(ß
-) An electron emitted by an unstable nucleus, when a neutron decays into a proton and an electron. In some cases, beta radiation consists of positrons ('antielectrons' which are identical to electrons but carry a +1 charge.') Note that beta particles are created in nuclear decay; they do not exist as independent particles within th...

A fast-moving electron or positron (anti-electron) that is emitted from a nucleus during the radioactive process known as beta decay. Large amounts of beta radiation may cause skin burns, and beta emitters are harmful if they enter the body. Beta particles may be stopped by thin sheets of metal or p...

The beta particle has the form of a high speed negatively charged electron (or a positively charged electron in the case of the positron). In beta decay (electron emission) a neutron in the nucleus is converted to a proton with the release of a high speed electron and an antineutrino. In the example C-14 decays to N-14. Note the atomic number has ....

Beta particle: An electron ejected from the nucleus of a decaying atom. Although beta particles can be stopped by a thin sheet of aluminum, they can penetrate the dead skin layer, potentially causing burns. They can pose a serious direct or external radiation threat and can be lethal depending on the amount received. They also pose a serious intern...

Electron ejected with great velocity from a radioactive atom that is undergoing spontaneous disintegration. Beta particles are created in the nucleus on disintegration, beta decay, when a neutron converts to a proton (the atomic number increases by one while the atomic mass stays the same) by emitting an electron.
