THE RESULTS OF FUNCTIONING OF THE UNIFIED SYSTEM OF INDIVIDUAL DOSE CONTROL OF THE RUSSIAN FEDERATION CITIZENS BASED ON THE 2017 DATA

The article presents the results of the generalized analysis of the data on staff, patient, and public doses from ionizing radiation obtained from the Unified System of Individual Dose Control for 2017. The analysis is conducted on the basis of the annual data from the forms of Federal State Statistical. Observation No.1-DOZ (staff individual doses), No.2-DOZ (doses from radiation accidents), No.3-DOZ (patient doses) and No.4- DOZ (public doses from natural and technogenically impacted background). The information is submitted by the organizations and territories under the supervision of the Rospotrebnadzor and FMBA of the Russian Federation. The article is based on the data obtained within the framework of Radiation-Hygiene passportization. In 2017, 18 324 organizations working with the artificial radiation sources submitted the form No.1-DOZ. The form No.1-DOZ contains data on 235 271 staff individual doses, 215 290 of the staff group A and 19 981 the staff group B with individual monitoring. In 2017, the average individual dose for the staff group A was 1,23 mSv, the staff group B – 0,67 mSv. In 2017, 13 036 healthcare organizations submitted the form No.3- DOZ. According to the No.3-DOZ data, more than 286 mln. X-ray procedures were conducted in the Russian Federation in 2017. An average dose per capita from medical exposure was 0,55 mSv/year and a mean dose per an X-ray examination was 0,28 mSv. In 2017, the form No.4-DOZ contained data on 8 130 measurements of gamma-radiation dose rate in wooden houses, 1 557 measurements in one-storey stone houses, 126 550 measurements in multi-storey stone houses and 178 138 measurements on the open ground As well as the results of 4 417 measurements of radon concentration levels in wooden houses, 5 971 measurements in one-storey stone houses, 57 461 measurements in multi-storey stone houses. The public average effective dose from natural ionizing radiation sources corresponded to 3.34 mSv/year, the average values for the subjects of the Russian Federation fall in the range from 2,15 mSv/year (Nenets Autonomous Okrug) to 8,9 mSv/year (Altai republic). The article includes the Annexes with the final generalized forms of the Unified System of Individual Dose Control in 2017 based on the forms of statistical observations No. 1-, 3- and 4-DOZ of the subjects of the Russian Federation.
