摘要：

Simple and practical coincidence summing corrections for n-type HPGe detectors are presented for the common calibration nuclides Co-57 and Co-60 using a defined "virtual peak" and accounting for the summing of gamma photons with x-rays having energies up to 40 key (Y-88 and Ce-139). These corrections make it possible to easily and effectively establish peak and total efficiency curves suitable for subsequent summing corrections in routine gamma spectrometry analyses. Experimental verification of the methods shows excellent agreement for measurements of different reference solutions. (C) 2012 Elsevier Ltd. All rights reserved.
