- gradually replaces the cobalt-60
- produces gamma rays, x-rays and electrons; more energetic than cobalt-60.
- operates at 4 MeV to 20 MeV
- the charged particles travel in a straight line as they gain energy from alternating EM field.
- higher energy beams can be generated with greater skin sparing.
- field edges are more abruptly design with less penumbra and personnel receive less [...]
