Abstract

Natural gamma ray logs are indicating the concentration of thorium (Th), uranium (U), and potassium (K) in the rocks surrounding a borehole and they are a measurement of the natural radioactivity of the formation. The energy of the gamma-rays (photons) differs for Th, U, and

K. Potassium emits only gamma photons of energy 1.46 MeV. Thorium emits gamma photons of a number of different energies, the highest of which is 2.62 MeV. Uranium similarly emits gamma photons of a number of different energies with 1.76 MeV as the highest energy that can be detected in a borehole. Here the values indicate total gamma ray energy and are function of well depth.

citation	The following acknowledgment should accompany any publication or citation of these data: Logistical support and/or data were provided by the NSF-supported Shale Hills Susquehanna Critical Zone Observatory.
comments	Wire-line logging: The natural gamma log system consists of a gamma ray detecting probe, geophysical logging cable and a digital counter instrument. It is done by lowering the probe down the drill hole and recoding the gamma radiation variation (in count-per-second) with depth (in meters). Two data sets for each well: Down and Up. Down: From top of the well to bottom of the well. Up: From bottom of the well to top of the well. Depth in meters in first column and gamma radiation variations in count-per-second in the second column.
