What is the minimum distance an operator should stand from the patient during mobile radiography according to NCRP Report No. 102?

The correct answer highlights that the minimum distance an operator should maintain from the patient during mobile radiography is 2 meters, as specified in NCRP Report No. 102. This recommendation is based on the principles of radiation safety and the need to minimize exposure to ionizing radiation for personnel operating radiographic equipment.

Maintaining a distance of 2 meters effectively reduces the operator's exposure to scatter radiation that occurs during the imaging process. This distance takes into consideration the attenuation of radiation intensity with distance, which follows the inverse square law; as you move away from the source of radiation, the exposure level decreases significantly. By adhering to this guideline, operators can significantly lower their risk of radiation exposure and enhance their safety while performing mobile radiography procedures.

Understanding this distance requirement is crucial for healthcare professionals as it reflects the best practices for ensuring safety in environments where radiation is present, reinforcing the importance of personal protective measures in clinical settings.
