Gamma radiation induced absorption processes of various scintillating materials were studied at room temperature. Single crystal of PbWO4, Ce-doped YAlO3 and Ce(Pr)-doped Y(Lu)3Al5O 12 were irradiated by 60Co and doses ranging between 1-500 Gy. Broad induced absorption spectra obtained were decomposed into separate Gaussian components and tentatively ascribed to specific color centres. Supporting thermoluminescence and electron paramagnetic resonance experiments were performed to reveal the nature of charge carrier traps. The influence of codoping by aliovalent ions is also shown and discussed.
