Can anybody tell me about the failure modes of a (cheap Russian) Geiger
counter? Is leakage of the tube (i.e., continuous conduction rather than
waiting for ionizing particles) a common problem?

(This is not the popular Kvarts DRSB-01; it's a different one.)




Don't know about Russian ones but generally its due to failure of the bond
around the mica or whatever window on the end of the tube.
