| h English (en) | Several dozen [[radioisotope]]s have been characterized. {{chem|65|Zn}}, which has a half-life of 243.66 days, is the least active radioisotope, followed by {{chem|72|Zn}} with a half-life of 46.5 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. |
| h Japanese (ja) | 数十種類の[[radioisotope/ja|放射性同位体]]が特徴づけられている。半減期が243.66 日の{{chem|65|Zn}}は最も活性の低い放射性同位体であり、半減期が46.5 時間の{{chem|72|Zn}}がそれに続く。亜鉛には10個の[[nuclear isomer/ja|核異性体]]があり、そのうち<sup>69m</sup>Znの半減期は13.76時間と最も長い。上付き文字''m''は[[metastable/ja|準安定]]同位体を示す。準安定同位体の原子核は[[excited state/ja|励起状態]]にあり、[[gamma ray/ja|ガンマ線]]の形で[[photon/ja|光子]]を放出することで[[excited state/ja|基底状態]]に戻る。{{chem|61|Zn}}には3つの励起準安定状態があり、{{chem|73|Zn}}には2つの励起準安定状態がある。同位体{{chem|65|Zn}}、{{chem|71|Zn}}、{{chem|77|Zn}}、{{chem|78|Zn}}はそれぞれ1つの励起準安定状態しか持たない。 |
