Instrumental neutron activation analysis(INAA)is that the sample is bombarded with neutrons,causing the elements to form radioactive isotopes.It is possible to study spectra of the emissions of the radioactive sample,and determine the concentrations of the elements within it.Neutron activation analysis is a sensitive multi-element analytical technique that used for both Instrumental neutron activation analysis (INAA) is that the sample is bombarded with neutrons, causing the elements to form radioactive isotopes.
