Endoscopic retrograde cholangiopancreatography (ERCP) procedure is an invasive technique that requires fluoroscopic and radiographic exposure. The purpose of this study was to determine the occupational dose of ionising radiation at three gastroenterology departments (Fedial, Soba and Ibn seena hospitals) in Khartoum, Sudan. The radiation dose was measured during 55 therapeutic ERCP procedures. Thermoluminescence dosemeters were used. The mean radiation dose for the first operator was 0.27 mGy for the eye lens, 0.21 for the thyroid, 0.32 for the chest, 0.17 for the hand and 0.22 for the leg. The mean radiation dose for the second operator was 0.21 mGy for the hand and 0.20 mGy for the chest, while the mean radiation dose for the nurse was 0.44 mGy for the hand and 0.19 for the chest. The radiation dose received by the staff in these hospitals was found to be higher than most of the values in the literature. The radiation absorbed dose received by the different organs is relatively low. Additional studies need to be conducted for radiation dose optimisation.
内镜逆行胰胆管造影术（ERCP）是一种侵入性技术，需要进行荧光透视和放射成像。本研究的目的是确定苏丹喀土穆三家胃肠病科（费迪尔医院、索巴医院和伊本·西那医院）的职业电离辐射剂量。在55例治疗性ERCP手术过程中测量了辐射剂量。使用了热释光剂量计。第一位操作人员的平均辐射剂量为：晶状体0.27毫戈瑞、甲状腺0.21毫戈瑞、胸部0.32毫戈瑞、手部0.17毫戈瑞、腿部0.22毫戈瑞。第二位操作人员的平均辐射剂量为：手部0.21毫戈瑞、胸部0.20毫戈瑞，而护士的平均辐射剂量为：手部0.44毫戈瑞、胸部0.19毫戈瑞。发现这些医院工作人员所接受的辐射剂量高于文献中的大多数值。不同器官所吸收的辐射剂量相对较低。需要进行更多研究以优化辐射剂量。
