The U-Th radioactive disequilibrium measurements with Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS) were applied to a coral reference; JCp-1 distributed by the Geological Survey of Japan to evaluate homogeneity of the standard material. The two times of standard deviations (2SDs) of [U/U]isotope ratio, [ U/U]isotope ratio, U abundance, [ 230Th/ Th]isotope ratio, and T...

We nd that recent results from the KamLAND collaboration on geologically produced antineutrinos N U Th events correspond to a radiogenic heat production from Uranium and Thorium decay chains H U Th TW The con dence limit on the geo neutrino signal translates into the upper bound H U Th TW which is much weaker than that claimed by KamLAND H U Th TW based on a too narrow class of geolog ical mode...
