Aqueous solutions of different pH from red cabbage (Brassica oleracea L. var. capitata f. rubra DC.) extracts were prepared. Effects of different doses/dose rates of gamma irradiation on the red cabbage aqueous solutions were investigated. Solutions were exposed to 1- 10 kGy of gamma irradiation doses at different rates ranged between 0.42513 to 38.883 kGy/h. The absorbance changes, which are due to gamma irradiation exposures, were determined by a spectrophotometry analysis. Results demonstrate that under gamma irradiation exposure variations (doses and dose rates), the best linearity (R2>0.97) of red cabbage solution extract was at a pH=3.3. Results could be of great importance and obviously indicated the efficacy of a natural red cabbage dye as dosimetric indicators.
