D–T neutron generators as a feasibility tool for landmine detection based on neutron backscattering method

• Detection of landmines was investigated by neutron backscattering method.
• The method was based on using MCNP code and D–T neutron source.
• Uranium was used between source and soil to increase signal-to-noise value.
• Thermal backscattered neutrons were increased up to 2 times greater than background.
• In addition, the effect of soil moisture on the results was studied.

The detection of buried landmines was investigated based on using D–T neutron source and neutron backscattering method. Signal-to-noise ratio – which is the number of backscattered neutrons from the soil containing the explosives respect to the soil without explosives – was calculated using Monte-Carlo N-particle transport code. Different materials were used between the neutron source and soil to increase the signal-to-noise ratio. The results showed that the thermal backscattered neutrons from landmine can be increased up to 2 times greater than the background. In addition, the effect of soil moisture on the results was studied.
