New Spectral Core Gamma Logger (SCGL) for analysis
Designed for making improved core measurements
New Spectral Core Gamma Logger (SCGL) for analysis
IFE (Institute for Energy Technology) has developed a new Spectral Core
Gamma Logger for analysis of geological cores. ResLab in Norway is the
world-wide distributor of this instrument.

The SCGL is an instrument designed for improved core gamma measurements.
All sedimentary rocks contains natural radioactivity. The SCGL measures the
natural radioactivity present in well cores. The instrument detects total gross
gamma (API units) and elemental contribution of Potassium (%), Uranium (ppm)
and Thorium (ppm). The conveyor belt with electronics and mechanical
components is assembled into a compact and robust system. The system is
delivered ready for use and is equipped with ISAC data acquisition and control
software.

Advantages
•  Measures total gross gamma in counts and API units
•  Large scintillation crystal detector offers enhanced counting efficiency
•  Gain stabilised detector to prevent loss of resolution due to gain drifts in the
    system when making measurements over long time periods
•  Improved signal-to-noise ratio by using extended lead shielding to minimize
    influence from background gamma radiation
•  Supplied with the latest Multi Channel Analyser (MCA) digital technology
•  Windows based data acquisition and control software (ISAC)

ISAC (Ife Scientific Acquisition & Control) Software
•  Data acquisition and reporting software with very low learning threshold
•  Designed for use with Microsoft Windows NT‚ 2000 and XP
•  Standard routines for running calibration cores prior to core measurement
•  Data is saved in ASCII format for easy transfer and post-processing
•  Possible to adjust depth when running measurements to achieve correct
    correlations
•  Spectrum logger facilities with options to save spectrum files for each
    measured depth
•  Variable core logging speed

Options
•  Calibration core standards composed of calibrated concentrations of
    Potassium, Uranium and Thorium
•  200 API standard and Inactive standard
