Utilization of Polymeric Composites for Neutrons and Gamma-Rays Attenuation

Abstract

This thesis is concerned with the investigation of the mechanical, physical and radiation attenuation properties of some shielding materials. Selected shields of polyester styrene and epoxy composites were chosen to fulfill certain applications and are concerned for the present work. Both resins (Polyester and Epoxy) were filled with crushed magnetite, ilmenite and barite fillers, as well as, boron carbide for homogeneous shields. Also, boron glass disks were coupled with the Epoxy-Ilmenite formula in one assembly to perform multilayered shields. Both basic formulas and polymeric substances, in general, are hydrocarbonic substances which guarantee good neutron moderation and attenuation. Furthermore, heavy minerals and boron additives were employed for gamma rays attenuation and thermal neutrons capture respectively.
