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 µGy) and the hand and fingers (0.85 ± 1.18 to 222 ± 16.4 µGy).
