You say the detector is designed to detect gamma rays, or any ionizing
radiation which is penetrating enough to enter the ionization chamber.
Was the intended use of the detector to measure radioactive fallout?
There were a large number of such detectors made and distributed to
public fallout shelters in the 1950s and 1960s.

Does the detector have a cumulative event counter which will work
unattended?

If so, perhaps if it were left running outdoors for a few hours, it would
detect cosmic rays, maybe something like one per hour.
