    摘要: As a method of decontaminating a surface covered with a chemical contaminant, a light-absorption agent providing a relatively high neutral density is applied to the surface in intimate contact with the contaminant. Then one or more flashes of high intensity, broad-band frequency, incoherent light is applied to the surface, whereupon, the light-absorption agent converts the absorbed light energy to heat, resulting in vaporization and/or decomposition of the contaminant. The heat generated by the short duration flash is localized at the material on the surface and at a very thin surface layer, and vaporization of the surface material dissipates the heat that is generated, whereby, the surface is substantially unaffected by the process.
