Leak Testing Sealed Sources

[HALEEM MAHMOUD SAID <mshaleem@dpc.kfupm.edu.sa>]

I am having troubles convincing people here regarding the leak testing of 
sealed sources.  AT our university we have smalled sealed sources of 
alpha and gamma.  The activities range from few microcuries down to 
submicrocuries.  Most of the sources are rarely used.  I need your 
cllective efforts in helping me in pointing out what are the trigger 
levels for leak testing of sealed radioactive sources.

YOUR input is much appreciated. Thanks
