SUMMARY
The discussion clarifies the structural and functional differences between ionization chambers and Geiger-Müller (GM) tubes. Ionization chambers operate at normal gas pressure and are connected to galvanometers, while GM tubes function at low pressure and are linked to counters. The application of higher voltage in GM tubes facilitates electron avalanche, a feature not utilized in ionization chambers under standard conditions. This distinction is crucial for understanding their respective applications in radiation detection.
