Radiation protection - Sealed sources - Leakage test methods (ISO 9978:2020)
This document specifies the different leakage test methods for sealed sources. It gives a comprehensive set of procedures using radioactive and non-radioactive means.
This document applies to the following situations:
— leakage testing of test sources following design classification testing in accordance with ISO 2919[1];
— production quality control testing of sealed sources;
— periodic inspections of the sealed sources performed at regular intervals, during the working life.
Annex A of this document gives guidance to the user in the choice of the most suitable method(s) according to situation and source type.
It is recognized that there can be circumstances where special tests, not described in this document, are required.
It is emphasized, however, that insofar as production, use, storage and transport of sealed radioactive sources are concerned, compliance with this document is no substitute for complying with the requirements of the relevant IAEA regulations[17] and other relevant national regulations. It is also recognized that countries can enact statutory regulations which specify exemptions for tests, according to sealed source type, design, working environment, and activity (e.g., for very low activity reference sources where the total activity is less than the leakage test limit).
Strahlenschutz - Umschlossene radioaktive Stoffe - Dichtheitsprüfungen (ISO 9978:2020)
Dieses Dokument beschreibt die verschiedenen Dichtheitsprüfverfahren für umschlossene radioaktive Stoffe. Es gibt eine umfangreiche Liste von Verfahren an, die sowohl mit als auch ohne Verwendung von radioakti¬ven Stoffen arbeiten.
Dieses Dokument gilt für die folgenden Situationen:
– Dichtheitsprüfung an Prüfstrahlern nach Baumusterprüfungen zur Klassifizierung nach ISO 2919 [1];
– Dichtheitsprüfung zur Qualitätssicherung bei der Herstellung von umschlossenen radioaktiven Stoffen;
– wiederkehrende Prüfungen der umschlossenen radioaktiven Stoffe, die in regelmäßigen Abständen wäh-rend ihrer Nutzungsdauer durchgeführt werden.
Anhang A dieses Dokuments gibt dem Anwender eine Orientierungshilfe bei der Auswahl des/r am besten geeigneten Verfahren(s), je nach Situation und Typ des Strahlers.
Unter bestimmten Umständen können Prüfungen erforderlich sein, die in diesem Dokument nicht beschriebe-nen sind.
Es wird jedoch darauf hingewiesen, dass die Anwendung dieses Dokuments in Bezug auf Herstellung, Ver-wendung, Lagerung und Transport von Strahlern die Erfüllung der Anforderungen der einschlägigen IAEA-Vorschriften [17] und anderer einschlägiger nationaler Vorschriften nicht ersetzt. Nationale Regelungen kön-nen erlassen werden, die Ausnahmen für Prüfungen in Abhängigkeit von der Art der umschlossenen radioak-tiven Stoffe, ihrer Konstruktion, der Arbeitsumgebung und der Aktivität festlegen (z. B. für Referenzquellen mit sehr geringer Aktivität, bei denen die Gesamtaktivität unter dem Grenzwert für die Dichtheitsprüfung liegt).
Radioprotection - Sources scellées - Méthodes d’essai d’étanchéité (ISO 9978:2020)
Le présent document spécifie les différentes méthodes d'essai d'étanchéité pour les sources scellées. Il propose un ensemble complet de modes opératoires utilisant des moyens radioactifs et non radioactifs.
Le présent document s'applique aux situations suivantes:
— essais d'étanchéité de sources d'essai suivant les essais de classification théorique selon l'ISO 2919[1];
— essais de contrôle de la qualité de production de sources scellées;
— contrôles périodiques des sources scellées effectués à intervalles réguliers pendant la durée de vie en service.
L'Annexe A du présent document donne des recommandations à l'utilisateur dans le choix de la ou des méthodes les plus appropriées en fonction de la situation et du type de source.
Il est admis que, dans certaines circonstances, des essais spéciaux non décrits dans le présent document sont nécessaires.
Il faut souligner cependant que, dans la mesure où la production, l'utilisation, le stockage et le transport des sources radioactives scellées sont concernés, la conformité au présent document ne peut se substituer aux exigences des règlementations de l'AIEA[17] et d'autres règlementations nationales pertinentes. Il est reconnu également que les pays peuvent édicter des règlementations qui spécifient des exemptions aux essais, en fonction du type de source scellée, de la conception, de l'environnement de travail et de l'activité (par exemple, pour les sources étalons de très faible activité dont l'activité totale est inférieure à la limite de l'essai d'étanchéité).
Zaščita pred sevanjem - Zaprti viri - Metode preskušanja prepuščanja (ISO 9978:2020)
Ta dokument določa različne metode preskušanja prepuščanja za zaprte vire. Zagotavlja celovit niz postopkov z uporabo radioaktivnih in neradioaktivnih sredstev.
Ta dokument se uporablja za naslednje primere:
– preskušanje prepuščanja preskusnih virov po preskusu klasifikacije zasnove v skladu s standardom ISO 2919[1];
– preskušanje nadzora kakovosti proizvodnje zaprtih virov;
– periodično pregledovanje zaprtih virov v rednih časovnih intervalih med življenjsko dobo.
V dodatku A tega dokumenta so podane smernice uporabnikom za izbiro najustreznejše metode oziroma metod glede na posamezen primer in vrsto vira.
Ugotovljeno je, da so lahko v določenih okoliščinah potrebni posebni preskusi, ki niso opisani v tem dokumentu.
Ob tem je treba poudariti, da skladnost s tem dokumentom v zvezi s proizvodnjo, uporabo, skladiščenjem in prevozom zaprtih radioaktivnih virov ne nadomešča izpolnjevanja zahtev ustreznih predpisov Mednarodne agencija za atomsko energijo (IAEA)[17] in drugih ustreznih nacionalnih predpisov. Ugotovljeno je tudi, da lahko države sprejmejo zakonske predpise, ki določajo izjeme za preskuse glede na vrsto zaprtega vira, zasnovo, delovno okolje in aktivnost (npr. za referenčne vire z zelo nizko aktivnostjo, pri katerih je skupna aktivnost manjša od meje preskusa prepuščanja).
