| Abstract: | A three dimensional Fricke-(PVA-glutaraldehyde)-xylenol orange (FPGX) hydrogel dosimeter was prepared by chemical crosslinking method. Dose determination was performed by measuring the absorbance change of the dosimeter before and after irradiation using UV-Vis spectrophotometer at 585 nm. The dose response of the FPGX hydrogel dosimeter related to absorbance change was linear, when it was irradiated by X-ray in the range of 0～2 Gy.The stability of the dosimeter before and after irradiation was evaluated by studying the change of absorbance with time. |
