Monte Carlo Design and Experiments on the Neutron Shielding Performances of B2O3–ZnO–Bi2O3 Glass System

Abstract

Neutron shielding properties of (90 – x)B2O3–10ZnO–xBi2O3 glass systems (where x = 15, 20, 25 and 30 mol %) were investigated by Monte Carlo simulations (FLUKA and GEANT4) and experiments. Neutron mass removal cross sections, number of inelastic scattering, elastic scattering, and capture interactions were estimated by simulations. 241Am/Be neutron source was used for the neutron equivalent dose rate measurements. As a result, produced glass samples have fine neutron shielding capacity.
