X线检查是人群受人工辐射照射量比重最大的辐射源,占人工辐射源照射剂量的90％。做好X线防护工作不但能减少工作人员的受照剂量,免除射线危害,有利于 X线诊断技术的推广和应用,也关系到受检者的安全与健康问题。我们根据1985年8～11月对驻南宁市的区直各医院及部队、企事业单位的医院(所)共26个单位使用的73台X线机(其中≤100mA22台,200～400mA 37台,≥500mA14台)以及73间机房等防护设施的调查资料进行总结分析,提出今后防护工作的重点。 X线机和设施防护的现状与分析:按“医用诊断X线卫生防护规定”的要求与测试方法,用XS-1型X线巡测仪对不同检查项目的操作位的照射量率进行监测,并丈
X-ray examination is the population by artificial radiation exposure the largest proportion of radiation sources, accounting for artificial radiation dose 90%. Doing a good job of X-ray protection can not only reduce the doses of staff members and eliminate the radiation hazards, but also promote the popularization and application of X-ray diagnostic techniques as well as the safety and health problems of the subjects. According to 73 X-ray machines (including ≤100mA22 units and 200 ~ 400mA units) used by 26 units in hospitals and military hospitals and units in Nanning City from August to November 1985, , ≥ 500mA14 Taiwan) and 73 room and other protective equipment survey data summary analysis, put forward the focus of future protection work. Current status and analysis of X-ray machine and facility protection: According to the requirements and test methods of “X-ray health protection requirements for medical diagnosis”, the XS-1 type X-ray detector is used to monitor the exposure rate of operation positions of different inspection items , And husband
