| Abstract: | The effect of failing to properly model the rounding of the crystal edges in the application of the efficiency transfer method to the measurement of environmental samples is investigated for coaxial and thick planar (BeGe) HPGe detectors. It is found that for lower energies proper modelling of the crystal rounding is necessary to achieve the accuracy of the computed efficiency usually required in this type of measurements. |
