Description

An analytical instrument used to qualitatively and quantitatively determine the elemental content of materials. Neutron activation analysis (NAA) uses a neutron source, such as a reactor or an accelerator, to irradiate the sample. Elements in the sample become radioactive and emit gamma rays as they decay. The wavelengths and intensity of the decay processes are measured with a spectrometer to determine the types and amounts of elements present. NAA is good for trace elemental analysis since detection limits are in parts per million. It has been used for provenancing stones (Aston et al 2000) and characterizing glass (Sayre and Smith 1961).
