Potassium iodide is a salt that is routinely added to table salt to make it “iodized.” Its chemical symbol is KI. If taken in time and at the appropriate dosage, it can block the uptake of radioactive iodine by the thyroid gland and thus reduce the risk of thyroid cancers and other diseases that might otherwise be caused by exposure to any radioactive iodine dispersed in a severe nuclear accident.*

Radiological Emergency Preparedness

A radiological emergency occurs when there is a nuclear accident, such as at a nuclear power plant.

Radiological emergency preparedness is for protecting people from the effects of radiation exposure after a nuclear accident. Evacuation is the most effective protective measure in the event of a radiological emergency, because it protects the whole body (including the thyroid gland and other organs) from all radionuclides and along all pathways of exposure. Administering KI can be a reasonable, prudent, and inexpensive measure, whether sheltering in-place or evacuating.*

Potassium iodide provides a specialized kind of protection. It protects the thyroid gland against the internal uptake of radioiodines that may be released during a radiological emergency.*

Effects of Radiation on the Thyroid Gland

Given radiation exposure (through inhalation, ingestion, or both), and if that radiation contains radioiodines, and, further, if the thyroid gland is not already saturated with another form of iodine, the thyroid may take up radioiodines. Acute, chronic, and/or delayed effects from high doses include:*

  • Thyroiditis (inflammation of the thyroid gland)
  • Hypothyroidism
  • Thyroid nodules
  • Thyroid cancer


Product Benefits

When potassium iodide is ingested, it is absorbed by the thyroid gland. In the proper dosage, and taken at the appropriate time, it will saturate the thyroid gland so that inhaled or ingested radioactive iodine can not be accumulated in the saturated gland. The risk of thyroid effects from radiation exposure is reduced.*
