ABSTRACT Background: In a high-energy medical linear accelerator (linac), if the interaction of photon energy is higher than neutron binding high atomic material, it emits field through photonuclear (γ, n) reaction. Aim: The current study, evaluates photoneutron dose equivalent (PNDE) produced between 10 MV flattened and unflattened beams as function sizes in Elekta Versa HD™ linac. Materials Methods: PNDE from linac was recorded along patient plane using bubble detector personal dosimeter...
