10.2 Leak Test
Depending on the regulatory authority of the country in which the
source is being used, recurrent leak tests, so-called wipe tests,
have to be carried out.
10.2.1 Leak Test Documentation
Inventory listings of the source to be tested with information
on the leak tests carried out in the past.
Source certificate stating the following information:
Nuclide, activity, procurement date, physical-chemical form
Description of encasement and type of sealing
Resistance to mechanical and thermal effects or classification of
the source construction type
Information on location, application purpose and the customary
maximum mechanical and thermal stress.
Is the source is installed in a device, a drawing has to be enclosed
which clearly states the position of the source and all parts serving
as protection against external influences. Proposals for the best
test method should be provided, e.g. through information on alter-
native test areas and, if necessary, the required manipulations, i.e.
how the test can be carried out without any adverse effect on the
operatability of the facility or device.
Certificate on acceptance inspection by the manufacturer.
