摘要
目的 了解浙江省介入放射学放射防护现状和存在的问题，并提出相应对策。方法 采用简单随机抽样的方法在杭州、宁波、温州、绍兴、金华5个地市抽取70个介入放射工作场所进行监测，医院介入放射机房个人防护用品和辅助防护设施采用医院填报的方法收集，透视防护区工作人员各部位和机房外辐射水平采用现场辐射水平检测的方法收集。结果 41家医院均配备了个人防护用品和个人防护设施，但有22家医院配备不完整；下X射线管照射时，介入放射工作人员的胸部、腹部、下肢部比头部更容易受到大剂量的射线照射，差异有统计学意义（F=4.85、4.92，P〈0.05）；透视防护区工作人员各部位辐射水平合格率不同，差异有统计学意义（χ2=35.14、14.92，P〈0.05）；防护吊帘可以显著降低透视防护区工作人员各部位辐射水平，差异有统计学意义（t=11.61-68.28，P〈0.05）；同时，防护吊帘可以提高透视防护区工作人员各部位的检测合格率，差异有统计学意义（χ2=6.09-28.45，P〈0.05）。结论 介入放射工作人员应该充分利用辅助防护设备，加强对胸部、腹部和下肢部等部位的保护；医院必须积极开展放射工作场所的日常监测，及时对防护薄弱环节进行整改。
Objective To explore the current status of radiation protection in interventional procedure and to analyze the existent problems. Methods Using the random sampling, 70 interventional radiology workplaces were selected from Hangzhou, Ningbo, Wenzhou, Shaoxing and Jinhua. Information on personal radiation protective products and equipment was collected by filling out the form by hospital and the radiation dose was monitored at various body parts of the workers and at the outside of the operating room. Results All hospitals have been equipped with personal radiation protective products and equipment, 22 of which were not with these products and equipment as required. Chest, abdomen and lower limb of interventional radiology workers are easy to receive higher radiation dose than in head （F=4.85,4.92,P〈0.05）. The acceptance rates among different body parts of the workers were difference significantly （χ2=35.14,14.92, P〈0.05）. Using protective curtain can reduce the radiation dose significantly （t=11.61-68.28,P〈0.05）. Meanwhile, it also can improve the acceptance rates significantly （χ2=6.09-28.45,P〈0.05）. Conclusions It is necessary to strengthen the use of radiation protection equipment among interventional radiology workers to reduce the levels of the individual doses to them.Hospitals must enhance the routine monitoring for improved radiaton protection.
