摘要

This study explores the potential of Aluminum Phosphate Framework-41 (AFO) Zeolites for radiation shielding by incorporating heavy elements such as Bi, Pb, and Au into their pores. The composite densities range from 2.68 g/cm3 (AlPO-Gd) to 3.55 g/c m3 (AlPO-41-Pt), with AlPO-41-Pt showing superior γ-ray attenuation, achieving LAC up to 89.404 cm−1 and MAC of 44.37 cm2/g at E = 15 keV. The findings highlight the significant role of structural properties and heavy element doping in enhancing shielding performance, offering promising applications of the frameworks for radiation protection.
