Adjoint Monte Carlo Generated Radiation Response Functions for the B-1 Aircraft.

Abstract

The adjoint Monte Carlo radiation transport technique is used to calculate radiation response functions for the B-1 aircraft. These radiation response functions are given for the neutron dose and also for the neutron plus the secondary gamma dose. The response functions are given for the head and stomach positions of the left front crew member. They can be folded with any angle and energy dependent neutron and/or gamma ray free field exposure to give the radiation dose. The MORSE multigroup, coupled neutron-gamma ray, Monte Carlo code is used for the adjoint transport in the B-1 aircraft which is modeled with combinatorial geometry. The theory and equations needed to evaluate the coupling integral in terms of the statistical weight of the adjunction on the coupling surface are developed.
