The total mass attenuation coefficients (μ/ρμ/ρ), for pure Ti, Co, Cu and TixCo1-xTixCo1-x and CoxCu1-xCoxCu1-x (x = 0.8, 0.7, 0.6, 0.5, 0.4, 0.3 and 0.2) alloys were measured at 22.1, 25.0, 59.5 and 88.0 keV photon energies. The samples were irradiated with 109Cd and 241Am radioactive point source using transmission arrangement. The X- and γ-rays were counted by a Si(Li) detector with resolution of 160 eV at 5.9 keV. Total atomic and electronic cross-sections (σtσt and σeσe), effective atomic numbers (Zeff) and electron densities (Nel ) were determined using the obtained μ/ρμ/ρ values for investigated 3d alloys. The theoretical mass attenuation coefficients were estimated using mixture rule and the experimental values of investigated parameters were compared with the calculated values.
