This article presents information about occupational external and internal radiation of personnel in 2020 including NPP in territories monitored by the Federal Medical Biological Agency of Russia. A quantitative distribution is given for 532 facilities operating with a source of ionizing radiation in terms of departmental affiliation and activity type. The radiation dose of personnel is grouped according to the departmental affiliation of the facilities. The parameters of dose distributions are calculated: mode, median, average, standard deviation, quantile, and variation coefficient. The distribution of the number of personnel operating with sources of ionizing radiation or exposed to ionizing radiation is presented based on dose intervals of accounting of individual radiation dose at facilities of various departmental affiliation. The collective dose is given with accounting for contribution by assigned personnel, as well as the average individual dose for NPP combined by reactor type. The radiation doses are analyzed in terms of occupation. A high amount of zero individual radiation dose at NPP is noted. A conclusion is made about the satisfactory radiation environment in facilities monitored by Federal Medical Biological Agency of Russia. Radiation doses of personnel in 2013 and 2017 are compared with data of other countries: France, the United States, Germany, Great Britain, and China.
