he use of a new reagent with the capacity of forming colored organo-metallic complexes with metal ions is herein studied for its application in X-Ray dosimetry, aiming to assess its effect on the dose-sensitivity of polymer gel dosimetry. The improvement of the sensitivity of polymeric dosimeters, commonly used to quantitatively register dose distribution in radiotherapy, requires considering both the intrinsic mechanism involved in the irradiation of the dosimetry system (polymerization) and the selected readout technique (e.g. spectroscopy techniques). One of the most used readout methods is measuring the change in the optical density of the dosimeters after their irradiation. The formulation of a new sensitive material able to form organo-metallic complexes and the potentiality of achieving significant changes in the optical density in the irradiated region is studied in this work. For this purpose, a new monomer (GMA-IDA) was synthesized and used in the polymerization with other m
