You are right. No vacuum, no xrays. (Yes, you can make xrays with a
sufficiently fast rise time pulse, but TC's are many,many orders of
magnitude too low (you need something like 1e9 amp/uSec))
UV is somewhat of a hazard, although the current in the spark is pretty
low, compared to notable eye hazards like a welder. TC sparks just
aren't all that bright. I wouldn't stare at the spark gap (and would
shield it for convenience, as well).
Based on my own experience with HV spark producing devices, I think that
loud noise is probably your biggest hazard. It is insidious (you don't
know you are going deaf as it happens). Those sparks are really loud,
and impulsive to boot, which means that they don't register on a cheap
sound level (e.g. Radio Shack) as high as they should.
