辐射加工标签剂量计的初步研究

Study on a New Label Dosimeter for Radiation Processing

摘要: 为了有效监测⁶⁰Co γ射线及电子束参考辐射场中被照产品所受的吸收剂量，本工作研制了一种标签剂量计，用于辐射加工中吸收剂量的快速、简单测量。标签剂量计具有多层复合结构，核心部分是一层辐射变色薄膜，主要成分为聚乙烯醇、酸敏染料和卤素化合物。对该辐射变色薄膜剂量计的剂量学性能进行了分析研究，结果表明，该薄膜剂量计可以满足日常辐照监测的需要。

Abstract: In order to monitor the absorbed dose of goods in ⁶⁰Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film. The radiochromic film contained acid-sensitive dye and halogen compound in polyvinyl alcohol (PVA),and the dosimetry of the film dosimeter was studied, the result showed that the dosimeter was satisfied for daily radiation business.
