D-(+)-glucose (Glc) was added to the original Fricke polyvinyl alcoholeglutaraldehydeexylenol orange (FPGX) hydrogel dosimeter system to make a more stable FPGX hydrogelthree-dimensional dosimeter in this paper. Polyvinyl alcohol was used as a substrate,which was combined with Fricke solution. Various concentrations of Glc were tested withlinear relevant fitting for optimal hydrogel production conditions. The effects of variousformulations on the stability and sensitivity of dosimeters were evaluated. The resultsindicated that D-(+)-Glc, as a free radical scavenger, had a great effect on stabilizing thedose response related to absorbency and reducing the auto-oxidization of ferrous ions. Acareful doping with Glc could slow down the color change of the dosimeter before and afterradiation without any effect on the sensitivity of the dosimeter.
