Kegunaan isotop seng
- Oral tracers of enriched 67Zn and intravenously injected stable isotopic tracers with enriched 70Zn are used simultaneously to determine the fraction of dietary zinc absorbed in humans, maintaining the amount or concentration of a nutrient or biomolecule in organs and body fluids. For example, zinc-isotope tracers can be administered to humans to determine if zinc absorption in their bodies may be impaired by ingestion of certain foods, food components, or dietary supplements. One such study conducted with Peruvian women showed that prenatal iron supplements affected the absorption of zinc during pregnancy. Another isotope tracer study investigated zinc deficiency in children with Crohn’s disease (an inflammatory disease of the intestines, especially the colon and ileum),. Zinc radioisotopes (e.g. 65Zn, with a half-life of 244 days) can also be used for determining zinc absorption in humans, but they are now used rarely because of radiation hazards,. ZnO nanoparticles enriched with 67Zn have been used as biological/environmental nanotoxicity tracers.
- 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.
