Intraoral X-ray units
The indicated standard values are a recommendation, the dentist determines the individual setting of
the exposure values
A setting of 60 kV is preferred provided it can be set on the X-ray unit
The standard exposure values for F-speed film (e g Kodak Insight) can be used
The following table shows the standard values for the exposure time and the dose area product of a
PSP for an adult patient
