    Abstract: A gas-filled ionization counter in which the cathode and anode are placed in an envelope filled with a gaseous mixture and form the main gas-discharge gap and which has a performance check facility. The said facility compris electrodes placed in the gaseous mixture of the envelope and forming an auxiliary gap, and a radio-active source of specified activity, placed in the auxiliary gap so that its own radiation induces a gas discharge solely in the auxiliary gap. All this provided a check on the stability of the counter''s characteristics in service.
