    摘要： A method and device for monitoring the position of radioactive materials in vehicles relates to a technical field of monitoring of radioactive materials. The method comprises following steps: powering on a monitoring device, after initializing, the device automatically enters into background mode to acquire and process gamma and neutron detection data so as to obtain and update a background count rate in real time, and an image surveillance system enters into surveillance state; occupancy detector detects that a vehicle enters into monitoring channel, meanwhile the monitoring device automatically enters into occupancy mode, and performs data acquisition process for gamma and neutron detection under the occupancy mode in accordance with the time required by an alarm algorithm, so as to obtain respective total count rates; speed detector detects the times T1 and T2 for the vehicle when it reaches two points with a distance L, and then calculates out the vehicle's speed V; obtaining an alarm threshold by using a special algorithm on the basis of alarming algorithm, particularly, the background count rate updated in real time, and sending an alarm signal when the total count rate exceeds the alarm threshold; transmitting the alarm signal to the image surveillance system via a control interface to notify it of starting to record, meanwhile sending an alarm command to an audio and visual alarm system to inform it of giving out an alarm; with the help of the results of radioactivity detection, speed detection and image capturing, a local computer specifies the position where the radioactive material(s) locate(s) with methods of horizontal and vertical positioning. The present invention can easily and quickly specify the very vehicle and the exact position the radioactive material(s) locate(s) so that the radioactive material(s) can be conveniently isolated and processed subsequently. In this way, time spent on detection has been greatly reduced and lots of human power has been saved.

    摘要： A relocatable container inspection device, which is constituted by modularized units, is used for inspecting a container. The device comprises: a first cabin unit including a radiation source for generating a beam of penetration radiation for penetrating the container to be inspected; a second cabin unit including detectors for detecting the beam of penetration radiation penetrating through the container being inspected and producing corresponding radiographic signals, the second cabin unit and the first cabin unit being arranged oppositely in both sides of an inspection passage; a gantry unit bridging the first cabin unit and the second cabin unit to form a portal-shaped frame adapted for straddling the container being inspected; means for moving the frame relative to the container being inspected along the inspection passage, so that the detectors receive the beam of the penetration radiation generated from the radiation resource and passing through the container being inspected, thereby continuously scanning the container and producing the corresponding radiographic signals, wherein the first cabin unit, the second cabin unit and the gantry unit are all individually made as modular units so as to be quickly and easily assembled and disassembled with each other on the inspection site. In the present invention, all of the modularized units of the container inspection device can be easily assembled and disassembled in the work field, and the dimensions of each modular unit are sized to be suitable for road transports and to be facilitate for the device's movement.
