Portable gamma ray

Geofactory offers a gamma-ray spectrometry for geological core logging. This BGO 2”X 2” crystal detector and lead shielding should be used for focused measurement of cores or for stratigraphic measurements. Using internal constants based on IAEA traceable calibration pads, the Portable Gamma Logger can compute precise rock concentration of K (%), U and Th (ppm). Results are displayed immediately after end of measurements. They will be stored in the instrument and/or sent to appropriate external devices via Bluetooth or Wi-Fi. It also uses an advanced method of automatic stabilization on natural background radiation throughout its operation. This unique stabilization method eliminates the need for an additional radioactive check source. Result available in Spectral, Total and API Conversion.
