辐照食品、化妆品包装纸光致发光特性研究

Photostimulated Luminescence Characteristics Research of Irradiated Papers

对食品、化妆品包装用纸辐照后的光致发光特性进行了研究。采用光致发光辐照检测仪对辐照纸张进行检测,结果发现辐照后的各类纸张都有明显的PSL信号升高,这个特征可以用于辐照纸张的鉴定,而且检测过程简单快速。其中杂质多的粗制纸张PSL响应更强,更适合辐照鉴定。辐照纸张的鉴定结果可用于辐照食品、化妆品的间接鉴定。

This article studied the photostimulated luminescence characteristic of irradiated paper. Photostimulated luminescence detector was used to detect the PSL signal of irradiated papers. The results showed that the PSL values of papers would rise after irradiation. This characteristic can be used to indentify the irradiated papers. This method is simple and rapid. The PSL value of crude paper was higher and the crude paper was more fit for the detection of irradiation. This technique is fit for the indirect detection of irradiated foods and cosmetics.
