  • Patent number: 4865061
    Abstract: Disclosed is a self-contained, portable apparatus for cleaning chemical and/or radioactively contaminated articles. A cleaning chamber is provided where contaminated articles are placed. Solvent from a solvent reservoir is sprayed onto the contaminated articles to dissolve the chemical contaminants and to dislodge the radioactive particulates. The solvent and contaminants drain through a short vertical duct connecting the cleaning chamber to the solvent reservoir. There is a cooling means present in the short vertical duct which serves to condense the solvent vaporized during the cleaning operation. A filter means is provided to filter particulate contaminants from the solvent before the solvent is delivered from the solvent reservoir to the cleaning chamber.
