Contaminated sites detection
A contaminated site is understood as a defined area of the earth's surface that has been changed by human intervention in a way that is harmful to health or the environment. This can involve, for example, harmful chemical substances as well as war-related contamination, such as unexploded bombs.
For this reason, a survey to detect for contamination is performed at construction sites, normally using geomagnetics. This not only makes it possible to detect unexploded bombs but also ferromagnetic objects, such as buried drums, subterranean tanks, as well as building rubble and other anomalies. In this case, especially the products of the FEREX family are used, which detect changes in the earth's magnetic field due to ferrous parts.
To safely check for suspect objects even at great depths, there is also the option of bore hole evaluation in addition to surface detection. This is used above all when interference signals near the surface do not permit a precise determination. In this case, a FOERSTER probe is lowered into a bore hole on a cable to perform measurements that can be subsequently evaluated using the FEREX DATALINE BM evaluation software.
In 1999, an agreement known as the Ottawa Convention went into effect banning landmines. This treaty regulates the destruction as well as the removal of landmines and requires unaffected states to help affected states with mine clearance.
By November 2015, the convention had been ratified by 162 states. However, thousands of people still die or are critically wounded each year due to exploding landmines. The reason for this is that landmines are still a great danger to the civil population for many years after a war ends, and children in particular are not aware of their danger. In Afghanistan, for example, 10 million landmines are still believed to be buried.
Detecting landmines is a dangerous and difficult task that will still take decades. FOERSTER devices help to search for and detect these landmines. The devices of the MINEX product family have been specially developed to detect explosive ordinance. Even wet or naturally mineralized and conductive ground can be reliably searched with the devices and then cleared. This allows previously mine-infested areas to be resettled or used for agriculture.
In this way, FOERSTER detection devices provide safety again, so that the objective of the Ottawa Convention can be achieved one day: A world without landmines.
