Description

Technical Field

[0001] The utility model relates to the technical field of radioactive source transportation, in particular to a new energy transportation tool and a transportation system for radioactive sources. Background Art

[0002] Initially, radioactive sources were transported by ordinary gasoline trucks. These vehicles, without any shielding materials, shielded the gamma rays produced by the radioactive sources solely through the vehicle's main steel structure (generally 1mm thick). This was ineffective, resulting in high environmental dose rates in the vehicle's cockpit and exterior surfaces. The cockpit dose rate exceeded the national standard limit of 20μSv / h, and the vehicle's surface contact dose rate exceeded the national standard limit of 2mSv / h. Subsequently, to ensure that the dose rates in the cockpit and exterior surfaces of transport vehicles met national standard limits, the radioactive source transport vehicles were modified by adding 1mm-2mm thick lead shielding material to the cargo hold, reducing the environmental dose rates in the cockpit and exterior surfaces to below the national standard limits. The cockpit dose rate was generally below 5μSv / h, and the vehicle's surface contact dose rate was generally below 1mSv / h.

[0003] By adding shielding materials, the dose rate of transport vehicles can be reduced, and the radiation hazards to the transport personnel and the environment in which the vehicles are located can be greatly reduced. However, traditional radioactive source transport vehicles use gasoline or diesel as their driving energy. When the gasoline or diesel runs out, the vehicle must drive out of the restricted use area and go to an external gas station for refueling. This situation will cause two adverse effects. On the one hand, the frequency of vehicles leaving the restricted use area increases due to refueling, which increases the probability of radioactive sources being transported out of the restricted use area unplanned, and the risk of radioactive sources getting out of control increases accordingly; on the other hand, radioactive source transport vehicles are all affixed with radioactive warning signs, and the vehicles are generally equipped with warning lights. Frequent vehicles leaving the restricted use area to the outside world will cause public panic and cause unnecessary public opinion trouble.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention and does not constitute any limitation to the present invention. Utility Model Content

[0024] See also Figure 1The present invention provides a new energy transportation tool for radioactive sources, including a new energy vehicle 10 and a shielding device 20. The new energy vehicle 10 is driven by electricity, and the shielding device 20 is installed in the new energy vehicle 10 and stores the radioactive source.

[0025] Specifically, in the embodiments of the present invention, by using an electrically powered new energy vehicle 10 as a means of transporting radioactive sources, compared to conventional fuel-powered vehicles used for transporting radioactive sources, there is no need to refuel. This reduces the number of radioactive source transport vehicles that are driven outside of their designated use areas, i.e., workplaces, thereby reducing the number of radioactive sources and the transport vehicles carrying radiation doses that are not intended for use outside of their designated use areas. More specifically, among the types of electrically powered new energy vehicles 10, options include pure electric vehicles (EVs), which are entirely powered by electricity, and hybrid electric vehicles (HEVs), which combine an internal combustion engine with an electric motor and utilize a combination of electricity and fuel. Compared to hybrid vehicles and conventional fuel-powered vehicles, pure electric vehicles have an optimized powertrain structure, which can reduce vehicle maintenance time, further reducing the number of unplanned uses of radioactive source transport vehicles, thereby reducing the radiation dose risk of radioactive source transport vehicles.

[0026] See also Figure 1 In one embodiment, a new energy vehicle 10 includes a cargo compartment 11 for storing radioactive sources. A shielding device 20 includes a shielding box 21 and shielding material 22. The shielding box 21, containing the radioactive source, is placed within the cargo compartment 11, and the shielding material 22 is attached to the inner wall of the cargo compartment 11. The inner wall of the cargo compartment 11 is configured as six flat surfaces. The shielding material 22 completely covers the inner wall of the cargo compartment 11. The shielding box 21 and the shielding material 22 are made of lead. The thickness of the shielding material 22 is no less than 3 mm.

[0027] Specifically, in the embodiments of the present invention, by using a new energy vehicle 10 with a cargo compartment 11 as a means of transporting radioactive sources, the cargo compartment 11 can be used as a dedicated storage space for the radioactive sources, creating a barrier from the vehicle's passenger compartment and facilitating shielding modifications to the cargo compartment 11. During transport, radioactive sources are typically stored in a dedicated container, such as a shielding box 21. Furthermore, to further reduce the radiation risk posed by the radioactive source, shielding material 22 should be placed within the cargo compartment 11 of the new energy vehicle 10. Depending on the type of radioactive source, for example, for alpha particles, shielding can be achieved with simple materials such as paper or clothing, as alpha particles have very low penetrating power. For beta particles, shielding requires thicker plastic, glass, or lead sheeting. The thickness of the shielding material 22 should be selected based on the intensity of the specific radiation source. For gamma rays and X-rays, lead shielding material 22 is required, as these have high penetrating power. The thickness of the lead sheet should be determined based on the radiation intensity and safety requirements; typically, a thickness of at least several millimeters is required.

[0028] By designating the interior wall of the cargo compartment 11 as six flat, regular spaces, the lead sheeting (22) can be directly installed, completely covering the interior wall of the cargo compartment 11. This effectively shields various types of radioactive sources. Depending on the type of radioactive source used and the range of radiation doses produced, a 3mm thick lead sheet can be selected as the shielding material (22) to meet the required shielding requirements.

[0029] More specifically, in an embodiment of the present invention, during transportation, the radioactive source is placed in a shielding box 21. By setting up two shielding measures of the shielding box 21 and the shielding material 22 in the cargo compartment 11, the radiation dose rate of the vehicle cockpit and the outer surface is greatly reduced. After testing, when three 100Ci Ir-192 radiographic flaw detection sources are placed at the same time, the maximum dose rate in the cockpit is 1μSv / h, and the contact dose rate on the vehicle surface is 100μSV / h, which are far lower than the national standard values, thereby greatly controlling the risk of excessive radiation dose to the transportation personnel and the external environment.

[0030] See also Figure 1 In one embodiment, the new energy vehicle 10 is painted with a warning color, equipped with a warning light 101, and displayed with a radioactive sign 102. By painting the vehicle with the standard warning color for radioactive source transport vehicles, installing the warning light 101, and displaying the conspicuous radioactive sign 102, relevant safety regulations and standards are met, enhancing safety warnings.

[0031] See also Figures 1 to 2 The present invention further provides a radioactive source transportation system, comprising the above-mentioned new energy vehicle 10 and a limited use area of ​​the new energy vehicle 10. The limited use area includes a transportation route area and a parking area of ​​the new energy vehicle 10.

[0032] Specifically, in the embodiment of the present invention, by controlling the transport vehicle of the radioactive source, i.e., the new energy vehicle 10, within a limited use area, a standard transport route area is defined, and the range of the transport vehicle parking area is regulated. This further standardizes and normalizes the use of the radioactive source transport vehicle. More specifically, as shown in the attached Figure 2 The figure shows a bird's-eye view of the workplace where radioactive sources and their transport vehicles are located. The red lines represent the transport routes, and the endpoints of the red lines represent the parking locations. For example, in the workplace represented by the bird's-eye view, the endpoints of the red lines can represent the storage area for radioactive sources and the point of use for radioactive sources, respectively (that is, the parking area for the transport vehicle is only allowed when the radioactive source is transferred between the storage area and the point of use). This further controls the range of movement of the transport vehicle for radioactive sources.

[0033] It should be noted that if the transport vehicle for the radioactive source is an electrically powered new energy vehicle 10, its charging station facilities can be placed within the parking area, further controlling the range of the transport vehicle that is exposed to radiation doses. Furthermore, the higher electrical performance of the new energy vehicle 10 and its own positioning device can be utilized to provide real-time position feedback, further improving the understanding of the area where the radioactive source transport vehicle is located.

[0034] In summary, the utility model provides a new energy transportation tool and transportation system for radioactive sources. By adopting an electric-driven new energy vehicle as a transportation tool for radioactive sources, and stipulating its limited use area, combined with the shielding design on the transportation tool, the radiation dose of the radioactive source is reduced. By charging and replenishing energy in the workplace, the new energy vehicle is prohibited from unplanned driving off the site, thereby reducing the risk of unplanned transportation of radioactive sources off the site.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
