Geiger-Muller tube

A Geiger-Muller tube is a device used to detect and measure ionizing radiation, such as alpha, beta, and gamma rays. It consists of a gas-filled tube with electrodes that becomes conductive when radiation passes through it, ionizing the gas. This creates a pulse of electric current, which can be counted and displayed, indicating the level of radiation present. Commonly found in Geiger counters, these tubes are essential for safety in environments where radiation is a concern, such as in nuclear facilities or medical applications, providing crucial information about radiation exposure.
