摘要：

The development of efficient gamma-ray shielding materials is crucial for addressing increasingly complex radiation environments. In this study, (BiO) 4 CO 3 (OH) 2 (BCH) and (BiO) 4 CO 3 (OH) 2 @Gd 2 O(CO 3 ) 2 ·H 2 O (BG) fillers were synthesized via a hydrothermal method. After being dispersed into epoxy resin by mechanical stirring, the mixtures were molded using a vacuum-assisted thermal curing process. Under 59.5 keV gamma irradiation, the linear attenuation coefficient (LAC) of BG/EP-50 reached 5.8 cm −1 , representing an 84% increas...
