[en] Three different gamma-ray detection systems for Moessbauer measurements at count rates above 10⁵ s^-1 are described. The first uses the fast output of an uncooled NaI(Tl) scintillation counter and will still provide energy discrimination at total pulse rates up to 10⁶ s^-1. Count rates up to some 10⁷ s^-1 can be handled by a tin-loaded plastic scintillation detector, but only with very limited energy resolution. For even higher photon intensities, the method of current integration is available. The various techniques are illustrated and compared on the basis of measurements with the Moessbauer resonances in ¹⁷⁰Yb (84 keV), ¹⁹⁹Hg (158 keV) and ²³⁷Np
