The Atomic Fingerprint: Neutron Activation Analysis

A scientific publication written in the early 1970s. This book explores the principle and applications of neutron activation analysis (NAA), a technique used to determine the concentrations of elements in a variety of materials. It delves into its mechanisms, practical applications in fields such as physics, medicine, criminology, and archaeology, and the sensitivity and accuracy of the methodology. In this informative work, Keisch begins by elucidating the fundamental concepts of neutron activation analysis, explaining how the process relies on neutron bombardment to transform stable isotopes into radioactive ones, thereby enabling analysis through the measurement of emitted gamma rays. The book presents several case studies demonstrating NAA’s utility: from assessing impurities in semiconductors and determining calcium levels in human bones to verifying the authenticity of ancient coins and solving forensic cases with paint samples. Each chapter highlights not only the effectiveness of NAA in yielding precise results but also its role in advancing scientific knowledge across multiple disciplines. The valuable insights provided position NAA as a crucial tool in both contemporary research and practical applications.
