Re: [Powernet] Alpha Determination

We would use an alpha frisker if greater than 100k dpm beta. However, our "high contamination" is about 20 mrad/hr rather than 15 R/hr. Although EPRI would specify alpha counts in this situation, I think you've identified what your real radiological risk would be for this work. Hopefully, you
