Beschreibungen/Notizen

• A practical and comprehensive experimental approach for radioactivity measurements of voluminous environmental samples using high-resolution gamma-ray spectrometry with High Purity Germanium (HPGe) detector is presented. The radioanalytical procedure includes sample preparation, detector calibration, implemented corrections, quality control and assurance; and it is demonstrated with the determination of natural and anthropogenic radionuclides in water and soil standard samples. The methodology is verified, and the results are validated by intercomparison with the refence values provided as part of a worldwide proficiency test. •Gamma-spectrometry for routine laboratory measurements of environmental samples.•Experimental calibration of HPGe detector for one solid and two liquid extended geometries.•Wide-energy efficiency estimation using multiple sources and computational methods.•Monte Carlo simulations of calibration spectra and theoretical FEPE calculations.
