Ga half life

A germanium-68/gallium-68 generator is a device used to extract the positron-emitting isotope Ga of gallium from a source of decaying germanium-68. The parent isotope Ge has a half-life of 271 days and can be easily utilized for in-hospital production of generator produced Ga. Its decay product gallium-68 (with a half-life of only 68 minutes, inconvenient for transport) is extracted and used for certain positron emission tomography nuclear medicine diagnostic procedures, where th… WebThe convenient half-life of 68Ga (T1/2=68 min) provides sufficient radioactivity for various PET imaging applications, while delivering acceptable radiation doses to patients.
