However, the dehydrated residual waste still has radioactivity, but the radiation shielding capability of the high-density polyethylene is poor, so that the radiation of the dehydrated residual waste can be transmitted to the outside through the container barrel of the high-density polyethylene memory, and further the body of a worker is endangered, and in addition, the strength of the high-density polyethylene container barrel is poor.
In order to solve the above technical problems, referring to fig. 1 and 2, a container of a radioactive waste memory provided in an embodiment of the present invention includes a sealing layer 11, a shielding layer 12 and a protecting layer 13; the sealing layer 11, the shielding layer 12 and the protective layer 13 are of barrel-shaped structures with openings at one sides, and the sealing layer 11, the shielding layer 12 and the protective layer 13 are of integrated structures; the sealing layer 11 is used for guaranteeing the tightness of the container barrel of the radioactive waste storage; the shielding layer 12 is sleeved outside the sealing layer 11, and the shielding layer 12 is a mixed layer of high-density shielding powder and resin and is used for shielding rays; the protective layer 13 is sleeved outside the shielding layer 12 and is used for protecting the shielding layer 12 and the sealing layer 11.
