Design and development of composite shielding material for box protective gloves

Abstract

Low-energy radiation is primarily involved in the spent fuel treatment process in a specific nuclear facility, but if it is not shielded, it will still have an impact on worker health. In light of this unique low-energy environment, the Monte Carlo simulation software geant4 is used to simulate and calculate the effect of doping many rare earth elements into glove rubber materials on the shielding effect of low-energy gamma radiation. The results show that some rare earth elements have a good gamma radiation shielding effect, and their chemical toxicity is lower than that of the traditional shielding material lead. This paper demonstrates that selecting rare earth materials for glove box gloves in a suitable energy range is reasonable, and that incorporating suitable rare earth elements into glove materials can improve the energy attenuation rate of composite protective materials. Experiments are used to create the material that can be used to make glove box gloves. The radiation shielding experiment shows that this material's shielding rate to 59.5keV energy can reach 33%~41%, and its other physical properties are good. Based on this finding, we believe that this material can be used to replace lead-containing gloves in some situations and can be used to design related shielding and protective equipment.
