삼요오드화물, or iodine-131, is a radioactive isotope of iodine commonly used in medical applications, particularly in the treatment of thyroid conditions. It emits beta and gamma radiation, which helps to destroy overactive thyroid cells, making it effective for conditions like hyperthyroidism and certain types of thyroid cancer. In addition to its medical uses, 삼요오드화물 is also utilized in nuclear medicine for diagnostic imaging. Patients ingest or receive it through injection, allowing doctors to monitor thyroid function and detect abnormalities. Its short half-life means it decays quickly, minimizing radiation exposure to the patient.
