Experimental and Monte Carlo determination of HPGe detector efficiency

Monte Carlo model has been developed using the GEANT code for calculation of the full energy peak efficiency of a HPGe detector operating in the Slovak Institute of Metrology. The model has been used for calculation of the HPGe detector efficiency for gamma-spectrometry measurements associated with...

Description
Summary:Monte Carlo model has been developed using the GEANT code for calculation of the full energy peak efficiency of a HPGe detector operating in the Slovak Institute of Metrology. The model has been used for calculation of the HPGe detector efficiency for gamma-spectrometry measurements associated with the development of a national radon standard. The detector model was validated by comparison of simulated efficiencies with measured experimental values for point sources and for 450 mL Marinelli beaker. A reasonable, up to 5% agreement between the simulated and experimental results was achieved in the energy range from 100 to 1800 keV.
