Unraveling Thermoluminescence by C M Sunta Pdf

The book is essentially about the theoretical aspects of thermoluminescence (TL). It is structured and written in a manner which will specially be of interest to the fresh undergraduate students and young researchers planning to take up work in the field of thermoluminescence. It is arranged into seven chapters, starting with the historical growth of the subject of TL and an overview of the luminescence phenomena. A Physical model involving thermally disconnected deep traps is specially described. Using this model expressions are derived for the TL intensity growth curve, the supralinearity factor and the pre-dose sensitization factor. A new factor, called the sensitization factor is introduced which co-relates the supralinearity and the pre-dose sensitization factors. Dealing with the theoretical models of TL, limitations of the general order (GO) kinetics and the mixed order kinetics models are specially brought out. Due to the lacunae of GO model the determination of activation energy becomes subject to error, when GO model is applied to the experimental TL glow curves. Satisfying the quasi-equilibrium (QE) condition is essential for the validity of analytical models of TL. A new method is given to ascertain if QE condition is satisfied in an experimental glow curve. The book assumes a basic knowledge of physics and mathematics at an undergraduate level and takes the reader to the results at the cutting edge of understanding of the subject in an easy to understand manner.

Theory Of Thermoluminescence And Related Phenomena by Reuven Chen,Stephen W S Mckeever Pdf

In this book, the authors give an up-to-date account of thermoluminescence (TL) and other thermally stimulated phenomena. Although most recent experimental results of TL in different materials are described in some detail, the main emphasis in the present book is on general processes, and the approach is more theoretical. Thus the details of the possible processes which can take place during the excitation of the sample, and during its heating, are carefully analysed. The methods for analysing TL glow curves are critically discussed, and recommendations as to their application are made. Also discussed is the expected behavior of these phenomena as functions of the experimental parameters, for example, dose of excitation. The consequences of the main applications of TL (for example, radiation dosimetry) are also discussed in detail as are the similarities and dissimilarities of other thermally stimulated phenomena, and the simultaneous measurements of the latter and TL.

Handbook of Thermoluminescence by Claudio Furetta Pdf

This second edition of the Handbook of Thermoluminescence enlarges on all the subjects which were treated in the first edition and adds further arguments, including the theory of thermoluminescent dose measurement, several examples concerning the kinetics parameters determination using various methods such as peak shape, isothermal decay, and so on. A special section is devoted to food irradiation, an important subject at the present time, and to the thermoluminescent characterization of the minerals extracted from the irradiated food. Another new section is devoted to the thermoluminescent phosphors and their main characteristics. The analytical treatments of the various thermoluminescent models are fully developed. As in the first edition, the arguments are given in alphabetical order to ease research. This second edition therefore aims to provide real practical support for researchers, students and personnel involved in radiation protection services, as well as in medical applications.

Thermoluminescence of Solids by S. W. S. McKeever Pdf

McKeever gives us a comprehensive survey of thermoluminescence, an important, versatile, and widely used experimental technique. Bringing together previously isolated specialized approaches, he stresses the importance of the solid state aspects of the phenomenon. The book contains chapters on analysis and special properties, on instrumentation, and on the variety of defect reaction - using the alkali halides and SiO2 as examples - that can take place within a material to yield thermoluminescence. Three chapters concerning applications discuss the features of the solid state reactions to expain some of the properties observed in practice.

Questions and Answers on Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL) by C. Furetta Pdf

Currently, thermoluminescence (TL) and optically stimulated luminescence (OSL) are the main techniques for studying the luminescence properties of several materials, mainly insulators called phosphors. Frequently, however, students and experts alike need to clarify some concepts related to the effects and defects present in the radiation interaction with solids generated by these phenomena. In this book, a series of questions and corresponding answers give a clearer explanation about the concepts, theory and models related to TL and OSL, including applications in important related areas.Students, researchers and teachers will find this book a good guide for understanding TL and OSL as methods for studying the nature of luminescent solids. It provides a quick way for clearing doubts in the concepts and terminology concerning OSL and TL, as it is intended to answer many questions which can be encountered in practical applications.

Operational Thermoluminescence Dosimetry by Claudio Furetta,Pao-Shan Weng Pdf

This book provides a comprehensive description of a dosimetric technique called thermoluminescence dosimetry. There are hundreds of scientific papers on thermoluminescence and its applications, but none deal with the "handling" of the technique, except for some official documents regarding procedural tests which are now not easily found. For this reason the authors have written this book with the aim of describing in detail how to use this dosimetric method. This volume is a valuable guide not only on the proper handling of the TL dozemeters but also on the results obtained by their use. The book consists of nine chapters. The first three chapters cover the theory of thermoluminescence and the experimental methods used to evaluate the kinetics parameters. The next three chapters describe the practical aspects of setting up a thermoluminescent dosimetric system, specifically suggesting the procedures to be used in handling the TL dosimeters as well as all the related instrumentation. The algorithm correlating the TL emission to the radiation dosage is provided and explained. The precision and accuracy of the TL measurements are also discussed. The last three chapters are devoted to: (i) the practical procedure used in some specific application fields, (ii) a discussion about the lower limit of detection and (iii) the TL instrumentation. Several practical illustrative examples are given throughout the text. The book is intended for students and researchers learning new techniques and those working in the area of radiation dosimetry with a specific interest in the TL technique.

Unraveling Piltdown by John Evangelist Walsh Pdf

In 1913 amateur fossil hunter and archaeologist Charles Dawson found in a gravel pit the cranium and jaw of an entirely new species of humanoid, which became known as Piltdown man, which caused headlines worldwide as the missing link between man and ape. In 1952, it was exposed as a hoax. With eight pages of photos, this book is a wonderful detective story, and the first examination the convincingly fingers the perpetrator.
