5028 Block 1 (Southwest): Reduced Radiometric Point-Located Data from 2024

415,090 line-kilometres of reduced radiometric point-located data were acquired in 2024 by the WA Government. The data, processed with noise filtering and corrections for background radiation and height attenuation, measures concentrations of potassium, uranium, and thorium in the ground surface. It was collected at 100m line spacing and 50m terrain clearance.

Use Cases

• Geological mapping based on natural gamma-ray variations from potassium, uranium, and thorium.
• Mineral exploration targeting deposits associated with specific radioelement signatures.
• Environmental studies assessing natural background radiation levels.
• Creating geophysical models of the Earth's surface using processed radiometric data.

Strengths

• Data volume is substantial, covering 415,090 line-kilometres.
• Processing is detailed, including NASVD filtering, background corrections, and levelling.
• Acquisition parameters are specified: 100m line spacing and 50m terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified; last metadata update was 2026-05-14.
