For example, a geoneutrino detector would ineluctably record a signal from a galactic supernova over a few seconds. Other types of extremely infrequent astrophysical phenomena (such as a burst of neutrinos associated with a GRB event), may also be recorded, without interference with geoneutrino ...
210 Ma, to generate the observed isochron. Such resetting cannot have caused the complete loss of structurally bound common Pb in the apatite or else the initial 207Pb/206Pb ratio would have decreased to <0.9, as would be predicted for Triassic crustal fluids. Hence, the c. 210 Ma ...
The main antineutrino background in the geoneutrino measurements results from nuclear power plants, while negligible signals are due to atmospheric and relic supernova . Other, nonantineutrino background sources can arise from intrinsic detector contaminations, from random coincidences of noncorrelated ...
