title="Gallium">gallium</a> (<sub>31</sub>Ga) consists of a mixture of two stable <a href="/wiki/Isotope" title="Isotope">isotopes</a>: gallium-69 and gallium-71. Twenty-nine <a href="/wiki/Radioisotope" class="mw-redirect" title="Radioisotope">radioisotopes</a> are known, all synthetic, with <a href="/wiki/Atomic_mass" title="Atomic mass">atomic masses</a> ranging from 60 to 89; along with three <a href="/wiki/Nuclear_isomer" title="Nuclear isomer">nuclear isomers</a>, <sup>64m</sup>Ga, <sup>72m</sup>Ga and <sup>74m</sup>Ga. Most of the isotopes with <a href="/wiki/Atomic_mass_number" class="mw-redirect" title="Atomic mass number">atomic mass numbers</a> below 69 decay to isotopes of <a href="/wiki/Zinc" title="Zinc">zinc</a>, while most of the isotopes with masses above 71 decay to isotopes of <a href="/wiki/Germanium" title="Germanium">germanium</a>. Among them, the most commercially important radioisotopes are gallium-67 and gallium-68. </p><p>Gallium-67 (half-life 3.3 days) is a gamma-emitting isotope (the gamma ray emitted immediately after electron capture) used in standard nuclear medical imaging, in procedures usually referred to as <a href="/wiki/Gallium_scan" title="Gallium scan">gallium scans</a>. It is usually used as the free ion, Ga<sup>3+</sup>. It is the longest-lived radioisotope of gallium. </p><p>The shorter-lived gallium-68 (half-life 68 minutes) is a <a href="/wiki/Positron" title="Positron">positron</a>-emitting isotope generated in very small quantities from germanium-68 in <a href="/wiki/Gallium-68_generator" title="Gallium-68 generator">gallium-68 generators</a> or in much greater quantities by proton bombardment of <sup>68</sup>Zn in low-energy medical <a href="/wiki/Cyclotron" title="Cyclotron">cyclotrons</a>,<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> for use in a small minority of diagnostic <a href="/wiki/PET_scan" class="mw-redirect" title="PET scan">PET scans</a>.
