一种染料的辐射脱色与辐射剂量分析

目的:观察在较小剂量γ射线作用导致的染料水溶液脱色与照射剂量的关系。方法:配制不同浓度的弱酸性艳红B染料水溶液,以γ线进行0 Gy~2000 Gy的梯度剂量照射,分别采集样品应用计算机色度分析技术测定记录其三基色色度值变化,进行数据处理,绘图分析,确定实验浓度,继续观察实验样品受温度和时间变化的影响。结果:随着试剂浓度及照射剂量的变化,三基色色度值出现了明显的相应规律性变化,其中红色和绿色色度值呈明确的此消彼长关系,蓝色色度变化不明显,室温环境存放四周时间的试验样本实验数据无明显差异。结论:结果说明0 Gy~2000 Gy的γ射线照射亦可导致与更大剂量致类似的辐射变色规律性变化。

Radiation Dose Effect for Three Primary Colors of Tracid Brilliant Red B

Objective：The study is that radiation dose effects on three primary colors chrominance in tracid brilliant red B solu-tion.Methods：Aqueous solution with different concentration Tracid Brilliant Red B was prepared,irradiated by 0 Gy~2000 Gy 60Co γ ray.The data from the solution was collected by special instrument which can detect three primary colors informa-tion.The experiment result was analyzed,manipulated and drawed curves.Further we observed the irradiated sample was ef-fected by the change of temperature and time.Results：The experiment result show three primary colors chrominance in the aqueous solutions changes by different doses 60Co γ-rays and different concentration Alphaurine A.The red chrominance was gradually decreasing as the radiation dose is adding,the green chrominance was gradually increasing at the same time.The red and green chrominance changed evidently and trended adversely.The blue chrominance little changed.The experimental results had little changes after the irradiated samples preserve four weeks in room temperature environment.Conclusions：The experi-ment demonstrates that 0 Gy~2000 Gy radiation dose can also induced the regular RGB changes similar that in the higher dose.
