Geiger-Müller (GM) Detectors

Geiger-Müller (GM) detectors, named after the physicists Hans Geiger and Walther Müller who invented them in the early 20th century, are widely used radiation detectors with applications ranging from scientific research to everyday life. These detectors operate based on the ionization produced by radiation in a gas-filled chamber, enabling them to detect various types of ionizing radiation. Despite their origins in scientific exploration, Geiger-Müller detectors have found practical use in numerous real-world scenarios due to their simplicity, reliability, and versatility. They play a crucial role in safeguarding public health and the environment. In this section, a series of experiments, based on CAEN “RockyRAD”, are presented to explore the principles behind Geiger-Müller detectors and their diverse applications in everyday life.
