You’ll need a large voltage to get the Geiger tube to going - 325VDC minimum, 500VDC recommended. If ionizing radiation passes through the tube, short pulses of current will flow from the negative electrode to the positive electrode to be measured or counted. Check out the datasheet below for an application circuit.

Need to test for nuclear fallout? Geiger tubes are the sensing elements of Geiger counters, which are used to measure ionizing radiation. This tube is made of a thin-walled stainless steel and is filled with a mixture of Neon and Halogen gases at low-pressure.
This is the same tube used on our Geiger Counter development board.
