Iodine, in the form of iodide, is made into two radioactive isotopes that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells).odine, in the form of iodide, is made into two radioactive isotopes that are commonly used in patients with thyroid diseases: I-123 (harmless to thyroid cells) and I-131 (destroys thyroid cells).
Radioactive isotopes, also called radioisotopes, are atoms with a different number of neutrons than is usual, making them unstable.A radioisotope's nucleus decays, emitting alpha, beta and gamma rays until the isotope reaches stability.Once itâs stable, the isotope may become another element entirely, such as when uranium decays into lead.ignificance. Radioactive isotopes are useful because they produce alpha, beta and gamma rays. The radiationâs penetrating power depends on its energy, particle mass, and the objectâs density. These properties lead to many practical applications in science, medicine and industry.
