Abstract: Radiation defect formation processes in large dimension CsI crystal scintillators have been considered. It is shown that F-centers are efficiently formed in crystals doped with CO32− and OH− ions. Sodium ions harden CsI crystals against radio-chemical reactions of F- centers, and HCO3− ion formation. The use of sodium as a co-activator to increase the radiation stability of CsI (Tl) crystals has been considered.
