Do you have a limit on the activity (dpm) that can be counted using a smear counter? 250,000 dpm 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? Direct measurement with an ion-chamber, take a smaller sample & apply a scaling factor David Brehm Fort Calhoun Nuclear Station Office: 402.533.7582 Cellular: 402.214.0107 Pager: 402.561.3310 From: [email protected] [mailto:[email protected]] On Behalf Of Byrum, William F Sent: Monday, August 27, 2012 7:46 AM To: [email protected] Subject: Powernet: Alpha Counting Duke Energy request to following information: What do you use to count smears for alpha/ beta activity?
