OSTI ID:786554
This is the third paper in a series on the subject of high accuracy instrumental neutron activation analysis (INAA) using short-half-life activation products. This third paper describes the methods and techniques used to make INAA measurements good to 1 to 3% accuracy (when counting statistics are not limiting) for the certification of 12 elements in a bituminous coal reference material. It is concluded that short-half-life INAA can be effectively utilized for certification quality determinations for many elements. With sufficient care, the variations inherent in a system utilizing rapidly changing radioactives can be understood and controlled, providing accurate analytical results.
