Vinci Technologies Gamma Ray Logger (NGR 200)

The NGR200 core gamma ray logger provides both total and spectral analysis of the natural gamma radiations emitted from the core samples upon arrival at the laboratory. It permits to differentiate uranium, thorium and potassium concentrations.  The data obtained with this apparatus can be used to adjust the depth of the core to coincide with the open-hole logging depths and to identify zones where core has been lost. The apparatus consists of a conveyer for moving core, lead shielding to reduce background gamma radiation and a suitable gamma ray detector. The detector system consists of a shielded scintillation crystal coupled with a photo multiplier.  Signals from the detector are processed using a multi channel spectrum analyzer and analytical software. The gamma ray events are energy - sorted and counted over three energy windows K, U and Th as well as the total gamma radiation. Core samples can be in barrel, in a fiberglass, or aluminum, liner or exposed. The core is scanned along its length from bottom to top simulating a wire-line log pass. The logging speed is adjustable to suit the core and data requirements
