Isotope Tracing in Natural Systems

 

Hydrology Archaeology Ecology

 

 

Isotope Tracing in Natural Systems (ITNS) is a user focused facility providing a range of radioanalytical, isotopic and elemental analytical techniques, measurements and expertise for environmental studies.

 

The facility undertakes a broad range of analyses for research and industry. The ITNS team can provide customised services to suit the particular requirements of each client.

 

Applications

 

The facilities can be used in a broad range of fields including:

  • Hydrology
  • Ecology and palaeoecology
  • Geomorphology and geochronology
  • Climate and atmospheric science

 

Capabilities

 

  • Dating (Lead-210, Cesium-137, Tritium dating of waters)
  • Low-level alpha and gamma spectrometry for determining radionuclides in environmental samples such water, soil, sediment, vegetation, biota and for radon in air
  • Stable isotope analysis of δ2H, δ18O in waters and δ13C, δ15N and CN% in vegetation and biota
  • X-ray Fluorescence (XRF) core scanning for high resolution elemental distributions, magnetic susceptibility, and optical and radiographic images
  • Elemental analysis, including laser ablation of solids
  • Manufacture of specialised semi-portable detectors for outdoor, continuous, monitoring of ambient radon in air.

 

Facilities

 

  • Environmental Isotope Labs (EIL) equipped with isotope ratio mass spectrometers (IRMS), a Picarro Cavity Ring-Down Spectrometer (CRDS), and a range of sample preparation devices
  • Radon Analytical Laboratory featuring a radon rig, liquid scintillation counter, gamma spectrometer; a flux chamber (emanometer); and field instrumentation
  • Analytical laboratory equipped with a quadrupole inductively coupled plasma - mass spectrometer (qICPMS), a simultaneous inductively coupled plasma atomic emission spectrometer (ICPAES), an anion chromatograph (IC) and a laser ablation unit coupled to the qICPMS or ICPAES for chemical and isotopic composition of solid samples
  • Tritium Laboratory equipped with large and small volume distillation apparatus, 32 electrolysis units and four liquid scintillation counters (LSC) for surface and groundwaters studies
  • Environmental Radioactivity Measurement Centre (ERMC) for low level for the measurement of a wide range of radionuclides, with radiochemical laboratory for processing environmental samples and detectors housed in dedicated instrument laboratories. This laboratory also houses XRF core scanner.
