A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting gamma rays. Every chemical element has one or more radioactive isotopes.
Radioisotopes are radioactive isotopes of an element. They can also be defined as atoms that contain an unstable combination of neutrons and protons, or excess energy in their nucleus. How do radioisotopes occur? The unstable nucleus of a radioisotope can occur naturally, or as a result of artificially altering the atom.

Uranium and thorium are examples. Radioisotopes are produced as a by-product of nuclear reactors and by radioisotope generators, such as cyclotrons. Many artificial radioisotopes are used in the fields of nuclear medicine and biochemistry, in the manufacturing industry and in agriculture. Related Information. The basics of ionizing radiation
Some isotopes are unstable and emit radiation in the form of particles and energy to form more stable elements. Some forms of radiation are dangerous. These are called radioactive isotopes or radioisotopes (figure 17.1.b 17.1. b). During radioactive decay, one type of atom can change into another type of atom in this way (figure 17.1.c 17.1. c).
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess numbers of either neutrons or protons, giving it excess nuclear energy, and making it unstable.
1. What are radioisotopes? Each atomic element knows exactly how many protons and neutrons it needs at its centre (nucleus) in order to be stable (stay in its elemental form). Radioisotopes are atomic elements that do not have the correct proton to neutron ratio to remain stable.
