How do radioactive elements decay? Elements that emit ionizing radiation are called radionuclides. When it decays, a radionuclide transforms into a different atom – a decay product. The atoms keep transforming to new decay products until they reach a stable state and are no longer radioactive.
What causes an atom to decay? Atoms radioactively decay when a lower-energy nuclear configuration exists to which they can transition. The actual decay event of an individual atom happens randomly and is not the result of the atom getting old or changing through time.
Do all radioactive elements decay? Radioactive decay is seen in all isotopes of all elements of atomic number 83 (bismuth) or greater. Bismuth-209, however, is only very slightly radioactive, with a half-life greater than the age of the universe; radioisotopes with extremely long half-lives are considered effectively stable for practical purposes.
What is radioactive decay used for? Scientists and engineers use radioactivity as a source of heat for satellites, for medical imaging, for targeted cancer treatments, for radiometric dating, and for research into the laws of nature and the origin of matter.
