Which statement best describes differences between film-based and digital radiography in relation to radiation exposure?

• A. Digital radiography generally requires less exposure due to higher detector sensitivity and dynamic range; film-based generally requires higher exposure for adequate density; technique and processing also play a role.
• B. Digital radiography generally requires more exposure because of processing constraints and sensor limitations.
• C. Film-based radiography requires less exposure due to slower processing.
• D. Exposure levels are identical for both film-based and digital radiography.

Answer: (B)
