Abstract

The evaluation of occupational exposure to external ionizing radiation in diagnostic and therapeutic applications is essential for understanding regulatory compliance and technological progress. This research presents an analysis of occupational radiation exposure in the Radiotherapy, Dental department of Usman Danfodiyo University Teaching Hospital (UDUTH) Sokoto, comparing it with relevant studies. A total of 19 Radiotherapists, each assigned a TLD code instead of worker names. Various parameters, including Average Annual Effective Dose (AAED), Annual Collective Dose (ACD), Individual Distribution Ratio (NRE), Collective Dose Distribution Ratios (SRE), and Probability of Cancer Lifetime Risks (LFTR), were analyzed using SPSS version 21.0. For Radiotherapy workers, the AAED was 1.35 ± 0.73 mSv, with an ACD of 25.66 ± 0.73 man mSv. The NRE and SRE indicated that 46.88% of received doses exceeding 1 mSv, while none exceeded 10 and 15 mSv. The LFTR for all medical radiation workers at UDUTH was less than 1mil, suggesting low cancer lifetime risks.
