Low-Level Radioactive Waste (LLRW) includes radioisotope waste generated in industry, hospitals, research, and the objects associated with the nuclear fuel cycle. LLRW rarely needs shielding and consists mainly of items with short-lived radioactivity. Usually, they are compacted and shallowly buried. Materials include paper, clothing, and other materials that may have been exposed to radioactivity. Intermediate Level Radioactive Waste (ILRW)has greater levels and periods of radioactivity. These materials may require a geologic burial. These materials include resins, reactor fuel rod cladding, and strongly contaminated materials. High-level radioactive waste is generated as byproducts of the Nuclear fuel cycle.
