Abstract

Nuclear medicine (NM) is an essential radiology department in healthcare facilities. In NM procedures, radioactive isotopes are administered intravenously or orally to assess the molecular, metabolic, physiologic, anatomical and pathologic states of the body for diagnostic therapy and research applications. The personal radiation dose data of 269 NM technologists and 132 nurses, all with annual dose records, from 2016 to 2021 are collected in four major medical centres. Personal radiation doses in NM departments are monitored on a quarterly basis using thermoluminescent dosimeters (TLDs). The TLDs used have an approximate tissue equivalence of 8.14 and a density of around 2.64 g cm3. TLDs are read using WinREMS software and a Harshaw 6600 plus reader. In this study, only Hp (10), which estimates the effective dose, is included in the analysis. The result showed that the NMTs and nurses’ overall mean effective dose during the study period were 1.06±0.60 mSv (0.063.26 mSv) and 0.92±0.70 mSv (0.015.52 mSv), respectively. The result of our study found lower values of annual mean effective doses compared to previous studies conducted in Saudi Arabia. The mean effective dose among both workers were below the permissible dose limits, which suggest a safe work environment in term of radiation protection practices.

沙特阿拉伯利雅得核医学工作人员辐射剂量评估

核医学(NM)是医疗机构必不可少的放射科。在纳米技术中，放射性同位素通过静脉注射或口服来评估人体的分子、代谢、生理、解剖和病理状态，用于诊断治疗和研究应用。收集了2016年至2021年四个主要医疗中心269名纳米技术人员和132名护士的个人辐射剂量数据，均有年度剂量记录。每季度使用热释光剂量计监测NM部门的个人辐射剂量。所使用的tld具有近似的组织等效性8.14，密度约为2.64 g cm−3。使用WinREMS软件和Harshaw 6600 plus阅读器读取顶级域名。在本研究中，只有估算有效剂量的Hp(10)被纳入分析。结果显示，研究期间nmt和护士的总体平均有效剂量分别为1.06±0.60 mSv(0.06±3.26 mSv)和0.92±0.70 mSv(0.01±5.52 mSv)。我们的研究结果发现，与先前在沙特阿拉伯进行的研究相比，年平均有效剂量值较低。这两名工人的平均有效剂量均低于允许的剂量限值，这表明就辐射防护措施而言，工作环境是安全的。

期刊介绍： Radioprotection publishes articles on all aspects of radiological protection, including non-ionising as well as ionising radiations. Fields of interest range from research, development and theory to operational matters, education and training. The very wide spectrum of its topics includes (theoretical and practical aspects): dosimetry, instrument development, specialized measuring techniques, epidemiology, biological effects (in vivo and in vitro) and risk and environmental impact assessments.
