Re: Acceptable P-32 monitoring methods

I can't imagine using LSC wipes in place of a GM for P-32 
contamination.  While LSC can count P-32 samples, it is not very 
useful for performing surveys (as Sue's example points out).  

Not only is the GM the ideal detector (but stay away from side window 
probes), it is much cheaper, cleaner and faster than LSC.  If there 
is only a little use of P-32, remember that GMs can come in very 
small and cheap sizes.
