One essential characteristic of life is the exchange of matter and energy between organisms and their environment. Radiation is a form of energy that has always been around in nature and will forever be the companion of human beings throughout life. In order to assess the impact of radiation exposures properly, it is essential to introduce appropriate quantities and units which can then be used for quantification of exposures from various sources. In principle, radiation protection is mainly aimed at controlling radiation exposure, while radiation dosimetry deals primarily with the measurement of relevant radiation quantities especially doses. This book is divided into two parts. The first contains up-to-date definitions of the most significant radiation quantities including their interpretation. In the second part, the exposures of both individuals and population at large to various types of natural and man-made sources are compared and discussed. The concept of quantities and units as well as analysis of exposure due to various sources in our environment is based on the latest, highly regarded authentic sources such as ICRU, ICRP, IAEA and particularly UNSCEAR reports and recommendations. The material reflects the latest review of the current terminology in radiation protection dosimetry and the contemporary assessment of radiation exposures of the population, radiation workers and patients.

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 dosimeters 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.
