Based on dual-energy X-ray technology combined with forward-scattering

a brand new explosive detection method is presented. Dual-energy technology can give the information on the effective atomic number (Zeff) of an irradiated component

while the intensity of the forward scattered photons can reveal the density information according to our research. Therefore

the existence of the explosive can be effectively identified by combining these two characteristic quantities. Compared with the earlier inspection approaches

the new one has a series of particular advantages

such as high detection rate

low false alarm rate

automatic alarm and so forth. The project is ongoing.
