We use a gas-proportional counter. Efficiency based on a plated Ni-63 source.
A liquid scintillation counter would be better, but we've not (yet) set up a
counting protocol & process for the one that Chemistry has.

Subject: Powernet: Leak testing Ni-63 Sources
Duke Energy would like to know what process other sites use for leak testing
Ni-63 sources. Specifically, what type of smear and what method used to count
the smear.
Thank you,
Graham Johnson
