3.8 microrem per hr - mea culpa

[GEORGE CICOTTE <GEORGE_CICOTTE@health.ohio.gov>]

     Yeah, Wes, I was going on intuition on that one.  I should have run a 
     calculator on that.  Most direct photon measurements I've seen, 
     however, are on the order of 0.1 microsieverts per hour, and since so 
     much of the 4 microsieverts is from Radon lung dose, I still think the 
     time integral of the scan versus the per-hour environmental 
     measurement would hold up.  I didn't see anything about the duration 
     of the scan, but one would infer a short duration in order to make it 
     practical.
     
     The "60 feet distance" is potentially scary, given the possible 
     surface rate.  I'm sure this isn't neutrinos.  I hadn't seen that when 
     I scanned it the first time.
