辐照玻璃光特性在辐照鉴定中的应用

Light Characteristic of Irradiated Glass and It's Application in Irradiation Identification

对钠钙硅玻璃和石英玻璃辐照后的光特性进行了研究。辐照钠钙硅玻璃在400nm处的吸收值和辐照剂量有着良好的线性关系,相关系数达到0.991,该特性使得钠钙硅玻璃片可用于辐照剂量的核查。此外,对辐照玻璃的热释光、光致发光进行了测量,结果显示可以通过测量热释光、光致发光值判定玻璃是否经过辐照,该技术适用于辐照食品和化妆品的间接鉴定。

This article studied the light characteristic of irradiated soda-lime-silica glass and quartz glass. In the absorption spectrum of irradiated soda-lime-silica glass, there was a linear relationship between the absorption value at 400nm and the Irradiation dose. The correlation coefficient（R） was 0.991. This characteristic could be used to check the Irradiation dose. The thermoluminescence and photostimulated luminescence of irradiated glass were measured. Results showed that the value of thermoluminescence and photostimulated luminescence were able to be used to determinate irradiated glass. This technique is fit for the indirect determination of irradiated foods and cosmetics.
