中文摘要：

一种以聚乙烯醇缩聚物为基质，以多芳氨基甲烷类化合物（隐色孔雀绿）为染色物质和卤代物为协同剂制成的辐射变色膜．经电子辐照后其颜色由无色透明变为绿色．辐照后吸收光谱显示其最强吸收峰出现在629nm附近．研究表明：吸光度响应与电子注量成线性关系，电子能量和分次辐照对其有明显影响，在某注量率范围内吸光度存在辐照后效应，24h后趋于稳定，且膜厚与响应成正相关性．该体系辐射变色膜可作为电子柬的辐照变色薄膜剂量计．

英文摘要：

A radiochromic film is prepared by using a polymer as the base and doping an organic dye （Malachite Green） and an organic halide. This radiochromic film is a clear transparent solid film, but it becomes blue after irradiated by electronic irradiation. As shown in the UV-VIS spectrum of irradiated films, the peak in visual region locates about 629 nm. Research shows that. there is a linear relationship between absorbance response and electron fluency. Electronic energy and the continuous irradiation or fractured irradiation make a notable impact on the radiochromic film. The absorbance response have small changes in a range of electron fluency rate. 24 hours after the film stability. The relationship between thickness of radiochromic film and absorbance response is a positive correlation. The radiochromic film can be used as electronic radiation dosimetry.
