Questions and Answers

What is the purpose of chemical processing in radiographic film development?

  • To create the latent image
  • To make the latent image visible (correct)
  • To increase the film's contrast
  • To store the film for future use

What is the consequence of stacking boxes of film horizontally?

  • It may cause pressure artifacts on the film (correct)
  • It improves the organization of the film
  • It prevents moisture damage
  • It protects the film from light exposure

Which statement correctly describes the latent image?

  • It can be seen without chemical processing
  • It is the same as the manifest image
  • It is an invisible image formed by radiation exposure (correct)
  • It is produced by exposure to water
