Surface dose monitoring in patients and physicians during 29 uterine artery embolisation (UAE) procedures was performed using photoluminescence dosemeters and thermo-luminescence dosemeters. Organ or tissue doses were measured with an anthropomorphic phantom using UAE exposure conditions averaged from the 29 cases, and effective doses were estimated for the patient. Entrance surface dose of the patients at the maximum dose position ranged from 121.5 to 1650 mGy. Estimated doses ranged from 3.16 to 43 mGy for the ovary and from 3.8 to 51.8 mGy for the uterus. The effective dose was 1.09-14.8 mSv. Monitored doses on the body surface of physicians were relatively high in the upper arm (5.41+/-1.52 to 163+/-17.25 microGy) and the hand and fingers (0.85+/-1.18 to 222+/-16.4 microGy).
在29例子宫动脉栓塞术（UAE）过程中，使用光致发光剂量计和热释光剂量计对患者和医生进行表面剂量监测。使用从29例病例中平均得出的UAE暴露条件，通过人体模型测量器官或组织剂量，并估算患者的有效剂量。患者在最大剂量位置的体表入口剂量范围为121.5至1650 mGy。卵巢的估计剂量范围为3.16至43 mGy，子宫的估计剂量范围为3.8至51.8 mGy。有效剂量为1.09 - 14.8 mSv。医生体表监测到的剂量在上臂（5.41±1.52至163±17.25 μGy）以及手部和手指（0.85±1.18至222±16.4 μGy）相对较高。
