ABSTRACT:
For suppressing extraneous radiation from an x-ray type food inspection station enclosure having an entry tunnel and an exit tunnel, two pairs of swinging shield doors are provided, one pair located in the entry tunnel and one pair located in the exit tunnel. In a preferred embodiment, each door is actuated by a dedicated pneumatic door actuator located above the door and placed under control of a microprocessor system that also controls the entire conveyor and x-ray inspection process, in particular closing the doors in the event of a gap in the series of containers that could otherwise allow excessive x-ray leakage from the tunnel. As a fail-safe measure, the shield doors are configured with a slip clutch drive and a mechanical override system that tends to close the doors to maintain x-ray radiation suppression in the event of failure of a door actuator or power source thereof.
