In the newly developed indicator, a thyratron (with cold cathode) is used in combination with a Geiger counter. The Gelger counter is used in the range of the "middle current." The control grid of the thyratron working without a heater current is connected to the R-C member to be integrated. If no gamma radiation impinges upon the counting tube, there will be no current in the load resistance. If, however, the counting tube is irradiated, the middle current in the load chain increases, and, accordingly, the potential at the control electrode and the current in the control circuit are likewise increased. If the current in the control circuit attains the amount of the extinguishing voltage of the thyratron, there is no more ignition, and the current flows in the anode- cathode circuit. The relay connected in this circuit begins to operate. This apparatus was produced in the laboratory and the necessary technical data are given. With a pulse number of 150 to 200 pulses per second at the Geiger counter the apparatus operated satisfactorily. The dependence between the activity of the source A in mc and the distance R between the source and the counting tube can be expressed by the formula: A = 3R/sup 2/. (TCO)
