What is the relationship between operator exposure to scattered radiation and patient dose?

Explanation:
Operator exposure to scattered radiation tracks with how much scatter the patient produces. Scatter photons come from interactions inside the patient when the primary beam deposits energy there; more patient dose means more photons scatter, and with the same distance and shielding, more of that scatter reaches the operator. So the operator’s dose increases in direct proportion to the patient dose—doubling the exposure to the patient tends to double the scatter reaching the operator. You can reduce operator exposure by increasing distance, using shielding, and keeping the field tight to limit scatter.
