Abstract
Aqueous solutions of the organic dye Rhodamine B were found to be useful in measuring radiation doses in the range 0.1-2 kGy. Either spectrophotometric or spectrofluorometric measurements can be used. The dosimeter readout is unchanged for at least 60 days after irradiation if the solution is kept in the dark at room temperature. Effects of pH and the dye concentration on the dosimeter response were investigated. Radiation chemical yield and fluorescence quantum yield were also calculated.Entities:
