Mount-Sopris - Model QL40-GR -Natural Gamma Probes
The QL40-GR probe measures the amount of gamma radiation occurring naturally within the formations crossed by a borehole. Gamma rays are produced mainly by isotopes of potassium, thorium, and uranium. The gamma log is widely used in the groundwater and mining industries to identify lithology and perform clay content analyses. The tool is supplied as a stackable sub of the Quick Link (QL) product line or it can be run as a standalone tool. The QL40-GR operates on any standard wireline (mono, 4 or 7 conductor, coaxial).
