Looking for portable source-check holder

[Glen.Vickers@ucm.com]

I am looking for a portable beta source-check holder which might hold 5 disk
sources.  I could imagine a plexiglass bar approximately 7 or 8 inches long
with Tc-99 sources in a line.  The 5 sources would permit me to check 5
different scales.  I could possibly imagine a single source and rotating
filter, but I'm not sure that would be too durable.  

I'm looking to 10 to 12 commercially available units within the next 60 days
if possible.  These would be carried by personnel performing source checks
on "rounds".

I am also looking for a small source check table for source checking all the
ranges on a micro-rem meter.  Range of operation is 0 uR to 200 mrem/hr with
5 scales.  Probable source would be Cs-137.  This unit would be stationery
and reside in the calibration facility

Such a units should be relatively easy to make; however, our shop is too
busy at this time and I need to move forward with program improvements.

Any good experiences out there?

Sincerely,
Glen Vickers
