Abstract

The effective atomic numbers for total and partial photon interactions of 11 different biological samples have

been determined using a new approximation in the energy region 10±150 keV. In this study, `mass attenuation

coefficients' for the various individual interactions have been calculated. The effective atomic numbers have been

obtained by considering the Z--dependence of photon cross-sections and the variation of Z--exponents with energy.
