For high activity smears Columbia does not put >50k cpm in our bench counter. We have a smear holder Ludlum 43-5 alpha scintillation detector and a Ludlum Model 3 with scaler feature to do timed smear counts and count the smears right at the location.

At Diablo, we are currently using the BC-4 and SAC-4. Monica Barnby ________________________________ PG&E is committed to protecting our customers' privacy.
