This document specifies additional procedures and data for the calibration of dosemeters and doserate meters used for individual and area monitoring in radiation protection. The general procedure for the calibration and the determination of the response of radiation protection dose(rate)meters is described in ISO 29661 and is followed as far as possible. For this purpose, the photon reference radiation fields with mean energies between 8 keV and 9 MeV, as specified in ISO 4037-1, are used. In Annex D some additional information on reference conditions, required standard test conditions and effects associated with electron ranges are given. For individual monitoring, both whole body and extremity dosemeters are covered and for area monitoring, both portable and installed dose(rate)meters are covered. Charged particle equilibrium is needed for the reference fields although this is not always established in the workplace fields for which the dosemeter should be calibrated. This is especially true at photon energies without inherent charged particle equilibrium at the reference depth d, which depends on the actual combination of energy and reference depth d. Electrons of energies above 65 keV, 0,75 MeV and 2,1 MeV can just penetrate 0,07 mm, 3 mm and 10 mm of ICRU tissue, respectively, and the radiation qualities with photon energies above these values are considered as radiation qualities without inherent charged particle equilibrium for the quantities defined at these depths. This document also deals with the determination of the response as a function of photon energy and angle of radiation incidence. Such measurements can represent part of a type test in the course of which the effect of further influence quantities on the response is examined. This document is only applicable for air kerma rates above 1 µGy/h. This document does not cover the in-situ calibration of fixed installed area dosemeters. The procedures to be followed for the different types of dosemeters are described. Recommendations are given on the phantom to be used and on the conversion coefficients to be applied. Recommended conversion coefficients are only given for matched reference radiation fields, which are specified in ISO 4037-1:2019, Clauses 4 to 6. ISO 4037‑1:2019, Annexes A and B, both informative, include fluorescent radiations, the gamma radiation of the radionuclide 241Am, S-Am, for which detailed published information is not available. ISO 4037-1:2019, Annex C, gives additional X radiation fields, which are specified by the quality index. For all these radiation qualities, conversion coefficients are given in Annexes A to C, but only as a rough estimate as the overall uncertainty of these conversion coefficients in practical reference radiation fields is not known. NOTE The term dosemeter is used as a generic term denoting any dose or doserate meter for individual or area monitoring.

<p> La présente partie de l'ISO 4037 traite de l'étalonnage des dosimètres et débitmètres, utilisés pour les surveillances individuelle et de zone, dans des champs de rayonnements photoniques de référence d'énergies moyennes comprises entre 8 keV et 9 MeV (voir ISO 4037-1). Pour la surveillance individuelle, les dosimètres «corps entier» et d'extrémités sont concernés, tandis que pour la surveillance de zone, les dosimètres portables et à poste fixe sont considérés. La présente partie de l'ISO 4037 traite aussi de la détermination de la réponse en fonction de l'énergie des photons et de l'angle d'incidence du rayonnement. De tels mesurages peuvent représenter une partie d'un essai de type au cours duquel on examine l'effet d'autres grandeurs d'influence sur la réponse.La présente partie de l'ISO 4037 ne traite pas de l'étalonnage in situ de dosimètres de zone à poste fixe, qui fera l'objet d'une Norme internationale ultérieure.La présente partie de l'ISO 4037 décrit les procédures à suivre pour les différents types de dosimètres et donne des recommandations sur le fantôme à utiliser et les coefficients de conversion à appliquer. De plus, elle donne des indications sur l'analyse des incertitudes et sur la préparation des fiches et certificats d'étalonnage.NOTE 1 Le terme dosimètre est utilisé en tant que terme générique qualifiant tout dosimètre ou débitmètre pour les surveillances individuelle et de zone.NOTE 2 Dans la présente partie de l'ISO 4037, sauf indication contraire, le terme kerma signifie kerma dans l'air en champ non perturbé (free in air). </p>
