scope:

This International Standard constitutes a guide to defining and carrying out general methods for testing exposure meters and dosimeters used in radiation protection for X-rays and gamma rays with energies below or equal to 3 MeV. It will subsequently be complemented by a second document dealing with rate meters and, in the more distant future, by a third document relating to dosimeters used in the presence of neutrons or gamma rays with energies above 3 MeV. However, study of this latter point necessitates the parallel establishment of definitions of suitable reference radiations.
