The Pulsed Fast Neutron Activation (PFNA) method was conceived by Science Applications International Corporation in 1987. It is currently being developed for the non-intrusive detection of explosives, drugs, and other hazardous material in objects of all sizes from luggage to shipping containers. The PFNA method provides identification, quantification and 3-D mapping of elemental components, C, N, O, Cl, Si, most metals, etc. in scanned objects. It uses nanosecond pulsed fast neutrons to induce (n, x{gamma})-process in interrogated luggage and employs inbeam gamma-ray spectrometry to determine the elements and time of flight technique to determine where the elements are present. The principles and experimental data demonstrating the validity of the PFNA method are presented.
