most halide bulbs are far from a vacuum (some carrier gas in there), 
so xrays aren't likely.  But testing IS a good idea.

The peak potentials are high enough to produce X-rays. It really
depends on the exact vacuum in the tube.

I would try to befriend some local radiologist and see if he would
lend you a badge.  Expose it for 10-20 sec (with you at a great
distance) and then have the radiologist process the safety
badge.  This is the best way --- no since taking any chances.

I definitely not hold it until you get a badge processed.
