Claim 3:
4. The system of claim 1, wherein the third preprocessing member comprises a high-voltage discharge member, a hydrogen gas generator, and an electric adsorption portion and is so configured that the polluted air containing radioactive materials is ionized by dissociating a covalent bond of a harmful material molecule in a process of high-voltage discharge, a hydrogen gas generated from a hydrogen generator is injected into a resulting ionized air and mixed together, and an air containing radioactive materials mixed with hydrogen has the radioactive materials adsorbed onto an ion exchange resin layer coated onto an outer surface of a discharge electrode and a ground electrode of the electric adsorption portion, while high voltage is applied to the discharge electrode and the ground electrode at the same time, so that the radioactive materials on the ion exchange resin layer are activated and adsorbed onto the resin layer with a hydrogen molecule dissociated into a hydrogen cation, thereby removing the radioactive materials through a reduction reaction of the radioactive materials in association with the hydrogen cation and an activated metal ion of the ion exchange resin layer.
