Potassium iodide

• Radiation Protection: Potassium iodide is known for its ability to protect the thyroid gland from radioactive iodine, particularly in the event of a nuclear accident or emergency. It saturates the thyroid with non-radioactive iodine, preventing uptake of radioactive iodine-131.
• Nutritional Supplement: Iodine is essential for thyroid function and overall health. Potassium iodide supplements can be used to prevent iodine deficiency, which can lead to thyroid disorders like goiter and hypothyroidism.
• Chemical Reagent: Potassium iodide is also used in various chemical reactions and laboratory procedures, including as a source of iodide ions in solutions.
• Photography: It has historical use in photography, particularly in the production of daguerreotypes.
• Medical Applications: In medicine, it can be used in certain treatments, such as in the management of some types of hyperthyroidism.
