Efficiency calibration of high volume samples using the GESPECOR software.
In this paper the Monte Carlo simulation program GESPECOR is applied for the computation of the efficiency of an HPGe gamma-spectrometry system used for the measurement of high volume samples. The detector characterization required for Monte Carlo simulation is achieved by a trial and error procedure using the efficiency values measured with point sources placed in several positions. After detector characterization, the efficiency values appropriate for the assessment of 220l waste drums are computed and compared with experimental values.
