I played around with my geiger counter an find it making beeps near my plasma bulb.
It also making beep on a electric train then there are sparks at the connecting on the roof. I have heard that the geiger tubes is sensitive for electrical fields. But if the voltage is high enough a discharge can make X-rays.

I have a conventional geiger counter and I find it beeps if it is within 5cm of the high voltage output. The distance suggests alpha particles, but a peice of card makes no difference so I assume that this is an artefact picked up by the large and abrupt change in the voltage gradient. Oddly I could not find any reference to this artefact on the internet. Is this just something that everyone knows but no-one writes down?
