Radioactive iodines are produced during the operation of nuclear power plants and
during the detonation of nuclear weapons. In the event of a radiation incident,
radioiodine is one of the contaminants that could be released into the environment.
Exposure to radioiodine can lead to radiation injury to the thyroid, including thyroid
cancer. Radiation to the thyroid from radioiodine can be limited by taking a nonradioactive
iodine (stable iodine) such as potassium iodide. This book assesses strategies
for the distribution and administration of potassium iodide (KI) in the event of a
nuclear incident. The report says that potassium iodide pills should be available to
everyone age 40 or younger—especially children and pregnant and lactating
women—living near a nuclear power plant. States and municipalities should decide
how to stockpile, distribute, and administer potassium iodide tablets, and federal
agencies should keep a backup supply of tablets and be prepared to distribute them
to affected areas.
