Air is perfectly fine. Both Oxygen and Nitrogen do not stay radioactive for longer than a few seconds. It's CO2 that is the problem, specifically the carbon.
And of course any other random impurity.
They could just use cryogenicaly distilled air, and take the nitrogen-oxygen part (the boiling points are very close).
