Effective atomic numbers (Z(eff)) of polypyrrole have been determined for total photon interactions in the energy range 15.74-40.93 keV from the accurately measured total attenuation coefficients, for characteristic K and K X-rays of Zr, Mo, Ag, In, Sb, Ba and Pr. The results were compared with the theoretical atomic numbers obtained using the XCOM. (c) 2007 Elsevier Ltd. All rights reserved.
