Buildup Factors

The effective atomic number and effective electron density in amino acids are of significant interest due to their use in various applications. The energy absorption buildup factors, exposure buildup factors, effective atomic numbers, and electron densities of essential amino acids such as Leucine (C6H13NO2), Lysine (C6H14N2O2), Methionine (C5H11NO2S), Phenylalanine (C9H11NO2), Threonine (C4H9NO3), Tryptophan (C11H12N2O2), Valine (C5H11NO2), Arginine (C6H14N4O2), and Histidine (C6H9N3O2) were determined theoretically in the energy range 0.015–15 MeV.

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.
