Supervoltage Therapy

  • G. J. van der Plaats


The most modern method of increasing the depth dose is to use very hard radiation. After it became clear that increasing the voltage from 200 kV to 1000 kV (= 1 MV) gave little increase in the depth effect, one began paying attention to radiation of even higher energy. This energy is expressed in electron-volt (eV) and most of times the very hard radiations are characterized by the energy of their photons, which is several mega-electronvolts (MeV).
