1. A method for collecting and removing radon and radon daughters from a confined area, the method comprising:incorporating a plurality of radon adsorbers within a structure of the confined area;negatively biasing the plurality of radon adsorbers within the structure by a metal fiber coating applied thereon; andattracting the radon daughters on surfaces of the plurality of radon adsorbers. 2. The method of claim 1, wherein the structure is a building. 3. The method of claim 1, wherein the negative bias is maintained for a predetermined period of time. 4. The method of claim 1, wherein the negative bias is maintained for months or years. 5. The method of claim 1, wherein the metal fiber coating includes a steel core or other suitable mesh surrounded by a material such as nickel-iron (NiFe) alloy or any other suitable materials such that a fermi level of the materials are lower than that of a core material so that a surface of the coating has a negative charge. 6. The method of claim 5, wherein the material(s) has a thickness between about 5 nm and about 100 nm.
