MCNP Results for Nanocomposite Shielding in High-Energy Proton Fields

Monte Carlo radiation transport results for various physics schemes (neutron + proton, neutron + proton + delta ray, and neutron + proton + delta ray + light recoil ions) and nanocomposite structural models (bulk homogenous material, hollow carbon cylinders suspended in polymer matrix, and carbon spheres in nanotube structure suspended in polymer matrix) of a polymer-carbon-nanotube nanocomposite shielding material in high-energy proton beams of 63 MeV and 105 MeV.
