Resumen

This study aims to evaluate the deviations between actual and estimated values of kinetic parameters obtained by deconvolution fitting of thermoluminescent glow curves, using mathematical models based on various kinetic order approximations and numerical fitting algorithms. By simulating the realistic behavior of thermoluminescent materials under irradiation and heating conditions, and identifying the underlying physical mechanisms, this analysis offers a comprehensive assessment of the accuracy, limitations, and systematic errors associated with different modeling approaches.
