[Effective dosage equivalents in evaluating radiation burden in patients in stomatologic roentgenology].
Risk coefficients are the main quantitative parameter when determining the extent of X-ray load in patients investigated with roentgenography. A concept of effective dose equivalent HE is used for this purpose. The present study is aimed on the determination of the HE for both orthopantomography and routine extra-oral roentgenogram of the mandibula. Measurements were performed on Alderson Rando phantom. The resulting effective dose equivalent for investigation with orthopantomograph represented 99.0 mu Sv and 80.9 mu Sv for the extra-oral projection, respectively. Based on the results obtained, the load with dental X-ray was shown to be disproportionately high.
