Abstract

A method for conducting irradiation of all logs of a whole vehicle with X-rays as a phytosanitary treatment may include: connecting a traction device and a goods carrying vehicle outside a shielding door; opening the door; the traction device pulling the vehicle into a tunnel; closing the shielding door; upon the vehicle reaching an irradiation region, accelerators generating X-rays; the traction device pulling the vehicle to pass through the irradiation region; stopping the X-rays; opening the door; the traction device pulling the vehicle away from the irradiation treatment tunnel; and disconnecting the traction device from the vehicle. A device may include a shielding structure, a tunnel formed therethrough; a rail along the tunnel; accelerators within the tunnel; and a traction device for pulling a vehicle carrying goods for quarantine treatment, the accelerators symmetrically arranged at both sides of and on the top of an irradiation region in the tunnel.
