Most occupational exposure comes from which source?

Explanation:
Scattered radiation from the patient is the main source of occupational exposure. When the primary x-ray beam hits the patient, photons scatter off tissues (primarily via Compton interactions) in many directions, including toward the operator. The direct primary beam is kept out of the operator’s path with distance and shielding, and leakage from the tube housing is tightly controlled and contributes far less in normal practice. Stray radiation encompasses both scatter and leakage, but scatter is the larger contributor to the dose the radiographer receives.
