APPLICATION OF THE MCNP6.1 CODE TO ESTIMATE THE DIRECTIONAL DEPENDENCE OF RADIATION PROTECTION FACTOR VALUES FOR A SIMPLE SURROGATE VEHICLE.

Radiation protection factor (RPF) values are relevant to various US defense and civil support organizations. An equation was developed to quantify the angular-dependent protection of a shielding configuration in the presence of a mono-energetic radiation field. Values of ambient dose equivalent, H*(10), were computed with version 6.
