Abstract

An internal consistency test of the calculation of coincidence-summing correction factors F-C for volume sources is presented. The test is based on exact equations relating the values of F-C calculated for three ideal measurement configurations. The test is applied to a number of 33 sets of F-C values sent by 21 teams. Most sets passed the test, but not the results obtained using the quasi-point source approximation; in the latter case the test qualitatively indicated the magnitude of the bias of F-C.
