摘　　要：目的选取介入放射学中较常见的脑血管、心血管和肝脏介入诊疗，估算以上3种介入诊疗中放射工作人员的有效剂量。方法通过仿真人体模型实验，了解脑血管、心血管、肝脏介入诊疗中仿真体模内组织、器官的吸收剂量，并根据ICRP103号出版物中规定的组织权重因子估算3种介入诊疗中放射工作人员的有效剂量。结果脑血管介入诊疗时，介入放射工作人员的有效剂量分别为高剂量组24．0μSv、中剂量组9．7μSv、低剂量组6．8μSv；心血管介入诊疗时，放射工作人员的有效剂量分别为高剂量组36．3μSv、中剂量组29．3μSv、低剂量组17．8μSv；肝脏介入诊疗时，放射工作人员的有效剂量分别为高剂量组23．9μSv、中剂量组11．3μSv、低剂量组5．5μSv。结论心血管介入诊疗中放射工作人员高、中、低3个剂量组的有效剂量分别高于脑血管和肝脏介入诊疗时相应剂量组的有效剂量。Objective To study and estimate the effective dose of interventional employees in the common eerebralvascular, cardiovascular and liver interventional diagnosis and treatment. Methods The absorbed doses of tissue or organ of anthropomorphic phantom in these three procedures were estimated by the anthropomorphic phantom experiment. The effective doses were calculated by the tissue weight factor which was given by International Commission on Radiological Protection publication 103. Results The effective doses to high, medium and low group were 24. 0, 9.7,6.8 μSv for cerebralvascular interventional diagnosis and treatment, and 36. 3, 29.3, 17.8 μSv for cardiovascular interverttional diagnosis and treatment, and 23.9, 11.3, 5.5 μSv for liver interventional diagnosis and treatment, respectively. Conclusions The effective doses of high, medium and low group of interventional employees in cardiovascular interventional procedure are higher than those of cerebralvaseular and liver interventional procedures.
