Holding radiographic film during exposure increases occupational exposure primarily to which body part?

• A. Eyes
• B. Hands
• C. Feet
• D. Nose

Answer: (B)

Holding radiographic film during exposure places the operator’s hands in the closest proximity to the patient and to the scatter produced by the X-ray interaction. Although the primary beam is aimed through the patient to the film, scattered photons radiate in all directions, and the hands that are continually used to position or hold the film endure the highest amount of this scatter. The eyes, nose, and feet are typically farther from the field or shielded by positioning and protective equipment, so they receive substantially less scatter exposure. This is why the hands are the body part most affected when film is held during exposure. Using film holders or keeping hands away from the beam substantially reduces this exposure.
