ABSTRACT:
A process for testing leaks of a package (20) comprises the steps of introducing the package (20) into a chamber (30) and pressurizing the chamber (30) with a radioisotopic gas (14). After the package (20) has been removed from the chamber (30), a plurality of detectors (46) sense the gamma-ray emission from the individual packages (29). A conveyor system (44) can be employed to move the packages (20) during high volume production.
