Abstract

The development of radiochromic indicator labels has recently become a fascinating research topic. In this experiment, carmoisine was used as a dye for paper indicator labels. This label was prepared by immersing paper in the carmoisine dye solution which has pH 2.0, 7.4 and 9.0. The prepared label was tested using a Co-60 source for doses of 5 to 100 kGy. The label's color stability was observed for 45 days. The labels color became more faded with increasing doses. The optical density and gray values increased linearly with increasing doses. The label color showed good stability for 45-day shelf life.
