Abstract: A mobile radiation inspection apparatus includes a vehicle body, a traveling mechanism, a boom assembly, a first imaging device, and a second imaging device. The boom assembly is mounted on the vehicle body and is configured to switch between an inspection state and a transportation state. The first imaging device includes a first ray source and a first ray detector both mounted on the boom assembly. The first ray source is positioned at the top of an inspection channel. The second imaging device includes a second ray source and a second ray detector. The second ray detector cooperates with the second ray source to detect rays emitted by the second ray source, and the second ray source is positioned on a side surface of the inspection channel. The mobile radiation inspection apparatus implements multi-angle and multi-mode scanning.
