Counting Wet Smears

[ml_johnson@ccmail.pnl.gov]

     I am looking for information on methods to count wet smears.  Much of 
     the work performed at Hanford is out-of-doors and can't necessarily 
     stop just because of a little rain or dew.  Currently, smears are 
     dried before counting.  However, if there is a justifiable technique 
     for counting a wet smear, I would like to hear about it.
     
     In addition, are there any definitions of "how wet is wet"?  At what 
     point is a smear considered a wet smear?
     
     The isotopes of concern are Co-60, Eu-152, and Cs-137.  The smear 
     media is masslin and cloth technical smears.
