| 摘 要： | 采用测定辐照产品箱中吸收剂量不均匀度的方法对5种常用辐照产品的3种辐照加工工艺质量进行了研究。结果如下：1）上下对调并前后翻转的双面辐照工艺，其产品箱中的吸收剂量不均匀度U范围为1．36－1．67，在辐照加工质量控制标准（U＜2）以内，可用于生产。2）单面辐照方式其剂量不均匀度为2．67，超过了质量控制标准，不宜采用。3）后排单面辐照方式其剂量不均匀度（2种产品）分别为3．25和3．69，远大于U＜2的标准，不宜作为主要辐照方式，但可以作为辅助辐照方式以提高^60Co源的利用率。

| Abstract: | The quality of three irradiation techniques for five irradiated products has been studied using the measurement of dose ununiformity in product box irradiated The results were as follows:1) The range of dose ununiformity was from 1 36 to 1 67 with changing the position from the top to the bottom and from the front to the back and it didn't exceeded the dose ununiformity limitation (U<2) This technique can been used to production 2) The dose ununiformity of single face irradiation was 2 67 It exceeded the limitation described, so which can not be used to production 3) The dose ununiformity of single face irradiation in the back rank (two products) were 3 25 and 3 69 respectively, also exceeded the limitation described and can not be used to production But it can be used as assistant irradiation method for increasing the utilization efficiency of 60 Co |
