Soils
Soils surrounding buried beam dumps may become activated.
These can become classified as radioactive waste when
facilities are modified or decommissioned.

Mixed Waste
Mixed waste is waste that is classified as hazardous in accordance to
the Environmental Protection Agency (EPA) AND is also radioactive.
There is presently no approved method to dispose of mixed waste, and
long-term storage is required.
