The major uses of Potassium Iodide include
nutritional supplement in animal feeds, a precursor to Silver Iodide, and as a component in disinfectants. Potassium iodide is also added to hair chemicals, and sometimes table salt in small quantities to make it "iodized." Potassium iodide was approved by the US FDA to protect the thyroid glands from radioactive iodine produced by an accident or attack at a nuclear power plant, or fallout from a nuclear bomb. Potassium iodide cannot protect against any other causes of radiation poisoning, nor can it provide any degree of protection against dirty bombs that produce radionuclides other than
isotopes of iodine.
