RADIATION PHYSICS
RADIATION PHYSICS
Radiation can be produced electronically, as in x-rays or electrons, or via the disintegration of unstable isotopes, as seen in alpha, beta, and gamma rays. Isotope therapy such as brachytherapy, or implantation techniques, may result in a less homogenous dose pattern. In dermatology, when treating with radiation, most lesions are treated by teletherapyโelectronically produced radiation delivered at a distance from the radiation source. Photonic teletherapy is the radiation source for SRT.17
