This paper describes the development of an in situ decontamination procedure by applying onto the contaminated surface (in a one-step or multi-step process), a paste containing chemically aggressive agents, causing dilution and adsorption of the contaminant which then hardens to form a strippable foil. The use of such a foil results in the following advantages with respect to usual techniques: - sensibly shorter operation duration resulting in lower personnel doses; - reduction of the volume of secondary waste, the volume of the spent strippable foil being much smaller than the volume of water currently used for washing; - optimal conditioning of the radioactive waste due to its fixation in the solid foil, and - ease of containment of any accidental contamination in a controlled area.
