to provide complex analysis of the harm to the health of the population having been located in the areas exposed to radiation as a result of nuclear tests in the Semipalatinsk test site (NRER) [4]. Currently, the contents of the regional segment of NRER have been expanded and now include the citizens having been exposed to radiation as a result of nuclear tests in the Semipalatinsk test site, the accident at the Chernobyl APP, and the accident at the Industrial Association Mayak [5]. The objective of the study is to obtain up-to-date data on the health of the contingents of the regional segment of NRER. The present research shows the results of the study of the peculiarities of the contents and mortality of the contingents of the regional segment of NRER. The most numerous registration categories were discovered and their mortality in 2015-2016 was analyzed. The most numerous contingents in the regional segment are people exposed to radiation as a result of nuclear tests in the Semipalatinsk test site. The most significant causes of death among the contingents under study were revealed. The highest death rates were noted among the subjects with radiation sickness induced by the radiation impact caused by the Chernobyl accident, as well as among Chernobyl disaster liquidators of 1986-1987. The data on general mortality were obtained, as well as on the main causes of death among the most numerous contingents; these data were also compared to the death rate of the population of the Altai Territory. The results of the research are going to be used to work out measures aimed at health optimization of the people registered with the regional segment of NRER.
