Self mass attenuation coefficients for mixture of some 3 d elements Ni 100x Alx and Zn 100x – Alx at Am-241 ( 40 mCi )

In this paper we study the mass attenuation coefficients (μm) for Ni100-x Alx, Zn100xAlx ) mixtures with different weight ratios. These mixtures were prepared by mixing the Nickel (Ni) and Zinc (Zn) with different concentration of Al (x = 10-50) using ball milling technique. The mass attenuation coefficients (μm) were measured by self attenuation of characteristics X-rays. The Gamma rays of 59.6 KeV emitted from 241Am source were used to excite the mixture samples and emitted Kα and Kβ X-ray lines were counted by a Silicon Drift Detector (SDD) with a resolution of 150 eV at 6.4 KeV. The samples have also been characterized by SEM and EDXRF measurements. The obtained results were compared with theoretical values and are agreement with theoretical results.
