针对对玻璃、水晶、树脂 3种眼镜片材料进行了放射性水平监测 ,结果 3种镜片材料的放射性物质含量高低依次为玻璃、树脂、水晶镜片 ;配戴 3种镜片的年照射剂量玻璃镜片显著高于水晶和树脂镜片 ,且有 8 7%的玻璃镜片超过国际上建议的对眼晶体的年照射剂量限值。提示人们在选用镜片材料时要重视镜片中放射性物质的含量 ,以避免长期配戴高剂量放射性物质的镜片对眼晶体造成的损害 The radioactive levels of three kinds of spectacle lens materials, such as glass, crystal and resin, were monitored. The results showed that the content of radioactive substances in the three kinds of lens materials were glass, resin and crystal lens. The annual exposure dose of three kinds of lenses was significantly higher In crystalline and resin lenses, and 87% of the glass lenses exceed the recommended annual dose limit for ocular crystals. Prompt people in the selection of lens materials to pay attention to the content of radioactive material in the lens in order to avoid the long-term wear high doses of radioactive lenses on the lens caused by eye damage
