The safe distance from a digital x ray machine dental depends on several factors, including the machine's settings, shielding, and the type of X-ray being performed.
However, as a general guideline, individuals who are not essential for the X-ray procedure should maintain a distance of at least 6 feet (about 1.8 meters) from the X-ray source during operation to minimize radiation exposure. Additionally, proper shielding and collimation techniques should be used to further reduce scatter radiation.
