Description

An automated multidetector system for instrumental neutron activation analysis of geological and environmental materials is described. The system was evaluated using NBS SRM's 1632a Coal and 1633a Coal Fly Ash. Data are presented to show the precision, accuracy, and stability of the system over a 3-month period from eight Ge(Li) gamma-ray detectors. As a result of the evaluation, elemental concentrations for Dy, La, Eu, Tb, Yb, Lu, and Ta were determined. These had not been previously assayed in NBS SRM 1633a Coal Fly Ash. The systems were found to have excellent long-term stability which is necessary for the production of high quality data
