        Geo,
         
        Regarding the discussion of neon lamps and voltage regulator tubes as radiation detectors, here is what I got from Allyn Goshy about the regulator tube in the Geiger/Radio used as a GM tube.

        Doug,

        I have never been able to get a neon to detect radiation either.

        The Regulator tube that I talked about is a #445. That is the only ID
        on the tube, no manufacturer. It operates on 300 volts.

        ---------------------------

         
        The internal construction at the end where the leads emerge is very similar to the 5841 "Corotron" regulator made by Victoreen. On some of the 5841's I also find the number 504. If someone has an old Victoreen catalog, the #445 might be listed.
