Radioactive decay (also known as nuclear decay, radioactivity, radioactive disintegration or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation. A ...

This event was the first time that water had been used to detect a particle known as an antineutrino, which had been fired ...

Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma ...
