WebFeb 1, 2004 · Abstract: The nuclide 67 Ga is widely used in nuclear medicine for diagnostic purposes. It decays with a half-life of 3.259 days to 67 Zn, a stable nuclide. The decay mode is elec WebThe recommended adult (70 kg) dose of Gallium Citrate Ga 67 Injection is 74-185 MBq (2-5 mCi). Gallium Citrate Ga 67 Injection is intended for intravenous administration only. Approximately 10% of the administered dose is excreted in the feces during the first week after injection. Daily laxatives and/or enemas are recommended during the first ...
