Mass Attenuation

The effective atomic number, electron density and mass attenuation coefficient of some selected active pharmaceutical ingredients such as Diclofenac Sodium, Femotidine, Alprazolam, Amiodar, Amiodarone, Ciprofloxacin, and Nimesulide have been calculated over the energy range from 1 keV to 100 GeV for total and partial photon interactions by using WinXCom. The obtained data shows that the change in mass attenuation coefficient and electron density varies with energy and chemical composition of the active pharmaceutical ingredients (API’s) in drugs. The results in the variation of photon interaction with energy and effective atomic number of the API’s in drug are shown in the logarithmic graphs.

Mass Attenuation

This work proposes a mathematical function for describing the dependence of mass attenuation coefficients vs. energy for composite materials in the range of 100 keV to 2 MeV. The obtained results show that the proposed function is capable of accurately describing the data with a coefficient of determination of approximately 1 for all investigated materials. Using the proposed mathematical function, the mass attenuation coefficients were interpolated and compared with the results from the Monte Carlo simulation. The results show good agreement when the simulated to interpolated mass attenuation coefficient ratios are in the range from 0.95 to 1.05. Moreover, the values of interpolated mass attenuation coefficients have also been compared with the experimental data in the previous works which indicates that most of these ratios range from 0.9 to 1.1. <br><br><font color="red"><b> This article has been corrected.
