potassium iodide for radiation exposure

People are asking about potassium iodide for radiation exposure from nuclear reactor problems or other causes.

Potassium iodide (KI) blocks accumulation of radioactive iodine in the thyroid. This helps prevent thyroid cancer...but it doesn't protect other organs or protect against other forms of radiation.

In an emergency, public health agencies will mobilize distribution of KI from stockpiles...first to children for their fast-growing thyroids.
