| Positively charged beta particles, the antiparticle of electrons, are called positrons. |
| Unstable atoms that lie below the band of stability, and therefore have excess neutrons, are likely to decay by emission of beta particles. |
| In 1899 he identified two forms of radioactivity, which he called alpha and beta particles. |
| A radioactive atom used in nuclear medicine that shows radioactive disintegration and emits alpha and beta particles or gamma rays. |
| A common emitter of negative beta particles is carbon-14, the radioactive isotope of carbon that is found in all living plants and animals. |
| When taken up by obstacles, beta particles produce a more penetrative secondary radiation known as bremsstrahlung. |
