Objective: To monitor and analyze the protection effect of protective appliance to operators in Cardiovascular Interventional Procedures and to provide a basis data for radiation protection of operators. Methods:TLD dosimeters were used to measure the protection effect of lead rubber apron of the first operator, the second operator and nurse in cardiovascular interventional procedures. The protection effect of lead screen and lead curtain also was measured. Results:The dose of outer lead rubber apron was obviously higher than inner. The attenuation ratio of lead rubber apron for the first operator was 91.1%;the attenuation ratio of lead rubber apron for the second operator was 88.6%;the shielding efficiency of lead rubber apron was obvious. The attenuation ratio of lead screen on the treatment couch was 96.0%. The attenuation ratio of lead curtain beside the treatment couch was 97.0%. Conclusion:The radiation protective facility and measure was effective in Cardiovascular Interventional Procedures.%目的：对心血管介入手术中操作者辐射剂量控制措施与设施防护效果进行监测与评价，获取对心血管介入手术辐射防护设计有意义的数据。方法：将热释光剂量计(TLD)元件分别放置于第一术者、第二术者和护理人员的铅衣内侧以及铅衣外侧，对铅衣屏蔽效果进行测量；通过在诊疗床上铅屏内侧以及外侧、床侧铅帘内侧以及外侧放置TLD元件，对其诊疗床铅屏、铅帘的防护效果进行测量。结果：第一术者与第二术者胸部铅衣外侧的剂量大于内侧，说明铅衣发挥了屏蔽散射X射线的作用。第一术者铅衣对射线的衰减率为91.1%，第二术者为88.6%。固定防护设施床上铅屏对射线的衰减率为96.0%，床侧铅帘对射线的衰减率为97.0%。结论：心血管介入手术现场的辐射防护措施与设施是有效的。
