Abstract: In the utilization of nuclear energy and technology, shielding the radiation threat is an important means to control the dose at the site and protect the health of personnel. At present, the main shielding materials include concrete, lead and other alloys and composite materials; Heavy metal oxide glass has both good shielding performance and light transmittance, which is favored in many shielding applications. In recent years, due to the diversity of glass composition types, a large number of new glass development and shielding performance research work have been carried out to further tap its application value. In this paper, the research reports on X/γ ray shielding performance of various heavy metal oxide glasses at home and abroad are combed. Focusing on the acquisition of mass attenuation coefficient parameters, the basic methods, main conclusions, experimental conditions and errors in theoretical calculation, Monte Carlo simulation and experimental measurement are summarized. The common shielding performance characte-ristics and laws of heavy metal oxide glasses are summarized from the perspective of mechanism and data comparison, and the advantages and disadvantages of the three methods and their application value in the actual design and development of glasses are compared. Based on the research literatures of various new shielding glasses, this work discusses and summarizes the reference points and shortcomings in the existing research work, and gives a more comprehensive research idea of X/γ-ray shielding performance of heavy metal oxide glasses, which can provide a meaningful reference for subsequent research.
