How are landmines detected?

A great variety of methods for detecting landmines have been studied. These include electromagnetic methods, one of which (ground penetrating radar) has been employed in tandem with metal detectors. Explosives in landmines can also be detected directly using nuclear quadrupole resonance and neutron probes.

How were landmines used in ww1?

During the First World War, the use of land mines referred primarily to the digging of tunnels beneath enemy trenches and strongpoints, and igniting large charges of explosive.

When was the first landmine used?

Precursors of the weapon are said to have first been used in the American Civil War in the 1800s. But antipersonnel mines were first used on a wide scale in World War II. Since then they have been used in many conflicts, including in the Vietnam War, the Korean War, and the first Gulf War.

Who created the landmine?

General Gabriel J Rains
The first modern land mine was created in the American Civil War. Inspired by simple explosive booby traps, General Gabriel J Rains developed the landmine to defend the positions of the outnumbered Confederate Army at the Battle of Yorktown in 1862.

What is one disadvantage of using an extremely sensitive mine detecting device?

Its main disadvantage is an insufficient sensitivity to effectively detect the sub-kilogram amounts of explosive in the mines. This technique sends radio frequency pulses that excite nitrogen nuclei in the explosive, which induces an electric potential at a receiver coil.

What is the purpose of minefields?

In military science, minefields are considered a defensive or harassing weapon, used to slow the enemy down, to help deny certain terrain to the enemy, to focus enemy movement into kill zones, or to reduce morale by randomly attacking material and personnel.

What is one pollutant can be detected in groundwater using electronic noses?

Trichloroethylene or TCE is one pollutant that can be detected in groundwater using electronic “noses”.
