摘要:
目的 观察弱酸性艳红B溶液的辐射脱色剂量学效应。方法 配制不同浓度的弱酸性艳红B溶液,以γ射线进行0~2000Gy的梯度剂量照射,分别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,并确定实验浓度,继续观察实验样本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,三基色色度值出现明显的规律性变化,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4周的样本实验数据无明显差异。结论 将弱酸性艳红B溶液的变色现象与计算机色度分析技术结合可开展新的辐射剂量学研究,该领域尚有很大的完善发展空间。
Abstract:
Objective To study radiation dose effect on three primary colors color value in trac, id brilliant red B solution. Methods Prepare aqueous solution with different eoneentration traeid brilliant red B, irradiated by 0-2000 Gy 60Coγ-ray. Get data from the solution by special instrument which can detect three primary eolors information. Analyze, manipulate, draw eurves for the experiment result. Further preserve the irradiated sample four weeks in room temperature environment and repeat the prnc, ess above. Results The experiment result show three primary colors color value in the aqueous solutions changes by difterent doses 60Coγ-ray. The red color value are gradually decreasing as the radiation dose is adding, the grecn color value are gradually increasing at the same time. The red and grecn color value ehanges evidently and trends adversely. The blue color value little changed. The experimental results have little changes after the irradiated samples preserve four weeks in room temperature environment. Conclusions The experiment demonstrate that radiation dose can be studied based on three primary colors color value, may be it will have more study subject by this methods.
