Radiation Health & SafetyQuestion 8 of 100
An office still uses film-based intraoral radiography. Which film speed should be selected to keep patient exposure as low as possible?
a.A-speed
b.D-speed
c.F-speed
d.C-speed
Explanation
F-speed film is the fastest intraoral film in common use and requires the least exposure time, so it delivers the lowest patient dose while maintaining diagnostic quality. D-speed requires roughly twice the exposure of F-speed. A-speed and C-speed are older, slower emulsions that demand even more radiation and are not recommended.
