Abstract: Geo-neutrino detection can determine the amount of long-lived radioactive elements within our planet, thus providing a direct test of the Bulk Silicate Earth (BSE) model and fixing the radiogenic contribution to the terrestrial heat. 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. If BSE is correct, Uranium geo-neutrinos will produce between 25 and 35 events per year and 10^32 protons at Kamioka.
Comments: 25 pages, 5 figures; minor changes in reply to referees' comments and APS style requirements, version to appear in PRD. In particular, one less figure, Table III and Table IV have been exchanged and last figure is now first to be referenced in order, note added in proofs on recent KamLAND results
