A study on the mean free path and half value layer at various alloys for different photon energies

Abstract

The mean free path (mfp) and half value layer ( $x_{1 / 2}$ ) values of binary and ternary alloys consist of 3d transition metals have been have been calculated at photon energies 22.1, 25.0, 59.5 and 88.0 keV. The experimental linear attenuation coefficients (μ) for present photon energies have been used to obtain the values of mfp and $x_{1 / 2}$ . The experimental mfp and $x_{1 / 2}$ results have compared with the theoretically calculated results based on attenuation coefficients obtained from WinXCom program. A good correspondence has been observed among the present results and the theoretical results.
