The Mass Attenuation Coefficients and Effective Atomic Numbers of Ruby from Vietnam at Different Photon Energies

Abstract:

The mass attenuation coefficients and effective atomic numbers of ruby from Vietnam were measured at the different energy of γ-rays using the Compton scattering technique. The compositions of ruby were analyzed by energy dispersive x-rays fluorescence spectrometer and showed the Al₂O₃ is major composition. The results of the experimental values of mass attenuation coefficients and effective atomic numbers showed the good agreement with the theoretical values. The mass attenuation coefficients decreased with the increasing in gamma rays energies, due to the higher photon interaction probability of ruby at lower energy. The effective atomic numbers found to be constant around 10.0 electrons/atom.
