Iodine (radioactive)

Radioactive iodine is a form of the element iodine that emits radiation as it decays. It is naturally produced in small amounts by the earth and can also be created artificially for medical purposes. When used in medicine, it helps diagnose and treat thyroid conditions because the thyroid gland readily absorbs iodine. Radioactive iodine’s decay releases energy that can damage or destroy overactive or diseased thyroid tissue, offering targeted therapy. While useful in medical treatments, its radiation can pose health risks if not handled properly, and exposure needs careful management to protect surrounding tissues and overall health.
