A Monte Carlo procedure was developed to evaluate the energy, angular d ribution, and intensity of either the scattered neutron or gamma-ray flux that penetrates a multibend duct. A detailed presentation of the Monte Carlo method as an ap proximation to the Neumann series solution of the integral transport equation is given. Sampling techniques utilized by the procedure are described. Included in these techniques are splitting, Russian Roulette, statistical estima tion, and a method of biasing the sampling from the source angular distributions. Results ob tained with the procedure are compared with the data taken in the duct penetration and systemiza tion experiment.
