Mapping unexploded bombs (UXO) (old industrial sites, airports) is recommended before starting excavation operations, to execute a scan geophysics in order to put out these items. This way may be highlight areas with high potential risk and eliminate unnecessary risk.
Methods generally accepted in such investigations are vertical magnetic gradient measurements, metal detection, electromagnetic measurement and geo-radar. Experience cumulated in numerous international airports and industrial sites, military and civilian sites compels us to recommend to our customers to execute at least two of such investigations methods.
