Background: High-energy linear accelerator (linac) is a valuable tool and the most commonly device for external beam radiation treatments in cancer patients. In the linac head, high-energy photons with energies above the threshold of (γ...

Introduction and Purpose: Photoneutron production is an important problem during patient radiotherapy with high-energy linear accelerators. In this study, the contribution of some components of accelerator head was investigated. Then it has been...

A simple Monte Carlo procedure is described for simulating the multiple scattering and absorption of electrons with a definite incident energy in the range of keV up to 20 MeV, moving perpendicular or at a definite angle ...
