Summary: | In this paper, the aging effect of commercially available Geiger-Muller
counters under working conditions is being considered from both theoretical
and experimental point of view. In the experimental part lifetime curves for
the commercial Geiger-Muller counter chamber are first recorded. After
detection of the aging phenomena, the commercial chamber response to an
impulse voltage is tested along with recording of the same response of the
Geiger-Muller chamber model with conductive particles included. The law of
similarity for the gaseous discharge is fulfilled both by the commercial
Geiger-Muller chamber and by the chamber model with conductive particles. The
results obtained from the U-test indicate that the aging of the Geiger-Muller
chamber is mainly caused by the occurrence of a great number of conductive
particles hovering inside the chamber. Some suggestions of how to reduce the
aging effect due to conductive particles inside the Geiger-Muller chamber are
given in the conclusion. [Project of the Serbian Ministry of Education,
