A radiation dose study based on analysis of primary color chrominance

Purpose: The purpose of this study was to assess the possibility of measuring radiation dose based on primary color chrominance in chemical solutions. Methods: We used an aqueous solution with different concentrations of Alphaurine A and Tracid Brilliant Red B. This was irradiated by 1.5–13.5 kGy 60Co γ radiation. Data were collected by an instrument that can detect information on the three primary colors. Data were analyzed and manipulated for each experiment. Results and conclusions: The result shows that three primary colors chrominance in the aqueous solutions change with different doses of 60Co γ-rays and different concentrations of Alphaurine A and Tracid Brilliant Red B. For Alphaurine A, the red chrominance is gradually reduced as a function of radiation dose. The blue chrominance gradually increases concurrently. The red and green chrominance changes obviously and inversely, but the green chrominance changes little. In Tracid Brilliant Red B solution, the red chrominance gradually decreases as th...
