1 Scope

This part of ISO 4037 specifies the characteristics and production methods of X and gamma reference radiation for calibrating protection-level dosemeters and rate dosemeters at Alr kerma rates from 10 μGy·h⁻¹ to 10 Gy·h⁻¹ and for determining their response as a function of photon energy. The methods for producing a group of reference radiations for a particular photon-energy range are described in four sections which define the characteristics of these radiations. The four groups of reference radiation are:

a) in the energy range from about 7 keV to 250 keV, continuous filtered X radiation and the gamma radiation of americium-241 ;
b) in the energy range 8 keV to 100 keV, fluorescence X radiation;
c) in the energy range 600 keV to 1,3 MeV, gamma radiation emitted by radionuclides;
d) in the energy range 4 MeV to 9 MeV, gamma radiation produced by reactors and accelerators.

These reference radiations should be selected from table 1.
