Mass Attenuation

The effective atomic numbers and electron densities of some synthesized triazoles were determined using the experimental values of total mass attenuation coefficients at 13.93, 17.77, 26.34, and 59.54 keV photon energies. The measurements were performed in a transmission geometry that consists of a Si(Li) detector, an 241Am point source and a target. The measured results were compared with two different theoretical results. The measured results are generally consistent with the theoretical results. It is observed that the measured parameters depend on the photon energy, weighted contributions of the individual atoms within the triazoles, atom number in the triazoles, and chemical composition of triazoles. Also, the effective electron density increases linearly with increasing effective atomic number.

Mass Attenuation

In this work, total mass attenuation coefficients and effective atomic numbers of a series of three host glasses with different chemical composition, 65RmOn: 10CaO : 25Na2O mol% (where RmOnare B2O3, SiO2and P2O5, respectively) have been studied as a function of photon energy. The total mass attenuation coefficient values were taken from WinXCom program, were used to evaluate the effective atomic numbers in the energy range from 1 keV to 100 GeV. The obtained results for all samples are compared and discussed.
