罗布麻茶辐照灭菌工艺中的剂量控制

Dose Control of Irradiation Sterilization for Bluish Dogbane tea

本文给出罗布麻茶灭菌剂量的Ｄ１０值。讨论了产品箱内吸收剂量分布及剂量场空间纵向分布规律。结果表明，罗布麻茶最佳灭菌剂量范围为６～９ＫＧｙ。静态辐照灭菌宜选用水平方向沿等剂量线多层码放，纵向采用不等时多源位辐照处理工艺。可有效地提高产品的剂量均匀性及射线利用率。

In this report ,the D10 dose of irradiation sterilization for bluish dogbane tea was calculated.The dose distribution in z coordinate of radiation field and in tea was studied.The results indicata that the 6～9 KGy dose can kill microorganisms in the bluish dogbane tea with satisfactory efficiency.
