scope:

This Standard specifies the calibration method of dose-equivalent (rate) meter used for area monitoring and individual monitoring for radiation protection and used for setting up the air kerma reference field in the photon energy range 8 keV to 9 MeV and at air kerma rates from 10 µ Gy· h^-1 to 10 Gy· h^-1. This Standard also specifies the test methods of the response as a function of photon energy and angle of radiation incidence. This Standard is also applicable to an air absorbed dose (rate) meter, an air kerma (rate) meter and an exposure (rate) meter.
