Gc. Bakos et Nf. Tsagas, ANGULAR PROPERTIES FOR COMBINED 6.13-MEV AND 7.12-MEV SOURCE PHOTONS PENETRATING CONCRETE, STEEL AND LEAD, Annals of nuclear energy, 23(13), 1996, pp. 1061-1068
In this paper, experimentally determined angular flux spectra for comb
ined source energies of 6.13 and 7.12 MeV, penetrating single layer sh
ields of concrete, steel and lead are examined. A method for the calcu
lation of the scattered photons energy, when multi-energy photons are
emitted from a radioactive source, is described. Changes in the total
scattered photon energy spectrum, as a function of polar angle and shi
eld thickness are discussed. Copyright (C) 1996 Elsevier Science Ltd
