How Does a Geiger Counter Work?

A Geiger counter, also known as a Geiger-Müller counter, is a device designed to detect and measure ionizing radiation, including alpha particles, beta particles, and gamma rays. It operates on a straightforward yet effective principle: when radiation passes through the counter, it interacts with the gas inside a sealed tube, which is typically filled with an inert gas like helium or neon. This interaction ionizes the gas, generating charged particles (ions and electrons). These charged particles are attracted to electrodes within the tube, resulting in a measurable electrical pulse. Each pulse corresponds to a radiation event, allowing the Geiger counter to provide readings in counts per minute (CPM) or microsieverts per hour (µSv/h). This technology is widely utilized in various fields, including nuclear safety, environmental monitoring, and medical applications, making it an essential tool for detecting radiation and ensuring safety in radiation-prone environments.
