Prior to exposure in mobile radiography, which safety statement is correct?

• A. Gonad shields must be worn on all patients
• B. All individuals in the room, except the patient, must be well away from the primary beam
• C. Only patient needs shielding
• D. All individuals must wear protective aprons

Answer: (B)

The main idea is to minimize exposure to anyone other than the patient by keeping them out of the path of the primary beam or behind suitable shielding. In mobile radiography, distance is a powerful protector: the farther someone is from the beam, the dramatically lower their dose (inverse square law). Therefore, keeping all nonessential personnel away from the primary beam during exposure is the safest and most practical approach.

Gonad shielding and wearing aprons are considerations, but they aren’t universally required for every patient or for every person in the room, especially if shielding would interfere with the exam or if the staff can stay behind a barrier or at a safe distance. So the best safety statement is to ensure others are well away from the primary beam during exposure.
