Thorium Uranium Potassium

Consulting Potential Field Geophysics, Airborne Gamma-Ray

The uranium and thorium content of rocks generally increases with acidity, with the highest concentrations found in pegmatites. This relationship is illustrated in appendix 1. The highest concentrations of uranium and thorium in sedimentary rocks usually occur in shales. The potassium content of rocks also increases with acidity.

Gamma ray logging Wikipedia

Gamma ray logging is a method of measuring naturally occurring gamma radiation to characterize the rock or sediment in a borehole or drill hole. response to natural gamma ray radiation is usually presented as a total gamma ray log that plots the weight fraction of potassium (%), thorium (ppm) and uranium (ppm). The primary standards for the

Isotopes of Uranium Nuclear Power

232 U is a side product in the thorium fuel cycle and also this isotope is a decay product of 236 Pu in the uranium fuel. 232 U decays via alpha decay to 228 Th with half-life of 68.9 years. 232 U very rarely decays by spontaneous fission. Its specific activity is very high ~22 Ci/g and its decay chain produces very penetrating gamma rays.
