Geo-neutrino flux calculation

Observation of terrestrial antineutrinos provides information on the origin, composition, and thermal evolution of the earth. Comparing the measured flux of terrestrial antineutrinos with the modeled flux constrains the quantity and distribution of uranium and thorium, the main heat-producing elements within the earth. Because the flux is dominated by nearby crustal material, detailed studies of the local geology are essential to a refined understanding of the bulk earth. This contribution outlines the calculation of the terrestrial antineutrino flux.
