Scope

This standard applies to the calibration of portable high-range external exposure photon radiation ambient dose equivalent (rate) instruments used in radiation protection situations during emergencies. The instruments are suitable for photon radiation energy ranges of 80 keV to 1.3 MeV. The ambient dose equivalent rate H*(10) ranges from 0.1 mSv/h to 10 Sv/h.
