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. NettetUranium. Uranium is a trace element that occurs naturally in the earth's crust. All of the isotopes of uranium are unstable and are radioactive. The most abundant isotopes are 238 U and 235 U. The percentage abundance of 238 U is 99.25 percent and the abundance of 235 U is 0.75 percent. california gray wolf https://lynnehuysamen.com
