Waste streams vary considerably in their level of radiation contamination; accordingly, wastes from various decontamination activities must be characterized as to whether they can be released or whether they require further concentration to reduce their volume for economical disposal. Following measurement, the appropriate separation method can be selected.

The removed solids, or filter cake could be sent to a landfill or low-level radioactive waste disposal, and the water recycled through the process,~or released if clean enough to meet release criteria. Chemical precipitation, in which reagents are added to an aqueous waste to precipitate as solids the materials to be separated (e.g., uranium compounds)

Grouting can be used for the treatment of solid wastes- from scabbling of concrete surfaces, other solids from mechanical decontamination, dusts trapped by filters, solids filtered from aqueous streams, some slurries and sludges, and similar waste materials. The grout can be poured into burial vaults or containers where it sets or hardens for disposal.

are given below (Cohen and Associates, 19941. Advantages of recycling RSM are as follows: avoidance of disposal costs; resource savings from use of recycled RSM in place of virgin metals; an immediate solution for the disposition of RSM and avoidance of surveillance and maintenance costs; and may be politically preferable to land disposal if the health hazards are low.

Stainless steel could be smelted and cast into slabs that could then be rolled and fabricated in a dedicated facility, such as the one at Oak Ridge, to form waste disposal canisters or casks.
