Answer #1

In this process the high energy gamma radiation i.e, neutron are allowed to pass through the object to be screened and the detector detects the signal by the amount and intensity of radiation.

Thus, giving a relationship with the radiations passed to the sample and indicating whether the explosive is present or not.

The nuclear resonance absorption involves treatment of object with 9.18 MeV gamma rays which undergoes resonance attenuation in the presence of nitrogen concentration which is detected by a detector.

Neutron + 235U 236U 92Kr + 141Ba
