Counter for detecting the intensity of ionizing radiation (beta particles, gamma rays and x-rays). Use a gas tube, Every time the ray ionizes in the Geiger-Miller tube to produce a pair of ions, an electrical pulse of the same size can be amplified and recorded by the connected electronic device, so that the number of rays per unit time can be measured. It mainly used to detect nuclear power plants, industrial mines, seafood, cosmetics, marble, medical X-ray and other radiation environment.
