Background: Several landmine detection
methods, based on nuclear techniques, have been
suggested during the recent years. Neutron energy
moderation, neutron-induced gamma emission,
neutron and gamma attenuation, and fast neutron
backscattering are nuclear-based methods used for
landmine detection. The aim of this study is to use
backscattered neutron for landmine detection.
Materials and Methods: MCNP code, a well-known
Monte Carlo particle-transport code, was theoretically
used for backscattered neutron counts. An Am-Be
neutron source and a single thermal neutron detector
were experimentally applied to detect the buried
sample. Results: The experimental results obtained in
this way have been in good agreement with the
theoretical results obtained by MCNP. Therefore, the
shield of neutron source plays an important role on
landmine detection. Conclusion: Hydrogenous
material such as polyethylene and boric acid can be
used as suitable shields. They can increase neutron
counts in detector and facilitate detection process.
