What Does NAA Stand For?
NAA stands for Neutron Activation Analysis
Neutron Activation Analysis (NAA) is a sensitive analytical technique used to determine the composition of elements in a sample. It involves irradiating the sample with neutrons, causing the elements to form radioactive isotopes. By measuring the gamma radiation emitted as these isotopes decay, NAA can quantitatively identify and analyze trace elements at parts-per-million or even parts-per-billion levels. This method is widely utilized in fields such as environmental science, geology, and nuclear forensics, offering precise and reliable results for various materials.
