"WebIonization chambers are handheld survey instruments used to measure low or high exposure rates (Fig. 2-2 ). They have an air or gas-filled chamber but a low efficiency for detection of gamma rays. These instruments have a relatively low applied voltage from anode to cathode; as a result, there is no avalanche effect and no dead time problem. " - Ionization chambers
