Testing the equivalence of several algorithms for calculation of coincidence summing corrections.

Five different numerical algorithms used for calculating coincidence summing corrections (CSCs) in HPGe gamma-spectrometry in case of complex radionuclide decay schemes were tested for their equivalence. Simulated point-source detection geometries and efficiency curves have been used to calculate and compare counting rates as well as CSCs of (133)Ba, (134)Cs and (152)Eu of 1MBq sources. Contributions of one X-ray per radionuclide were included. The algorithms were found to give identical results within their respective presuppositions.
