Protective devices against diagnostic medical X-radiation - Determination of attenuation properties of materials1 Scope This part of IEC 61331 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 gamma radiation emitted by radionuclides with photon energies up to 1,3 MeV. 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
