Beta-gamma-coincidence spectroscopy is a sensitive measurement technique in reactor neutron activation analysis. A simple counting device with a 4″×3″ NaI(Tl) crystal and a 32 mm×2 mm plastic scintillator is described and the advantage of the β-γ-coincidence technique, which has been successfully applied to the determination of iron and other impurities in semiconductor silicon, is discussed.
