Uses: Sodium iodide is commonly used as a dietary iodine supplement and included in table salt NaCl. It is used to treat and prevent iodine deficiency.
Another common application of NaI is in nuclear medicine, as radioactive sodium iodide such as NaI and NaI and its derivatives are important radiopharmaceuticals that are used for treating thyroid cancer and hyperthyroidism, and also as imaging tracers. Sodium iodide is also used as a reagent in organic synthesis to prepare various alkyl iodides. However, large doses can cause a condition called iodism, which results in headache, fever, excess salivation, bronchitis, diarrhea and vomiting.
Inhalation of the sodium iodide dust can cause irritation of throat and mucous membranes. Use fire-fighting measures that suit the surrounding fire.
