Applications of portable gamma-ray technologies to quantitative measurements in-situ

Generalized-geometry models and methodologies for calibration and assay of nuclear material holdup in process equipment are described. Four important keys to success in satisfying portable measurement needs for inventory of nuclear materials are: improvements in compact, single, rugged, reliable instrumentation for gamma-ray spectroscopy; real-time automation; design and automation of generalized models and methods to satisfy multiple measurements needs; and real-time automation of data acquisition/analysis.
