If a xenon flash tube has say 300V across it, what is the chance that it can trigger by atmospheric radiation alone, (ie without needing a trigger pulse)?

The one big difference between a flash tube and a geiger tube is the electrode geometry.The whole thing is basically a poor-boy Geiger
counter, only lacking the actual counter, and not
at all optimized for sensitivity. The low density of
material makes it reasonably likely that even if an
ionizing particle or energetic-enough photon did
traverse the lamp volume, it would not interact.
Energy dropped by an ion track is proportional to
material density.
