What is the minimum distance recommended for dental personnel to stand from the x-ray source during exposure?

The recommended minimum distance for dental personnel to stand from the x-ray source during exposure is 6 feet. This distance is established to reduce radiation exposure and protect the health of dental staff. At this range, the intensity of scatter radiation decreases significantly, allowing for maximum safety while still being able to monitor the procedure.

Standing beyond this distance minimizes the risk of radiation exposure, as the inverse-square law dictates that the intensity of radiation decreases with the square of the distance from the source. Thus, being at least 6 feet away is aligned with safety protocols and regulatory guidelines, ensuring that dental personnel maintain a safe working environment while performing necessary imaging procedures.
