Photon energy absorption parameters for some polymers

Some photon energy absorption parameters viz. mass energy absorption coefficient (μ/ρ)en, photon energy absorption effective atomic number (ZPEA), electron density (Ne) 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 .
