摘要

为探讨判断动态步进辐射加工过程中错步对辐照产品吸收剂量的影响程度，通过不同辐照位影响的实验研究了44个辐照位对模拟产品瓦楞纸的吸收剂量贡献率。结果显示，个别辐照位对模拟产品的吸收剂量贡献极其明显，错步辐照在关键辐照位对吸收剂量影响较大。文章结合工艺特点分析了错步辐照的成因、核查错步辐照的判别条件和预防措施，并给出吸收剂量影响程度的测算公式。

Abstract

In order to determine the effect of misstep irradiation on the absorbed doses of irradiated products in the process with moving shuffle-dwell irradiation system the contribution ratio of absorbed doses had been measured at 44 irradiation location with corrugated paper as model of irradiated products. It has been revealed that the contribution of absorbed doses obviously comes from that at some special irradiation location with the irradiated dummy. And misstep irradiation at special irradiation location has large effect on the total absorbed doses. In this paper the reason, identification and protection of misstep irradiation has been discussed. And the predicated formula of effect on absorbed doses has been given.
