Gamma-ray spectrometry is a key technique in the study of the decay of radioactive materials. Used by scientists from a wide range of disciplines, problems can be encountered by the inexperienced user because there is a deceptive simplicity in gamma-ray measurements which can hide significant pitfalls. To resolve this situation, the authors of Practical Gamma-Ray Spectrometry have drawn on many years of teaching experience to produce this uniquely practical volume, giving comprehensive coverage of the whole gamma-ray detection and spectrum analysis processes. Discussions of the origin of gamma-rays and the issue of quality assurance in gamma-ray spectrometry are also included. Practical Gamma-Ray Spectrometry is written with the user in mind and has the following benefits:Mathematics are kept to a minimum throughout.No previous knowledge of nuclear matters or instrumentation is assumed.Detectors and their associated electronic systems are discussed.Fault-finding guide ensures that any problems can be sorted out with the minimum of fuss.Practical Gamma-Ray Spectrometry will enable all those involved with radioactivity measurements to get the most from their equipment. It will also be of great value to teachers and students in departments where radioactivity is studied, such as physics, chemistry, environmental biology, archaeometry and radiochemistry.

The original work presented in this thesis constitutes an important contribution to modern Cosmic Ray (CR) physics, and comes during one of the most exciting periods of this field. The first part introduces a new numerical code (DRAGON) to model the CR propagation in our Galaxy. The code is then used to perform a combined analysis of CR data, making it possible to determine their propagation properties with unprecedented accuracy. The second part is dedicated to a theoretical interpretation of the recent crucial experimental results on cosmic electron and positron spectra (PAMELA, Fermi-LAT experiments).  Using the tools developed in the first part of the thesis, the author convincingly argues for the existence of a new spectral component, which could arise either from local astrophysical sources, such as pulsars, or from Dark Matter annihilation or decay. This thesis is a highly advanced work; the methods, analysis and results are clearly and carefully presented.  This work is set to become an important reference document for any future work in this area.
