Abstract
Geoneutrinos are produced by radioactive decays of long-lived isotopes, such as uranium, thorium,
and potassium, within the Earth. Consequently, the geoneutrino flux depends on the abundance
and distribution of these radioactive elements throughout the planet. By measuring this flux,
we gain critical information not only for particle physics but also for geology, as geoneutrinos
provide a unique tool to investigate the Earth’s radiogenic power and composition. To date, two
experiments, KamLAND (Kamioka Liquid Scintillator Antineutrino Detector) and Borexino, have
successfully detected geoneutrinos. The Jiangmen Underground Neutrino Observatory (JUNO),
currently under construction in southern China, represents a next-generation experiment. With
its large volume and high-precision measurement capabilities, JUNO will enable unprecedented
measurements of the geoneutrino flux. This work presents the predicted geoneutrino signal at
JUNO and evaluates its sensitivity to the total geoneutrino flux.
