Geiger tube
Basic information of ionization radiation counting tube:
According to the gas discharge method, counting tubes are divided into:
Proportional
Ionization
Geiger-Mueller
Among them, Geiger-Mueller counting tube (referred to as Geiger tube) can be used to record alpha, beta, and gamma radiation. Due to its high sensitivity, simple structure, and low cost, Geiger tube is widely used in dose and radiation measurement equipment.
