Radiation Dose of the Population in 2020

The information on the radiation situation and radiation doses of the population received in 2020 in the territories serviced by the FMBA of Russia is presented. It was based on analysis, processing and generalization of data from radiation-hygienic passports of enterprises and territories serviced by the FMBA of Russia for 2020. The values of the average annual individual radiation dose of the population in 2020 due to the natural and technogenically altered radiation background are given. Information on the structure, number of radiological procedures by types and groups of organs, collective and average radiation dose of patients received in 2020 in the territories served by the FMBA of Russia is presented. Fluorograms and radiographs dominate the quantitative ratio. There is a significant decrease in the number of X-ray procedures in 2020 compared to 2018, primarily due to a decrease in the number of fluorography and radiography procedures. At the same time, compared to 2018, the collective dose has significantly increased, and the average dose for all procedures has increased, which is associated with a significant increase in computer tomography procedures. The structure of medical irradiation of patients in the institutions of the FMBA of Russia in 2020 is given. There is a significant increase in the contribution of computer tomography in terms of the collective dose compared to previous years (more than a twenty percent increase from 2018 to 2020), with an insignificant contribution in terms of the number of procedures. The reason is a significant increase in tomographic studies during the coronavirus pandemic. The analysis of radiation doses obtained during fluorography, radiography, fluoroscopy, tomography and other procedures was carried out. The comparison of dose characteristics in diagnostic X-ray radiological procedures in Russia and France was carried out.
