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 . The sensitivity of the neutral activation analysis depends on the :

Answer»

neutron flux available for IRRADIATION
availability of nucleus to absorb a neutron
ENERGY of decay process
all of the above are correct

SOLUTION :SENSITIVITY of the nutral activation ANALYSIS depends on neutron flux , availablity of nucleus to absorb neutron and energy of the decay process.
