摘要：
The measurement of the gamma-ray emission probabilities per decay of 1077 key of Ga-68 is presented. The standardization system consists of a gas-flow proportional counter in 4 pi geometry coupled to an HPGe detector for the gamma-ray detection. The gamma-ray emission probabilities per decay were measured in an HPGe gamma-ray spectrometer. The weaker gamma-ray intensities of Ga-68 were measured in a relative way, making use of an uncalibrated ampoule of Ge-68-Ga-68 in radioactive equilibrium, and considering the absolute result from the 1077 keV gamma-ray.
