Depth for dose calibration in high energy photon beams

AbstractBackground and purpose: The normalisation depth for determination of output factors in photon fields has frequently been the depth ofdose maximum. At high energies the contribution from contaminating electrons is significant at dose maximum and is critically dependenton the beam geometry parameters, which is why a larger depth should be preferred.Materials and methods: The effect of electron contamination was studied using a purging magnet to remove charged particles from thetreatment he ...
