Designed for quantitative determination of natural radioactive elements (NRE) content - uranium (U), thorium (Th) and potassium (K) - in rocks during the study of wells for various purposes, drilled in solid mineral deposits and groundwater.
The downhole tool is to be run with VULCAN V3 log recorder or similar.
Operates with one-core or three-core logging cable.
