Radioactive Isotopes and X-rays ... Radioactive isotopes have unstable nuclei that spontaneously change to form more stable nuclei. As a result, either new isotopes or new elements are produced. In this process of nuclear change, three kinds of rays, called alpha, beta, and gamma rays, are emitted from the nuclei...

For each element there are different isotopes, atoms with the same number of protons but different numbers of neutrons. For example, carbon atoms always have six protons, but may have six, seven, or eight neutrons. ... Some isotopes are stable, but others are radioactive.
