| Abstract: | A scanner system is
presented for pipeline inspection and detection of explosives (landmines). The
portable system detects the type of liquid flowing through the pipe, its
location in land soil and crack position. The method is quite sensitive for
small change (~0.1 g-cm-3) in the density of liquid flowing through the pipe and locating
defect of 1 mm width under insulation. The explosives (landmines) such as TNT
(C7H5N3O6) and RDX (C3H6N6O6)
have density less than that of various types of soils and therefore, a
measurement of density helps to detect the presence of landmine. The explosive
simulating phantom is buried at depth of ~2 cm in soil, so the photons have to
penetrate this much distance before interacting with buried material. The
scattered intensity originating from interactions of photons with the phantom
has the potential to detect the presence of landmine. |
