In recent years, the use of radiation diagnostic methods in medical examinations of both the Russian Federation population and personnel working with man-made radiation sources has increased, with a large proportion of these being computed tomography (CT), which incurs additional radiation exposure to the individuals being examined 1–3. This has resulted in a significant increase in the contribution of CT to the collective patient dose—from 54.38% in 2018 to 73.83% in 2020 and 68.8% in 2022 4. For the period 2020–2024, the main contributors to the morbidity structure according to CT without CE were respiratory diseases (41.4%) and neoplasms (13.1%). For CT with CE, the greatest contribution was made by neoplasms (48.3%) and circulatory diseases of types 100–199 (14.1%). The average radiation dose during the study period for CT without CE varied depending on the class from 2.22 to 10.54 mSv, while for CT with CE, it ranged from 8.2 to 34.33 mSv, significantly exceeding occupational radiation doses in industrial settings (0.35–2.41 mSv). Peculiarities in the pattern of illnesses among workers referred for CT examinations were identified, depending on their age and gender. This is important to consider when developing recommendations for optimizing radiation diagnostic methods.
