Rad Lab Issue

[hardtt@m4lp.com (Todd Hardt)]

     Is there any good, quantitative definition of a "Restricted Area"?   I 
     know the definition as stated in 10CFR20, but I want to know how to 
     determine if an analytical laboratory doing mixed waste analyses needs 
     to be restricted or should be a "controlled" area with access through 
     lock-and-key only.  I would appreciate responses from commercial mixed 
     waste laboratories, in-house plant laboratories and regulators.  We do 
     not nor will we ever handle the activity levels of a nuclear power 
     station.  Thank you.
