Neutron activation analysis methods use the neutron-induced transient radioactivity or nuclear reactions to obtain information on the elemental composition of samples. These techniques are non-destructive, bulk-representative, applicable to materials where “exotic” elements (such as light elements (H, B, Cl, S), valuable noble metals, rare-earth elements, environmentally-relevant heavy metals) are to be quantified, if the material is not soluble, or where standard reference material are unavailable.
