Abstract

Radiation damage studies were performed on new polystyrene-based plastic scintillators. Several samples of different multicomponent systems containing new fluorescent compounds were irradiated with a ⁶⁰Co source to a 10 Mrad dose. After irradiation, the samples were annealed for ten days in oxygen and three days in air. Scintillation light output, fluorescence, and transmittance spectra were recorded at three different stages; before irradiation, immediately after irradiation, and after the annealing process. After irradiation and the annealing period, the light output of the best scintillators had decreased by 10% of their original values
