How much less radiation exposure is a digital radiograph purported to be over a fast speed film–based radiograph?
a. 0 to 20 percent
b. 0 to 30 percent
c. 0 to 50 percent
d. 0 to 80 percent
c. With the use of fast-speed intraoral film and the fast-speed extraoral film and screen combinations the actual radiation reduction of digital imaging over film-based radiography may be 0 to 50 percent. Claims for up to 80 percent radiation reduction are most often accurate when the digital exposure is compared to slower D-speed film.
