چکیده انگلیسی
Due to the recent increase in the complexity of external radiotherapy treatments, there is a need for a dosimeter capable of rendering a 3D dose profile to verify the absorbed dose with high spatial resolution. We are developing a solid and moldable 3D dosimeter material with the objective of determining the absorbed dose by measuring its fluorescence instead of the absorbance, which is a more established method. Measuring fluorescence could potentially provide higher sensitivity and spatial resolution, which is critical for 3D dosimetry. In this study, absorbance and fluorescence responses to gamma radiation are presented for doses up to 1Â kGy. Since the material is cured by a photopolymerization process, the effect of the photoinitiator is also analyzed.
