Photon energy absorption parameters for some polymers

Some photon energy absorption parameters viz. mass energy absorption coefficient (mu/rho)(en), photon energy absorption effective atomic number (Z(PEA)), electron density (N-e) and KERMA relative to air has been computed in the energy range from 1 keV to 20 MeV for some polymers such as nylon, poly-acrylo-nitrile, poly-methyl-acrylate, poly-vinyl-chloride, poly-styrene, synthetic rubber and poly-tetra-fluro-ethylene. The dependence of different parameters on incident photon energy and chemical composition of the selected polymers has been studied. (C) 2010 Elsevier Ltd. All rights reserved.
