An The article is devoted to the peculiarities of the internal exposure dose formation in the adult population of the internal dose forming of the adult population of Russian Federation due to consumption of different foodstuffs in the remote period after the accident on at the Chernobyl NPP. Estimation of the impact of different foodstuffs is carried out in the forming of the mentioned doses; the foodstuffs mainly contributing in the internal dose forming formation are revealed. Based on the Bryansk region data, the comparing was fulfilled of the current food rations of population with the previous rations – of during the initial and intermediate postaccidental periods. It is illustrated how the differences in food rations affect the levels of exposure of the local inhabitants, which is necessary for the appropriate assessment of the internal exposure doses for population living in the contaminated territories.

The purpose of the study was to study the patterns of forming average annual and cumulative exposure doses. The subject of the study was the dynamics of the average annual and cumulative doses of the adult population of the Russian Federation after the Chernobyl nuclear power plant accident. Results and conclusions. We estimated the contribution of external and internal exposure doses accumulated during the first year after the disaster into the total doses accumulated in 1986–2016 in the population living in the areas with different levels of 137Cs activity in surface soil. The contribution of the exposure doses received during the first year after the accident into the total doses accumulated in 1986–2016 by the population of the regions with different levels of 137Cs activity in surface soil was more than 30%. The contribution of the internal exposure dose received during the first year after the accident into the total exposure dose accumulated in 1986–2016 by the population exceeded that of the external dose. We predicted the average annual and cumulative exposure doses of the population until the year 2056: in 2016, the actual average annual exposure dose for the population exceeded 1.0 mSv/year only in 19 settlements of the Bryansk Region while by 2056 the number of such settlements would be null. In 2016, the average cumulative exposure dose of the population exceeded 70 mSv in 55 settlements of the Bryansk Region, the maximum being 299 mSv. According to the forecast for the year 2056, the total number of settlements in the Bryansk Region with the average cumulative exposure dose of the population equal to or greater than 70 mSv would approach 92. All these settlements are situated only in the Bryansk Region. The maximum expected value of the average cumulative exposure dose would be 374 mSv. We estimated the contribution of the population exposure dose accumulated in 1986–2016 into the exposure dose accumulated during 70 years (a lifetime dose). The contribution of the average accumulated effective exposure dose for 1986–2016 into the dose predicted for 1986–2056 ranged 86% to 94%. This means that the major part of the lifetime dose has been already accumulated by the locals

Авария на Чернобыльской АЭС (далее-ЧАЭС) в 1986 г. привела к радиоактивному загрязнению значительных территорий европейской части Российской Федерации и сопредельных государств. В настоящее время в зонах радиоактивного загрязнения Российской Федерации на-ходится 3855 населенных пунктов (далее-НП), где проживают более 1,5 млн человек [1]. Наиболее интенсивно загрязнена Брянская область: так, в Красногорском районе до сих пор есть населенные пункты с загрязнением почвы цезием-137 более 40 Ки/км 2. Значительно пострадали также Тульская, Калужская и
