一九七六年以来,我们根据X射线与物质相互作用的特性,初步探索了应用组合多层材料进行医用X射线防护问题。现将方法和效果介绍如下。选材和制做医用X射线的防护,由于工作人员和患者大多是在放射环境内(它不同于工业的隔室屏蔽防护),因此室内的建设材料必须能尽 Since 1976, based on the characteristics of the interaction between X-ray and matter, we initially explored the application of composite multilayer materials for medical X-ray protection. Now the method and effect are described below. Selection and manufacture of medical X-ray protection, as the staff and patients are mostly in the radioactive environment (it is different from the industrial compartment shielding), so the building materials must be done indoors
