医用诊断X射线辐射防护器具 第1部分:材料衰减性能的测定

[中文适用范围]： 适用于用于制造 X 射线防护装置的片状材料，其辐射质量由 X 射线管电压高达 400 kV 和总过滤高达 3.5 mm Cu 产生。不适用于保护 [外文原描述]： Applies to materials in sheet form used for the manufacturing of protective devices against X-radiation of radiation qualities generated with X-ray tube voltages up to 400 kV and a total filtration of up to 3,5 mm Cu. This part 1 is not intended to be applied to protective devices when these are to be checked for the presence of their attenuation properties before and after periods of use.
