The analytical techniques based on neutron activation are classified according to energy of incoming neutrons, elastic and inelastic neutron scattering, and neutron capture reactions as well as its combination such as thermal NAA (TNAA), epithermal NAA (ENAA), prompt gamma NAA (PGNAA), fast NAA (FNAA), and 14-MeV INAA a form of FNAA based on reactions with 14-MeV neutrons that are produced by neutron generators. These techniques have big application potential since they could provide data about large number of elements simultaneously. **Figure 1** presents more than 65 elements that may be analyzed using neutron activation analysis method. For most elements, NAA is an extremely sensitive method for analysis. The potential benefits of NAA include the multielement capability and the fact that non-destructive analyses can be performed.
