FIELD: physics.SUBSTANCE: cargo (2) is illuminated with X-ray radiation with a first spectrum and the atomic number class to which the material in said cargo belongs is determined via high-energy differentiation. Furthermore, ?-radiation or neutron radiation, spontaneously emitted by the cargo is measured; the class of the spontaneous ?-radiation and/or neutron radiation of the material in the cargo is determined based on measurement of the spontaneous radiation and the class of the significance of the material of the cargo is determined based on the determined atomic number class and spontaneous radiation class.EFFECT: enabling highly reliable detection of suspicious objects with a high atomic number.14 cl, 4 dwg |
