Determination of Aluminum in Copper-Aluminum Alloy Using Gamma-Ray Spectrometry

In this work, a nuclear gauge, based on single and dual energy γ-ray
transmissions, has been developed and used to determine the concentrations of
the aluminum component in copper-aluminum alloy. Disk foils of 7.07 cm2 area
and thicknesses ranging from 0.48 to 0.834 cm have been prepared from the
alloy to be used as targets for the γ-ray photons. Criteria for the best choice of
the suitable photon energies for both single and dual energy γ-ray transmissions
have been investigated. In this work, aluminum concentration values with an
accuracy of 98.53% and 99.09% have been obtained by using both single and
dual γ-ray energy transmission techniques, respectively. A comparison of the
present results with those from the conventional chemical analysis indicates a
fair agreement. A criterion for the best choice of the suitable γ-ray transmission
technique for the aluminum determination has been investigated.
