The article presents estimates of the average radiation doses of 131I in the thyroid gland (thyroid gland) of people of different ages who lived in the settlements of the Bryansk, Tula, Orel and Kaluga regions in 1986, most polluted with radioactive fallout due to the accident at the Chernobyl nuclear power plant. The doses were calculated in accordance with the guidelines MU 2.6.1.1000-00 "Reconstruction of the radiation dose of iodine radioisotopes in the thyroid gland of residents of settlements of the Russian Federation exposed to radioactive contamination as a result of the Chernobyl nuclear power plant accident in 1986" approved by the Russian Ministry of Health on 29.10.2000. In the calculations of the Directory, the values ​​of dose factors (absorbed dose in the body per unit of intake of activity into the body) recommended by the ICRP for persons of different ages are used. The tables of the Directory contain estimates of average doses for all NPs in the four oblasts that are included in the "List of Populated Areas Within the Radiation Contamination Zones Due to the Chernobyl Disaster" approved by the Government Decree of 18.12.1997 Pollution of the soil 137Cs in 1986 for these settlements was estimated based on soil contamination data provided by RosKydromet as of January 1, 2001. Total thyroid dose was estimated for 973 settlements of Bryansk region, 351 settlements of Kaluga region, 900 settlements of Orel region and 1305 settlements of Tula region. At the present time this edition most fully summarizes the available radiation monitoring data in the areas in question in 1986. However, the dosimetry data can be refined as additional results of historical or modern radioecological studies are received or more sophisticated techniques for reconstructing the dose of internal radiation thyroid gland.
