New results on radiation damage studies of plastic scintillators

摘要

This paper presents a comparative study of scintillation and radiation characteristics for a series of new and known plastic scintillators. About 70 new scintillators have been tested. The dose rate effects on some widely used plastic scintillators have been measured. Polystyrene scintillators containing 20% 1-methylnaphthalene + 2% pTP + 0.05% POPOP and 20% 1-methylnaphthalene + 2% pTP + 0.05% POPOP + 0.02% K-27 revealed the maximum radiation resistance about 7-9 Mrad. 18 refs.; 3 figs.; 5 tabs.
