A Comparison of Methods for Determining the Total Efficiency of HPGe Detectors
The total detection efficiency (TDF) of HPGe detectors, calculated using two different codes, MCNP and EFFTRAN, are presented. A comparison with experimentally measured values shows that the two codes produce quite similar results for point sources but very different for disc-shaped ones. Using the TDF calculated with these codes to determine the correction for true coincidence summing (TCS), similar results are obtained. This means that this correction is not highly dependent on the TDF, and it is possible to use EFFTRAN to shorten the calculation time.
