Gamma spectrometry is a widely used technique to analyze the gamma-ray emissions of an element. It is also known as gamma spectroscopy or gamma analysis. The process involves measuring the radiation emitted by the nucleus of an atom to determine its elemental composition. Alternatives to gamma spectrometry include neutron activation analysis, X-ray fluorescence, and mass spectrometry. These methods differ in their sample preparation requirements, detection limits, and accuracy. Gamma spectrometry is often used in environmental monitoring, forensic science, and nuclear power generation. It provides valuable information on the sources and concentrations of radioactive isotopes in various materials.
