Which factor is NOT listed as influencing the amount of scattered radiation produced?

The amount of scattered radiation produced during a radiographic procedure is influenced by several factors, including field size, radiation quality, and specific patient conditions such as pathology. Field size affects scattering because larger areas expose more tissue and introduce more chances for interactions that lead to scatter. Radiation quality refers to the energy of the x-rays; higher energy levels can produce more scatter due to greater penetration through tissues. Pathology influences scattering as certain conditions may change the density and composition of tissues, which in turn affects how radiation is interacted with and scattered.

Distance from the source, while it does influence the intensity of radiation received by the detector or patient, is not a direct factor in the production of scattered radiation itself. Instead, it alters the amount of primary radiation that reaches the object. Therefore, the option indicating distance from the source is not considered an influencing factor in the actual generation of scattered radiation.
