Geiger Miller counter

Geiger Miller counter

The Geiger M ü ller counter, also known as the Geiger counter, is a counting instrument specifically designed to detect the intensity of ionizing radiation (alpha particles, beta particles, gamma rays, and X-rays). Using an inflatable tube or chamber as a probe, when the voltage applied to the probe reaches a certain range, each pair of ions produced by ionization of the radiation inside the tube can amplify and generate an electric pulse of the same size, which is recorded by the connected electronic device, and thus measure the number of rays per unit time.
