Integral spectrometers measure the total amount of incoming gamma radiation that lies above a certain energy threshold. In order to emphasize the smaller peaks, the spectrum in this figure is shown on a logarithmic scale. This circle defines the area from which a given percentage of the total terrestrial radiation that is received by a stationary detector at a given height above ground originates. Using an example from Grant, 1982, I'll try to illustrate detector selection with specific examples. These systems are illustrated in Figure 3.2-1.

4.5c Detector Selection . Thus, in principle, if we measure gamma ray spectra over different regions of exposed rock, and compare them, we should be able to translate changes in the heights of the 1.46, 1.76 and 2.62 MeV peaks into corresponding variations in the concentrations of potassium, uranium, and thorium within the different rock types.
