X and gamma reference radiation for calibrating dosemeters and doserate meters and for determining their response as a function of photon energy -- Part 4: Calibration of area and personal dosemeters in low energy X reference radiation fields
This standard was last reviewed and confirmed in 2014. Therefore this version remains current.
ISO 4037-4:2004 gives guidelines on additional aspects of the characterization of low energy photon radiations. ISO 4037-4:2004 also describes procedures for calibration and determination of the response of area and personal dose(rate)meters as a function of photon energy and angle of incidence. ISO 4037-4:2004 concentrates on the accurate determination of conversion coefficients from air kerma to Hp(10) and H*(10) for the spectra of low energy photon radiations. As an alternative to the use of conversion coefficients, the direct calibration in terms of these quantities by means of appropriate reference instruments is described.
