Abstract
A downhole tool can include a photon beam source configured to transmit a photon beam into materials lining a wellbore. The materials may comprise fluid, casing, and cement. A photon detector in the tool is configured to count detected photons received at a predetermined angle from the materials. The density of the borehole material may be determined in response to the number of detected photons. Changes in a distribution of a plurality of photon count ratio values may indicate the standoff distance. Additional apparatus, systems, and methods are disclosed.
