Re: metal halide bulbs and Tesla coils

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.

While scrounging through my favorite sign company's scrapyard, I ran across an old parking lot lamp fixture sporting a metal halide bulb, 15" long and 7" in diameter. It's a "<http://beverlyhillselectric.stores.yahoo.net/sylm1000ubt37.html>Syvania M1000/U/BT37 Comnpact Metalacr 1000 watt reduced outer jacket metal halide lamp, clear" (http://beverlyhillselectric.stores.yahoo.net/sylm1000ubt37.html). I have seen some cool effects using large bulbs in concert with Tesla coils. However, I am concerned about x-ray emissions after reading about "bremsstrahlung radiation". Do I dare not connect this lamp to the toroid of my 4" coil? Do I dare not hold this lamp in my hand in close proximity to my operating coil? I'm looking forward to some interesting feedback.
