Re: tritium removable contamination

[Bob Wilson <bmwils2@pop.uky.edu>]

Bill,

After many years of effort, I have to accept that a standard wipe (as used
for anything else) is about as good as we can get.  We use dry filter paper
wipes.  Multiply the LSC CPM by 4 or 5 or 10 or whatever makes one feel
comfortable to get activity.

I sure do miss those peanuts, though!
