What is recorded here?
KamLAND analyzed low-energy antineutrino candidates to investigate uranium- and thorium-chain radioactivity inside Earth. With an assumed thorium-to-uranium mass ratio of 3.9, its spectral fit gave a 90% confidence interval of 4.5–54.2 geoneutrino events and an Earth-model-dependent upper limit on uranium- and thorium-decay heat.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The 152 candidates include substantial reactor and detector backgrounds; individual events were not uniquely tagged as geological. The quoted 60 TW radiogenic-power bound is at 99% confidence under the paper’s reference Earth model, while the event interval is at 90%; potassium-40 antineutrinos lie below the detector threshold. The early constraint is not a measurement of all terrestrial heat or a direct three-dimensional map.
