标签剂量计是一种在一定的电离辐射下发生颜色明显改变的薄膜标签,可用于目视辨别辐射加工产品是否受过辐照,估计辐射剂量水平,对辐照质量控制具有重要意义。经大量实验与研究,成功研制出一种以聚乙烯醇(PVA)-甲基橙-卤素组分为主要材料的标签剂量计。该标签剂量计在0～25kGy范围内存在一剂量响应突变点,在超过该点的辐射剂量下,标签剂量 Label dosimeter is a kind of thin film label with obvious change of color under certain ionizing radiation. It can be used to visually identify whether the radiation processed product is irradiated or not and estimate the radiation dose level, which is of great significance to the quality control of radiation. After a large number of experiments and studies, successfully developed a polyvinyl alcohol (PVA) - methyl orange - halogen component as the main material of the label dosimeter. The label dosimeter in the range of 0 ~ 25kGy there is a dose response mutation point, at a dose beyond this point, the label dose
