Non Destructive analysis of objects Using neutron Resonance Capture
In this paper we discuss an analytical method, neutron resonance capture analysis (NRCA), which used the energies of resonances to recognize elements. These resonances are observed by the time-of-flight technique using a pulsed neutron beam at the GELINA facility in Geel (Belgium). The prompt gamma-radiation, emitted after a neutron is captured, is used to signal that capture occured. Areas of resonance peaks are used to evaluate the elemental composition of objects and materials quantitatively. A comparison of NRCA and PGAA is made and elucidated with experimental data resulting from measurements of bronze artefacts at GELINA and at he Budapest neutron Centre.
