It is estimated that each pole may contain up to one billion tons of frozen water ice spread throughout the soil. The polar regions that border the permanently shaded craters are also in the sunlight 80-85 percent of the time and would make optimal space station sites. The stations would have access to the water-ice and the sunlight would provide solar power. And by being near the poles you see Earth most of the time, which means you can communicate. The Alpha-Particle Spectrometer measured radon and polonium gasses that escaped from below the surface through conduits created by tectonic, or Moonquake, activity.
Polonium is a decay product of radon, which in turn is a decay product of uranium.
When detected, they both indicate the presence of uranium. Elphic presents a poster on computer simulations used to model neutron emissions from the surface, their flight into space and their detection by Lunar Prospector spectrometers. If they didn't it would have raised doubts about our data. Los Alamos' Lunar Prospector team of the Space and Atmospheric Sciences Group submitted 15 abstracts to the conference and is represented by nine scientists presenting both posters and talks and attending meetings.
