re: QC for well counters

[kendoug@wvnvm.wvnet.edu (Ken Douglass)]

10CFR35.70 says wipe tests to detect removable contamination should be able
to detect 2000 dpm. I would like to know if anyone specifically tests their
well counter for this sensitivity, eg by creating a Tc-99m spot of known
activity, then allowing it to decay, then swiping it.
