The increase in the amount of radioactive materials administered to patients as well as the number of procedures performed has focused attention on the issue of radiation exposure to the hands of workers in nuclear medicine departments worldwide. The study aims to estimate the equivalent doses to the hands of individuals in nuclear medicine departments in Saudi. A cross-sectional analysis was conducted for 404 annual dose records in 16 nuclear medicine departments from 2016 to 2019. The monitoring of individual doses to the hands was performed using a Harshaw ring dosemeters. During the study period, the average annual equivalent doses per handled activity ranged from 0.21 to 0.41 μSv/GBq. The estimated annual activities of radiopharmaceuticals ranged from 2 to 930 MBq per exam. The hand dose averaged over the 4-year study period was determined to be 1.81 ± 0.25 mSv. The collective annual hand dose increased by 265% from 2016 to 2019.

沙特阿拉伯核医学技术人员的手部暴露分析

给予患者的放射性物质数量的增加以及所执行的程序数量的增加已将注意力集中在全球核医学部门工作人员手中的辐射照射问题上。该研究旨在估计沙特核医学部门人员手中的等效剂量。对 2016 年至 2019 年 16 个核医学科室的 404 份年度剂量记录进行了横断面分析。使用 Harshaw 环形剂量计对手的个人剂量进行监测。在研究期间，每次处理活动的平均年当量剂量范围为 0.21 至 0.41 μSv/GBq。放射性药物的估计年度活动范围为每次检查 2 到 930 MBq。4 年研究期间的平均手部剂量确定为 1.81 ± 0.25 mSv。从 2016 年到 2019 年，集体年手剂量增加了 265%。
