Natural Gamma Tool

The Natural Gamma Tool is an essential instrument for measuring naturally occurring gamma radiation in rocks and sediments. By detecting gamma radiation emitted by minerals containing Potassium-40, Uranium-238, and Thorium-232, this tool provides invaluable data for geological and environmental studies.

Argillaceous formations such as shales, mudstones, and siltstones often exhibit high concentrations of potassium-rich minerals, which produce stronger responses on the natural gamma log. This makes the Natural Gamma Tool ideal for identifying and analysing these formations with precision.

  • Accurate Detection: Measures gamma radiation from naturally occurring isotopes for reliable data.
  • Versatile Application: Ideal for geological mapping, resource exploration, and environmental investigations.
  • Responsive Logging: Provides clear readings for formations with varying mineral compositions.
  • Dimensions: 700mm (length) x 38mm (diameter)
  • Weight: 3.5kg
  • Detector Size: 25mm x 50mm
  • Maximum Temperature: 80°C
  • Maximum Pressure: 20 MPa


  • Minimum Diameter: 50mm
  • Environment: Suitable for dry or fluid-filled boreholes
  • Lining: Compatible with unlined, steel, or plastic-lined boreholes

Enhance your geological and environmental studies with the Natural Gamma Tool, designed for accurate, efficient, and reliable subsurface analysis. Whether you’re working on resource exploration or geological mapping, this tool delivers the precision and performance you need.
