Subject: Powernet: Alpha Counting

Duke Energy request to following information:


What do you use to count smears for alpha/ beta activity?    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?
