Each of the following is an advantage of digital imaging except one. Which one is the exception?
A. It reduces radiation over film-based radiography.
B. It eliminates the need for the darkroom and processing chemistry.
C. It allows the use of pointed cones without radiation hazards.
D. It avoids the need for disposal of hazardous materials such as lead foils from film packets.
Answer:C
