X-rays used for radiotherapy

Question

Quizplus · Accepted Answer

X-rays used for radiotherapy are typically in the megavoltage range (MV) of energies, which is important for their ability to penetrate deeper into the body and target tumors while minimizing damage to healthy tissue. MV X-rays are produced by linear accelerators (linacs) rather than Cobalt-60 sources and are usually not monoenergetic, but rather have a range of energies. Additionally, MV X-rays do require filtration to remove low-energy photons that could scatter and cause unwanted dose to healthy tissue.
