The mass attenuation coefficient of Inconel 738 superalloy has been measured at different gamma ray
energies by using the Compton scattering technique. The theoretical values of mass attenuation coefficient
of a glass sample were calculated using WinXCom program. The effective atomic number and electron
density are also calculated. The results showed that the mass attenuation coefficients, effective
atomic number and electron density increase with the decrease in gamma ray energies which is in good
agreement with theoretical values (less than 2% error).
