We use them at Prairie Island. I have had good service from it. I do,
however see the P-10 gas dependency as a draw-back. The AP-2 (Eberline
?) is what I used for radon vs unat ratios back at the good old DOE
(Fernald). No P-10 needed, runs on one 9 volt battery, light hand-held

I was wondering if anyone out in the RadSafe world has ever had any
experience using a contamination monitor, model CM-11, made by Thermo
Fisher Scientific.  The CM-11 has a radon recognition feature, and I am
wondering how well it works, or if it works at all.  If anyone has used
one of these meters in the past I would really appreciate your input.  I
would like to know how easy or hard it is to use, and if it would be
practical to use in an outdoor environment for scanning out personnel.
Thanks in advance for any help!
