目前我军医疗单位装备的医用诊断 X 线机数量较大,机器的种类型号几十种。从机器的使用情况来看,最长的已达30年之久。由于机器本身防护性能较差,使专业人员的身体健康受到影响,甚而造成不良后果。同时,使患者接受的 X 线剂量也较大。鉴于 X 线机防护性能在 X 线防护工作中的重要作用,我们不能不重视现在正在使用而不符合防护要求(国家规定的标准)的 X 线机改进工作。因此,我们认为必须以管球窗口为中心进行防护改进,这样才
At present, our military medical units are equipped with a large number of medical diagnostic X-ray machines and dozens of types of machines. From the use of the machine point of view, the longest has reached 30 years. Due to the poor protective performance of the machine itself, the physical health of professionals is affected, with even adverse consequences. At the same time, patients receive a larger X-ray dose. In view of the important role of X-ray machine protection in X-ray protection work, we can not but pay attention to the improvement of X-ray machines which are being used now and do not meet the protection requirements (national standards). Therefore, we think it is necessary to improve the protection with the tube window as the center
