Assessment of formation of the dose of internal irradiation of population at the remote stage of overcoming of aftereffects of Chernobyl disaster

Abstract

Goal. To elucidate the peculiarities and nature of the formation of the dose of internal exposure of the population at the remote stage of overcoming the consequences of the Chernobyl accident. Methods. The research was carried out in settlements of Kyiv, Zhytomyr and Chernihiv regions with the help of a human radiation meter. An array of data is considered as a statistical collection of random variables, the type of distribution and a number of statistical indicators are determined. Results It has been found that now some aggregates show signs of not only lognormal but also exponential and normal laws. This indicates the stabilization of conditions affecting the formation of magnitude, and the absence of prevailing reasons (their balancing) of the formation of the population. Conclusions The current feature of dose formation is the dependence of the dose of internal exposure mainly on the local particularities of the diet, and therefore, both on the socio-economic characteristics of the region / locality and the individual family.
