Out‐of‐field neutron radiation from clinical proton, helium, carbon, and oxygen ion beams
Medical Physics, Volume 52, Issue 6, Page 4924-4940, June 2025.Abstract Background In hadron therapy, out‐of‐field doses, which may in the long‐term cause secondary cancers, are mostly due to neutrons. Very recently, 4He and 16O beams have been added to protons and 12C ions for clinical therapy. Purpose The focus of this article is to compare secondary neutron doses produced by clinical protons, 4He, 12C, and 16O ...

Design of portable shield for neutron sources using MCNP Computer Code [PDF]
Arab Journal of Nuclear Sciences and Applications, 2018 In this work a proposed design of portable shield for neutron sources was performed theoretically using MCNP5 code. The shield is composed of three layers; lead layer for gamma attenuation, PMMA (Poly-methyl methacrylate) layer for fast neutron thermalization and a layer of B2O3 for thermal neutron absorption.
