Understanding the Uses and Effects of Radioactive Iodine (RAI)

Overview of Radioactive Iodine (RAI)

Radioactive Iodine, also known as Iodine-131, is a radioactive isotope of the element iodine. It is commonly used in the treatment of thyroid disorders, including hyperthyroidism and certain types of thyroid cancer.

When administered in a controlled medical setting, Radioactive Iodine can be an effective treatment option for thyroid conditions. It works by selectively targeting and destroying thyroid tissue, including cancerous cells, while minimizing damage to surrounding healthy tissues.

Radioactive Iodine therapy is typically given in the form of a capsule or liquid that is swallowed by the patient. Once ingested, the Radioactive Iodine is absorbed by the thyroid gland and begins to emit radiation, targeting abnormal thyroid cells.

Patients undergoing Radioactive Iodine treatment may need to follow specific precautions to minimize radiation exposure to others. This may include isolation from family members and avoiding close contact with others for a period of time after treatment.

It is important for patients to follow their healthcare provider’s instructions closely during and after Radioactive Iodine therapy to ensure the best possible outcomes and minimize potential side effects.

For more information on Radioactive Iodine therapy, you can refer to reputable sources such as the National Cancer Institute and the American Thyroid Association.
