Effective atomic number study of various alloys for total photon interaction in the energy region of 1 keV–100 GeV

Effective atomic numbers of various alloys have been calculated by using a direct method for total photon interaction ( Z P I eff ) in the energy region of 1 keV–100 GeV. Significant variations in Z P I eff observed for alloys in different energy regions are mainly dominated by photoelectric and pair production processes. Besides, the Z P I eff has been found to vary with the composition of alloys. Comparisons with experiments have been carried out for calculated values of Z P I eff . Also, the energy dependence of Z P I eff with respect to the atomic number of constituent elements present in the alloys and K-absorption edge effects on effective atomic numbers where there exists more than a single value of effective atomic number at a specific energy have been discussed for the given alloys.
