Measurement of radioactivity - Alpha-, beta- and photon emitting radionuclides - Reference measurement standard specifications for the calibration of surface contamination monitors (ISO 8769:2020)
This document specifies the characteristics of reference measurement standards of radioactive surface contamination, traceable to national measurement standards, for the calibration of surface contamination monitors. This document relates to alpha-emitters, beta-emitters, and photon emitters of maximum photon energy not greater than 1,5 MeV.
It does not describe the procedures involved in the use of these reference measurement standards for the calibration of surface contamination monitors. Such procedures are specified in IEC 60325[6], IEC 62363[7], and other documents.
NOTE Since some of the proposed photon standards include filters, the photon standards are to be regarded as reference measurement standards of photons of a particular energy range and not as reference measurement standards of a particular radionuclide. For example, a 241Am source with the recommended filtration does not emit from the surface the alpha particles or characteristic low-energy L X-ray photons associated with the decay of the nuclide. It is designed to be a reference measurement standard that emits photons with an average energy of approximately 60 keV.
This document also specifies preferred reference radiations for the calibration of surface contamination monitors. These reference radiations are realized in the form of adequately characterized large area sources specified, without exception, in terms of surface emission rate and activity which are traceable to national standards.
Bestimmung der Radioaktivität - Alpha-, Beta- und Photonenstrahlung emittierende Radionuklide - Spezifikation von Bezugsnormalen für die Kalibrierung von Oberflächenkontaminationsmonitoren (ISO 8769:2020)
Dieses Dokument legt, rückführbar auf nationale Messnormale, Eigenschaften von Bezugsnormalen für radio¬aktive Oberflächenkontamination zum Zweck der Kalibrierung von Oberflächenkontaminationsmonitoren fest. Dieses Dokument gilt für Alphastrahler, Betastrahler und Photonenstrahler mit maximalen Photonenenergien nicht größer als 1,5 MeV.
Es beschreibt nicht die Verfahren für die Anwendung dieser Bezugsnormale für die Kalibrierung von Oberflä¬chenkontaminationsmonitoren. Derartige Verfahren sind in IEC 60325 [6], IEC 62363 [7] und anderen Doku¬menten festgelegt.
ANMERKUNG Da einige der vorgeschlagenen Photonennormale Filter beinhalten, sind diese Normale als Bezugsnor¬male für Photonenstrahlung mit einem bestimmten Energiebereich anzusehen und nicht als Bezugsnormale eines bestimm¬ten Radionuklids. Zum Beispiel emittiert eine 241Am-Quelle mit der empfohlenen Filterung aus der Oberfläche weder die Alphateilchen noch die charakteristische, niederenergetische L-Schalen-Röntgenstrahlung, die mit dem Zerfall des Radio¬nuklids verbunden sind. Sie wurde entwickelt, um ein Bezugsnormal zu erhalten, das Photonen mit einer mittleren Energie von angenähert 60 keV emittiert.
Dieses Dokument legt auch die für die Kalibrierung von Oberflächenkontaminationsmonitoren bevorzugten Bezugsstrahlungen fest. Diese Bezugsstrahlungen sind als geeignet charakterisierte große Flächenquellen realisiert und werden ohne Ausnahme in Einheiten der Oberflächenemissionsrate und -aktivität angegeben, die auf nationale Normale rückführbar sind.
Mesurage de la radioactivité - Radionucléides émetteurs alpha, bêta et photoniques - Spécifications des étalons de référence pour l'étalonnage des contrôleurs de contamination de surface (ISO 8769:2020)
Le présent document spécifie les caractéristiques d'étalons de référence de contamination de surface radioactive, traçables par rapport à des étalons nationaux de mesurage, permettant l'étalonnage des contrôleurs de contamination de surface. Le présent document se rapporte aux émetteurs alpha, aux émetteurs bêta et aux émetteurs de photons dont l'énergie photonique maximale est inférieure ou égale à 1,5 MeV.
Il ne décrit pas les modes opératoires qu'implique l'utilisation de ces étalons de référence pour l'étalonnage des contrôleurs de contamination de surface. Ces modes opératoires sont spécifiés dans l'IEC 60325[6], l'IEC 62363[7] ainsi que dans d'autres documents.
NOTE Étant donné que certains des étalons photoniques proposés sont équipés de filtres, ces étalons sont destinés à être considérés comme des étalons de référence de photons d'une gamme d'énergie particulière, et non comme des étalons de référence d'un radionucléide particulier. Par exemple, un étalon de référence de 241Am muni du filtre recommandé n'émet pas, de la surface, les particules alpha ou les photons X de basse énergie, L, associés à la désintégration radioactive du radionucléide. Il est conçu pour être un étalon de référence émettant des photons ayant une énergie moyenne d'environ 60 keV.
Le présent document spécifie également des rayonnements de référence préférés pour l'étalonnage des contrôleurs de contamination de surface. Ces rayonnements de référence sont réalisés sous la forme d'étalons de référence de grande surface convenablement spécifiés et caractérisés, sans exception, en termes de taux d'émission surfaciques et activité traçables par rapport à des étalons nationaux.
Merjenje radioaktivnosti - Radionuklidi, ki oddajajo alfa in beta žarke ter fotone - Specifikacije referenčnega merilnega standarda za kalibracijo merilnikov površinske kontaminacije (ISO 8769:2020)
Ta dokument določa karakteristike referenčnih merilnih standardov radioaktivne površinske kontaminacije, izsledljive v nacionalnih merilnih standardih, za kalibracijo merilnikov površinske kontaminacije. Navezuje se na alfa in beta oddajnike ter fotonske oddajnike, katerih največja fotonska energija ne presega 1,5 MeV.
Ne opisuje postopkov v zvezi z uporabo teh referenčnih merilnih standardov za kalibracijo merilnikov površinske kontaminacije. Takšni postopki so določeni v standardih IEC 60325[6] in IEC 62363[7] ter drugih dokumentih.
OPOMBA: Nekateri od predlaganih fotonskih standardov vključujejo filtre, zato je treba fotonske standarde obravnavati kot referenčne merilne standarde fotonov z določenim razponom energije in ne kot referenčne merilne standarde določenega radionuklida. Vir Am-241 s priporočeno filtracijo na primer s površine ne oddaja alfa delcev ali značilnih nizkoenergijskih rentgenskih fotonov L, povezanih z razpadom nuklida. Zasnovan je kot referenčni merilni standard, ki oddaja fotone s povprečno energijo približno 60 keV.
Ta dokument določa tudi prednostno referenčno sevanje za kalibracijo merilnikov površinske kontaminacije. To referenčno sevanje se izvaja v obliki ustrezno opredeljenih velikih virov, ki so brez izjeme določeni z vidika stopnje površinskega sevanja in aktivnosti, izsledljivih v nacionalnih standardih.

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 documents 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).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
