Radiation inspection system, comprising a support structure and an enclosure cabinet, wherein - the enclosure cabinet has an infeed opening and an outfeed opening and is internally subdivided into an infeed compartment, an inspection compartment and an outfeed compartment, - a conveyor belt runs in a closed loop around rollers (27, 28, 29, 30) that are supported by a conveyor bed and are held under tension by a tensioning mechanism, - a transport section of the conveyor belt loop serves to transport inspection objects along a transport path through the infeed compartment, the inspection compartment, and the outfeed compartment, - a return section of the conveyor belt loop runs below the transport section from the outfeed opening back to the infeed opening, - a rejection mechanism is arranged in the outfeed compartment and serves to move rejected objects from the conveyor belt into a reject bin which is configured as an expanded portion of the outfeed compartment protruding sideways from the enclosure cabinet laterally to one side of the conveyor belt, - the enclosure cabinet has at least one conveyor access opening with a conveyor access door to allow access for cleaning, servicing and exchanging the conveyor belt, - the enclosure cabinet and the conveyor bed are connected to and supported by the support structure on a rear side of the radiation system which is laterally to one side of the conveyor belt, while the enclosure cabinet and the conveyor bed are clear of the support structure on a front side of the radiation system, which is on the opposite side of the conveyor belt, characterized in that the reject bin and the conveyor access opening are both arranged on the front side, and the reject bin is divided into a reject bin top and a reject bin bottom which are separated from each other along a separation gap, and further that the separation gap is arranged at the level of the transport section of the conveyor belt loop and runs uninterrupted from the outfeed opening to the conveyor access opening which, in turn, runs uninterrupted into the infeed opening so that, after the conveyor access door has been opened and the tensioning mechanism has been released, the conveyor belt can be taken out of the enclosure cabinet by sliding the transport section of the conveyor belt loop out to the front through the separation gap and the conveyor access opening, and by slipping the return section of the conveyor belt loop around the reject bin bottom. - the enclosure cabinet has an infeed opening and an outfeed opening and is internally subdivided into an infeed compartment, an inspection compartment and an outfeed compartment, - a conveyor belt runs in a closed loop around rollers (27, 28, 29, 30) that are supported by a conveyor bed and are held under tension by a tensioning mechanism, - a transport section of the conveyor belt loop serves to transport inspection objects along a transport path through the infeed compartment, the inspection compartment, and the outfeed compartment, - a return section of the conveyor belt loop runs below the transport section from the outfeed opening back to the infeed opening, - a rejection mechanism is arranged in the outfeed compartment and serves to move rejected objects from the conveyor belt into a reject bin which is configured as an expanded portion of the outfeed compartment protruding sideways from the enclosure cabinet laterally to one side of the conveyor belt, - the enclosure cabinet has at least one conveyor access opening with a conveyor access door to allow access for cleaning, servicing and exchanging the conveyor belt, - the enclosure cabinet and the conveyor bed are connected to and supported by the support structure on a rear side of the radiation system which is laterally to one side of the conveyor belt, while the enclosure cabinet and the conveyor bed are clear of the support structure on a front side of the radiation system, which is on the opposite side of the conveyor belt,
