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
Explanation: A) 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.
B) 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.
