Abstract : A Monte Carlo computer code was assembled to calculate the transport of gamma rays in three-dimensional, rectangular geometry. The code uses the statistical estimation technique to compute the flux and dose at several space points. The code was applied to two compartmented iron structures that had been experimentally investigated. The Monte Carlo and experimental results compare well, i.e., within 20 percent, in most cases. In a few cases for one structure, where the radiation was incident at large angles from the normal to one wall, the comparison between the results was less than satisfactory. The experimental value was a factor of 6 greater that the Monte Carlo value in the worst case. (Author)
