Thermoluminescence (TL) is the thermally stimulated emission of light from  an insulator or semiconductor. The word is a composite from thermo=heat, and luminescence=emission of light.

The thermoluminescent properties of various minerals and ceramics are often used for
     * Archaeological dating
     * Geological dating
     * Radiation dosimetry

Numerical and Practical Exercises in Thermoluminescence

The purpose of this book is to provide a practical guide for both established researchers and for new graduate students entering the field of TL and is intended to be used in conjunction with and as a practical supplement of standard textbooks in the field.

Chapter 1 presents the fundamental mathematical expressions most commonly used for analyzing experimental TL data.

Chapter 2 presents comprehensive examples of TL data analysis for glow curves following first-, second-, and general-order kinetics. Detailed analysis of numerical data is presented by using a variety of methods found in the TL literature.

Chapter 3 presents for the first time in the TL literature detailed numerical examples of several commonly used theoretical models, as well as several comparative studies of analytical expressions used for kinetic analysis of TL data. The main thrust of this chapter is to illustrate how to solve the differential equations describing the traffic of carriers during the various TL processes in the crystal. This chapter presents several theoretical TL models of increasingly complexity using the program Mathematica.

Chapter 4 presents numerical exercises for the TL dose response of dosimetric materials. The models described in this chapter are taken directly from the published TL literature in order to facilitate direct comparison of the results with the original papers. The Mathematica programs are given in a “modular” form consisting of a small core of subroutines performing separate tasks, which can be easily adopted by the readers for a variety of different purposes. A variety of TL models is presented, based on competition during irradiation process, competition during the TL heating process, as well as models containing competition during both irradiation and heating. Numerical examples of how the superlinearity and supralinearity coefficients g(D) and f (D) can be calculated from experimental TL versus dose curves are also given.

Chapter 5 contains a variety of exercises dealing with practical aspects of several phenomena commonly encountered in the study of TL materials. Several exercises deal with the accuracy and reproducibility of measurements performed with TL dosimeters (TLDs). It is shown how the statistical accuracy and reproducibility of TL data can be greatly improved by using individual correction factors for each TLD. Other exercises deal with the phenomenon of thermal quenching and its effects on the measured TL glow curves and on the initial rise technique.
