A method for preparing low level radioactive hazardous wastes (LLHZ) for disposal in a landfill. The method includes providing a softsided transportable container at a hazardous debris collection site, where the softsided container has at least three layers of materials, an outer, middle and an inner layer, where the middle layer is a water impervious material. Each layer has a closable opening located on the top of the softsided layer. Hardsided closed containers containing LLHZ located in the interior of the hard container are loaded into the interior of the softsided container. Each layer of the softsided container is then closed, and the package transported and shipped to a disposal site for burial.

1. A method for preparing low level radioactive hazardous materials (LLHZ) for disposal which comprises: providing a softsided transportable container at a hazardous debris collection site, the softsided container including a bottom, side walls and a top defining an interior space; said softsided container having at least three layers of materials, an outer, middle and an inner layer, where the middle layer is a water impervious material, each layer having a closable opening located on the top of the container; providing a hardsided closed container containing LLHZ in the interior of said container, loading said hard sided container into the interior of the softsided container, and closing each of said closable tops of said inner, middle and outer layers. 2. A method for preparing LLHZ for disposal according to claim 1, wherein the hardsided container comprises a metal or plastic container. 3. A method for preparing LLHZ for disposal according to claim 1, further comprising transporting the softsided container containing said hardsided container to a landfill site and burying the softsided container containing said hardsided container at the landfill site. 4. A method for preparing LLHZ for disposal according to claim 1, wherein each of said layers is closable with a zipper. 5. A method for preparing LLHZ for disposal according to claim 4, where said zipper on said middle layer is a water tight zipper. 6. A method for preparing LLHZ for disposal according to claim 2, wherein the inner layer has a pocket in said sidewall and a rigid material is positioned in said pocket to thereby allow said softsided container to be self-supporting. 7. A method for preparing LLHZ for disposal according to claim 1 further comprising the steps of filling the void space in said interior of said softsided enclosure with a filler after the hardsided container is positioned in said interior. 8. A method for preparing LLHZ for disposal according to claim 1 wherein the void space in said interior of said softsided enclosure is not filled with a filler. 9. A method for preparing LLHZ for disposal according to claim 1 wherein said LLHZ contains objects with sharp edges. 10. A method for preparing LLHZ for disposal according to claim 1 wherein said hardsided container is a 55 gallon drum. 11. The method for preparing LLHZ for disposal according to claim 6 wherein said rigid material comprises cardboard material. 12. The method for preparing LLHZ for disposal according to claim 6 wherein each of said layers is closable with a zipper. 13. The method for preparing LLHZ for disposal according to claim 3 wherein said inner layer is constructed of non-woven polypropylene. 14. The method for preparing LLHZ for disposal according to claim 13 wherein said outer layer is constructed from woven or non-woven polypropylene. 15. The method for preparing LLHZ for disposal according to claim 2 wherein said middle layer is closable with a toothless zipper. 16. The method for preparing LLHZ for disposal according to claim 15 wherein said inner layer is closeable with a zipper. 17. A method for preparing LLHZ for disposal according to claim 2, wherein the softsided transportable container further comprises a rigid material positioned adjacent the inner layer. 18. The method of claim 1 wherein said hardsided closed container is sealed closed. 19. A method for preparing low level radioactive hazardous materials (LLHZ) for disposal which comprises: providing a softsided transportable container at a hazardous debris collection site, the softsided container including a bottom, side walls and a top defining an interior space; said softsided container having at least three layers of materials, an outer, middle and an inner layer, where the middle layer is a water impervious material, each layer having a closable opening located on the top of the container; providing a hardsided closable container, positioning LLHZ in the interior of said container, closing said hard sided container, loading said hard sided container into the interior of the softsided container, and closing each of said closable tops of said inner, middle and outer layers. 20. The method of claim 19 wherein said step of loading said hard sided container into the interior of the softsided container occurs before said step of positioning LLHZ in the interior of said hardsided container.
