What is the recommended distance an operator should stand from the primary x-ray beam to minimize exposure?

Explanation:
Maximizing distance from the primary x-ray beam reduces radiation exposure because exposure falls off quickly with distance (the inverse square law). In dental radiography, the recommended safety practice is to stand at least six feet away from the source of the x-rays. If possible, pair that with being behind a protective barrier, which adds shielding. Distances closer than six feet place you in a higher scatter field, increasing dose, while standing farther away is effective but not necessary given the standard guideline. So, six feet away is the best protection within typical clinical setups.
