Radiation damage studies were performed on polystyrene based plastic scintillators. Three multi-component systems, each containing two organic fluorescent compounds in a polystyrene matrix, were analyzed. In these systems, p-terphenyl was used as the primary dopant with either dimethyl-POPOP, 3HF, or BBQ as the secondary dopant. In addition, undoped polystyrene samples were also irradiated. Absorbance, fluorescence, and beta excitation measurements were carried out on each sample before, immediately after, and two weeks after irradiation. Radiationinduced absorption in the polymer was detected in the 300-400 nm spectral region. However, no substantial damage was noted in the dopants for scintillator samples irradiated at 10 Mrad.
