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.
