Portable and versatile X-ray or gamma imaging device for non-destructive examination of suspicious packages, integrating transmission and backscattering imaging. It comprises an X or gamma radiation source (4) adapted to radiography, a large and finely pixelated detector (6) sensitive to X rays or gamma rays adapted to radiography, a removable shielding and collimation accessory (5) to adapt the source to backscattering imaging, a removable accessory (10) comprising a large and finely pixelated coded mask placed in contact with the detector when a backscattering imaging or radioactive source imaging is made, and a synchronised control system (14) for the source, the detector and the latter accessory, and for data acquisition and processing to display an image in real time.
