Removing radioactive contaminants from liquid hazardous material such as oil, includes recirculating the material between a processing tank and a filter medium. The material is heated to increase viscosity during the circulation through the tank and filters. Chemicals including chelating agents are added to enhance the removal of the radioactive elements. Water is added to the processing tank or upstream, in a settling tank, to effect a water wash of the liquid hazardous material. A pre-filter stage upstream of the settling tank is followed by a mid-range filter stage in the recirculation loop with the main processing tank. A finishing filter stage is in the outlet from the main processing tank.
