Abstract: | Pulsed neutron induced activation analysis is a nondestructive technique to detect threats hidden in bulk objects such as
cargo pallets, trucks, etc. Isotopic content of cargo can be measured by counting photons emitted with characteristic energies
as a result of neutron induced reactions within cargo’s materials. Neutron and gamma radiation transport in active interrogation
system consisting of a 14-MeV neutron source, photon detector, and a cargo truck was analyzed with MCNPX code. Gamma ray signatures
of cargo with hidden explosive threat were analyzed during the neutron pulse and between neutron pulses for varying system’s
geometry and material composition of cargo. |
