INSTRUCTIONS: [Technical Field] The present invention relates to a low-micro-radioactive surface decontamination device, and more particularly to a decontamination device which is simple in structure, convenient in operation, and can effectively improve work efficiency. [Prior Art] When the nuclear facility is decommissioned, the storage device for the radioactive waste may be exposed to radioactive loose contamination after being removed from the high-radiation area of the decommissioning site. The dumping of the noodles can be removed to enter the storage plant. The traditional method of cleaning the surface of the radioactive waste storage device is simpler, and the worker is placed in the side of the tenderness to clean the bribes. Although the lack of the storage device has only a very low level of happiness (4), Under the _ environment, there may still be a large amount of radiation dose accumulation, causing harm to the human body. It is a fine turn to prevent the staff of Wei Bei from cleaning directly. Although this method can avoid the smuggling of the smear, it is cumbersome, and the Meihe slave has the inconvenience and lack of practical application; therefore, how to cost effectively Simplify the operating procedures, improve work efficiency, and the important issues to be considered. h The hand is a disadvantage. In view of the radioactive waste storage and disposal table of the prior art, the inventors have researched and improved the way to improve these defects. 200908019 SUMMARY OF THE INVENTION The main object of the present invention is to provide a surface decontamination device for low micro-radioactive pollutants, which can effectively simplify the overall operation procedure and improve work efficiency. Another object of the present invention is to provide a surface decontamination apparatus for low micro-radioactive contaminants, which is extremely simple in structure, does not require excessive cost, and can effectively reduce the use cost. In order to achieve the above purpose and effect, the technical means adopted include: a central body provided with a top side opening σ accommodating space, and at the periphery of the accommodating space, the ring has a shielding space layer to Providing a liquid with a separating effect, and a peripheral wall of the shielding space layer is provided with a hollow non-shielding passage to connect the accommodating space with the outside, and a turntable is disposed on the bottom surface of the accommodating space of the device body to It is used to hold the low micro-radioactive stain to be treated and to enable it to rotate in the accommodating space. In order to obtain a more specific understanding of the above objects, effects and features of the present invention, the following drawings are described below. [Embodiment] As shown in the drawings, it is apparent that the present invention mainly includes: a device body, a turntable 2, and a wire 3, wherein the device body 1 is disposed above the bracket 3 to form a In the center of the main body of the device, a receiving space 11 is provided in the center of the main body, and a shielding intervening layer 12 is disposed on the periphery of the receiving space i, and the thickness of the shielding space layer 12 is Not less than 3 〇 cm for storing a suitable amount of liquid with isolation effect (such as water), and in the shielding space layer 丄 2 weeks 200908019 rim does not have a hollow unobstructed passage 13 'to make the accommodating space 11 Externally connected, and at least two pairs of sides of the apparatus body i are provided with hooks ,4, = will be suspended by an external implement (such as a crane or a stacker), and the bottom side of the shielded space layer j 2 It is provided with a drain valve χ 5, which can be replaced with a liquid with a separating effect. The turntable 2 is arranged on the bottom surface of the accommodating space of the device body 1 and has a plurality of rollers 2 1 (or other A device that reduces friction) to allow it to rotate. When applied by Becker, the radioactive waste storage device 4 to be processed (the 5-55 gallon bucket for Tongyuxi) is the space for the top side of the body i to be placed on the turntable 2 ( In order to effectively improve the space utilization efficiency, the accommodating space 丄1 can be a cylindrical shape, and the turntable 2 is also in the shape of a disc-shaped disk. When the worker works, the body is attached to the leg of the device body i. 2 phase, the decontamination cloth cleans the surface of the radioactive waste storage device 4, and during the cleaning process, it can be appropriately transferred: the radioactive waste storage device 4 (small scale 2 material _ sexual waste sin storage device 4 threat Rotate), when cleaning (4); shouting _ shielding space, 12 isolation of liquid (water) isolation, can effectively avoid the staff of the radiation (four) dose, _ its health and safety. , go, > 1X_L said 'this hair-like weaving and splicing button ^ dyeing wire decontamination device does go into the process of scaling the scale, improve the effect of the touch rate, it is - novelty and similar invention, green Fati (4) Please invent the invention; however, the contents of the above-mentioned outlines are only for the remuneration of the book, and the changes, modifications, alterations or equivalent replacements extended by the technical means of the invention and Fan threat 200908019 are also It is intended to fall within the scope of the patent application of the present invention.
