Abstract: The present invention discloses a method for manufacturing a lead-free radiation shielding sheet. The method for manufacturing a lead-free radiation shielding sheet according to the present invention comprises a film laminating step of forming a multi-layered radiation shielding film on one side of a base material by repeating a process of applying to laminate, drying, and integrating a radiation shielding material containing a radiation shielding powder and a binder for forming a film to be mixed with each other on one side of the base material for forming a radiation shielding sheet.
