Abstract

Monte Carlo simulations using MCNP4A and experimental work have been performed to evaluate the contribution of electrons that are produced in air from a 6 MV x-ray beam produced by a medical linear accelerator. Results show that up to 9% of applied dose is delivered to a patient's skin surface from electrons excited in the irradiated air column. For most field sizes this constitutes approximately 30% of dose delivered to this region. This study gives clinically relevant information on the origins and quantity of electrons at the skin of patients undergoing radiation therapy.
