[ RadSafe ] Matching Backgrounds for Gamma Count Rates

[Cehn at aol.com]

For building or lab closure surveys, I rarely have pre-op gamma count rate  
measurements for comparison.  To try and find a "matching" location to  obtain 
gamma backgrounds is next to impossible.  As previously discussed  here, gamma 
count rates vary widely.  I would be interested in hearing how  others have 
handled this problem.
