Personnel Radiation Dose in 2020

Abstract

Information is provided on professional external and internal irradiation in 2020 of personnel of organizations, including nuclear power plants, in the territories serviced by the FMBA of Russia. The quantitative distribution of 532 objects operating ionizing radiation sources by departmental affiliation and type of activity is given. The radiation dose of the personnel is grouped according to the departmental affiliation of the objects. The parameters of dose distributions are calculated: mode, median, mean, mean square deviation, quantile and coefficient of variation. The distribution of the number of personnel working with ionizing radiation sources is presented according to the dose intervals for taking into account individual radiation doses at facilities of different departmental affiliation. The value of the collective dose is given, taking into account the contribution of seconded personnel, as well as the value of the average individual dose for nuclear power plants united by reactor type. The analysis of radiation doses depending on the profession was carried out. A large number of zero individual radiation doses at nuclear power plants were noted. The conclusion is made about the satisfactory radiation situation in organizations serviced by the Federal Biomedical Agency. A comparison was made with the radiation doses of personnel in 2013 and 2017 and with data for other countries: France, USA, Germany, Great Britain and China.
