1. Measuring apparatus for quantitatively measuring the concentration of an element in a sample containing said element, said apparatus comprising a neutron inelastic scatter assembly, a γ

  • ray scatter assembly and means to calculate said concentration from the outputs of said assemblies, said assemblies being matched to measure over essentially the same volume of said sample, said neutron inelastic scatter assembly comprising a first source yielding neutrons having energy sufficient to produce inelastically scattered first γ

    rays from a stable insotope of said element, a first detector to detect said first γ

    rays, and first shield means associated therewith to reduce the intensity of direct source, radiation, said γ

    ray scatter assembly comprising a second source yielding second γ

    rays, a second detector to detect said second γ

    rays scattered from said sample, and second shield means associated therewith to reduce the intensity of direct source γ

    rays.
