NAA Provenance
NAA provenance is the use of instrumental neutron activation analysis (INAA) to determine where archaeological ceramics, obsidian, and other materials were made or obtained, by exploiting their high-precision multi-element chemical fingerprints. INAA irradiates a sample with neutrons, making its elements briefly radioactive, and measures the characteristic gamma rays they emit to quantify the concentrations of roughly thirty elements, including many trace and rare-earth elements at very low levels. As Glascock and Neff describe in their account of the technique's role in archaeology, the analytical power of NAA lies less in the measurement itself than in what follows: the statistical formation of compositional groups and the assignment of artifacts to those groups and to geological or production sources. This entry focuses specifically on that provenance application — building compositional groups and attributing artifacts by Mahalanobis distance — rather than on the instrumental measurement in general.
