Non-destructive testing - Radiographic testing - Determination of the size of industrial radiographic gamma sources
This document specifies the determination of the size of gamma radiographic sources of 0,5 mm or greater, made from the radionuclides Iridium 192, Ytterbium 169, Selenium 75 or Cobalt 60, by a method of radiography with X-rays. The source size of a gamma radiography source is an important factor which affects the image quality of gamma ray images.
The source size is determined with an accuracy of ± 10 % but typically not better than ± 0,1 mm.
The source size is provided by the manufacturer as the mechanical dimension of the source insert. A measurement may be required if the manufacturing process is validated or monitored after implementation of the source into the holder.
This document can be used for other radionuclides after validation.
The standard test method ASTM E1114 provides further information on the measurement of the Ir-192 source size, the characterization of the source shape, and its correct assembly and packaging.
Zerstörungsfreie Prüfung - Durchstrahlungsprüfung - Bestimmung der Strahlergrößen von industriell genutzten Radio-Nukliden
Dieses Dokument legt die Bestimmung der Strahlergröße von Gammastrahlern von 0,5 mm oder größer der Radionuklide Iridium 192, Ytterbium 169, Selen 75 oder Cobalt 60 mit Hilfe eines Durchstrahlungs¬ver¬fahrens mit Röntgenstrahlen fest. Die Strahlergröße eines Gammastrahlers ist ein wesentlicher Parameter, der die Bildqualität von Durchstrahlungsbildern beeinflusst.
Die Strahlergröße wird mit einer Unsicherheit von ± 10 % bzw. höchstens ± 0,1 mm gemessen.
Die Strahlergröße wird vom Hersteller als mechanisches Maß des Strahlereinsatzes angegeben. Eine Messung kann erforderlich sein, wenn der Herstellungsprozess nach Befestigung des Strahlers im Halter überprüft oder überwacht wird.
Dieses Dokument kann auch für andere Radionuklide Anwendung finden, wenn die Machbarkeit überprüft wurde.
Das Standard Prüfverfahren ASTM E1114 enthält weitere Informationen zur Bestimmung der Strahlergröße des Radionuklids Ir 192, zur Charakterisierung der Form des Strahlers und zu seiner ordnungsgemäßen Montage und Verpackung.
Essais non destructifs - Contrôle radiographique - Détermination de la dimension des sources de radiographie industrielle gamma
Le présent document traite de la détermination, par une méthode de radiographie aux rayons X, des dimensions des sources de rayonnement gamma de 0,5 mm ou plus, fabriquées à partir des radionucléides iridium 192, ytterbium 169, sélénium 75 ou cobalt 60. La dimension d'une source de rayonnement gamma est un facteur important qui affecte la qualité des images obtenues par rayonnement gamma.
La dimension d'une source est déterminée avec une exactitude de ± 10 %, mais généralement de 0,1 mm au maximum.
La dimension de la source est fournie par le fabricant comme la dimension mécanique de la garniture de la source. Un mesurage peut être requis si le processus de fabrication est validé ou contrôlé après la mise en place de la source dans le porte‐source.
Le présent document peut être utilisé pour d'autres radionucléides après validation.
La méthode d'essai normalisée de l'ASTM E1114 fournit des informations supplémentaires sur le mesurage de la dimension de la source d'Ir‐192, la caractérisation de la forme de la source ainsi que des instructions pour la monter et l'emballer correctement.
Neporušitvene preiskave - Radiografsko preskušanje - Ugotavljanje velikosti industrijskih radiografskih gama izvorov
Ta dokument določa ugotavljanje velikosti radiografskih gama izvorov 0,5 mm ali večjih, izdelanih iz radionuklidov (iridija 192, iterbija 169, selena 75 ali kobalta 60) z metodo radiografije z rentgenskim sevanjem. Velikost radiografskega gama izvora je pomemben dejavnik, ki vpliva na kakovost gama slik.
Velikost izvora je ugotovljena z natančnostjo ±10 %, vendar običajno ne več kot ±0,1 mm.
Velikost izvora posreduje proizvajalec kot mehansko dimenzijo vstavka izvora. Če je proizvodni postopek potrjen ali nadzorovan po uvedbi izvora v držalo, je morda potrebno merjenje.
Ta dokument je mogoče uporabiti za druge radionuklide po potrjevanju.
Standardna preskusna metoda ASTM E 1114 podaja nadaljnje informacije o merjenju velikosti izvora Ir-192, opredelitev oblike izvora ter njegovo pravilno sestavljanje in pakiranje.

The article discusses the EN 12679:2018 standard, which determines the size of gamma radiographic sources used in non-destructive testing. The standard applies to sources made from specific radionuclides, such as Iridium 192 and Cobalt 60. The size of the source is important for the quality of gamma ray images. The document specifies that the source size can be determined with an accuracy of ± 10%, typically not better than ± 0.1 mm. The manufacturer provides the source size as the mechanical dimension of the source insert, but a measurement may be necessary if the manufacturing process is validated or monitored. The standard can also be used for other radionuclides after validation. The article also mentions that the ASTM E1114 standard provides additional information on measuring the size of an Ir-192 source, characterizing its shape, and proper assembly and packaging.
