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.

Радиоизотопный термоэлектрический генератор skr. РИТЭГ) – generator prądu elektrycznego, w którym źródłem energii jest rozpad izotopu promieniotwórczego, a wydzielone w ten sposób ciepło zamieniane jest na energię elektryczną.
A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect.
Isotopes are distinct nuclear species (or nuclides) of the same chemical element. They have the same atomic number (number of protons in their nuclei) and position in the periodic table (and hence belong to the same chemical element), but different nucleon numbers (mass numbers) due to different numbers of neutrons in their nuclei.
A radioactive isotope, also known as a radioisotope, radionuclide, or radioactive nuclide, is any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha, beta, and gamma rays. Every chemical element has one or more ...
30 lip 2020 · Radioisotopes are the unstable form of an element that emit radiation to transform into a more stable form. Radiation is easily traceable and can cause changes in the substance it falls upon. These special attributes make radioisotopes useful in medicine, industry and other areas.
Radiation, called nuclear or ionizing radiation, is always present when atomic nuclei are decaying. Some radioactive isotopes emit α (alpha) particles and others emit – β (beta) particles. Often radiation γ is also observed. A large amount of energy is released during decay.
