Abstract
Photon attenuation coefficients in certain tissue equivalent compounds, perspex, polyethylene, polycarbonate and teflon are measured at energies 13.37, 17.44, 22.10, 32.06 and 44.23 keV. Agreement is within a few percent (∼3%) between the theory and experiment, thus supporting the sum or mixture rule to estimate the attenuation coefficients in compounds theoretically from those of the constituent elements approximately. From the measured coefficients the effective atomic numbers for total photon interaction in these compounds are derived. It is noticed that, in general, the effective atomic number decreases as the energy increases.
