Fermion

So is nuclear radiation. Does it mean:
| the electric or magnetic force that acts between oppositely charged bodies, tending to draw them together |
| radiation in the form of elementary particles emitted by an atomic nucleus produced by decay of radioactive substances or by nuclear fission |

fermion  (fûr'mē-ŏn', fěr'-) Pronunciation Key
An elementary or composite particle, such as an electron, quark, or proton, whose spin is an integer multiple of 1/2 . Fermions act on each other by exchanging bosons and are subject to the Pauli exclusion principle, which requires that no two fermions be in the same quantum state. Fermions are named after the physicist Enrico Fermi, who along with Paul Dirac developed quantum statistical models of their behavior. Compare boson. |
