Abstract

See full text

A process for treating radioactive contaminated soils to remove radioactive metal oxide contaminants therefrom comprises creating a suspension of particles of the soil in a column of water, alternately forcing fresh water in the column upwardly to force ligher soil particles upwardly in the column and allowing heavier particles to gravitationally settle in the bottom of the water column. The heavy particles comprising radioactive metal oxides are collected and handled for radioactive waste material storage. The aqueous slurry of lighter soil particles is directed to a separator for removing substantial amounts of water after which the particles are directed to a conveyor and spread out to a substantially uniform thickness and detected for any radioactivity. Portions of material in which radioactive particles are detected ar diverted and the uncontaminated soil material is recovered.
