Correlation between the range of γ-ray spectrum and energy channels in a γ-ray spectrum.

<p>The ordinate represents the depth variation of the energy spectrum of γ-ray photons. The abscissa lower axis shows the energy of γ-ray photons, while the abscissa upper axis represents the energy channels of the γ-ray spectrum across the 300-meter lacustrine sediment of Lake Chalco. The color bar indicates the detected energy levels. Additionally, the γ-ray signal is illustrated across the depth.</p> <p>(DOCX)</p>
