Monte Carlo Determination of Full Energy Peak Efficiency for HPGe Detector and Self-Absorption Correction of Environmental Samples
The Monte Carlo method was used to determine full energy efficiency of a high-purity germanium (HPGe) coaxial detector within an energy range of 53.2-2614 keV. Also, measurement was carried out for a standard Marinelli beaker of 600cm3, which was placed into the reference material of mixed gamma. The plot of the experimentally derived effic...

Analyzes of environmental samples regarding their radioactivity is of important concern for health purposes. We need standard sources to determine radioactive components and their activities. These sources are usually produced regarding type of the sample. One of the fundamental and precise tools to recognize radioactive materials and their activities is HPGe detector. To reach this goal, the d...
متن کاملDetermination of Primordial Radionuclides in Natural Samples Using HPGe Gamma-Ray Spectrometry
Distributions of primordial radionuclides in soil and vegetables were investigated using high-purity germanium gamma-ray spectrometry. Gamma-ray spectrometry is one of the most accepted and widely used techniques for the detection and analysis of radioactive materials for a wide range of activity. Important properties of the employed gamma-ray detector were also determined to ensure the accurac...
متن کاملDetermination of virtual point for HPGe detector at various gamma rays energies by simulation and experimental methods
High Purity Germanium detectors (HPGe) are subdivisions of semiconductor detectors which are widely used in nuclear technology from space industry to nuclear medicine, due to their high resolution, low dead time, unlimited size and compatibility with a variety of environments. The( absolute and intrinsic) efficiency of the HPGe detector, which depends on the geometry of the source-detector syst...
