Introduction to Geiger Counters A Geiger counter (Geiger-Muller tube) is a device used for the detection and measurement of all types of radiation: alpha, beta and gamma radiation. Basically it consists of a pair of electrodes surrounded by a gas. The electrodes have a high voltage across them. The gas used is usually Helium or Argon. When radiatio created in air. In the geiger counter , which will be used as a detector in this experiment, the ionization produced by a charged particle causes a violent electrical discharge. Figure 3. The Geiger Counter. As shown in Figure 3, the counter consists of a meta l cylinder (cathode) with insulating ends supporting a fine axial wire (anode) on using the Geiger counter for our detection and experiments. Geiger counters are instruments that can detect and measure radioactivity using a Geiger Mueller tube. Geiger Mueller tubes are commonly referred to as a GM tube. The original design of the GM tube, created by Hans Geiger and E.W. Mueller in 1928, hasn't changed much, and the tube' the Geiger-Müller counter output count rate as a function of applied supply potential, V s.
