An alpha particle is also a Helium-4 nucleus. It is written as \(_{2}^{4}\textrm{He}\) and is also sometimes written as \(_{2}^{4}\alpha\). Alpha decay causes the mass number of the nucleus to ...

Instead, they rely on the radioactive decay of elements to produce heat and eventually electricity. While this concept sounds ...

Physicists develop innovative technique using carbon-dioxide lasers to detect radioactive materials from safe distances for ...

Researchers at CERN have observed an exceptionally rare particle decay event, potentially paving the way to uncover new ...

In beta decay, a proton or neutron in a nucleus ... the researchers determined the energies and directions of the emitted beta particle and two alpha particles with high precision.

Radioactive decay, or nuclear decay ... When the plutonium-238, which starts with 94 protons, releases an alpha particle, it loses two protons and turns into uranium-234, which has 92 protons.
