Wherein the radioactive material is 32 P and/or 90 Y, the nuclide labeled compound is not readily soluble in water. The sealing layer 1 is arranged above the polymer film layer 2 and used for protecting the polymer film layer 2, and consists ofThe medical patch has certain toughness and can realize structural support on the radioactive patch. When the radioactive patch is used, one side of the thermoplastic film layer 3 of the radioactive patch is stuck to the skin at a focus, and the thermoplastic film layer 3 has certain viscosity, so that the radioactive patch can be tightly stuck to the skin, and can prevent the skin from being directly contacted with the polymer film layer 2, thereby playing a role of isolating radioactive substances, and the thermoplastic film layer 3 has a soft structure and better comfort of sticking to the skin. In addition, the thermoplastic film layer 3 and the polymer film layer 2 are tightly combined together through lamination, so that the release of radioactive substances can be reduced.
