ABSTRACT:
The immobilization of toxic solids with a mixture of wax and a low molecular weight polyolefin is described herein. In a preferred embodiment, a mixture of between about 60-90% wax and 10-40% of either polyethylene or polypropylene is used to immobilize the low-level radioactive particulate discharged from water treatment in nuclear power plants and similar facilities. This mixture is strong, non-toxic, inexpensive, readily available, easy to handle, and resistant to breakdown, leaching, and combustion. It also mixes well with many different toxic materials. And it will hold up to about four times its weight of a toxic material having a density similar to that of the mixture and a greater weight of more dense materials.
