RADIOACTIVE WASTE ISSUES
A. Sources of Radioactive Waste
The radioactive waste from an accelerator facility tends
to be mostly machine components or experimental
equipment used in or near the particle beam. These
components are often of copper, iron (steel), and
aluminum. Other items or tasks contributing to
radioactive waste are:
N
Shielding blocks (iron, lead, or concrete).
N
Coolant.
N
Maintenance/modifications.
N
Cleaning materials.
1.
Shielding blocks (iron, lead, or concrete)
Shielding blocks are quite large and their highest
activity is usually below the surface. Shielding
blocks showing several rad/hr at the surface may
have no removable (wipeable) surface
contamination and can be stored without
contamination problems. Whenever possible,
shielding blocks should be stored for reuse where
dose is not a problem.
2.
If possible, cooling water should be cleaned and
recirculated/reused. The use of "pure" water
minimizes the radioactivation problems caused by
