Research ArticleOpen accessIn the keywordsEffective Atomic Number of Lead Sodium Borate Glass Systems at 662 keVP. Limkitjaroenporn, W. Chewpraditkul, J. Kaewkhao, S. TuscharoenMass attenuation coefficients of glass systems xPbO: 20Na2O: (80-x)B2O3 (x = 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and 55% mol) were determined at 662 keV photon energy using gamma rays transmission method. The theoretical values of mass attenuation coefficients were calculated by WinXCom program. These coefficients were then used to determine the effective atomic numbers of … …Energy Research Journal, Vol. 2, Issue 1 · 14 Feb 2012 · 8,300 accessesView PDFCite
