There are five types of radioactive decay. - <font color="#f79646">Alpha Decay</font>: The unstable parent nuclide emits an alpha particle. - <font color="#f79646">Beta Decay</font>: The parent nuclide emits a beta particle. - <font color="#f79646">Gamma Decay</font>: A nucleus in an excited state emits a γ-ray photon to change to a lower energy state. - <font color="#f79646">Positron Emission</font>: A positron is emitted. - <font color="#f79646">Electron Capture</font>: An electron is captured by the nucleus. --- Return [[Home|Home]] | [[Nuclear Physics]] | [[The Nucleus]] | [[Shell Model of the Nucleus]] | [[Modes of Decay]] | [[Half-Life]] | [[Fission]] | [[Fusion]]
