Sentence examples for decay of radioactive elements from inspiring English sources

Both ultimately tap the heat generated by the decay of radioactive elements.

Helium is continually lost as it is produced by the decay of radioactive elements in the crust.

They are created by some of the most basic physical processes of the universe, like decay of radioactive elements and fusion reactions that power the sun.

Late in his career Dutton concluded that lava is liquefied by the heat released during decay of radioactive elements and that it is forced to the surface by the weight of overlying rocks.

Using a detector buried in a mine in Japan and cleverly screening out neutrinos emitted by nearby nuclear-power plants, the scientists were able to identify conclusively neutrinos that were emitted by the decay of radioactive elements within the Earth.

Heating of this initially cool unsorted conglomerate by the decay of radioactive elements and the conversion of kinetic and potential energy to heat resulted in the development of a liquid iron core and the gross internal zonation of Earth.

The spontaneous decay (partial disintegration) of the nuclei of radioactive elements provides decay particles and energy.

On Earth, helium is relatively rare and is created by the natural decay of some radioactive elements because the alpha particles that are emitted consist of helium nuclei.
