Positron emission is a type of beta decay, referred to as "beta plus" (β+). In beta plus
decay, a proton is converted to a neutron
via the weak nuclear force and a beta plus particle (a positron) and a neutrino are emitted. Isotopes which emit positrons
include C-11, N-13, O-15 and F-18; for example:
-
These isotopes are used in positron emission
tomography.
