JFS-2 3000M Water Well Equipement Gamma Resistivity Well Logging Tool Geophysical Borehole Logger
JFS-2 Natural Gamma Probe
Description
The JFS-2 probe quantifies the natural gamma radiation emitted from rock formations encountered in a borehole. This radiation primarily originates from isotopes of potassium, thorium, and uranium. Widely utilized in groundwater and mining sectors, the gamma log serves to determine lithological characteristics and conduct clay content analysis.
Revised Description
The JFS-2 probe measures the natural gamma radiation levels present in the geological formations traversed by a borehole. These gamma rays are predominantly generated by isotopes such as potassium, thorium, and uranium. In the fields of groundwater management and mining, this tool is extensively employed to identify rock types and assess clay content within the formations.
Alternative Phrasing
Designed to measure naturally occurring gamma radiation in borehole environments, the JFS-2 probe detects emissions from potassium, thorium, and uranium isotopes within the surrounding rock layers. Commonly used in hydrogeology and mining applications, it aids in identifying lithological features and analyzing clay composition.
Extended Version
The JFS-2 probe is engineered to gauge the intensity of naturally occurring gamma radiation within the rock formations intersected by a borehole. The primary sources of this radiation are isotopes of potassium, thorium, and uranium. This instrument is indispensable in both groundwater studies and mining operations, where it plays a crucial role in determining lithological properties and conducting thorough clay content evaluations.
