Test results of the optical and scintillation properties of low-cost scinti
llators based on widely produced oil-refinery products are presented. Under
excitation with high-energy particles, the best specimens of the scintilla
tors showed luminescence decay times of 6.3-8.9 ns and light outputs of 80-
90% that of a benchmark polystyrene scintillator containing 2% pTP + 0.05%
POPOP.
