Koper-62 of 62Cu is een onstabiele radioactieve isotoop van koper, een overgangsmetaal. De isotoop komt van nature niet op Aarde voor.
Koper-62 ontstaat onder meer door het radioactief verval van zink-62.
Radioactief verval
Koper-62 vervalt door β+-verval naar de stabiele isotoop nikkel-62:
![{\displaystyle {{\mathrm {^{~62}_{29}Cu} }{}\mathrel {\longrightarrow } {}{\mathrm {^{~62}_{28}Ni} }{}+{}{\mathrm {e^{+}} }{}+{}{\mathrm {\nu } }{\vphantom {A}}_{\smash[{t}]{e}}}}](https://wikimedia.org/api/rest_v1/media/math/render/svg/df2b3c428d52e09a67cb6a36a6542cc661b592bb)
De halveringstijd bedraagt 9,7 minuten.
