What happens in a Geiger-Müller tube when there is no voltage?
What happens in a Geiger-Müller tube when it is not connected to a circuit?
Ionizing radiation must still be creating ions inside it, but they cannot move to the anode because there is no potential ...

Can leaving a Geiger–Müller tube energized continuously cause it to wear out?
I recently acquired a Geiger counter to feed my raging paranoia curiosity.
However, I am wondering if it could harm the Geiger–Müller tube to leave it energized continuously?
I know a couple places (...
