• Developing

• Washing

• Fixing

• Drying

What is one purpose of the fixing stage in film processing?

• To soften the film emulsion

• To wash away excessive developer

• To convert the latent image to the visible image

• To clear away the unexposed/undeveloped silver halide crystal

What is the chemical compound that allows film to respond to light?

• phosphor crystals

• elemental silver

You have just puchased a new cassette with rare-earth screens. Which of the following is true?

• You should have a green light in the dark room

• You should use green-receiving (green sensitive) film

• You should use blue-receiving (blue sensitive) film

• You should have a green light in the dark room

An intensifying screen that contains large calcium tungstate crystals produces which of the following characteristics (compared to that with smaller crystals)?

• Fast screen, more detail, high grain

• Fast screen, less detail, high grain

• Slow screen, less detail, high grain

• Slow screen, more detail, low grain

In film radiography, calcium tungstate screens:

• Fluoresce in the blue spectrum

• Fluoresce in the green spectrum

• Are more efficient than rare earth screens

• Should be used with a green-receiving film.

Which of the following is TRUE about an x-ray film cassette?

• It can be made of any plastic as long as it is bendable

• It is designed to absorb scatter radiation

• It must be sturdy and have a strong, reliable closure

Non-screen film would most likely be used to take which type of radiograph?

• Skull

• Abdomen

• OFA Hip

• Dental

What is the primary purpose of using a safelight in the darkroom during film processing?

• To harden the film emulsion

• To provide visibility without exposing the film

• To enhance the contrast of the developed film

• To speed up the drying process of the film

What step of film processing is eliminated when using an automatic film processor?

• Rinsing (Stop bath)

• Developing

• Drying

• Fixing
