The purpose of this work was to examine the dosimetric performances of the radiochromic Fricke-Agarose-Xylenol Orange gel by optical measurements in order to perform dose reconstructions, in view of a future development for 3-D maps. Optical images and dose–response curves of the gel were obtained by a CCD-based device, originally designed for reading radiochromic films, that was modified to meet the optical properties of the dosemeter. With a resolution of 0.18 × 0.18 mm the optimum range of doses in which per cent uncertainty is lower than 2% was 3–10 Gy. The minimum detectable dose, estimated as the absorbed dose corresponding to 3 SD above background, was 0.1 Gy. With a resolution of 1.98 × 1.98 mm the optimum range of doses in which per cent uncertainty is lower than 2% was 0.3–10 Gy. The minimum detectable dose, estimated as the absorbed dose corresponding to 3 SD above background, was 0.015 Gy. The comparison with alanine dosemeters in the dose range 7–10 Gy showed agreement within a few per cent and the same agreement was observed for the comparison with TLD in the range 1–3 Gy.
