A multidisciplinary reference for forensic scientists, this book consolidates fundamental principles of nuclear forensic analysis, pertinent protocols and procedures, computer modeling development, interpretational insights, and attribution considerations into one convenient source. The authors focus particularly on the chemical, physical, and nuclear aspects associated with the production or interrogation of a radioactive sample. The material is presented with minimal mathematical formality and uses consistent terminology. Principles and techniques are discussed in terms of their applications to real-world investigations and casework conducted over the past several years, providing important insight into the multifaceted changes facing this emerging science.
