摘要:
The invention provides a security inspection system for inspecting persons, characterized in that it comprises: a passageway which provides an inspection space isolated or partially isolated from an ambient environment, in which at least one sub-passageway allowing persons to be inspected to pass is provided in the inspection space, and each of the sub-passageways is provided with at least one millimeter wave imaging device for millimeter wave imaging of persons being inspected; and an ion mobility spectrometer for ionizing particles of substance or gases that are released or volatilized from the inspected persons into the air in the passageway and then measuring a mobility rate thereof under the action of the electric field to effect identification of substances. At least one radioactive substance inspection device may also be provided in the passageway to detect whether the person being inspected carries radioactive substances.

摘要:
A method and an apparatus for detecting hidden hazardous substance including the steps of: performing terahertz imaging for a detected object; judging whether there is a suspicious area containing the hidden hazardous substance in a terahertz image of the detected object obtained by the terahertz imaging; performing a multi-wavelength spectroscopy measurement to the suspicious area, determining whether the hazardous substance is contained in the suspicious area according to results of multi-wavelength spectroscopy measurement; and outputting the image of the detected object and hazardous substance detecting result. Also disclosed is an apparatus for implementing the method for detecting the hidden hazardous substance according to the present invention. Determination of the hidden hazardous substance can be performed from the perspectives of shape features and substance composition, thus the accuracy of detection is greatly increased.

摘要:
For quarantine treatment of a farming and forestry product for pest control, a method and a device may irradiate logs as a phytosanitary treatment with electron beams. The method may include: spreading the logs; aligning the spread logs to be flush at one end; conveying the spread and flush logs laterally; conveying the logs longitudinally through an irradiation field formed by accelerators to provide treatment of irradiation with the electron beams; throwing the irradiated logs out; and laterally conveying the logs away. The device may include a conveying device for conveying the logs, a shielding structure surrounding the conveying device, and accelerators provided in the conveying path of the conveying device. Two or more accelerators may be provided in centrosymmetry about the conveying path.
摘要:
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.
