Answer:
The Cf-252 is used as a source of neutrons to excite nitrogen which is commonly found in explosives. The excited nitrogen-15 undergoes radioactive decay by emission of 10.8-MeV gamma rays. The gamma rays are detected and configured by an array of scintillation detectors on three sides of the baggage.
