How much uranium is in the earth's crust
Nettet29. aug. 2005 · We present a prediction for the geo-neutrino signal at KamLAND as a function of the uranium mass in the Earth. The prediction is based on global mass balance, supplemented by a detailed geochemical and geophysical study of the region near the detector. The prediction is weakly dependent on mantle modeling. NettetWith the huge amount of seawater on earth, there is over 600 times more U in the sea than the on land U deposits. With 1) and 2) too, this would extend the number to ~500k years. There is also a lot of U in Earths crust (65 trillion tonnes of it!!!), which will over time erode into seawater. The 4 billion years number comes from assuming half ...
