Nuclear logging apparatus

Nuclear logging apparatus

Nuclear logging apparatus includes a lithium detector (14, 16) for detecting neutrons emitted from a borehole formation. Data processing means are provided for analyzing the pulse amplitude spectrum developed by the detector, to thereby derive and strip a gamma-ray background from the detector spect...
