This article is focused on occupational radiogenic brain tumors and some radioprotective techniques used to manage this risk. Published case reports have stimulated concern among operators. The anatomical pattern of tumor locations is not consistent with measured radiation dose distributions at operators' heads. In addition, the lack of statistically positive findings in these reports, and a recently published survey on radiologist's mortality both indicate that the current level of fluoroscopists' radiation safety practices is likely to be adequate. This presumes that the rules of dose-management, time, distance, and shielding continue to be followed. These are briefly reviewed in this article. The use of radioprotective surgical caps is a current fashion. In clinical practice, these caps provide minimal reductions in brain dose and might induce operators to neglect applying the practical rules mentioned above. Appropriate management of personal, staff, and patient risk should always be on the radiologists' mind.
本文聚焦于职业性放射性脑肿瘤以及一些用于管理此类风险的辐射防护技术。已发表的病例报告引发了操作人员的担忧。肿瘤位置的解剖学模式与操作人员头部所测辐射剂量分布不一致。此外，这些报告中缺乏统计学上的阳性发现，以及最近发表的一项关于放射科医生死亡率的调查均表明，当前透视操作人员的辐射安全措施水平可能是足够的。这假定剂量管理、时间、距离和屏蔽规则仍在遵循。本文将对这些规则进行简要回顾。使用放射性防护手术帽是当前的一种风尚。在临床实践中，这些帽子对脑部剂量的降低作用极小，并且可能会促使操作人员忽视应用上述实用规则。放射科医生应始终牢记对个人、工作人员和患者风险进行恰当管理。
