Geiger-Muller tube. Experiment with a radioactive source (lower left),a Geiger-Muller tube (lower right) and a ratemeter (centre). A Geiger-Muller tube is used to detect levels of of radiation. Radiation passing through gas in the tube ionises it,briefly allowing a current to flow. This electrical pulse is recorded,with radioactive intensity proportional to the number of pulses in a given time period. It can detect alpha,beta and gamma radiation | |
