Neutron Scattering Dependence on Proximate Human Tissue from Fast Neutrons

Neutrons incident on a human may undergo scattering, altering their energy. It is necessary to acknowledge that a proximate human moderator may non-trivially alter the neutron flux and source spectrum for a given neutron detection/spectroscopic device. Using primarily the Monte Carlo N-Particle (MCNP) transport code, the neutron-human moderator dependence will be discussed with respect to the rigorous quantification of human tissue composition and proximity/geometry on neutron moderation. MCNP simulated results will then be discussed in view of empirical results.
