Abstract
Spurious random pulses were found which are independent of external radiation, depending exponentially on the voltage above the threshold of sensitivity of the counter and on the reciprocal value of the absolute temperature. It is shown that the assumption of chemical reactions taking place on the surface of the cathode theoretically leads to an identical dependence on the temperature. By calculation one can find the numerical values of the activating energies of chemical reactions or the work function of the metals of the cathode materials. The question of dependence of the number of spurious pulses on the threshold voltage of the counter has been left open for the time being.
