Low-level radioactive waste, such as contaminated gloves, can be disposed of in landfill sites. Higher level waste, which may be dangerously radioactive, is more difficult to dispose of. It can be reprocessed to extract nuclear fuel or encased in glass and left deep underground.High-level
radioactive or nuclear waste is “spent” uranium fuel used in nuclear reactors.
This spent fuel is thermally hot and highly radioactive, usually in the form of
uranium 235 contained in ceramic pellets inside metal rods. Disposing of highly dangerous substances such as nuclear waste can be very dangerous and harmful, therefore people who are specilised in dealing with stuff like this always have to wear safe equipment.
