ANALYTICAL STUDY OF THERMOLUMINESCENCE GLOW CURVES FOR LUMINESCENT DOSIMETRIC MATERIALS.

Abstract

This study is divided into two parts: the first one is to analytically study the analysis of the data obtained from thermoluminescent materials (glow curves), and the second part is to investigate the thermoluminescence (TL) dosimetric properties of phosphate glass samples doped with different concentrations of Lanthanum (La). There exist many methods to analyze TL glow curves. However, the Computerized Glow Curve Deconvolution (CGCD) method is the most popular used. Despite its success, this method has some theoretical, mathematical, and computational problems. These problems pose a limit and precautions to the usage of CGCD in the field of thermoluminescence dosimetry (TLD). Thus, the first part of this study attempts to discuss and suggest new solutions to the computational problem. Some TL theoretical models and the kinetic parameters evaluation methods are also presented.
