What is a GM Counter? - Geiger Muller Counter
Geiger Muller Counters, or GM Counters, are very common and easily available nuclear particle detectors. It works on the principle that in the presence of a strong potential difference, a nuclear particle which causes ionization in gaseous molecules can lead to an avalanche of secondary ionizations that results in a sudden discharge, and therefore detection of the particle. Such an avalanche is known as Townsend Avalanche.
In this video I talk about the construction and the Principle on which a GM counter works. I also discuss the Dead Time, Chemical and External Quenching of Geiger Muller Counter.
