Description of the invention: [Technical field to which the invention pertains] The present invention relates to a surface decontamination apparatus for low micro-radioactive contaminants, and more particularly to a decontamination apparatus which is simple in structure, convenient in operation, and can effectively improve work efficiency. [Prior Art] When the nuclear facility is decommissioned, the storage raft for containing radioactive waste may be exposed to radioactive loose contamination after being removed from the radiation area at the site of the demolition. Before moving into the storage plant, The low-level radioactive contamination of the surface needs to be removed, and the square enters the storage plant. The traditional method of cleaning the surface of the radioactive waste storage device is simpler, and the worker is allowed to squat directly to the side to hide; the smear cloth cleans the pure storage device, and the storage device only has extremely low radioactive pollution, but the long-term health In such an environment, there is still the possibility of a large amount of radiation dose accumulation, causing harm to the human body. The more complete method of art is to directly clean the person wearing protective equipment. Although this method can avoid radiation pollution and harm the human body, the wearing of protective equipment is extremely cumbersome. Miscellaneous, poor work efficiency, and the actual implementation of the financial system; _, how to simplify the process and improve the efficiency of the work in a simple way and at a low cost is an important topic to be considered . In view of the above-mentioned shortcomings of the radioactive waste storage surface of the prior art, the inventors have studied the improvement of these shortcomings, and finally the present invention has been produced. 5 1344155 SUMMARY OF THE INVENTION The main object of the present invention is to provide a low-micro-radioactive soil surface decontamination apparatus that can rely on the overall operating procedure and improve J1 efficiency. Another object of the present invention is to provide a low-reduction legume surface decontamination apparatus which is extremely simple in structure and which can effectively reduce the use cost without cost. In order to achieve the above purpose and effect, the technical means adopted include: a device body having a receiving space at the center of the top side, and a shielding space layer for the storage of the periphery of the receiving space for storage The liquid of the shielding effect is disposed, and the periphery of the shielding space layer is provided with a hollowed-out non-gambling passage to connect the receiving space with the outside; the turntable is disposed on the bottom surface of the receiving space of the apparatus body for The low-micro-radioactive pollutants to be treated are placed and rotated to allow the space to rotate. In order to achieve a more specific understanding of the above objectives, effects and advantages, the following figures are described below. [Embodiment] Referring to the drawings, it can be clearly seen that the present invention mainly includes: a portion of the body i, the turntable 2, and the bracket 3, wherein the center of the core is disposed above the bracket 3 to form The accommodating space 11 is provided in the center of the main body of the device, and a shielding space layer 12 ′ is disposed on the periphery of the accommodating space 且i and the shielding space layer i 2 is thick. Not less than 3 q cm, for storing a suitable amount of liquid with isolation effect (such as water), and in the shielding space layer 2 weeks 6 1344155 ., the edge is provided with a hollow unshielded channel 1 3 'to make the accommodation The space 1 1 is connected to the outside. In addition, at least two pairs of sides of the apparatus body 1 are provided with hooks i 4 so as to be suspended by an external implement (such as a crane or a stacker), and the shielded space layer 1 The bottom side of the 2 is provided with a drain valve 15 for replacing and venting the liquid having the isolation effect therein. The turntable 2 is disposed on the bottom surface of the accommodating space 11 of the apparatus body 1, and the bottom surface thereof is provided with a plurality of rollers 2 1 (or Other devices with reduced friction are allowed to rotate freely. * In actual application, the radioactive waste storage device 4 (usually mostly 5 5 gallon drums) to be treated is inserted into the accommodating space of the device body 1 from the top side and placed on the turntable 2 (in order to effectively improve the space) The accommodating space i 丄 can be a cylindrical shape, and the turntable 2 is also in the shape of a disc. When the worker works, the body is attached to the outside of the shielding space 1 of the device body 1 to The surface of the radioactive waste storage device 4 is cleaned by a hand-held decontamination cloth, and the radioactive waste storage device 4 can be appropriately rotated in the cleaning process towel (the radioactive waste storage device 4 is easily rotated by the turntable 2). The cleaning operation is carried out; and by the secret of the liquid (water) with the isolation effect in the shielding space layer 12, the dose of the worker to be contaminated by radiation can be effectively avoided, and the health and safety thereof can be ensured. ', 'τ, σ above, the low-micro-radioactive surface decontamination device of the present invention can achieve the effect of simplifying the operation procedure and improving the operation efficiency, and is actually a novelty and an invention of the invention. Patent application; however, the above description is only for the preferred embodiment of the present invention, and the variations, modifications, alterations or equivalent replacements of the technical means and Fanming 7 1344155. All of them should fall within the scope of the patent application of the present invention.
