A Monte Carlo study of the backscattering coefficients and backscatteringintensity of ..beta.. rays from /sup 204/ Tl and /sup 90/ Y sources from slabs of Al,Cu, Sn, Tb, and Pb of different thicknesses is carried out. The results forangles of incidence 0/degree/, 30/degree/, 45/degree/, and 60/degree/ and absorber thicknesses of 3,5, 10, 15, 30, and 50 mg/cm/sup 2/ for /sup 204/ Tl ..beta.. rays and thicknesses of3, 5, 10, 20, 50, 100, 150, and 190 mg/cm/sup 2/ for /sup 90/ Y ..beta.. rays aregiven in tabular form. On using normalization factors good agreement with themeasurements of Sharma and Singh is obtained. A phenomenological attempt toinvestigate a relationship between the backscatter intensity and atomic number/ital Z/ of the backscatterer indicates that the backscattered intensity is alinear function of ln /ital Z/(/ital Z/+1). A partial theoretical justification forthis relationship is given.
