A cyclotron shielding device with a layered structure comprises a magnetic component for generating a magnetic field and a particle acceleration component for accelerating protons. The particle acceleration component is provided with a beam extraction tube, and the beam extraction tube is used for extracting beams in the particle acceleration component. In order to effectively shield the radiation source, the target part extends into a local shielding assembly for moderating the particles. The local shielding assembly is attached to the layered shielding device, the layered shielding device comprises N liquid layers and N + 1 solid layers, and the solid layers and the liquid layers are arranged in a staggered mode. The structure of the layered shielding device 15 is preferably a molten iron mixed type layered shielding structure. The cyclotron shielding device with the layered structure has the advantages that a radiation source is effectively shielded, the occupied area is reduced through the structure, the
