This study aimed to investigate national incidents related to medical radiation practices in Saudi Arabia from 2015 to 2019, and the actions taken to deal with these cases. The radiation protection program of the Saudi Ministry of Health monitors occupational doses for medical staff. When the radiation doses exceed the assigned investigation levels, an investigation protocol should be followed to identify the reasons and present recommendations. A total of 96 cases of radiation doses were above the investigation levels; 70% above level I, and 30% above level II. These cases were found to be 44% overload exposure, 32% intentional exposure, 8% accidental/unintentional exposure and 16% dosimeter misadventure. The majority of cases (80%) were in 2015 and 2016 with a significant drop in cases following these 2 years mainly due to continuing education and training. Investigations of incidents and the actions taken contributed to improving the radiation protection program.

沙特阿拉伯医疗实践相关职业辐射剂量事件的调查

本研究旨在调查 2015 年至 2019 年沙特阿拉伯与医疗辐射实践相关的国家事件，以及为处理这些事件而采取的行动。沙特卫生部的辐射防护计划监测医务人员的职业剂量。当辐射剂量超过指定的调查水平时，应遵循调查协议以确定原因并提出建议。共有96例辐射剂量超过调查水平；一级以上70%，二级以上30%。发现这些案例是 44% 的过载暴露、32% 的故意暴露、8% 的意外/无意暴露和 16% 的剂量计事故。大多数案例（80%）发生在 2015 年和 2016 年，这两年之后案例显着下降，主要是由于继续教育和培训。事故调查和采取的行动有助于改进辐射防护计划。
