- Abstract: Introduction: Assessing radiation exposure is a vital step in determining the potential health risks associated with radiation and identifying the necessity for protective measures. The study assesses the occupational radiation dose encountered by undergraduate students specializing in diagnostic imaging and radiotherapy (DIR) during their clinical training in the radiology department. Materials and methods: An analysis was conducted to compare individual exposure doses with the dose limits established by the International Commission on Radiological Protection (ICRP), concurrently assessing the variations in mean effective doses among distinct student cohorts. Optically stimulated luminescence dosimeters (OSLD) were employed to monitor 143 students across five cohorts from 2017 to 2022. The electronic Secondary Standard Dosimetry Laboratory (e-SSDL) information security management system tracked the deep (Hp(10)) and shallow (Hp(0.07)) dose equivalents of DIR students. Results: The mean values for accumulated Hp(10) and Hp(0.07) were found to be 0.51 and 0.50 mSv, respectively, averaged over 800 hours of clinical training. The highest recorded exposure was 1.30 mSv, signifying that the radiation exposure experienced by DIR students was well below the threshold. The mean annual effective radiation dose per student amounted to 0.17 mSv. Small but significant difference (p < 0.001) in the radiation exposure between five cohorts was observed with increments over a 5-year period. Conclusion: The students' radiation dose was notably below the ICRP dose limit of 6 mSv/ year designated for trainees. These results indicate the efficacy of the existing radiation protection measures during clinical training, reducing the likelihood of overexposure
