Which action is a recommended safety precaution during radiographic exposure?

• A. Stand behind barrier
• B. Hold the film in the patient's mouth if necessary
• C. Stabilize the tube head during radiation
• D. Expose without shielding

Answer: (B)

The main idea here is protecting everyone from radiation by using shielding and distance during dental X-ray exposure. The safest and most effective action is to position yourself behind a lead barrier, or as far away from the primary beam as possible, so scatter radiation is greatly reduced. This keeps your hands and body out of the path of the beam and minimizes exposure. Holding the film in the patient's mouth is not a recommended safety practice. It requires someone to place hands close to the beam and the patient’s mouth, which increases the likelihood of hand exposure and can lead to more retakes if the image isn’t positioned correctly. Using a film holder or otherwise stabilizing the film without having someone hold it with their own hands is preferred to eliminate this risk. Stabilizing the tube head is important for image quality and reduces the chance of repeated exposures due to movement, but it does not by itself protect against radiation to the operator. Exposing without shielding is obviously unsafe.
