Appendix A - Calibration of air kerma ratemeters

Applies to portable, transportable or installed assemblies intended to measure environmental air kerma rates from 30 nGy h-1 to 10 µGy h-1 due to X or gamma radiation of energy between 50 keV and 1,5 MeV. Specifies general characteristics, general test procedures radiation characteristics, electrical, mechanical, safety and environmental characteristics as well as the identification certificate.
