Abstract: 

A scintillation material containing mixtures of zinc sulfide powder activated with silver and a neutron converter dicarba-closo-dodecaborane(12) – ZnS:Ag/carborane – was synthesized. Its registration efficiency of thermal neutrons is 49 %. A scintillation element based on the obtained scintillation material was developed. It consists of poly(methyl methacrylate) light guide layers alternating with layers of ZnS:Ag/carborane dispersed in a transparent polymer matrix. The thermal neutron registration efficiency of the created scintillation element is 85 %.
