Isotopes of natural uranium decay by emitting mainly alpha particles. The emission of beta particles and gamma radiations are low. The table below shows the average energies per transformation emitted ...

But, in the spirit of rebranding, it is interesting to note that the main source of Earth's internal heat comes from the radioactive decay of uranium, thorium and potassium-40 that keeps the outer ...

Some elements are stable but some elements, such as uranium ... and how unstable nuclei decay release ionising radiation. He describes the nature of alpha, beta and gamma radiation, and observes ...

^{4}\textrm{He}\) and is also sometimes written as \(_{2}^{4}\alpha\). Alpha decay causes the mass number of the nucleus to decrease by four and the atomic number of the nucleus to decrease by two.
