Title: activation analysis Long Title: IUPAC Gold Book - activation analysis DOI: 10.1351/goldbook.A00096 Status: current Definition A kind of elemental or isotopic analysis based on the measurement of characteristic radiation from nuclides formed directly or indirectly by activation of the test portion. In general, a specification is added of the type of the incident radiation (e.g. neutron, photon) and its energy (e.g. thermal, fast).
