Optically Stimulated Luminescence (OSL) has become the technique of choice for many areas of radiation dosimetry. The technique is finding widespread application in a variety of radiation dosimetry fields, including personal monitoring, environmental monitoring, retrospective dosimetry (including geological dating and accident dosimetry), space dosimetry, and many more. In this book we have attempted to synthesize the major advances in the field, covering both fundamental understanding and the many applications. The latter serve to demonstrate the success and popularity of OSL as a dosimetry method. The book is designed for researchers and radiation dosimetry practitioners alike. It delves into the detailed theory of the process from the point of view of stimulated relaxation phenomena, describing the energy storage and release processes phenomenologically and developing detailed mathematical descriptions to enable a quantitative understanding of the observed phenomena. The various stimulation modes (continuous wave, pulsed, or linear modulation) are introduced and compared. The properties of the most important synthetic OSL materials beginning with the dominant carbon-doped Al2O3, and moving through discussions of other, less-well studied but nevertheless important, or potentially important, materials. The OSL properties of the two most important natural OSL dosimetry material types, namely quartz and feldspars are discussed in depth. The applications chapters deal with the use of OSL in personal, environmental, medical and UV dosimetry, geological dating and retrospective dosimetry (accident dosimetry and dating). Finally the developments in instrumentation that have occurred over the past decade or more are described. The book will find use in those laboratories within academia, national institutes and the private sector where research and applications in radiation dosimetry using luminescence are being conducted. Potential readers include personnel involved in radiation protection practice and research, hospitals, nuclear power stations, radiation clean-up and remediation, food irradiation and materials processing, security monitoring, geological and archaeological dating, luminescence studies of minerals, etc.

Thermoluminescence (TL) and optically stimulated luminescence (OSL) are two of the most important techniques used in radiation dosimetry. They have extensive practical applications in the monitoring of personnel radiation exposure, in medical dosimetry, environmental dosimetry, spacecraft, nuclear reactors, food irradiation etc., and in geological /archaeological dating. Thermally and Optically Stimulated Luminescence: A Simulation Approach describes these phenomena, the relevant theoretical models and their prediction, using both approximations and numerical simulation. The authors concentrate on an alternative approach in which they simulate various experimental situations by numerically solving the relevant coupled differential equations for chosen sets of parameters. Opening with a historical overview and background theory, other chapters cover experimental measurements, dose dependence, dating procedures, trapping parameters, applications, radiophotoluminescence, and effects of ionization density. Designed for practitioners, researchers and graduate students in the field of radiation dosimetry, Thermally and Optically Stimulated Luminescence provides an essential synthesis of the major developments in modeling and numerical simulations of thermally and optically stimulated processes.

In this volume, international leading experts in the study of thermally and optically luminescence give an up-to-date, comprehensive coverage of the theoretical and experimental aspects of these subjects, as well as their applications.The theory of thermoluminescence (TL) and optically stimulated luminescence (OSL) are discussed in detail including mainly solid state models of localized and delocalized transitions. These models cover the effects occurring during the excitation by irradiation and the read-out by heating or by exposure to light. The methods described consist of analytical mathematical considerations as well as numerical simulations.The main application of these effects, namely radiation dosimetry, includes personal and environmental dosimetry, as well as retrospective dosimetry and the dosimetry of cosmic radiation and space missions. Also discussed in detail are archaeological and geological dating, the use of luminescence dosimetry in medical physics as well as general applications in geosciences, other model subjects such as time-resolved luminescence and thermally assisted OSL, and the sister-subject of thermoluminescence in photosynthetic materials.

There is a need to better understand the risks of low level radiation dose in medical diagnostic procedures and ensure that dose measurements are accurate and traceable to National Standards. Users of instruments typically calibrate their dosimeters with one type of radiation beam with a specific photon energy spectrum (referred to as beam quality) and then may use these dosimeters to measure radiation in other types of radiation beam qualities over a different range of photon energies. This is not a problem if the dosimeter response is relatively constant for a broad range of photon energies. However, the response of the optically stimulated luminescent (OSL) dosimeters studied in this work have a relatively strong energy dependence for photons with energies less than 100 keV. Moreover, since this work focused on measuring doses in diagnostic units only, where the mean photon energies are below 100 keV, using a single calibration based on an 80 kVp beam quality as provided by the vendor of the system could result in inaccurate dose measurements. To address this hypothesis, as part of this work, the system was calibrated independently using other beam qualities that better match those of diagnostic units including: RQR50, RQR60, M60, M80 and M100 (Lamperti & O'Brien, 2001), available at the National Institute of Standards and Technology (NIST). A comparison was then made of the air kerma measured by the OSL system using both the vendor's OSL reader calibration and the independent calibration implemented in this work. This comparison shows that when measuring air kerma in x-ray beams with beam qualities that have energy spectra different than the energy spectra of the x-ray beam in which the vendor prepared their calibration set (80 kVp x-ray beam), significant differences of up to 20% are observed. Because of this comparison, a set of beam quality correction factors (BQCF) were developed that allows correcting the air kerma values measured with the vendor's calibrated OSL system, to account for the differences in energy spectra in the air kerma measurement for different beam qualities and ensuring traceability to the national standard for air kerma.
