Which factor does NOT contribute to nonuniform dose distribution within the body during radiography?

Explanation:
Internal scattering spreads energy in many directions as photons interact with tissues, which helps smooth out sharp differences rather than create them. The big ways to make dose vary within the body are shaping the primary beam and using shields: restricting the beam and placing shielding carve out regions of higher dose inside the field and lower dose behind shields or at the field edges, and tissue heterogeneity adds to those variations. Because scattering tends to distribute energy more evenly, it does not drive the nonuniform patterns as strongly as beam restriction and shielding do.
