Calculation of effective atomic and electronic numbers of glasses absorbing x or γ ray

In this thesis, mass attenuation coefficient, effective atomic and electronic number of glasses containing PbO, BaO, Bi2O3, SiO2, B2O3 were calculated at 1 keV-1 GeV. SiO2 and B2O3 were planned as glass former; PbO, BaO, Bi2O3 were planned powerful absorber of photon radiation. Atomic and electronic cross sections, effective atomic and electronic number of glasses were calculated by using mass attenuation coefficients which were obtained from WinXCom computer program. At first section, some results of glasses of silicium and boron were graphed at 1 keV-1 GeV. While ratio of heavy metal oxide are increased in glass; it is indicated that mass attenuation coefficient, effective atomic number of glasses increased, but effective electronic number differantiate depend on energy range. Although having same ratio PbO and Bi2O3 glasses gives nearly same results, BaO glasses generally shows less radiation absorbtion At second section, calculated experimental results which are using mass attenuation coefficients obtained from literature and theoretical results of those glasses are tabulated for 662 keV. Moreover theoretical data of those glasses were compared with data of Direct-Zeff computer program. Theoretical and empirical values of mass attenuation coefficient, effective atomic and electronic number at graphics were found to display linearity or did not depend on increasing ratios of heavy metal oxide. While effective atomic number of glasses shows theoretical and experimental linear correlation with heavy metal oxide ratio, mass attenuation coefficient and effective atomic number of glasses indicates only theoretical linearity. That unlinearity may be due to amorf structure of glass. At last section, mass attenuation coefficients, effective atomic and electronic numbers of various glasses obtained by some producers were calculated and graphed.
