Description

Radioactive decays are responsible for approximately 40% of the Earth’s total heat flow. The geo-neutrinos produced by these decays provide important clues about the origin, formation and thermal evolution of our planet, as well as the composition of its interior. Since existing measurements of geo-neutrinos are all non-directional, they do not provide model-independent information about the location or spatial distribution of geo-neutrino sources within the Earth. In this poster, we explore the potential for directional geo-neutrino measurements to reveal the geo-neutrino contribution from the mantle. We calculate the exposure and angular resolution needed to probe mantle geo-neutrinos for various sites around the world. Finally, we discuss the implications of these measurements on long-range nuclear monitoring.
