Study of mass attenuation coefficients, effective atomic numbers and electron densities for some low Z compounds of dosimetry interest at 59.54 keV incident photon energy

Total mass attenuation coefficient, total photon interaction cross-section, effective atomic numbers (Z(eff)) and electron densities (N-e) of Aniline (C6H5NH2), Cyclohexane (C6H12), Glycerine (C3H5(OH)(3)), Butyl alcohol N-(C4H9OH), DMSO - dimethyl sulfoxide (C2H6OS), Methyl ethyl-ketone (C4E8O), Xylene (C8H10), Acetophenone (C8H8O) and Triethyl amine (C6H15N) have been measured at 59.54 key energy photon emitted by 100 mCi Am-241 point source employing narrow beam transmission geometry. Obtained results have been compared with theoretically calculated values of XCOM (Berger and Hubbel, 1987) and FFAST (Chantler et al., 2005). Mixture rule was employed to calculated theoretical mass attenuation coefficient values for each sample. Good agreement has been observed between experimental and theoretical values within experimental uncertainties. (C) 2011 Elsevier Ltd. All rights reserved.
