The International Commission on Radiological Protection has substantially reduced the recommended maximum annual eye lens dose for workers. Use of a dedicated eye dosemeter is one method for accurate dose monitoring. The main aim of this study was to yield recommendations for optimal placement of eye dosemeters to estimate the eye dose to interventional cardiology physicians and nurses. A phantom measurement was conducted to simulate typical interventional cardiology procedures. Considering eight X-ray tube angulations, the left side of the head position provide good estimates for physician, and the forehead position provide good estimates for nurse.
国际放射防护委员会已大幅降低了对工作人员推荐的年度眼晶状体最大剂量。使用专用眼部剂量计是进行精确剂量监测的一种方法。本研究的主要目的是就眼部剂量计的最佳放置位置提出建议，以估算介入心脏病学医生和护士所接受的眼部剂量。进行了模拟典型介入心脏病学程序的体模测量。考虑到八个X射线管角度，头部位置的左侧对医生能提供较好的剂量估算，而额头位置对护士能提供较好的剂量估算。
