摘　　要：利用三基色原理进行液体辐射化学剂量学研究。配制不同浓度的酸性湖蓝和弱酸性艳红水溶液,用不同剂量(1.5～13.5 kGy)的γ射线照射。采集被照样品,应用快速色度分析技术测量其三基色量值变化,并进行数据处理分析。结果显示随着试剂浓度及照射剂量的改变,三基色色度出现了明显的规律性变化。其中酸性湖蓝溶液的红色色度值随着辐射剂量增加而逐渐上升,蓝色色度值随着辐射剂量增加而逐渐下降,红色和蓝色色度值呈明显的此消彼长关系,绿色色度变化较小。弱酸性艳红则表现为红色色度随着辐射剂量加大而逐渐下降,绿色色度则随着辐射剂量加大逐渐上升,红色和绿色色度值呈明显的此消彼长关系,蓝色色度变化较小。利用本方法与计算机色度分析技术结合可开展新的化学辐射剂量学研究。Study on radiation dose is based on three primary colors chrominance in chemical solution. Prepare aqueous solution with different concentration Alphaurine A, irradiated by 1.5-15 kGy 60Co γ ray. Data were obtained, from the solution by special instrument which can detect three primary colors information, analyzed and processed, with curves being drawn for the experiment result. The experiment results show three primary colors chrominance in the aqueous solutions changes by different doses 660Co γ-rays and different concentration Alphaurine A. The red chrominance are gradually increasing as the radiation dose is adding, the blue chrominance are gradually decreasing at the same time. The red and blue chrominance changes evidently and trends adversely, green （G） little changed. As for Tracid Brilliant Red B solution, the red chrominance are gradually decreasing as the radiation dose is adding, the green chrominance are gradually increasing at the same time. The red and green chrominance changes evidently and trends adversely. The Red and green changes evidently and trends adversely, the blue chrominance little changed. The experiment demonstrates that radiation dose can be studied based on three primary colors chrominance, and a new method may be developed to measure radiation dose.
