MONTE CARLO CALCULATIONS OF GAMMA-RAY STREAMING THROUGH COPLANAR AND NONCOPLANAR DUCTS.

Abstract

Past experimentation with the streaming of gamma radiation through models of ducted entranceways by using high intensity Au198, Cs137, and Co60 gamma-ray sources has proved to be time consuming. As a means of reducting expenses, a Monte Carlo computer program for studying gamma-ray streaming was utilized. The Monte Carlo technique, using the ADONIS computer code developed by the United Nuclear Corporation, was used to calculate gamma-ray dose rates and energy spectra within two-legged and three-legged rectangular air ducts through concrete. These calculations were performed to intercompare a coplanar and a noncoplanar configuration for Co60 gamma-ray streaming through a three-legged duct. The results of the Monte Carlo calculations are compared with previously obtained experimental findings. The agreement between the Monte Carlo method and previous experiments supports the validity of using the Monte Carlo method to simulate the behavior of gamma rays in ducts. (Author)
