RE: Uranium Release Limits

["Redmond, Randy R. (RXQ) " <RXQ@Y12.doe.gov>]

Unless you can demonstrate that alpha monitoring is an adequate surrogate to

show compliance with the beta limits, then you will need to monitor for

beta.  My opinion - beta would probably be a better surrogate to demonstrate

compliance with the alpha limits.
