[ RadSafe ] Looking for information on Alphatron Pressure Gauge

[Wasiolek, Maryla]

Dear RadSafers,

I am looking for information on the old National Research Corporation Alphatron Gauge.  We are planning on disposing it off through the OSRP and have to extract the source from the gauge to fit the OSRP capsule, whose ID is about 2 in.  I was wondering is anybody could recognize the instrument from the attached pictures (see the link below) and perhaps knows where the source is located.  The gauge is supposed to contain 0.5 Ci of Ra-226.  Any information regarding this instrument would be appreciated.
