  1. Geiger counter A Geiger–Müller counter, also called a Geiger counter, is a type of particle detector that measures ionizing radiation,Fig1. It detects the emission of nuclear radiation: alpha particles, beta particles or gamma rays by the ionization produced in a low-pressure gas in a Geiger–Müller tube, which gives its name to the instrument.
