Question

Using E-speed film (instead of D-speed film) reduces the radiation exposure to the patient by approximately:

A) 20%
B) 30%
C) 50%
D) 70%

Answer 1

Using E-speed film instead of D-speed film can reduce patient radiation exposure by about 50%, offering a significant improvement in patient safety during radiographic procedures.

Step-by-step explanation:

The question relates to the reduction of radiation exposure to a patient when using E-speed dental film compared to D-speed film. E-speed film is a faster film, which means it requires less radiation exposure to produce an image of similar density. Using E-speed film instead of D-speed film reduces the radiation exposure to the patient by approximately 50%.
