Geoneutrinos confirm that half of the heat from the earth's interior is from the decay of Uranium and thorium

 

 

A main source of the 44 trillion watts of heat that flows from the interior of the Earth is the decay of radioactive isotopes in the mantle and crust. Scientists using the KamLAND neutrino detector in Japan have measured how much heat is generated this way by capturing geoneutrinos released during radioactive decay.
