Abstract The radiation shielding characteristics of 50 wt% WO$_{3}$/E44 epoxy composite in various gamma energies from 80 keV to 1.33 MeV are investigated via the MCNP code. Thus two scales are considered for WO$_{3}$ filler particles: micro and nano with sizes of 1 μm and 50 nm, respectively. The simulation results show that WO$_{3}$ nano particles exhibit a larger increase in linear attenuation coefficient in comparison with micro size particles. Finally, validation of simulation results with the published experimental data shows a good agreement.
