Determination of the spatial distribution of the scattered energy from a monodirectional point source presents great difficulties because the kinetic equation contains 5 variables. In order to clarify the problem, the radiation from a narrow pencil of radiation was studied using an aqueous 90 x 90 x 90-cm phantom. Strongly collimated gamma rays from Cs¹³⁷ and Co⁶⁰ sources were directed on the front wall of the phantom. Measurements by means of a scintillation detector with an organic crystal were carried out in the plane normal to the axis of the beam. An equation was derived for expressing the energy distribution of the narrow beam on variables such as distance from the beam axis, the linear attenuation coefficient, beam energy, etc. The experimental and theoretical data agree with each other within 10%; good agreement was also obtained msking use of the build-up factors reported by H. Goldstein and S. Wilkins (AEC Report, NYO-3075(1954)). (TTT)
