  IEER On-Line Classroom: Classifications of Nuclear Waste
Radioactive Waste: In general, radioactive waste classes are based on the waste's origin, not on the physical and chemical properties of the waste that could determine its safe management.
Radioactive waste is produced by a number of sources, but by far the largest quantities -- in terms of both radioactivity and volume -- are generated by the commercial nuclear power and military nuclear weapons production industries, and by nuclear fuel cycle activities to support these industries such as uranium mining and processing.
Since "low-level" radioactive waste is defined by what it is not, it thus includes everything from slightly radioactive trash (such as mops, gloves, and booties) to highly radioactive activated metals from inside nuclear reactors.
