Neutron Activation Analysis
Neutron Activation Analysis (NAA) is a nuclear analytical technique used to determine the elemental composition of a material. It involves the irradiation of a sample with neutrons, which causes the nuclei of certain elements to become radioactive. The resulting gamma radiation emitted by these radioactive nuclei is then measured and used to determine the elemental composition of the sample. NAA is a highly sensitive and accurate technique that can detect trace amounts of elements in a sample, making it useful in a variety of fields including environmental science, archaeology, and forensics.
