A gas-filled radiation detector operating in the proportional region is exposed to a constant gamma radiation field.
If the applied voltage is increased but maintained within the proportional region, the rate of ion collection will…
A. increase, because more secondary ionizations are occurring in the detector.
B. increase, because fewer primary ions are recombining in the detector prior to reaching the electrodes.
C. stay approximately the same, because the ion chamber is operating at saturated conditions.
D. stay approximately the same, because all of the primary ions were already being collected at the lower voltage.
