	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.

		Radioactive waste is managed at Mayak in various ways, using reservoirs, storage tanks, waste burial sites, and a vitrification plant.
		This reaction was the cause of the 29 September 1957 explosion of a waste storage tank, known as the "Kyshtym Disaster," which spread 70-80MT of waste over a region between 15,000 and 23,000 square kilometers in area.
		After the accident, this practice of merely returning the waste to the storage tanks was discontinued and replaced with a process of evaporation and fixation in compounds such as hydroxides and ferrocyanides.
