LEAK TESTING 

 

 

SECTION 3: LEAK TESTING 

Periodic leak testing of the radioactive sources used in the storage container are required by most 

national and international regulations. The leak test provides a confirmation of the integrity of the 

hermetically welded sealed source by determining the amount of removable contamination. In most 

regulatory jurisdictions, a leak test of a sealed source must be performed 

every 6 months

 or prior to its 

first use after removal from storage. Acceptable results of a radio-assay must indicate removable 

contamination in less than <185 Bq (0.005 µCi). 

Evaluation of depleted sources for return to QSA Global, Inc. should be leak tested while still contained 

in their exposure device in accordance with the applicable device procedures. This test must be 

performed in a properly secured Controlled Area. The individual performing this test should wear a 

direct reading pocket dosimeter and either a film badge or thermoluminescent dosimeter. The individual 

should also use a properly calibrated and operable radiation survey instrument.
