| 20120107173 | SYSTEM AND METHOD FOR CHEMICAL AND BIOLOGICAL AGENT DECONTAMINATION - A system and method for decontamination of chemical and biological agents over terrain in an outdoor environment is provided that utilizes ultraviolet radiation to break up hydrogen peroxide into radical species that interact with chemical and biological agents to render them harmless.
