Please provide a name for this query: International Atomic Energy Agency. The energy parameters characterizing the electron and photon beams have been obtained from measured depth dose distributions carried out by a plane parallel ionization chamber NACP. Two independent dosimeters were used with two ionization chambers each one, respectively. In this case, chamber dependent conversion factors are required to determine absorbed dose to water.

The measurements have been performed in two linear accelerators Clinac C Varianwith electron beams of nominal energies between 6 and 20 MeV, corresponding to R 50 from 2.
Beams that are generated by an accelerator Elekta Linac SL It is determined by two different protocols: In other hand, the use of protocol with a more simple formalism reduces the possibility of errors.
Differences in the absorbed dose determined by the three protocols are less than 0. Please provide a name for this query: The quality for electrons beams were estimated by means of the Dmax, R80, R50 and Rp.
