Patent ID: 7760854

Claim:
A method of conducting irradiation with X-rays as a phytosanitary treatment, comprising: connecting a traction device and a goods carrying vehicle outside a shielding door; opening the shielding door; pulling the vehicle into an irradiation treatment tunnel by the traction device; closing the shielding door subsequent to entry of the vehicle into the irradiation treatment tunnel; upon the vehicle reaching an irradiation region, generating X-rays by accelerators; pulling the vehicle by the traction device so that the vehicle passes through the irradiation region to realize irradiation treatment of the whole vehicle; subsequent to the irradiation treatment of the whole vehicle, stopping the generation of the X-rays; and subsequent to stopping the generation of the X-rays: opening the shielding door; pulling the vehicle away from the irradiation treatment tunnel by the traction device; and disconnecting the traction device from the vehicle; wherein the accelerators are a plurality of accelerators arranged symmetrically at opposite sides and at a top of the irradiation region in the tunnel with respect to a cross section that is perpendicular to a direction in which the vehicle is pulled through the tunnel.
