Method for preparing radioactive source by microemulsion polymerization

The invention discloses a method for preparing a radioactive source by microemulsion polymerization. The method comprises the following steps: preparing a polymerizable monomer, a cosurfactant, a radioactive liquid, an initiator, an accelerator and the like into a microemulsion system, sealing the microemulsion into a mold, and carrying out polymerization reaction. The method is simple, forms the homogeneous microemulsion at normal temperature by using the polymerizable monomer and radionuclide-containing water solution, and has the advantage of uniform radionuclide distribution. The microemulsion is low in viscosity, can be conveniently filled into the corresponding mold, and is convenient to operate. The reaction system is sealed on the corresponding mold, so the polymerization reaction temperature is lower, and the reaction process can not cause pollution. The formed high-polymer polymerisate has the advantages of high strength, favorable toughness and high radioresistance.
