When a nuclear accident occurs, high-energy gamma rays from various radioactive nuclides spread rapidly in the air, not only directly causing harm to the human body, but also indirectly polluting the environment where humans live. Therefore, in order to effectively prevent the hazards of radioactive substances and ensure the safety of people's lives, it is very necessary to quickly and accurately measure the gamma dose rate.

[0003] Fixed gamma dose rate continuous measurement equipment is capable of measuring gamma dose rate. However, this type of equipment needs to be fixed at the measurement point for use, is not portable, and cannot be moved around at will as needed. Mobile gamma dose rate continuous measurement equipment has self-power and automatic networking functions, and can achieve real-time, continuous monitoring of dose rates and gamma nuclide analysis in the deployment area. This type of equipment is mainly used for analysis, identification, dose rate measurement, display and alarm of gamma nuclides in the environment, and is portable. When a nuclear accident occurs, the mobile gamma dose rate continuous measurement equipment can be placed at designated monitoring points using transportation. Alternatively, the mobile gamma dose rate continuous measurement equipment can replace a faulty fixed gamma dose rate continuous measurement equipment as needed.

[0004] There are more and more market demands for mobile gamma dose rate continuous measurement equipment during use. In addition to being portable, mobile gamma dose rate continuous measurement equipment also needs to have display screens, GPS, 4G, WIFI and other modules. It is hoped that solar panels, satellite antennas, and sodium iodide spectrometers can be quickly installed and disassembled on site without tools. At the same time, it is hoped that each module will be as lightweight as possible, so that the equipment can be easier to pack, carry, and transport, and easier to use on site. The solar panels need to be able to adjust their angles so that the solar panels can better face the sun and maximize the power generation of the solar panels.

The following description is made with reference to the accompanying drawings, and unless otherwise indicated, the same reference numerals in different drawings represent the same or similar elements. The schemes described in the following exemplary embodiments do not represent all schemes of the present invention. On the contrary, these schemes are merely examples of systems and methods of various aspects of the present invention involved in the appended claims.

[0034] Figure 1 is a schematic diagram of a dose rate detection system according to an embodiment of the present invention. Figure 2 FIG. 1 is a schematic diagram of the decomposition structure of a dose rate detection system according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the dose rate detection system 100 may include a cabinet assembly 10 and a radiation detection assembly 20 .

[0035] Figure 3 Schematic diagram of a cabinet assembly according to an embodiment of the present invention. Figure 2 and Figure 3 As shown, the cabinet assembly 10 may include a cabinet body 11 and a cabinet door 12. The cabinet body 11 may accommodate components such as a control device and a battery of the dose rate detection system 100. The cabinet door 12 may be pivotally connected to the cabinet body 11 and may close the cabinet body 11. The cabinet assembly 10 may also include a door lock to lock the cabinet door 12 when the cabinet door 12 is closed. A sealing strip may also be provided at the joint between the cabinet body 11 and the cabinet door 12 for waterproof and dustproof sealing.

[0036] Figure 4 is a cross-sectional view of a radiation detection assembly according to an embodiment of the present invention. Figure 5 yes Figure 4 A is an enlarged structural diagram. Figure 2 and Figure 4As shown, the radiation detection assembly 20 may include a housing 21, a base 22, and a radiation detector 23. In some embodiments, the housing 21 may have a cylindrical shape. The radiation detector 23 may be accommodated in the inner cavity of the housing 21. The radiation detector 23 is used to detect the radiation dose rate. In an exemplary embodiment, the radiation detector 23 may be a sodium iodide spectrometer for detecting the dose rate of gamma (γ) rays. In other embodiments, the radiation detector 23 may also be other types of detection instruments for detecting the dose rate of other types of radiation.

[0037] The base 22 can be mounted to the bottom of the housing 21, for example, by bolts. Thus, the radioactivity detector 23 can be located in the space surrounded by the housing 21 and the base 22. In an exemplary embodiment, as shown in FIG. Figure 5 As shown, the base 22 may include a boss portion 221 and a flange portion 222. When the base 22 is connected to the housing 21, the boss portion 221 may extend into the inner cavity of the housing 21, and the flange portion 222 may abut against the axial end of the housing 21.

[0038] According to some embodiments of the present invention, the radiation detection assembly 20 may further include a liner 24. The liner 24 may fill the space between the inner surface of the shell 21 and the outer surface of the radiation detector 23. In an exemplary embodiment, the liner 24 may be made of ethylene-vinyl acetate copolymer (EVA). In other embodiments, the liner 24 may also be made of other foam plastics, such as polyvinyl chloride (PVC), polystyrene (PS), polyethylene (PE), phenolic resin (PF), polyurethane (PUR), etc. In an exemplary embodiment, the liner 24 has an inner hole to accommodate the radiation detector 23, and the shape of the inner hole is adapted to the outer contour of the radiation detector 23.

In an exemplary embodiment, the sealing ring 26 can be located between the radial surfaces of the housing 21 and the base 22, for example, between the radial inner surface of the housing 21 and the radial outer surface of the base 22. In an exemplary embodiment, the boss portion 221 can include a groove on its radial outer surface to accommodate the sealing ring 26. When the base 22 is connected to the housing 21, the sealing ring 26 can be squeezed by the housing 21 and the base 22 in the groove, thereby generating a sealing effect. By arranging two sealing rings 25 and 26 at different positions, the radioactive detection assembly 20 can reach the dust and water resistance standard of IP67 level.
