Description
Summary:Accurate determination of absorbed dose is of great importance in every medical application of ionizing radiation, mainly when involving biological tissues. Among different types of dosimeters, the ferrous sulfate chemical solution, known as Fricke solution, can be detached, due to its accuracy, reproducibility and linearity, been used in radiation dosimetry for over 50years. Besides these characteristics, the Fricke Xylenol Gel (FXG), became one of the most known dosimeters for absorbed dose spatial distribution because of its high spatial resolution. In this work, we evaluated the FXG dosimeter taking into account different preparation recipes, in order to characterize its response in terms of absorbed dose range, linearity, sensitivity and fading.
