Abstract No single method is able to clarify all the problems raised in the deep- hole logging operations. Determination of many properties such as specific resistivity, potential of induced fields, heat conductivity, dielectric constants, etc., is to differentiate between minerals. Radioactivity measurements are very useful because they can be performed in steellined drill holes which would affect other measurements. The neutron- measurements, which involve the determination of the energy of the quantum resulting from the inelastic interaction between the neutron radiation and the atoms of the material, are widely employed. Thus the data obtained from measuring the intensities obtained when a neutron source and a detector are introduced into the hole determine directly the atomic number, the mass number, and the cross section of the elements in the surrounding minerals, giving their approximate composition. Despite the technical difficulties, scintillation counters are better suited for this type of measurement than G-M counters. (TTT)
