DEF

A form of leak test in which the interior of an enclosure is actively evacuated while a tracer gas is applied to the exterior. The objective is to draw in some of the gas through possible leakage paths so that its presence becomes evident to a leak detector which will respond to the type of the type of gas used and which is connected in the evacuating system.

DEF

Facsimile of a radioactive sealed source the capsule of which has the same construction and is made with exactly the same materials as those of the sealed source that it represents but containing, in place of the radioactive material, a substance with mechanical, physical and chemical properties as close as possible to those of the radioactive material and containing radioactive material of tracer quantity only. The tracer is in a form soluble in a solvent which does not attack the capsule and has the maximum activity compatible with its use in a glove box. [Definition standardized by ISO. ]

DEF

Source radioactive factice fabriquée dans le même matériau et construite de la même manière qu'une source radioactive, mais renfermant à la place de la matière radioactive, une matière dont les propriétés mécaniques, physiques et chimiques sont aussi proches que possible de celles de la matière radioactive et ne contenant que des traces de la matière radioactive. Ces traces sont sous forme soluble dans un solvant qui n'attaque pas l'enveloppe et qui a une activité maximale compatible avec son utilisation dans une boîte à gants. [Définition normalisée par l'ISO.]
