A snapshot backscatter radiography (SBR) system and related method includes at least one penetrating radiation source, and at least one radiation detector. The radiation detector is interposed between an object to be interrogated and the radiation source. The radiation detector transmits a portion of the forward radiation from the radiation source to the object. A portion of the transmitted radiation is scattered by the object and is detected by the detector. An image of the object can be obtained by subtracting the forward radiation detected at the detector, or an estimate thereof, from a total of all radiation detected by the detector. Integrated circuit inspection, land mine detection, and luggage or cargo screening systems can be SBR based.
