Abstract:

This thesis examined the suitability of a particle simulator known as Monte Carlo n-Particle 6 MCNP6 to determine how well U.S. Army vehicles shield their occupants from gamma radiation. MCNP6 compared favorably to three alternate modeling approaches and another particle simulator. In a validation experiment, MCNP6 was found to produce a gamma protection factor within 5 of the experimental result with 95 confidence. Further evaluations validated MCNP6s ability to produce reliable results with simplified or approximated inputs, model different sources, and position those sources in different shielding geometries. MCNP6 is suitable for evaluating gamma protection of Army vehicles and further research to explore the effects of different shielding shapes and evaluate the suitability for MCNP6 to calculate a comprehensive radiation protection factor is warranted.
