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. According to the present invention, since heavy lead which is harmful to the human body and the environment is not used, side effects such as disease or environmental pollution caused by lead do not occur, the light weight of the radiation shielding sheet is enabled, and protective clothing with excellent wearing sensation can be manufactured, and since flexibility can be improved compared to lead rubber sheets, handling and storage are convenient. In addition, the lead-free radiation shielding sheet manufactured by the present invention can be applied as clothes of various designs and radiation protection means for various uses due to flexibility and ease of operation.
