For precise determination of γ-ray emission probabilities of short-lived nuclides whose half-lives are less than a few minutes, a β-γ coincidence measurement system has been developed which uses a plastic scintillator as a β-ray detector. The system was applied to a measurement of the absolute γ-ray emission probability of 1,779 keV γ ray in 28Al (T1⁄2=2.24 min), whose γ-ray emission probability is well known. The uncertainty of the measured γ-ray emission probability was smaller than 2%. Performance of the β-γ coincidence system has been demonstrated for a short-lived nuclide, and the details of the corrections have been analyzed.
