<p>An article irradiation system includes a radiation source (10) for scanning a target region (20) with radiation, a conveyor system (12) including a process conveyor (24) positioned for transporting articles in a given direction through the target region (20); radiation shielding material defining a chamber (15) containing the radiation source (10), the target region (20) and a portion of the conveyor system (12); wherein the radiation source (10) is disposed along an approximately horizontal axis inside a loop (26) defined by a portion of the conveyor system (12) and is adapted for scanning the articles being transported through the target region (20) with radiation scanned in a plane transverse to the given direction of transport by the process conveyor (24); and an intermediate wall (16) of radiation shielding material positioned within the loop (26) and transverse to the approximately horizontal axis. The intermediate wall (16) supports a ceiling of the chamber (15), inhibits photons emitted from a beam stop (40) disposed in a given wall (14A) from impinging upon at least one other wall (14C) of the chamber (15) and restricts flow throughout the chamber (15) of ozone derived in the target region (20) from the radiation source (10).</p> |
