OCCUPATIONAL DOSES TO RADIOGRAPHY INTERNSHIP STUDENTS IN SAUDI ARABIA USING OPTICALLY STIMULATED LUMINESCENCE...

This study aimed to estimate a baseline for the effective doses received by radiography internship students in Saudi Arabia. A retrospective study was conducted from 2015 to 2018 to discern the effective dose measurements for a total of 206 students using optically stimulated luminescence dosemeters. Readings were performed using the OSLR-250 Automatic Reader. Data analysis was carried out on 813 readouts. The annual mean effective dose averaged over a period of 4 y was found to be 0.55 mSv, with a standard deviation of 0.34 mSv and a range of 0.14-1.58 mSv. The results show that 92% ($\frac{190}{206}$) of the students received annual effective doses of <1 mSv. No annual dose record exceeded the limits recommended by authorities (20 mSv/y). The study concluded that the applied radiation protection measures along with education and training help create a safe work environment for radiography internship students.
