摘要：	Recent radioactive packagings with three-O-ring closure seals, the middle O-ring being the containment seal, have the potential for false positive results from leakage rate tests. The volume between tile containment O-ring and the inner O-ring is used for the helium gas required for the leakage rate tests, to reduce both the amount of helium used and the time for the tests. False positive results can be caused by either a large leakage in the containment seal or a leakage in the inner seal. This paper describes the problem, together with possible solutions/areas that need to be addressed in a Safety Analysis Report for Packaging.
