摘要: 报道了以高聚物为载体，以有机染料及添加剂为变色指示剂体系，制备一种辐射变色膜。这种辐射变色膜为无色透明固体薄膜，经60Co γ射线辐照后，其颜色变为蓝色。辐照后样品的紫外-可见吸收光谱表明，在可见光区其最强吸收峰出现在624 nm附近。在10～90 kGy的剂量范围内，不含添加剂的辐射变色膜的光密度变化与吸收剂量呈线性关系，而含有添加剂的辐射变色膜对γ射线辐照的响应在50 kGy时就达到饱和。同时还探索了该体系辐照效应的化学反应机理。

Abstract: A new radiochromic film is developed by using a polymer as the base and doping an organic dye and an organic halide. It is a clear transparent solid film, but it becomes blue after irradiated by γ-ray. As shown in the UV-VIS spectrum of irradiated films, the peak in visual region locates about 624 nm, and there is a linear relationship between the net optical density and absorbed dose in dose range from 10 kGy to 90 kGy. The chemical reaction mechanism of the radiation effect on the radiochromic film has also been researched.
