Dosimetric gel is used in several measurements due to its linearity, low cost, and possibility for 3D measurements. This work
brings a new possibility to apply the Fricke Xylenol Gel recipe in the diagnostic measurements region. The Fricke Xilenol
Gel (FXG) dosimeter is associated with the Fe(II) to Fe(III) oxidation, when irradiated, being the final ion concentration
proportional to the absorbed dose. To achieve the scope, the former dosimeter was modified through the benzoic acid addition
in the original recipe forming a new dosimeter, the Benzoic Xylenol Gel (BFXG). The results obtained with this new dosimeter
demonstrated a higher sensibility for low absorbed dose values, bringing down the absorbed dose inferior limit from 0.1 to
0.006 Gy, that is more adequate for radiodiagnostic absorbed dose measurements. This result shows the possibly of BFXG dosimeter
to be used for measurements in the radiodiagnostic region, as for tomography and mammography techniques.
