n: Schlumberger/Anadrill LWD tool that measures resistivity at two depths of investigation. Also measures spectral gamma ray to give relative proportion of potassium, thorium, and uranium.

n: a special gamma ray log that reveals the relative amounts of radioactive uranium, thorium, and potassium in a formation. This information can help identify shales and clays.

n: schlumberger wireline tool that breaks down the naturalgamma rayspectrum to differentiate between minerals such as potassium, thorium and uranium. Useful for reservoir declieaqtion, well to well correlation, cation exchange capacity studies,igneous rock r

NORM scale, usually barium or strontium sulfate scale with very low level radiation from atoms of uranium, thorium and potassium in the matrix of the scale.

n: the property possessed by some substances (such as radium, uranium and thorium) of releasing alpha particles, beta particles, or gamma particles as the substance spontaneously disintegrates.

gamma ray tool which splits the spectral range into three parts: uranium, potassium and thorium.

n: a radioactive metallic element found combined in minerals.

Th232, one of the natural isotopes that as a trace element may incorporate into the matrix of naturally forming barium or strontium sulfate scale and make it a very low level radioactive material (NORM scale).
