- Abstract
Despite the importance of photoneutrons doses produced in the high-energy linear accelerators, currently they are not considered in the treatment planning systems. Therefore, it is necessary to characterize the photoneutrons produced around the linacs. For this purpose, the main components of head of 15 MV Siemens Primus were simulated using MCNPX 2.6. Neutron contamination was calculated in the treatment room at the isocenter. The maximum dose equivalent of neutrons was found in 25 cm × 25 cm field size. Neutron spectrum was also measured applying the Bonner sphere with gold foils and artificial neural network as unfolding method.
