Public Participation Guide: Introduction to Public Participation

Public participation can be any process that directly engages the public in decision-making and gives full consideration to public input in making that decision.

Radionuclide Basics: Plutonium

Plutonium (chemical symbol Pu) is a radioactive metal. Plutonium is considered a man-made element. Plutonium-239 is used to make nuclear weapons. Pu-239 and Pu-240 are byproducts of nuclear reactor operations and nuclear bomb explosions.

Radionuclide Basics: Iodine

Iodine (chemical symbol I) is produced commercially for medical and industrial uses through nuclear fission. Iodine-129 and I-131 are the radioisotopes that are commonly used and will have the greatest impact on the environment if released.

Radionuclide Basics: Cobalt-60

Cobalt (chemical symbol Co) is a hard, gray-blue metal that is solid under normal conditions. The most common radioactive isotope of cobalt is cobalt-60 (Co-60).
