X-ray scatter primarily depends on photon energy. The energy of the photons influences how they interact with matter. Higher-energy photons tend to penetrate materials more effectively and may interact with tissues differently than lower-energy photons, resulting in varying scattering patterns. This property is crucial in determining how much scatter will be present in an imaging scenario, as it affects both the quality of the diagnostic image and the dose of radiation that may be received by nearby tissues.

In general, while the shape of the substance might play a role in how radiation is distributed, it's not a primary factor affecting scatter on the same level as photon energy. Other factors such as temperature and humidity do not have a significant impact on the amount of scatter produced in X-ray imaging.
