Tropical soils impede landmine detection

Use of a metal detector is the most common technique when searching for landmines, which litter the soil in approximately 90 countries around the world. Many of these countries are located in the tropics where intensively weathered soils are prevalent. These tropical soils have certain properties that can limit the performance of metal detectors due to soil magnetic susceptibility. This problem is enhanced by the spread of minimum-metal mines.
