Definitions for "Potassium Iodide"
One of several ingredients that can be added to table salt to iodize it. KI prevents only the thyroid gland from absorbing one kind of radiation - radioactive iodine. Iodized salt will not provide enough iodine to protect the thyroid and should not be used as a substitute. In the event of a nuclear emergency you may be given KI and instructed to take it. It should only be taken when directed by public officials.
Potassium Iodide has been approved by the FDA as a nonprescription drug for use as a "blocking agent" to prevent the human thyroid gland from absorbing radioactive iodine.
A drug used to treat certain thyroid disorders. It can also be used to block the uptake by the thyroid of radioactive-iodine isotopes that are released in a nuclear-reactor accident.
