Abstract
The design problems for Geiger counters which have a high gamma-radiation sensitivity are discussed. A description of a Geiger counter consisting of nine individual counters in the shape of pillboxes mounted inside a single envelope is given. The individual pillboxes are 3 inches in diameter. The anode has the shape of a four-pronged spider which is centered in the box. The nine section counter has a flat plateau of about 150 volts, and intrinsic sensitivity of 25 percent. Its lifetime is better than 107 counts.
