Radiometry

Methods

  • Gamma Spectrometry
  • Alpha Spectrometry
  • Liquid-Scintillation Spectrometry

Equipment

Germanium detectors with low-activity lead shielding

  • Two High-purity Germanium well detectors with offset preamplifier and U-style cryostat configuration (Canberra)
  • One High-purity Germanium Broad-Energy Germanium detector with offset preamplifier and vertical cryostat configuration (BE series, Canberra)
  • One High-purity Germanium coaxial detector with vertical cryostat configuration (GEM series, EG&G ORTEC)

Alpha Spectrometer

Alpha Analyst (Canberra) with eight A-series PIPS detectors

LSC-Spectrometer

Triathler (HIDEX, Finland), portable instrument for lab- and field-measurements with lead shielding of the measuring chamber, α-liquid scintillation counting on the basis of α/β-discrimination.

Applications

  • Radiometric dating of lake sediments
  • Detection of groundwater inflow into surface waters on the basis of Radium-226 and Radon-222 measurements
