Il est interdit d'utiliser un [appareil] d'exposition à moins [...] d'examiner, immédiatement avant d'utiliser [l'appareil] d'exposition, le mécanisme de verrouillage [de l'appareil] d'exposition, ainsi que le mécanisme à manivelle, le câble de commande, la pompe pneumatique, le mécanisme d'obturation, la fixation de [l'enveloppe] et le tube de guidage de la source, s'ils font partie intégrante [de l'appareil].

CONT

De nos jours, on utilise souvent les jauges fixes dans les usines de fabrication et de traitement pour assurer le contrôle de la qualité. Un faisceau de rayonnement est libéré en ouvrant l'obturateur, il passe ensuite à travers le matériau pour être mesuré par un détecteur monté à l'opposé de la source.
