*[[Beta-Minus Radiation|Beta-minus]] [[particle]]s are high-energy, high-speed [[electron]]s.
*Stopped by about 5 mm of [[aluminium]].
*Has a range in air of up to a [[metre]].
*Less ionizing than [[Alpha Radiation|alpha radiation]] but more ionizing than [[Gamma Radiation|gamma radiation]].
*[[Beta-Minus Radiation|Beta-Minus radiation]] is [[emit]]ted during beta-minus decay when a [[neutron]] [[Transmutation|transmutes]] into a [[proton]], [[electron]], and [[antineutrino]].
*[[Beta-Minus Radiation|Beta-minus radiation]] is used in medical applications and radiometric dating.
