1 Scope
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
