Landmine detection method combined with backscattering neutrons and capture γ-rays from hydrogen.

The usefulness of the measurements of the backscattering neutron and 2.22MeV capture γ-ray from hydrogen in the landmine detection method is described in this paper. When the soil moisture content is increased, the reaction rates of both the neutron scattering reaction and capture reaction are increased.

Development of landmine detection system based on the measurement of radiation from landmines.

For the detection of landmines, a new gamma-ray detector system, a neutron source, and control and measurement devices were developed. A prototype system has newly been developed by combining these devices. The usefulness of capture gamma-ray and backscattering neutron methods is examined with real explosives in several conditions and the performance of the prototype landmine detection system is demonstrated experimentally in this study.
