摘要：Introduction As a kind of high-energy electromagnetic radiation,gamma rays can lead to radiation effect and environmental *** ensure the reliability and safety utilization of gamma radiations in different areas,materials with reliable gamma shielding performances should be *** existing efforts are to use glasses as alternative for the co.ventional radiation shielding *** a typical window material,glass itself has attracted wide attention due to its unique chemical and physical *** them,lead-based radiation shielding materials are widely used in the field of ionizing radiation protection due to their reliable physical *** the nuclear industry and high energy physics laboratories,different materials can be used for temporary or permanent *** lead-based glass doped with heavy metal oxide PbO is widely used in the field of radiation shielding for a long time with reliable light transmission properties,which facilitates the observation and monitoring of radiation *** this paper,three kinds of transparent silicate glass with different PbO co.tents were prepared by a high-temperature melting forming *** gamma-rays protection abilities of the three kinds of glass were investigated through experimental and thermotical *** chemical and thermal stability of the glass were also *** addition,the influence mechanism of the structure and performance differences of the three kinds of glass was also *** Analytical pure quartz sand(SiO_(2),purity 99.5%,in mass,the same below),lead monoxide(PbO,purity 99.0%),potassium nitrate(KNO3,purity 99.0%)and sodium nitrate(NaNO3,purity 99.0%)were selected as raw materials for preparation of three kinds of gamma-rays shielding glass materials by a high-temperature melting *** appropriate amount of raw materials was thoroughly mixed and added to 3 L quartz crucible and heated in air at 1200℃.Then the raw materials were melted at 1250℃for 14
