How does operator exposure to scattered radiation relate to the dose received by the patient?

Explanation:
Scatter from the patient is the main source of occupational exposure, and its amount scales with how much dose the patient receives. When technique increases patient dose—more mAs, higher kVp, a larger field, or a thicker patient—the number of photons that scatter also increases, so more of that scattered radiation reaches the operator. If distance and shielding are kept constant, the operator’s exposure rises in direct proportion to the patient’s dose. Distance and shielding can reduce exposure, but they don’t change the basic relation: more patient dose means more scatter reaching the operator.
