Just bought a PDR-27R radiac, bought 6 D cells too.
Found all the 'special' meters. One was in the R-392.
Typical emission (beta window shut) at the glass surface was
about 0.01 to 0.02 mR/Hr, just barely above background as shown
on meter.
Background was average of about 1 tick per second, over a period
of about 15 seconds. The reading from the R-392's meter was about
17 ticks in 10 seconds.
Caveat, unit is not calibrated.. need to send it to KI4U for cal.

Cool.

The problem with the radium is that if it's leaking out (ie flaking off) it's going to give off various forms of low and high energy radiation. If you get bits of this in your system then those bits will bombard your surrounding tissue with radiation as they decay.

Minimize the exposure to the dust. The problem with this warehouse is probably that the amount of flaking dust makes the concentration so high that it is in fact dangerous. If it was just a few carefully stored gauges each in a bag, then it probably wouldn't be such a problem. But there's probably so much bits of radium in flaking paint on the floor and in the air that it is a hazard to someone going into the room.
