Problems of verification of information on medical exposure doses in Form No. 3-DOZ and suggestion for their solution

The article analyzes the data of the federal state statistical observation form No. 3-DOZ for 2022-2023, which revealed a significant increase in medical radiation doses to patients in the Russian Federation, especially in Khabarovsk Krai. The purpose of the examination was to develop a methodology for verification of these data at the regional level. Materials and Methods: The methods of calculation of the average effective dose and comparison with reference values of the Research Institute of Radiation Hygiene after Professor P.V. Ramzaev were used. Results and Discussion: The results showed that abnormally high average effective doses were recorded in medical organizations of Khabarovsk Krai, significantly affecting the collective dose of the region. An algorithm for detecting such anomalies to optimize radiation safety was proposed. Conclusion: It was found that the current format of Form No. 3-DOZ does not allow to accurately determine the causes of deviations due to the lack of data at the level of individual devices.
