Neutron detection efficiency of Al2O3:C coated with various thicknesses of Li using OSL

초록

Over recent years, significant developments in OSL have been made regarding radiation dosimetry, age determination, and medical applications. In these applications, Al2O3:C has attracted great interest as the most promising material because of its excellent OSL properties. Although Al2O3:C has a high sensitivity to alpha, beta, and gamma radiation, the material has the disadvantage of insufficiency of sensitivity to neutrons. In this study, we have investigated neutron detection efficiency of Al2O3:C crystal coated with various thicknesses of Li using OSL As a result, the OSL intensity increases as the thickness of Li becomes thicker, up to 7.6 mu m thickness of Li investigated in this study. In addition, we found neutron detection sensitivity was not linearly proportional to the thickness of Li. (C) 2011 Elsevier Ltd. All rights reserved.
