Drawn on many years of teaching experience to produce this uniquely practical volume, issues discussed include the origin of gamma-rays and the issue of quality assurance in gamma-ray spectrometry. This new edition also covers the analysis of decommissioned nuclear plants, computer modelling systems for calibration, uncertainty measurements in QA, and many more topics.Gamma ray spectrometryHandbooks, manuals, etcNuclear physicsGamma ray spectrometryNuclear physics.537.5/352537.5352Gilmore Gordon521184MiAaPQMiAaPQMiAaPQBOOK9910144550403321Practical gamma-ray spectrometry832659UNINA
