The database helps improve the quality and quantity of data to make possible the reliable application of prompt-gamma activation analysis (PGAA) in such fields as materials science, geology, mining, archaeology, environment, food analysis and medicine. PGAA is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with delayed gamma-ray emissions. Inaccurate and incomplete data have been a significant hindrance in the qualitative and quantitative analysis of complicated capture-gamma spectra by means of PGAA.
