Variation of Mass Attenuation Coefficient, Effective Atomic Number, and Electron Density with Incident Photon Energy of Some Organic Acids

Mass attenuation coefficient, effective atomic number, and electron density of 12 organic acids, acetic acid (C₂H₄O₂), acrylic acid (C₃H₄O₂), benzoic acid (C₇H₆O₂), butyric acid (C₄H₈O₂), citric acid (C₆H₈O₇), formic acid (CH₂O₂), lactic acid (C₃H₆O₃), malic acid (C₄H₆O₅), oxalic acid (C₂H₂O₄), salicylic acid (C₇H₆O₃), tartaric acid (C₄H₆O₆), and valeric acid (C₅H₁₀O₂), were computed in the wide energy range of incident photon energies from 1 keV to 100 GeV. The variation of these parameters has been studied as a function of incident photon energy. Further, a comparative study of two different methods used to compute effective atomic number is completed.
