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.

沙特阿拉伯使用光刺激发光剂量学对放射学实习学生的职业剂量

本研究旨在估计沙特阿拉伯的放射学实习学生接受的有效剂量的基线。从 2015 年到 2018 年进行了一项回顾性研究，以识别使用光激发发光剂量计的总共 206 名学生的有效剂量测量。使用 OSLR-250 自动阅读器进行读数。对 813 个读数进行数据分析。发现 4 年内平均的年平均有效剂量为 0.55 mSv，标准偏差为 0.34 mSv，范围为 0.14-1.58 mSv。结果表明，92% ($\frac{190}{206}$) 的学生接受了小于 1 mSv 的年有效剂量。年剂量记录没有超过当局建议的限值（20 mSv/y）。
