X-ray attenuation coefficients of Fe compounds in the K-edge region at different energies and the validity of the mixture rule
Özet
The total mass attenuation coefficients for element Fe and compounds FeF3, Fe2O3, FeCl2 (.) 4H(2)O, FeCl(3)2NH(4)Cl (.) H2O were measured at different energies between 4.508-17.443 keV range by using secondary excitation method. Ti, V, Cr, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo were chosen as secondary exciter. 59.5 keV gamma rays emitted from an Am-241 annular source were used to excite secondary exciter and K-alpha(K-L-3, L-2) lines emitted of secondary exciter were counted by a Si(Li) detector with a resolution of 160 eV at 5.9 keV. It was observed that mixture rule method is not a suitable method for determination of the mass attenuation coefficients of compounds, especially at energy that is near the absorption edge. Obtained values were compared with theoretical values. (C) 2004 Elsevier Ltd. All rights reserved.
