An investigation was made of the possibility of detecting fast neutrons with the aid of spark counters. Two tynes of counters were used: with filament- like anode and plane (or half-cylindrican cathode and with plane cathodes and an anode made of parallel wires. The cathode was made of pclished brass, the anodes of tungsten wire 0.1 mm in diameter. The counters were filled with air, nitrogen, and hydrogen. When the counters were filled with air, because of prcduction of ozone, oxidation of the electrodes was noticed and a change was seen in the operating characteristics of the counters with time. All the counters had a voltage plateau approximately 400 volts long. The efficiency to fast neutrons for a counter with three filaments, filled with nitrogen, hydrogen, and air, is 10/sup -3/, 6 x 10/sup -4/, and 10/sup -4/%, respectively. The counter is practically insensitive to gamma rays.
