Radioactive isotope: Radioactive isotope, any of the species of the same chemical element that have different masses and unstable nuclei that emit radiation. Uses of Radioactive Elements - Free download as (.rtf), PDF File (.pdf), Text File (.txt) or read online for free. For iodine 131, the half life is short, only about eight days. Radioactive elements are exothermic in their reactions. The application of x-rays and radioactive materials is far reaching in medicine and industry. Radioactive isotopes are effective tracers because their radioactivity is easy to detect. Uses Polonium releases a great deal of energy during its radioactive breakdown.  Only hydrogen-3 , however, is a radioactive isotope, the other two being stable. Radioactive elements are emitting energy all the time, and their existence is measured by half-life  how long it takes for half of a given amount to give off its radiation and decay into a different material. Radioactive elements are used all the time. Isotopes are alternative versions of elements that have a different atomic mass but the same atomic number. But for cesium 137, it is about 30 years.
