This paper investigates the theoretical properties of a novel series of phosphate glasses
with potential applications in radiation shielding, characterized by the composition (60-x)
P2O5-xWO3-10ZnO-10ZrO2-20CeO2, where x is varied at 0%, 15%, 30% and 60% by
weight. Through applying the EpiXS computational code, we explore the effects of
tungsten trioxide (WO3) substitution on the physical properties of the glasses, focusing on
the density and radiation attenuation efficiency. The study reveals that increasing the WO3
content substantially enhances the glass density from 3.18 to 4.34 g/cm3, correlating
directly with improved gamma-ray shielding effectiveness. Our findings indicate that the
strategic incorporation of WO3 into phosphate glass matrices can lead to materials with
optimal characteristics for radiation protection, providing a balance between high atomic
weight elements and the desirable features of zinc oxide (ZnO) and zirconium dioxide
(ZrO2). This study underscores eco-friendly and cost-effective alternatives to conventional
lead-based shields, and the potential of these innovative phosphate glasses in advancing
radiation shielding technology, thus highlighting the opportunities for future experimental
validations and applications in diverse fields such as nuclear energy, medical radiology,
and the aerospace industries. By providing a deeper understanding of the underlying
mechanisms that govern radiation interaction with these materials, this research
contributes to the development of safer and more efficient shielding solutions, marking a
step forward in the design of next-generation radiation protection materials.
