Chemical analysis of planetary surfaces is necessary for the understanding of the origin and evolutionary processes of the solar system. We are presently studing the possibility of using a compact 14 MeV neutron generator for geochemical analysis of planetary surfaces, comets and astroids. This method allows the determination of bulk chemical compositon, even in the presence of an atmosphere. This would be possible on the surface of Venus, for example, where alternate methods such as sample return are impractical. Excellent capture gamma-ray spectra have been produced using 252.Cf as a neutron source for environmental studies, as a preliminary investigation related to future planetary exploration. Environmental samples analyzed include suspended and bottom sediments from the Rappahannock River in Virginia.
