JFS-2 Borehole Gamma Logging Equipment And Tools
In boreholes, the JFS-2 tool assesses the levels of naturally occurring gamma radiation within the surrounding rock layers. These emissions predominantly result from the decay of potassium, thorium, and uranium isotopes. Gamma logs produced using the JFS-2 are indispensable in groundwater and mining sectors, where they help determine lithological characteristics and conduct thorough clay content assessments. This data is vital for understanding subsurface geology and managing resources effectively.
