两间专门用于血管和内脏介入放射学手术的 X 射线室发生了几起经眼科证实的晶状体损伤病例，这些病例是由职业辐射暴露引起的。两个实验室都配备了不是为介入放射学设计的卧式 X 射线系统，也没有用于眼睛辐射防护的专用工具。典型的工作量范围为每天两到五个程序。对于受影响的两名放射科医生来说，几年来，眼晶状体受到的剂量估计为每年 450 至 900 毫西弗。一旦发现事件，两个房间的 X 射线系统都被拆除，并安装了专门为介入放射学设计的新设备，包括悬挂的屏蔽屏。由于这些镜片损伤只是偶然发现的，因此讨论了避免将来发生类似情况的措施。
Several cases of ophthalmologically confirmed lens injuries, caused by occupational radiation exposure, have occurred in two X-ray rooms devoted to vascular and visceral interventional radiology procedures. Both laboratories were equipped with overcouch X-ray systems not designed for interventional radiology and without specific tools for radiation protection of the eyes. Typical workloads ranged from between two and five procedures per day. For the two radiologists affected, estimates for the dose to eye lens ranged from 450 to 900 mSv per year, over several years. Once the incidents had been detected, the X-ray systems in both rooms were removed and new equipment specifically designed for interventional radiology was installed, including suspended shielding screens. Since these lens injuries were only detected accidentally, measures to avoid similar occurrences in the future are discussed.
