Molecules, atoms, and ions of the stable isotopes of zinc possess slightly different physical and chemical properties, and they commonly will be fractionated during physical, chemical, and biological processes, giving rise to variations in isotopic abundances and in atomic weights. There are measureable variations in the isotopic abundances of zinc in natural terrestrial materials (Fig. IUPAC.30.1). Stable zinc isotopes have been used as tracers to investigate biogeochemical and chemical processes in environmental contamination sites. The isotope-amount ratio n(66Zn)/n(64Zn) can be used as an environmental tracer for detecting the pathways of anthropogenic zinc,,.
The 68Zn (p, 2p) 67Cu (with a half-life of 62 h) reaction in which targets with zinc enriched in 68Zn are irradiated and the neutron induced reaction 67Zn (n, p) 67Cu are both processes for producing 67Cu for radiotherapy. Irradiation of 64Zn with a deuteron (the nucleus of 2H, consisting of a proton and a neutron) in a cyclotron will produce the radioisotope 64Cu (with a half-life of 12.7 h), which can be used for therapeutic applications and diagnosis with positron emission tomography (PET) via the 64Zn (d, 2p) 64Cu reaction.
