Antineutrinos from uranium, thorium, and potassium decay deep within the Earth provide direct measurements of Earth's interior heat production — a kind of neutrino tomography.
From a converted Japanese mine, a 1,000-ton tank of liquid scintillator caught reactor antineutrinos from 53 power plants across Japan and Korea. Its 2003 result established that reactor neutrinos oscillate at exactly the rate the solar neutrino problem predicted.
Inside an Italian mountain, a 280-ton sphere of the purest liquid ever made by humans listened for two decades to the quiet hum of solar neutrinos — and finally caught the CNO cycle in 2020.
About half of Earth's internal heat comes from radioactive decay. Geo-neutrino experiments at KamLAND and Borexino are slowly turning that fact into a measurement — and revealing the planet's hidden chemistry.
