摘要

研究了茶叶堆码辐照工艺，测定了产品箱中的辐照吸收剂量、剂量不均匀度，结果表明，对于花蓝结构的辐照装置，必须控制好辐照产品箱的前后翻身，上下对调，不均匀度可控制在μ<2以内。测定分析了茶多酚、氨基酸总量与吸收剂量的关系，提出了茶叶辐照剂量为3—6kGy。

Abstract

The pile-up gamma irradiation techniques for decontamination of tea were conducted using dosimetry measurement of the product cartons irradiated The results indicated that the irradiation could be done with an overdose factor of less than 2 by position changes of the product cartons from the front to the back and from the top to the bottom. Dose effects on the total tea polyphenols and the total amino acids in the irradiated tea were studied. It was found that the optimal irradiation dose for decontamination of the tea was inbetween 3—6kGy.
