Radiological protection - Criteria and performance limits for the periodic evaluation of dosimetry services for external radiation (ISO 14146:2024)

The quality of a supplier of a dosimetry service depends on both the characteristics of the approved (type‑tested) dosimetry system[1] and the training and experience of the staff, together with the calibration procedures and quality assurance programmes.
This document specifies the criteria and the test procedures to be used for the periodic verification of the performance of dosimetry services supplying personal and/or area dosemeters.
An area dosemeter can be a workplace dosemeter or an environmental dosemeter.
The performance evaluation can be carried out as a part of the approval procedure for a dosimetry system or as an independent check to verify that a dosimetry service fulfils specified national or international type test performance requirements under representative exposure conditions that are expected or mimic workplace fields from the radiological activities being monitored.
This document applies to personal and area dosemeters for the assessment of external photon radiation with a (fluence weighted) mean energy between 8 keV and 10 MeV, beta radiation with a (fluence weighted) mean energy between 60 keV and 1,2 MeV, and neutron radiation with a (fluence weighted) mean energy between 25,3 meV (i.e. thermal neutrons with a Maxwellian energy distribution with kT = 25,3 meV) and 200 MeV.
It covers all types of personal and area dosemeters needing laboratory processing (e.g. thermoluminescent, optically stimulated luminescence, radiophotoluminescent, track detectors or photographic-film dosemeters) and involving continuous measurements or measurements repeated regularly at fixed time intervals (e.g. several weeks, one month).
Active dosemeters (for dose measurement) may also be treated according to this document. Then, they should be treated as if they were passive (i.e. the dosimetry service reads their indicated values and reports them to the evaluation organization).
[1] If this document is applied to a dosimetry system for which no approval (pattern or type test) has been provided, then in the following text approval or type test should be read as the technical data sheet provided by the manufacturer or as the data sheet required by the regulatory authority.

Strahlenschutz - Kriterien und Mindestanforderungen bei der wiederkehrenden Überprüfung von Dosismessstellen (ISO 14146:2024)

Radioprotection - Critères et limites de performance pour l'évaluation périodique des services de dosimétrie (ISO 14146:2024)

La qualité d'un prestataire de services de dosimétrie dépend à la fois des caractéristiques du système[1] de dosimétrie homologué (ayant été soumis à un essai de type) et de la formation et de l'expérience du personnel, ainsi que des procédures d'étalonnage et des programmes d'assurance qualité.
Le présent document spécifie les critères et les modes opératoires d'essai à utiliser pour procéder à la vérification périodique de la performance des services de dosimétrie fournissant des dosimètres individuels et/ou des dosimètres de zone.
Un dosimètre de zone peut par exemple être un dosimètre sur poste de travail ou un dosimètre d'environnement.
L'évaluation de performance peut soit faire partie de la procédure d'homologation d'un système de dosimétrie, soit consister en un contrôle indépendant visant à s'assurer qu'un service de dosimétrie satisfait aux exigences de performance liées à un essai de type, spécifiées dans une norme nationale ou internationale, dans des conditions d'exposition représentatives qui correspondent à celles attendues ou simulent les champs de postes de travail des activités radiologiques faisant l'objet d'un suivi dosimétrique.
Le présent document s'applique aux dosimètres individuels et aux dosimètres de zone utilisés pour l'estimation des rayonnements suivants: rayonnement photonique externe d'une énergie moyenne (pondérée par la fluence) comprise entre 8 keV et 10 MeV, rayonnement bêta d'une énergie moyenne (pondérée par la fluence) comprise entre 60 keV et 1,2 MeV et rayonnement neutronique d'une énergie moyenne (pondérée par la fluence) comprise entre 25,3 meV (c'est-à-dire des neutrons thermiques présentant une distribution énergétique maxwellienne avec kT = 25,3 meV) et 200 MeV.
Il couvre tous les types de dosimètres individuels ou de zone nécessitant un traitement en laboratoire (par exemple, dosimètres thermoluminescents, à luminescence stimulée optiquement, radiophotoluminescents, détecteurs de traces ou à films photographiques) utilisés pour réaliser des mesurages continus ou répétés à intervalles réguliers (par exemple, de plusieurs semaines ou d'un mois).
Les dosimètres actifs (pour le mesurage de la dose) peuvent également être traités selon le présent document. Dans ce cas, il convient de les considérer comme des dosimètres passifs (c'est-à-dire que le service de dosimétrie relève les valeurs affichées et les communique à l'organisme d'évaluation).
[1] Si le présent document devait être appliqué à un système de dosimétrie n?ayant reçu aucun agrément (séquence d?essais ou essai de type), alors, dans la suite du texte, il convient que l?homologation ou l?essai de type soient compris comme étant la fiche technique établie par le fabricant ou exigée par les autorités réglementaires.

Radiološka zaščita - Merila in meje učinkovitosti za periodično ovrednotenje dozimetričnih storitev za zunanje sevanje (ISO 14146:2024)

Kakovost ponudnika dozimetrične storitve je odvisna tako od značilnosti odobrenega (tipsko preskušenega) dozimetričnega sistema[1] kot tudi od usposobljenosti in izkušenj osebja, skupaj s postopki umerjanja in programi za zagotavljanje kakovosti.
Ta dokument določa merila in preskusne postopke za periodično preverjanje učinkovitosti dozimetričnih storitev, pri katerih se uporabljajo osebni in/ali območni dozimetri.
Območni dozimeter je lahko dozimeter na delovnem mestu ali okoljski dozimeter.
Ovrednotenje učinkovitosti je mogoče izvesti kot del postopka odobritve za dozimetrični sistem ali kot neodvisno preverjanje, s katerim se ugotavlja, ali dozimetrična storitev izpolnjuje določene nacionalne ali mednarodne zahteve glede delovanja za tipske preskuse v reprezentativnih pogojih izpostavljenosti, ki se pričakujejo ali simulirajo polja, ki jih oddaja radiološka dejavnost na delovnem mestu, ki se spremlja.
Ta dokument se uporablja za osebne in območne dozimetre za ocenjevanje zunanjega fotonskega sevanja s (fluenčno uteženo) srednjo energijo med 8 keV in 10 MeV, beta sevanja s (fluenčno uteženo) srednjo energijo med 60 keV in 1,2 MeV ter nevtronskega sevanja s (fluenčno uteženo) srednjo energijo med 25,3 meV (tj. toplotni nevtroni z Maxwellovo porazdelitvijo energije s kT = 25,3 meV) in 200 MeV.
Zajema vse vrste osebnih in območnih dozimetrov, ki potrebujejo laboratorijsko obdelavo (npr. termoluminiscenčno, optično stimulirano luminiscenčno, radiofotoluminiscenčno, detektorje sledi ali dozimetre s fotografskim filmom) in vključujejo stalne meritve ali meritve, ki se redno ponavljajo v določenih časovnih intervalih (npr. več tednov, en mesec).
Aktivni dozimetri (za merjenje doze) se prav tako lahko obravnavajo v skladu s tem dokumentom. Zatem jih je priporočljivo obravnavati kot pasivne (tj. dozimetrična storitev odčita njihove vrednosti in jih sporoči organizaciji, ki izvaja vrednotenje).
[1] Če se ta dokument uporablja za dozimetrični sistem, za katerega ni bila podana odobritev (preskus vzorca ali tipski preskus), naj se v naslednjem besedilu odobritev oziroma tipski preskus bere kot tehnični list, ki ga zagotovi proizvajalec, ali kot podatkovni list, ki ga zahteva regulativni organ.

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
