X-Ray Section: Utah X-Ray Data: Dental Bite-wing ESE Data

 

Dental graph.In the period 1994 to 1995 a survey of 419 intraoral 70 kVp x-ray units was completed in Utah by the Division of Radiation Control. The goal was to evaluate exposure to an average adult for a lateral posterior Bite-wing. Figure 1 is the summary of exposures obtained from this survey.

The information is expressed as the percentage of x-ray units which exhibited ESE within certain ranges. For example 8% of the units gave ESE values in the range of 300 to 349 mR. For the survey the average ESE was 247 mR. Of the x-ray units surveyed 15% gave ESE greater than 342 mR!!
