Title:
RADIOACTIVE DECONTAMINATION AND TRANSLOCATION METHOD
Document Type and Number:
WIPO Patent Application WO2004038731
Kind Code:
A3
Abstract:
A method for removing a wide variety of radioactive contaminants from a contamined surface sufficient for the surface to be classified as a low-level waste or as free release. Contaminated surface may be classified as Class C, Class B, Class A, or high-level radioactive wastes prior to treatment. An aqueous solution having a wetting agent and a complex substituted keto-amine is provided. The aqueous solution is left on the surface for a time sufficient to remove the radioactive contaminants into the aqueous solution which is then removed. Depending on the type and condition of the surface, an acid may be added to the aqueous solution to aid in the contaminant removal process. However, typical metals surfaces may often be treated effectively without the use of concentrated acids or with dilute concentrations of such acids. The method of the present invention has the effect of removing substantially all of the radioactive contaminants from a variety of previously contaminated surfaces.
