利用聚乙烯薄膜辐照变色效应测量^(60)Coγ射线或电子射线剂量

The use of colouring effect of polyethylene film for measuring radiation dose of ^(60)Co γ-rays or electron beams

近年来,辐射化学工业化有了迅速的发展,利用大功率60Co γ辐射源或电子加速器辐照生产性能优越的化工产品逐渐增多,迫切需要快速测量60Co γ射线和电子射线剂量的方法。作者利用聚乙烯薄膜辐照变色效应,研究成功一种可以夹带在辐照物件中,测量106～108rad范围剂量的体系。方法简便,适用可靠。

The change of optical absorption in PE film is observed during irradiation. This effect can be used as a measure of radiation dose of 60Co γ-rays or electron beams at a range of 106-108 rad.
