Although our office employs the latest technology to minimize the amount of radiation in each high quality x-ray, it remains that unwanted radiation gets scattered away from the intended target. Although this amount of radiation is significantly low, we believe it is always better act with utmost caution. With repeated exposure, even these low levels can build up, as it takes a while for the body to dissipate the absorbed radiation. For the patient who has been given a couple of x-rays over a few months, this is not of concern. However, for the dental staff, we leave the room while taking x-rays as we take many of these each day.
