Kegunaan isotop tembaga
- The radiopharmaceutical 62Cu-PTSM, which contains radioactive 62Cu (with a half-life of 9.7 min), is used as a tracer in positron emission tomography (PET) to quantify myocardial perfusion (heart blood-flow measurements),. The radioisotope 64Cu (with a half-life of 12.7 h) is used for PET imaging and radiotherapy to diagnose, understand, and monitor disease (Fig. IUPAC.29.2),. The stable isotope 65Cu has been used as a tracer to study copper absorption, utilization, and excretion in humans,.
