Abstract: A borehole logging probe for mineral or petroleum exploration is disclosed having a californium-252 neutron source for activating elements adjacent to the borehole and a solid state detector for sensing resulting radiation. The probe includes an elongated watertight housing having a shielded compartment for the neutron source, and a thermally insulated compartment for containing the radiation detector. A reservoir is filled with a fusible solid cryogen and located within the insulated compartment adjacent to the detector with a thermal conduction member disposed to cool the radiation detector by transferring heat to the solid cryogen.

Abstract: A marine mineral-detection apparatus is described including a 252Cf source of neutrons and a lithium-drifted germanium radiation detector shielded from the neutron source. The neutron source is mounted on an extensible member supported within a mass of neutron-shielding material. The source is extended outside the neutron shield to bombard surrounding mineral values with neutrons. Elements capturing neutrons give off prompt gamma radiation with discrete energies. The radiation detector resolves the radiation into distinct energy peaks for identifying the elements present in the mineral values.
