WebIodine-131 (also known as I-131) is a radioisotope of iodine. Radioisotopes release radiation. Iodine-131 concentrates in the thyroid, and is used in medical diagnostic procedures, to treat thyroid cancer, and to remove the thyroid in people with hyperthyroidism (a condition in which the body makes too much thyroid hormone). Web2. There are actually quite a few more decay paths for 131 I. In a practical situation, however, you don't select a particular decay to detect because your detector (unless you are using a single channel analyzer) will detect all of the radiation within it's range. In practice, you collect a gamma spectrum * from your sample and then analyze ...
