Imaging the Earth's Interior with Geo-neutrinos


  • Radioactive decay of U and Th gives off ghost-like, neutrino particles that can be detected by 1000 ton detectors built a mile underground, where they are shielded from the cosmic rays that rain down on the Earth. Collaborations between physicists and geologists are detecting these "geo-neutrinos". Future underwater detectors, deployed at different points on the ocean floor, will create a neutrino tomographic image of mantle structures sited at the base of the mantle above the core.
