What type of radiation does a linear accelerator produce?
Radiation therapy linear accelerators produce high energy electron beams (6MeV to 16 MeV). The electron beams are used to treat superficial regions of the body, like surgical scars or skin cancers. In order to treat internal organs, the electron beam is passes through a Tungsten target in the machine head, converting the energy from the electrons into high energy X-rays. X-rays penetrate much deeper into and through the body. READ MORE
How soon after radiation do side effects start?
Radiation therapy is given in small doses once per day over 6 to 9 weeks so that normal tissue can tolerate larger total doses. Side-effects usually take two to three weeks to begin, but then linger for two to three weeks after treatment is finished.
