Copper-64 (Cu) is a positron and beta emitting isotope of copper (exhibiting both forms of beta decay), with applications in molecular radiotherapy and positron emission tomography. Its unusually long half-life (12.7 hours) for a positron-emitting isotope makes it increasingly useful when attached to various ligands for PET and PET-CT scanning.

==Properties== Cu has a half-life of 12.70 hours and decays 61.5% of the time to Ni, of which 17.5% is positron emission and 44% by electron capture, and 38.5% by beta decay to Zn. The electron-capture branch emits a 1.346-MeV gamma ray in 0.472% of all decays, which could be used for tracing the isotope.
