I-131 (Iodine-131)

Iodine-131 (I-131) is a radioactive isotope of iodine used primarily in medical treatments for thyroid conditions, such as thyroid cancer and hyperthyroidism. The thyroid gland, located in the neck, naturally absorbs iodine from the bloodstream to produce hormones. When I-131 is administered, it is selectively taken up by the thyroid tissue. Its radioactive properties allow it to destroy overactive or cancerous cells through targeted radiation, providing effective treatment with minimal impact on other body parts. I-131 treatment is well-established and monitored carefully to ensure safety and therapeutic effectiveness.
