In this article, we single crystal were grown KBrxCl1-x and KBrxCl1-x:Eu in the laboratory by Czochralski method (CZ). Then cut pieces were exposed under - radiation and their glow curve was investigated. Optical properties of KBrxCl1-x:Eu mixed crystal as a result of Eu heavy element effect determine in UV confine with decreasing F absorption band and formation of Eu+2 stable ones. Also existence of electron trap centers (F) belong to pure host crystal and Eu activation element role is recognized as luminescence center which is effective in sensitivity enhancement of measuring radiation dose by thermoluminescence method.
