MONTE CARLO CALCULATIONS ON THE REFLECTION AND TRANSMISSION OF SCATTERED GAMMA RADIATIONS. Final Report, July 1961
Monte Carlo calculations were performed to determine the back-scattering and the transmission of gamma rays having energies between 0.02 and 10.0 Mev from concrete. The radiation was assumed to be incident on a semi-infinite medium and on various slab thicknesses of 0.5, 1.0, 2.0, and 4.0 mfp at angles of cos THETA /sub 0/O = 1.0, 0.75, 0.50, 0.25, and 0.10. The case histories of 5000 photcns were followed on the IBM 704 digital computer. The information obtained included: the characteristics of emergent photons, which were stored on magnetic tape; a routine that processes these characteristics to give polar and azimuthal angular dose distribution; detailed results from the application of the processing routine to the parameters investigated. The computer program, the processing routine, and the results are appended. (auth)
