摘要

Thermoluminescence and dosimetric characterization of KCl1-xBrx:Eu2+ mixed crystals exposed to beta-ray irradiation have been studied as a function of composition x in the mixed solid solution. Significant changes on its thermoluminescence properties and dosimetric behavior have been found concerning pure end KCl:Eu2+ and KBr:Eu2+ components. The results indicate a minimum thermoluminescence efficiency at about middle composition. The addition of small amount (1.0%) of Br- ion io KCl is more effective in producing a higher thermoluminescence efficiency and lower fading. It also enhances the linear response as a function of irradiation dose increasing greatly its application as an ionizing thermoluminescence dosimeter. (C) 1998 Elsevier Science Ltd.
