Student's Guide
Lesson Plan
Notes
4.
Soils
Soils surrounding buried beam dumps may become activated.
These can become classified as radioactive waste when
facilities are modified or decommissioned.
B.
Minimizing Radioactive Waste
Because of the difficulty and cost in disposing of radioactive waste,
special care should be taken to minimize waste generated.
Avoid bringing unnecessary material into accelerator
N
enclosures.
Designate an area to store contaminated tools for
N
reuse.
Plan your work so that, whenever possible,
N
construction and clean maintenance can be done in a
clean area.
Do not leave unnecessary tools and equipment in
N
accelerator enclosures.
Reuse items

C.
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.
1.
Sources of mixed waste.
Common examples of waste materials at accelerators are:
Lead (shielding, batteries, etc.).
N
PCBs
N
Cadmium.
N
Acids.
N
Bases.
N
