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), element- või isotoop-analüüsi liik, mis põhineb aktiveeritud proovides sisalduvate nukliidide kiirguse mõõtmisel
