Qui The operating principle of the GM counter: yet 1 Select one weed out al O The ionization of gas atoms filling the tube is caused by the charged particles or gamma photons 6 that reach the device through a window at the end of the tube. usto The material filling the tube is usually Nal doped with thallium Finis The potential difference between the anode and cathode of the GM counter is in the few hundred milivolt [mv] range. Time The refractory period of the GM counter is the time between the arrival and the detection of a charged particle or gamma photon. The avalanche-like charge multiplication process is the result of primar
