An empirical method to determine coincidence-summing corrections in gamma spectrometry

We propose an empirical method to calculate coincidence-summing corrections in γ-spectroscopy by comparing the measured areas from the same γ-ray emissions in two different geometries. The method is simple and avoids complicated calculations needed in usual procedures. The applications to two experimental arrangements used frequently for measuring environmental samples is developed and the efficiency calibration in the energy range [46.54, 1410] keV of a HPGe detector is performed for these specific experimental setups.
