Abstract
Radiation defect formation processes in large dimension CsI crystal scintil lators have been considered. It is shown that F-centers are efficiently for med in crystals doped with CO32- and OH- ions. Sodium ions harden CsI cryst als against radio-chemical reactions of F-centers, and HCO, ion formation. The use of sodium as a co-activator to increase the radiation stability of CsI(Tl) crystals has been considered. (C) 2001 Elsevier Science Ltd. All ri ghts reserved.
