Technogenic industrial exposure of personnel of radiation facilities in 2024

The purpose of this study was to analyze the radiation doses of personnel of radiation facilities in the Russian Federation in 2024 and for the period from 2019 to 2024.Data on radiation doses in 2024 were used for 239,743 personnel of group A and 22,490 personnel of group B working at 20,359 radiation facilities, of which 15,883 (78 %) were medical institutions. The average annual effective dose of technogenic industrial irradiation to Group A personnel in 2024 was 1.08 mSv, and to Group B personnel - 0.58 mSv. The average doses are quite stable for the period 2019-2024: those ranged from 1.08 to 1.19 mSv for the personnel of group A and from 0.58 to 0.66 mSv for the personnel of group B. About 10 % of the personnel of group A and about 2 % of the personnel of group B received annual individual doses of technogenic industrial radiation of more than 2 mSv. Four cases of exceeding the annual individual dose of 50 mSv for the personnel were registered in Group A in 2024. Over the past 6 years, the number of exceedances of the average annual dose limit for Group B personnel (91) has almost doubled the same amount for Group A personnel (50), although the number of group B personnel for whom individual dosimetric monitoring is carried out is significantly less than the number of Group A personnel. This is mainly the case for the personnel of group B medical institutions involved in X-ray-controlled operations. It is necessary to make individual dosimetric monitoring mandatory for this category of Group B personnel. In general, the Russian Federation ensures socially acceptable level of radiation safety for personnel at radiation facilities.
