The mass attenuation coefficient (mu(m)), the mass energy absorption coefficient (mu(en)/p), and kerma relative to air were determined for some alloys, namely Fe-0.5 Cr-0.5, Fe-0.7 Cr-0.3, Fe-0.8 Cr-0.2, Fe-0.9 Cr-0.1, Fe-0.2 Ni-0.8, Fe-0.3 Ni-0.7, Fe0.5Ni0.5, Fe0.6Ni0.4, Fe0.7Ni0.3, and Fe0.8Ni0.2, at 17.44, 19.63, 22.10, 24.90, 32.06, 36.39, 37.26, 43.74, 44.48, 50.38, and 51.70 photon energies by using an HPGe detector with a resolution of 182 eV at 5.9 keV. The experimental results of pm were compared with the theoretical results. The theoretical values of mu(en)/p were compared with the semiempirical values. It was observed that kerma values relative to air values were different in Fe Ce and Fe Ni alloys due to photoelectric cross sections depending on the atomic numbers of the material.
