Cook Plant uses a Ludlum 3030P or a Canberra S5E. Contamination limit is 250,000 dpm. Ideally, if higher contamination, we would get a lower activity smear. We have also cut the smear and taken a smear of a smear.

Canberra iSolo, Ludlum 3030P, other? Do you have a limit on the activity (dpm) that can be counted using a smear counter? And if you have a limit on activity, what is the limit and how do you count smears above the activity limit (beta) for alpha?
