RE: Looking for a very high count rate alpha meter

["Richards, David" <david.richards@rfets.gov>]

That's correct. It is an actual RO-2 and it is yellow. I'm not sure if it
was a special build for them or if it is a normal production piece. We used
them when I was at the burial ground a couple years back. They had PAC-4s
that, if I remember correctly, went to 2 million CPM and the RO-2s for high
range that went to 4 million CPM. An interesting trivia note is their unique
terminology for anything high enough to peg the RO-2. If the RO-2 went
offscale, the reading was recorded as "UTM" which stands for "Un-told
Millions".

Anyway, the guy that used to be in charge of their instrument lab was Bill
Wilke. The last number I had for him is 803-725-3720 but that's pretty old.
It's worth a shot, though.
