PlateauFor the simple electronic circuits that are usually designed for use with Geiger-Mueller tubes a minimum pulse amplitude is required for count registering. At a given voltage this minimum pulse amplitude is exceeded by all signals, as soon as that voltage, the Geiger discharge region, is reached. Therefore, on increasing the voltage while exposing the Geiger-Mueller tube to a radioactive source of constant activity, pulse registering starts rather abruptly and the counts per unit of time remain relatively constant (plateau of a Geiger-Mueller counter).Geiger-Mueller tubes are frequently rated on the basis of the slope of the plateau region. The slope of the plateau region of halogen-quenched tubes is usually less flat than that of organic-quenched tubes (2–3% per 100 volts). But halogen-quenched tubes can usually be operated at a lower voltage than organic-quenched tubes."
