Polystyrene dye doped plastic optical fiber was prepared and used to detect gamma and beta radiation from I₁₅₁ and TeO₄ gamma tracers typically used to get images of tumor areas within the human body. Absorption and fluorescence emission of TMQ, PBDBD365, POPOP styrene doped was performed under gamma and UV-irradiation. The fluorescence efficiency of the binary system PBDBD365-POPOP and the ternary TMQ- PBDBD365-POPOP was compared and according to the experimental results it was shown that the presence of the TMQ dye enhance the fluoresce obtained under I₁₅₁ radiation. Systematic characterization of the binary system was performed as function of primary dye concentration .
