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.

Introduction
ISO 6980 series covers the production, calibration, and use of beta-particle reference radiation fields
for the calibration of dosemeters and dose-rate meters for protection purposes. This document
describes procedures for the calibration of dosemeters and dose-rate meters and the determination
of their response as a function of beta-particle energy and angle of beta-particle incidence. ISO 6980-1
describes the methods of production and characterization of the reference radiation. ISO 6980-2
describes procedures for the determination of absorbed dose rate at a reference depth of tissue from
beta particle reference radiation fields.
For beta particles, the calibration and the determination of the response of dosemeters and dose-rate
meters is essentially a three-step process. First, the basic field quantity, absorbed dose to tissue at
a depth of 0,07 mm (and optionally also at a depth of 3 mm) in a tissue-equivalent slab geometry is
measured at the point of test, using methods described in ISO 6980-2. Then, the appropriate operational
quantity is derived by the application of a conversion coefficient that relates the quantity measured
(reference absorbed dose) to the selected operational quantity for the selected irradiation geometry.
Finally, the reference point of the device under test is placed at the point of test for the calibration
and determination of the response of the dosemeter. Depending on the type of dosemeter under test,
the irradiation is either carried out on a phantom or free-in-air for personal and area dosemeters,
respectively. For individual and area monitoring, this document describes the methods and the
conversion coefficients to be used for the determination of the response of dosemeters and dose-rate
meters in terms of the ICRU operational quantities, i.e., directional dose equivalent, H′(0,07;Ω) and
H′(3;Ω), as well as personal dose equivalent, H (0,07) and H (3).
