G-M counters having 20-mm diameter mica windows and graphite cathodes were constructed, filling them under a pressure of about 450 mm of mercury. The thickness of the windows was 6 mg/cm/sup 2/. The distance between the window and the glass sphere was kept at 2 to 3 mm. In vertical position the background level of the counters was below 100 cpm while their operating voltage was kept at 1300 to 1400 volts. (TTT)
