Abstract

The work consists in evaluating the photosensitivity of Fricke solution modified by addition of dyes acting as a photosensitizers, comparing the behavior of FAM dosimeters (Fricke solution modified by addition of methylene blue) and FAT (Fricke solution modified by addition of toluidine blue) after irradiation with LED in acrylic phantom. An arrangement of LED, prepared for this purpose and a set of commercially available LED were used for irradiation the samples, as well as an acrylic phantom. The results show that the FAM is more sensitive dosimeter than FAT; samples irradiated with LED demonstrated the sensitivity of the dosimeters to red and blue light obtaining calibration curves with good correlation coefficients, so that these dosimeters may be used in the future for photodynamic therapy dosimetry.
