What is the correct distance for a dental professional to stand from the X-ray tube during exposure?

The correct distance for a dental professional to stand from the X-ray tube during exposure is at least 6 feet (2 meters). This distance is primarily based on the principles of radiation safety, particularly the inverse square law, which states that as the distance from a radiation source increases, the intensity of radiation exposure decreases significantly.

Standing at least 6 feet away helps minimize the exposure to scattered radiation, which can occur during X-ray procedures. This distance has been established by safety standards and guidelines to ensure that dental professionals maintain a safe working environment while effectively managing the risks associated with radiation.

In practice, dental professionals are often encouraged to use protective barriers and positioning to further reduce exposure risks, but maintaining this minimum distance is a foundational principle in radiation health and safety protocols.
