目的了解我市常见的三类介入放射学第一术者的职业照射剂量分布,评估介入放射工作人员的职业照射风险。方法收集2家医院心脏、肝脏、下肢等三类介入手术65例。利用热释光探测器对第一术者眼睛、甲状腺、躯干、四肢等8个部位进行单次介入手术剂量测量。结果不同介入手术中,射频消融术第一术者的平均剂量最大(中位值为88μSv),下肢静脉造影剂量最小(中位值为18μSv)。常见三类介入谢射学手术的剂量分布为心脏介入剂量(中位值为56μSv)>肝脏介入剂量(中位值为29μSv)>下肢介入剂量(中位值为18μSv)。第一术者左手的剂量最大(中位值为104μSv),右脚剂量最小(中位值为11μSv)。结论应加强介入放射学的辐射防护,确保介入放射工作人员的职业安全。
Objective To understand the occupational exposure dose distribution of the first three types of interventional radiology workers in our city and evaluate the occupational exposure risk of interventional radiation workers. Methods Totally 65 cases of three kinds of interventional surgery, heart, liver and lower limb were collected in 2 hospitals. A single interventional surgery dose measurement was performed on 8 sites of the first surgeon, including the eyes, thyroid gland, trunk, and extremities, using a thermoluminescence detector. Results The average dose of radiofrequency catheter ablation was the highest among all the interventional procedures (median, 88μSv) and the lowest venous angiography (median, 18μSv). The three most common types of interventional gastrectomy interventions are the cardiac intervention dose (median 56 μSv)> liver intervention dose (median 29 μSv)> lower limb intervention dose (median 18 μSv). The first surgeon left the largest dose (median 104μSv), right foot dose minimum (median 11μSv). Conclusion Radiation protection of interventional radiology should be strengthened to ensure the occupational safety of interventional radiologists.
