PHOTON INTERACTION PARAMETERS OF SOME CHEMICAL COMPOUNDS FOUND IN HARD TISSUE

Abstract

Some chemical compounds' photon interaction parameters in hard tissue were investigated by using the (NistXCom)
program in the energy range (1keV-100 GeV). The following interaction parameters are included: mass attenuation
coefficients (μρ), effective atomic number (Zeff), and electron density (Nel). Those are all photon energy absorption
measures by compounds in hard tissue. The Compton effect, the photoelectric effect, and pair creation events are all
phenomena that induce absorption. (Zeff), and (Nel) were calculated using the (μρ) of certain substances in hard tissue.
The parameters of photon interaction values have been explored to see how they alter with energy and hard tissue
constituents. For all photon interactions, the fluctuations of these parameters with energy are graphically shown. We also
estimated the half value thickness (HVT), which agrees with theoretical values for several compounds including Al2O3,
SiO2, and MgO
