NGA’s new map characterises Earth’s radioactivity

US: Researchers at the National Geospatial-Intelligence Agency have published a new map that characterises the Earth’s radioactivity and offers new and potential for basic science research and nonproliferation efforts. The map utlises open-source geophysical data sets and publicly available international antineutrino detection observational data to depict varying levels of radioactivity on Earth.

Shawn Usman, NGA R&D scientist and lead author of the study, has stated that the open access availability of antineutrino maps represents the next generation of cartography and provides a sneak peak of the basic understanding about the interior of planet Earth.
