D)the 70 kVp beam would demonstrate an equal amount of brems and characteristic radiation.

Question

Quizplus · Accepted Answer

At higher kilovoltage peaks (kVp), there is an increase in the number of bremsstrahlung (brems) photons due to the increase in the energy of the electrons in the anode interacting with the tungsten atoms. This leads to a higher probability of electrons being slowed down or stopped by the target atoms, causing the release of a brems photon. However, at higher kVp, there is also an increase in the probability of characteristic photons being produced as more electrons are accelerated to higher energy levels in the anode. Therefore, the 110 kVp beam would demonstrate more brems and a higher characteristic spike compared to the 70 kVp beam.
