Abstract
In some embodiments, an apparatus and a system, as well as a method and an article, may operate to receive gamma ray measurements from a gamma ray detector; to generate a spectrum based on the gamma ray measurements, the spectrum including channels and count rates for the channels, wherein a channel number of a channel corresponds to energy values associated with the gamma ray measurements; to generate a ratio of total counts in a first window of the spectrum to total counts in a second window of the spectrum, the first window including a first set of channels starting at a low threshold channel and the second window including a second set of channels; and to adjust a gain of the gamma ray detector responsive to a determination that the ratio is different from a desired ratio. Additional apparatus, systems, and methods are disclosed.
