==Key Stage 5==
===Meaning===
[[Beta Decay|Beta decay]] is a type of [[Radioactive Decay|radioactive decay]] involving the transformation of a [[neutron]] into a [[proton]] or vice versa, accompanied by the [[Emit|emission]] of a [[Beta Particle|beta particle]] and a [[neutrino]] or [[antineutrino]].
===About Beta Decay===
*In [[Beta-Minus Decay|beta-minus (β⁻) decay]], a [[neutron]] turns into a [[proton]], an [[electron]], and an [[antineutrino]].
*In [[Beta-Plus Decay|beta-plus (β⁺) decay]], a [[proton]] turns into a [[neutron]], a [[positron]], and a [[neutrino]].
*Occurs in [[Neutron-rich Nucleus|neutron-rich]] or [[Proton-rich Nucleus|proton-rich]] [[Atomic Nucleus|nuclei]].
*The [[emit]]ted [[Beta Particle|beta particles]] are [[electron]]s or [[positron]]s.
*[[Beta Radiation|Beta radiation]] is less ionizing than [[Alpha Radiation|alpha radiation]] but more than [[Gamma Radiation|gamma radiation]].
===Examples===
*[[Carbon-14]] undergoes [[Beta-Minus Decay|β⁻ decay]] to become [[nitrogen]]-14.
*[[Fluorine-18]] undergoes [[Beta-Plus Decay|β⁺ decay]] in [[PET Scan|PET scan]]s.
