Abstract

This work investigated an empirical equation to predict the density of different fluoride glass compositions. The calculated values showed a close match with the theoretical density model proposed by Makishima and Mackenzie (1973), showed strong agreement with the experimental values. The calculations were used some compositional factors including molecular weight, molecular fractions, and the ionic radii of different elements mixed with fluoride, the values of ionic radii derived from "Revised Effective Ionic Radii and Systematic Studies of Interatomic Distances in Halides and Chalcogenides" (Shannon, 1976). In order to theoretically evaluate the radiation shielding properties of fluoride glasses, such as the Mean Free Path (MFP), Half-Value Layer (HVL), Tenth-Value Layer (TVL), Linear Attenuation Coefficient (LAC), and Mass Attenuation Coefficient (MAC), the density value is essential (Inaba and Fujino, 2010).

Keywords- Mass attenuation coefficient, Half-value layer, Mean free path, Molecular weight, Ionic radii.
