Radiometric Mapping
1024-channel gamma-ray spectrometry mapping potassium, uranium, and thorium concentrations for uranium exploration, lithology classification, and environmental baseline studies.
The Radioactive Fingerprint of Saudi Geology
Naturally occurring potassium, uranium, and thorium emit gamma rays at distinct energy windows. Mapping their relative concentrations from the air produces a lithological fingerprint of the top 30 cm of soil — distinguishing granite from basalt, fresh outcrop from weathered cover, and pinpointing uraniferous zones invisible to magnetic or EM methods.
Air Solutions operates a 16-litre scintillator pack with 1024-channel spectrometers, calibrated against reference test pads, and corrected for altitude, atmospheric radon, and aircraft background using full-spectrum analysis (FSA) — not the older windows method, which loses sensitivity in low-count environments.
Outputs include K-equivalent percentage, eU and eTh concentration grids, Th/K and U/Th ratio maps, and ternary RGB compositions — all calibrated against reference test pads and validated through ground spot-checks with portable spectrometers.
Applications
Map the Geochemistry From Above
Spectrometry pairs naturally with magnetic and EM data — combined surveys reduce per-km cost and amplify interpretation power.
