radioactive heating

(a source of heat of some planets and moons)

Radioactive heating is heating due to radioactive decay, i.e., emission of alpha rays, beta rays (beta decay), or gamma rays, from unstable isotopes. It can be a significant source of heat within planets and moons, including Earth and the Moon. It has also been used as a spacecraft energy source.
