The physical principles of the gamma nuclear resonance absorptiometry have been laid down quite sometime ago and have been used in many laboratories for studying nuclear structure. In the late eighties and during the nineties it become apparent that gamma nuclear resonance methodology can be implemented for elemental analysis in industrial environment. Specifically extensive work has been published for detection of nitrogen. However, this progress was hampered by lack of intense gamma sources that would interact resonantly with nitrogen. Recent advances in production gamma resonance beams justify revisit of the Gamma Resonance Technology as a viable tool for explosives and drug interception in large cargo containers.
