Fast Neutron Activation Analysis (FNAA) is based on the detection of the prompt gamma rays that are emitted from the nuclei in a sample following bombardment of the material with high energy (14 MeV) neutrons. The specific isotope of interest is identified both by the energy and the half-life of the observed gamma ray while the concentration of the element is determined by measuring the intensity of the gamma ray at a known point in time after the neutron irradiation of the sample. FNAA is a rapid, non-destructive technique that is used in the analysis of light elements nitrogen and oxygen which are often difficult to determine by other analytical techniques. Because the technique is based upon specific nuclear reactions , the sensitivity of FNAA varies greatly from isotope to isotope. In addition, the sample matrix will also influence the detection limit for an element because of the variations in the background of the gamma ray spectrum.
