Radiation inspection equipment, having an inspection state and a transportation state, comprising a radiation detection device and protective walls (3). The radiation detection device comprises a ray source and a detector cooperating with the ray source. In the inspection state, the radiation detection device has an inspection channel (5) through which a subject passes. Each protective wall (3) comprises a plurality of movable wall bodies to make the protective wall (3) deformable. In the inspection state, the protective walls (3) are located on both sides of the inspection channel (5) to prevent radiation leakage. In the transportation state, at least some of the wall bodies of the protective wall (3) are closer to the radiation detection device in the direction of the inspection channel (5) than in the inspection state. High safety is provided during radiation inspection of the radiation inspection equipment in the inspection state, and in the transportation state, the overall transportation of the radiation inspection equipment is facilitated.
