Abstract
A simple method is presented for calibrating HPGe detectors used for whole-body counting by transfer of calibration data from one detector to another. The method can be used for calibration of high purity GE detectors (HPGe) in various counting geometries such as detector-body surface distance or for various dimensions of anthropomorphic phantoms. The calibration method has been verified for HPGe detectors with relative efficiencies of 12.5% and 61.8% (relative to 7.6 x 7.6 cm NaI). In comparison with precise calibrations (by phantoms and/or Monte Carlo calculations) the calibration method by data transfer yields results with differences up to 25% for photons in the energy range from 0.15 MeV to 1.5 MeV.
