Radioactive waste that is not high-level waste, transuranic waste, spent nuclear fuel, or by-product tailings from processing of uranium or thorium ore. See: Radioactive Waste. Optional addition: Low-level radioactive waste is generated in many physical and chemical forms and levels of contamination. Note: If the document uses this term to mean only low-level waste that is subject to the AEA, it may be appropriate to add "accelerator-produced waste" and "naturally occurring radioactive material" to the list of exclusions
