[ RadSafe ] Cylinder Identity Question

[Geo>K0FF]

Scanning is a good idea since it was no doubt used in  a rad lab. Nuclear 
Counting Gas is a mixture of Methane and Argon and comes as P-10 or P-5 
usually. Non radioactive, but has a flammable constituent.
P-10 is what is used in "continuous flow gas proportional detectors", a kind 
of radiation sensor.

There are many other combinations of nuclear counting gas, but P-10 (90% Ar, 
10% CH4) is by far the most common today.

Other gasses might include CO2, Xe, CH4  (100% methane), C3H8 ( propane), 
isobutane, He.
