This study aimed to provide basic data on the probabilistic effects of radiation by measuring the radiation exposure dose of radiation workers and radiological technology student participating in clinical practice at C University Hospital in Incheon City and analyzing the incidence rate. The subjects of the study were 10 nuclear medicine technologists and 15 radiation oncology worker who worked in the radiological technology area of C University Hospital in Incheon City from January 1, 2023 to December 31, 2023, and 82 radiological technology student who completed the clinical practice course at the same medical institution from July to August. The incidence of adverse effects on the lungs due to radiation exposure dose of radiation oncology worker was shown to be 2.5 per 10,000,000 people for both shallow and deep doses. The nuclear medicine department showed a shallow dose of 2.90 ± 0.61 mSv and a deep dose of 3.02 ± 0.63 mSv, indicating an occurrence probability of 1.5 per 100,000 people. In addition, the radiological technology student classified as frequent visitors showed a shallow dose of 0.99 ± 0.12 mSv and a deep dose of 0.97 ± 0.11 mSv, indicating an occurrence probability of 6.8 and 6.6 per 1,000,000 people. It is thought that this will serve as basic data for minimizing individual exposure dose for radiation workers and analyzing the safety management and probabilistic effects of radiation.
