Positron Emission
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
Carbon
-11,
Nitrogen-13
,
Oxygen
-15 and
Fluorine
-18; for example:
{}^{11}\hbox{C}\;\to\;^{11}\hbox{B}\;+\;e^+\;+\;\nu_e. These isotopes are used in
positron emission tomography
.
