摘要：
The induced optical absorptions of polymers polystyrene (PS), polymethylmethacrylate (PMMA) and polyvinyl-toluene (PVT), irradiated by neutrons and in gamma fields, were measured for equal doses. The polymers are the most important bases for the use as plastic scintillators. The permanent damage in PS and PVT after recovery in air is larger for neutron than for gamma irradiation. Electron spin resonance measurements (PS, PMMA) of involved radicals gave insight into radical kinetics during the recovery process. Correlations between radicals and optical absorption bands were found. (C) 2003 Elsevier B.V. All rights reserved.
