Production and Neutron Irradiation Tests on a New Epoxy/Molybdenum Composite

Abstract

Molybdenum powder was added in an epoxy matrix to increase the neutron-shielding capacity of pure epoxy. FLUKA and GEANT4 Monte Carlo programs were used to design new neutron-shielding material. After finding the epoxy/Mo ratio for the best shielding capacity, neutron equivalent dose rate measurements were performed. Results were compared to commonly used neutron-shielding materials such as paraffin, steel, concrete, and B4C. The produced new sample has a high neutron shielding capacity and it can be used for neutron protection purposes.
