Popis:	The transmitted γ ray fluxes for three sources, namely, 241Am, 57Co and 203Hg, for the total spectrum as well as for the multiple-scatter peak, for different thicknesses of the water and graphite media have been represented by the diffusion formula, I = S(4πDxekx), and compared with the earlier representation, I = Ioe−ax. It is found that both the representations are equally good for the medium thicknesses taken in these measurements.
