A beta particle and an alpha particle with equal kinetic energies cause ionization in a gas-filled radiation detector.
The detector is operating in the ion chamber region of the gas ionization curve.
Which one of the following describes the amplitudes of the detector pulses caused by each type of radiation?
A. The beta particle pulse will be larger in amplitude.
B. The alpha particle pulse will be larger in amplitude.
C. The amplitudes of both pulses will be approximately equal for all detector voltages in the ion chamber region.
D. The amplitudes of both pulses will be approximately equal for all detector voltages in the ion chamber region, as well as all detector voltages outside the ion chamber region.
