| 摘 要： | 提出一种提高辐照食品热释光检测效率的改进技术方法，先采用第1发光曲线筛分样品，再利用发光强度比值对筛分后的6 种待定样品进行鉴定。结果表明：改进热释光方法具有100%检测准确率，而需进行参比剂量辐照及后续热释光测量的样品仅为BS EN 1788-2001方法的33.3%，优选筛分阈值后，这一比例还能进一步降低。改进后的辐射食品热释光检测方法明显提高了检测效率，降低了检测费用，是一种可行方法。

| Abstract: | An improved thermoluminescence method to detect irradiated food was proposed. Food samples were screened
using the first glow curve, and six screened samples were further identified using thermoluminescence glow ratio. Results
showed that the improved thermoluminescence method could achieve 100% detection accuracy, and the samples to be
irradiated with reference dose and measured subsequently accounted for only 33.3% of those to be screened with BS EN
1788 method. Furthermore, this proportion can be further reduced if the high and low thresholds (HT and LT) of screening
were optimized. The improved thermalluminescence method can significantly enhance the efficiency of detection and reduce
the cost and thus is reasonable and feasible. |
