摘要
采用聚合变色体系，以类丁二炔单体PCDA为变色染料，制备了一种用于辐照剂量预警的自显色个人剂量计。对基体材料、稀释剂种类、变色染料、溶解温度、成膜厚度以及膜制备工艺进行了研究，建立了自显色个人剂量计制备方法。剂量计接受0.1-2.5 Gy辐照后，颜色从白色变为蓝色，在681.5 nm处测得剂量响应曲线线性相关系数为0.9998，照后两周内稳定性良好，可作为预警式个人剂量计使用。
A self-indicating radiation personal dosimeter was investigated using radiation sensitive material diacetylene monomer PCDA ,which was a component of the polymeri-zation system .The substrate material ,solvent ,sensitive material ,solution tempera-ture ,thickness of film and the preparation method were studied .The dosimeter colour changes from w hite to blue w hen exposed 0.1-2.5 Gy ,and the linearly dependent coeffi-cient of the exposure response is 0.999 8 ,the stability of absorbency in two weeks after exposure is testified well . It can be used as self-indicating radiation alert personal dosimeter .
