Geiger-Muller tube. Illustration of a Geiger-Muller tube (blue) measuring radiation from a Am-241 (americium-241) alpha radiation source (far left), with a ratemeter (bottom). The Geiger-Muller tube is an instrument for detecting and measuring ionizing radiation. The tube contains a gas that ionizes and produces an electrical pulse in a wire when ionizing radiation passes through it. Americium-241 emits alpha particles. | |
