THE BACKSCATTERING OF GAMMA RADIATION FROM PLANE CONCRETE WALLS

Technical Report ·
OSTI ID:4710814
Monte Carlo calculations were performed for source energies from 1 to 10 Mev, and normally incident radiation, showing that 90% of the infinite-barrier energy flux albedo is reached with a 10-cm concrete wall. The spectrum of back- scattered energy fiux is presented for the above sources and wali thicknesses ranging from 5 to 50 cm. An analytical expression, based on a single-scattering approximation, is shown to produce good fits to the Monte Carlo results. (auth)
