Determination of full energy peak efficiency of HpGe detector from 59.5 to 1332.5 keV

Abstract

To detect very low radio activities in the environmental samples, it is sometimes necessary to know the full energy peak efficiency of the detector. This work proposes a full energy peak efficiency simulation which represents adequately the high purity germanium coaxial detector responses in the energy range 59.5-1332.5 keV and at distances of 5, 10 and 25 cm.
