Abstract: 

Activators for a radiation-resistant plastic scintillator with increased solubility in polystyrene, tert-butylfluoro derivatives of 3-hydroxyflavone, have been synthesized. A series of plastic scintillators containing up to 3.0 wt. % of the new activators have been obtained. The optical and scintillation properties of the obtained plastic scintillators have been studied, and their radiation hardness has been determined.

Keywords:
