"WebIon chambers are similar to GM counters in that they use a gas-filled chamber with a voltage applied across it. The voltage is lower than in GM counters, around 105 V. This allows for proportional counting of the energy received from radiation as opposed to simply counting the number of pulses. " - Ion chamber gas
