| When this occurs, the electron shoots out of the atom and is called a beta particle, a type of radioactivity. |
| Adding a neutron, which has one unit of mass, to 238 U gives 239 U, which decays rapidly to a new element by emitting a beta particle. |
| When a nucleus decays, through the emission of either an alpha or beta particle, the resulting new nucleus is often left in an excited state. |
| Beta emissions involve the loss of an electron from the nucleus as a beta particle during the conversion of a neutron into a proton. |
| She got hit in the hip with a beta particle dagger, but it missed most major tendons. |
| The range of the phosphorus P32 beta particle, which has a maximum energy of 1.71 MeV, is 2.8 mm of aluminium. |
