Abstract

In some embodiments, an apparatus and a system, as well as a method and article, may operate to detect gamma radiation as detected gamma radiation, and to determine a relative level of potassium decay energy within a selected band of energy levels, with respect to a combination of at least two of potassium, uranium, or thorium. Further operations may include adjusting at least one of a detector supply voltage or an analyzer gain to place the potassium decay energy at a selected energy level location when the relative level of potassium decay energy exceeds a predetermined threshold, the threshold based on an energy level of a combination of detected gamma radiation within the selected band of energy levels. Additional apparatus, systems, and methods are disclosed.
