<p><b>New page</b></p><div>Several dozen [[radioisotope]]s have been characterized. {{chem|65|Zn}}, which has a half-life of 243.66&nbsp;days, is the least active radioisotope, followed by {{chem|72|Zn}} with a half-life of 46.5&nbsp;hours. Zinc has 10 [[nuclear isomer]]s, of which <sup>69m</sup>Zn has the longest half-life, 13.76 h. The superscript ''m'' indicates a [[metastable]] isotope. The nucleus of a metastable isotope is in an [[excited state]] and will return to the [[ground state]] by emitting a [[photon]] in the form of a [[gamma ray]]. {{chem|61|Zn}} has three excited metastable states and {{chem|73|Zn}} has two. The isotopes {{chem|65|Zn}}, {{chem|71|Zn}}, {{chem|77|Zn}} and {{chem|78|Zn}} each have only one excited metastable state.</div>FuzzyBot
