The objective of this research is to analyze the attenuation of primary radiation and the production of secondary particle regolith composites. Composites of regolith are considers as an option for in-situ structural material for NASA’s Lunar and Martian missions. This project is a cross-disciplinary research involving material fabrication, characterization, irradiation and transport simulations

The objective of this project was to validate and benchmark two transport codes (MCNPX, PHITS) against the quantitative experimental data. The experimental data of comparison was preformed at the Space Radiation Effects Laboratory in Newport News, Virginia. The comparison was for neutron produced from high energy (710 and 640 MeV) alpha particle colliding onto water and lead target. The neutron spectral characteristics were compared at 9 different angles

Quantitative analysis of neutron intensity and spectral characteristic are necessary for design of medical LINAC. This information is vital for target optimization, therapy room design, shielding, patient and by-standard dose assessment. The focus of this research is to characterize photoneutron produced from bremsstrahlung generated through electron interaction in high Z targets
