Radiation shielding material

A radiation shielding material for shielding radiation and radioactivity generated from a radiation waste of a medical institution or a radioactive waste of a nuclear facility, the radiation shielding material comprising:

• a carbon fiber layer (101);
• a first shielding layer (102) formed by mixing red clay and barley stone powder with water while stirring the same so as to be soaked into the carbon fibers and formed to have a predetermined thickness on each of both surfaces thereof;
• and a lacquer film layer (103) formed in such a manner that a plurality of carbon fiber layers 101 are sequentially laminated to form a multi-layer, the carbon fiber layer 101 is formed on an outermost surface skin layer, and the lacquer film layer (103) is formed by applying lacquer on a surface of the carbon fiber layer (101) of the surface skin layer in a manner of repainting.

A radiation shielding material that is cured as a single body concrete layer by inserting a plurality of lacquered carbon fibers spaced apart from each other between concretes in which a radiation shielding metal oxide is mixed.

A radiation shielding material comprising:

• a base layer (10) formed of a concrete layer in which a radiation shielding metal oxide is mixed;
• and
• a second shielding layer (30) formed by multi-laminating lacquered carbon fibers on both or one of outer surfaces of the base layer (10)
