Abstract

Nuclear medicine (NM) and positron emission tomography/computed tomography (PET/CT) personnel are daily exposed to radiation dose, their protection being crucial. This study of occupational doses within the NM and PET/CT department of a large Riyadh tertiary covers the period 2019 to 2022. Calibrated optically stimulated luminescence dosimeters (OSLD) were utilized to determine personal dose equivalent Hp(10). Both departments perform a wide range of adult and paediatric examinations, involving 18 technologists, 4 NM physicians, 2 nurses and 2 medical physicists; quoted in mSv. The average annual whole-body occupational radiation exposure for technologists, nurses, medical physicists and NM physicians over 4 years was 0.72, 0.94, 0.51 and 0.16 mSv, respectively. The reported annual occupational whole-body exposure for NM staff groups were in the acceptable range of published peer-reviewed data in the literature. However, a careful evaluation of working conditions for the nurse group is recommended to further minimise the radiation doses attributed to the recent increase in the number of single photon emission computed tomography (SPECT) and PET diagnostic workload examinations. However, annual staff doses were found to be below the value recommended by the International Commission on Radiological Protection (ICRP).

核医学和PET/CT中心专业人员的职业辐射剂量评估

核医学（NM）和正电子发射断层扫描/计算机断层扫描（PET/CT）人员每天都暴露在辐射剂量下，其防护至关重要。这项对利雅得一所大型高等学校的NM和PET/CT部门的职业剂量的研究涵盖了2019年至2022年。使用校准的光激发发光剂量计（OSLD）来确定个人剂量当量Hp（10）。两个科都进行广泛的成人和儿科检查，涉及18名技术人员、4名产科医生、2名护士和2名医学物理学家；以mSv引用技师、护士、医学物理学家和内科医生4年平均年全身辐射暴露量分别为0.72、0.94、0.51和0.16毫西弗。报告的NM工作人员群体的年度职业全身暴露量在文献中已发表的同行评审数据的可接受范围内。然而，建议对护士组的工作条件进行仔细评估，以进一步减少由于最近单光子发射计算机断层扫描（SPECT）和PET诊断工作量检查数量的增加而导致的辐射剂量。然而，工作人员的年剂量被发现低于国际放射防护委员会建议的值。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
