Analysis on current situation of radiological protection in state-owned and private medical institutions in Dalian

目的了解大连市2013年国营和私营医疗机构的放射防护现状,为卫生行政部门放射卫生管理提供依据。方法按照国家相关法规、标准对医用诊断X射线放射防护规定的内容、工作场所的辐射水平以及放射工作人员个人剂量监测与防护等情况进行调查。结果 X射线机的主要防护性能合格率：国营为97.4%,私营为85.7%。机房X射线泄露辐射水平大于本底辐射水平：国营为3.5%,私营为9.5%;近1年的放射工作人员个人剂量监测结果：15 m Sv：国营为86.9%,私营为82.9%;25-15 m Sv：国营为13.1%,私营为9.8%;315-20 m Sv：国营为0,私营为4.9%;4〉20 m Sv：国营为0,私营为2.4%。培训率和持证率：国营为100%,私营为95%。职业健康体检率：国营为100%,私营为91.3%。建档率：国营为100%,私营为97.5%。个人剂量监测率：国营为100%,私营为97.5%。个人防护用品配置率：国营为100%,私营为93.8%。个人防护用品的使用率：＂经常使用＂：国营为48.2%,私营为10.4%,＂偶尔使用＂：国营为41.2%,私营为46.9%;＂从不使用＂：国营为4.6%、私营为42.7%。结论该市国营和私营医疗机构的放射防护状况总体上比较好,但私营医疗机构相对较差一些,相关行政管理部门应加强对私营医疗机构的监督管理。

[Objective]To understand the current situation of radiological protection in state-owned and private medical institutions in Dalian in 2013,provide basis for radiological health management of health administrative department.[Methods]The content of medical diagnostic X-ray radiation protective regulations,radiation levels in the workplaces and the situation of personal dose monitoring and protection of radiologic workers were investigated according to national relevant regulations and standards.[Results]The qualified rates of main protective performance of X-ray machines： state-owned was 97.4%, private was 85.7%.Leaked radiation level of X-ray was higher than background radiation level： state-owned was 3.5%, private was 9.5%. The monitoring results of personal dose of radiologic workers in recent 1 year：15 m Sv：state-owned was 86.9%,private was 82.9%;25-15 m Sv：state-owned was 13.1%,private was 9.8%;315-20 m Sv：state-owned was 0,private was 4.9%;420 m Sv：state-owned was 0,private was 2.4%. Training rate and the certificate holding rate：state-owned was 100%,private was 95%.The rate of occupational health examination：state-owned was 100%,private was 91.3%. Filing rate：state-owned was 100%,private was 97.5%. Personal dose monitoring rate：state-owned was 100%,private was 97.5%. Equipping rate of personal protective devices：state-owned was 100%,private was 93.8%. Using rate of personal protective devices：＂frequent using＂：stateowned was 42.8%,private was 10.4%;＂occasionally using＂：state-owned was 41.2%,private was 46.9%;＂never using＂：stateowned was 4.6%,private was 42.7%. [Conclusion]The current situation of radiological protection in state-owned and private medical institutions in Dalian is better, but private medical institutions are relatively poor,the relevant administrative departments should strengthen the supervision and administration of private medical institutions.
