Abstract :
A calibration method has been studied for attaining, with good precision, absolute measurements of the spatial distribution of the absorbed dose by means of the Fricke gelatin xylenol orange dosimetric system. With this aim, the dose response to subsequent irradiations was analyzed. In fact, the studied modality is based on a pre-irradiation of each single dosimeter in a uniform field with a known dose, in order to extrapolate a calibration image for a subsequent non-uniform irradiation with an unknown dose to be measured.
