Resumen
In this work, verification data for 11 HPGe detectors from two different manufacturers and three different
intrinsic configurations were analyzed in respect to the stability of both the efficiency and resolution for the
122 keV peak from 57Co and the 1332 keV peak from 60Co. The results allow a discussion about the stability of
these parameters over time (in some cases, almost 15 years), their sensitivity to imminent detector failures and
their performance after a failure has been corrected; moreover, the results show a clear correlation between the
manufacturer or configuration and the long-term performance of the detector.
