The effective atomic number (Zeff) and effective electron density (Neff) of wrought aluminum alloy 7010 has been determined by measuring mass attenuation coefficient (μm), total atomic cross section (σt) and total electron cross section (σe) with radioactive point source of different γ-energies viz. 59.5, 661.16, 1173 and 1332 keV. The transmitted γ-photons were detected and recorded by a NaI(TI) scintillation detector with resolution of 8.5% for 661.16 KeV of 137Cs. The experimental results determined were compared with the theoretical values obtained using XCOM and semi empirical approach for all photon energies. The photon mean free path (λ) and linear attenuation coefficient (μl) for these energies have been reported. The experimental values are in good agreement with theoretical values.
