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.
