Concerns about Radiation

Possible health risks of exposure tolow-dose radiation in children, who appear to be more at risk than adults,include parotid, bone marrow, and thyroid cancer.20Even though there is no conclusive evidence that the small, infrequent doses ofradiation from dental radiographs increase risk of malignant disease,unnecessary radiation to the patient should be avoided, and care used to reduceradiation exposure if radiography is necessary.2,21This can include use of a thyroid shield, use of a rectangular collimation whichlimits the shape of the X-ray beam and reduces radiation exposure by 50%, or useof the fastest film type (the F-type) or digital radiography.2
