Iodine deficiency as a side effect of administration of iodine-containing contrast agents. In some cases, excessive iodine contributes to a risk of autoimmune thyroid diseases (Hashimoto's thyroiditis and Graves' disease). Iodine deficiency resulting in goiter occurs 187 million people globally (2.7% of the population). Certain areas of the world, due to natural deficiency and unavailability of iodine, are severely affected by iodine deficiency, which affects approximately two billion people worldwide. It is particularly common in the Western Pacific, South-East Asia and Africa. Among other nations affected by iodine deficiency, China and Kazakhstan have begun taking action, while Russia has not.

Iodine pentafluoride forming nitriles after hydrolysis with water: Iodine pentafluoride is available as a "Special Gas" for flooding into the atmosphere of the escape shuttle in the terminal sequence of 1979 film Alien. Iodine pentafluoride Iodine pentafluoride is an interhalogen compound with chemical formula IF. It is a fluoride of iodine. It is a colorless or yellow liquid with a density of 3.250 g cm. It was first synthesized by Henri Moissan in 1891 by burning solid iodine in fluorine gas. This exothermic reaction is still used to produce iodine pentafluoride, although the reaction conditions have been improved. Iodine pentafluoride is a
