Radiation exposures around a panoramic dental x-ray unit.
To evaluate the radiation hazard in the vicinity of a panoramic x-ray unit, Ektaspeed periapical films were placed in an array behind and to the side of the unit. They were left in place for 7 months, during which 1414 examinations were carried out. The maximum exposure at 80 cm from the patient was determined to be about 1 mGy in 7 months with a heavy workload. This shows clearly that no special environmental shielding barriers are necessary around this unit.
