In spite of competing non-nuclear analytical techniques (AAS, ICP-ES, ICP-MS, etc.), reactor neutron activation analysis (NAA) continues to be the most powerful multi-element analytical technique used in geosciences, life sciences, and materials science. Non-destructive NAA, being a technique based on a physical principle different from those of other trace element techniques, should always be used, if feasible, when the need for better quantification of trace elements at ultra-low levels is desirable. In the certification of reference material, NAA as an accurate technique has played and is still playing a key role, even for elements where other techniques have replaced NAA in practical work.
