Nuclear energy - Reference beta-particle radiation - Part 3: Calibration of area and personal dosemeters and the determination of their response as a function of beta radiation energy and angle of incidence (ISO 6980-3:2023)
This document describes procedures for calibrating and determining the response of dosemeters and dose-rate meters in terms of the operational quantities for radiation protection purposes defined by the International Commission on Radiation Units and Measurements (ICRU). However, as noted in ICRU 56, the ambient dose equivalent, H*(10), used for area monitoring, and the personal dose equivalent, Hp(10), as used for individual monitoring, of strongly penetrating radiation, are not appropriate quantities for any beta radiation, even that which penetrates 10 mm of tissue (Emax > 2 MeV).
This document is a guide for those who calibrate protection-level dosemeters and dose-rate meters with beta-reference radiation and determine their response as a function of beta-particle energy and angle of incidence. Such measurements can represent part of a type test during the course of which the effect of other influence quantities on the response is examined. This document does not cover the in-situ calibration of fixed, installed area dosemeters. The term “dosemeter” is used as a generic term denoting any dose or dose-rate meter for individual or area monitoring. In addition to the description of calibration procedures, this document includes recommendations for appropriate phantoms and the way to determine appropriate conversion coefficients. Guidance is provided on the statement of measurement uncertainties and the preparation of calibration records and certificates.
Énergie nucléaire - Rayonnement bêta de référence - Partie 3: Étalonnage des dosimètres individuels et des dosimètres de zone et détermination de leur réponse en fonction de l'énergie des particules bêta et de l'angle d'incidence du rayonnement bêta (ISO 6980-3:2023)
Le présent document décrit les modes opératoires pour l’étalonnage des dosimètres et des débitmètres de dose, et la détermination de leur réponse en termes de grandeurs opérationnelles utilisées à des fins de radioprotection et définies par la Commission internationale des unités et mesures radiologiques (ICRU, de l’anglais «International Commission on Radiation Units and Measurements»). Comme le souligne toutefois le rapport ICRU 56, l’équivalent de dose ambiant, H*(10), et l’équivalent de dose individuel, Hp(10), utilisés respectivement pour la surveillance de zone et pour la surveillance individuelle dans le cas de rayonnements fortement pénétrants ne sont pas des grandeurs appropriées pour un rayonnement bêta, même pour un rayonnement capable de traverser une épaisseur de tissu de 10 mm (Emax > 2 MeV).
Le présent document constitue un guide pour tout organisme procédant à l’étalonnage de dosimètres et de débitmètres de dose à des niveaux de dose de radioprotection en utilisant un rayonnement bêta de référence, et déterminant leur réponse en fonction de l’énergie des particules bêta et de l’angle d’incidence du rayonnement. Ces mesurages peuvent faire partie d’un essai de type au cours duquel les effets d’autres grandeurs d’influence sur la réponse sont examinés. Le présent document ne traite pas de l’étalonnage in situ des dosimètres de zone à poste fixe. Le terme «dosimètre» est un terme générique utilisé pour désigner tout dosimètre ou débitmètre de dose destiné à la surveillance individuelle ou de zone. Outre la description des modes opératoires d’étalonnage, le présent document comprend des recommandations pour les fantômes qu’il y a lieu d’utiliser et la méthode de détermination de coefficients de conversion appropriés. Des recommandations sont fournies concernant l’expression des incertitudes de mesure et la préparation des enregistrements et des certificats d’étalonnage.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
