Abstract
Plastic scintillators in the form of solutions of aromatic compounds in polymers are widely used to record short radiation pulses, as these have luminescence decay times of 10-9-10-8 sec. Ionizing radiation produces singlet and triplet excited states, and also positive and negative ions, which leads to deterioration in the transparency. It is necessary to examine the transparency changes, including the recovery after pulsed irradiation, if the pulse repetition time is short, so the subsequent pulses may be recorded with errors because of the damage to the scintillator. The authors have examined the changes in spectral and integral absorption in scintillators based on polystyrene, poly(methyl methacrylate), and a styrene methyl methacrylate copolymer, which contained various additives; the specimens were exposed to single electron pulses from a 15-MeV linear accelerator.
