Abstract

Experimental data regarding the spectral and angular distribution of y quanta back-scattered from various scattering substances are presented for the geometry of an isotropic point source; the scattering substances include paraffin, graphite, aluminum, iron, xinc, cadmium, and lead (semiinfinite media). The energy of the primary ~/radiation was 0.145; 0.190; 0.279; 0.320; 0.396; 0.661 and 0. 765 MeV. The numerical and energetic albedos (A and AE) determined experimentally agree closely with the values calculated by the Monte-Carlo method. The results are presented in the form of tables and graphical relationships for A, AE, and A/AE as functions of Z and Eγ.
