Abstract
An article irradiation system includes a radiation source for scanning a target region with radiation; a conveyor system including a process conveyor positioned for transporting articles in a given direction through the target region; radiation shielding material defining a chamber containing the radiation source, the target region and a portion of the conveyor system; wherein the radiation source is disposed along an approximately horizontal axis inside a loop defined by a portion of the conveyor system and is adapted for scanning the articles being transported through the target region with radiation scanned in a plane transverse to the given direction of transport by the process conveyor; and an intermediate wall of radiation shielding material positioned within the loop and transverse to the approximately horizontal axis. The intermediate wall supports a ceiling of the chamber, inhibits photons emitted from a beam stop disposed in a given wall from impinging upon at least one other wall of the chamber and restricts flow throughout the chamber of ozone derived in the target region from the radiation source.
