目的掌握浙江省嘉兴市医用X射线的放射防护现状,为加强管理提供依据。方法参照国家相关标准,对该市66家医用X射线应用单位,进行放射工作场所放射防护现状调查及放射防护区辐射水平监测。结果抽查128名放射工作人员《放射工作人员证》持证率为100%;调查106台X射线机,放射室门窗屏蔽率为25.64%,防护设施完整配备率为41.03%;辐射水平监测,总合格率为83.49%,候诊区合格率仅为65.22%。结论该市放射防护的各项措施落实不到位,工作人员防护区及患者候诊区的辐射水平超标严重。加强依法管理,是做好放射防护,减少辐射危害发生的重要措施。
Objective To grasp the current situation of radiation protection of medical X-ray in Jiaxing City, Zhejiang Province, and provide the basis for strengthening management. Methods With reference to relevant national standards, 66 medical X-ray units in the city were surveyed to investigate the status quo of radiation protection in radiological workplaces and the radiation level of radiation protection areas. Results A total of 128 X-ray radiography radiologists were certified as “Radiological Worker’s Credentials” by a random sample of 100 radios. Screening rate of radiological room doors and windows was 25.64% and protection facilities were fully equipped with a rate of 41.03%. Radiation level monitoring, Pass rate was 83.49%, waiting area qualified rate was only 65.22%. Conclusion The measures of radiation protection in the city are not implemented properly, and the radiation levels of staff protection areas and patient waiting areas exceed the standard seriously. Strengthening management according to law is an important measure to prevent radiation and reduce radiation hazards.
