To detect bombs that may be smuggled into airplanes , the Federal Aviation Administration (FAA) will soon require all major airports in the United States to install thermal neutrons analysers . The thermal neutron analyser will bombared baggage with low-energy neutrons , converting some of the nitrogen -14 nuclei to nitrogen -15 , with simultaneous emission of `gamma` rays . Because nitrogen content is usually high in explosive , detection of a high dosage of `gamma` rays will suggest that a bomb may be present .
