FINAL REVIEW 2026 BUNDLED QUESTIONS
ANSWERS GUARANTEED PASS
◉ What kind of Dynamic Range does film have? Answer: A limited
Dynamic Range.
◉ What does a limited Dynamic Range make film sensitive to ?
Answer: Underexposure and Overexposure.
◉ What does having a Limited Dynamic Range restrict in film
radiography? Answer: The visibility of structures that differ greatly
in x-ray attenuation.
◉ What does radiographic film serve as a medium for? Answer:
Image acquisition, processing, and display.
◉ In general, what is film more sensitive to? Answer: Light
◉ What is film less sensitive to? Answer: X-Rays
◉ What kind of coating does film have? Answer: A single or double
emulsion coating.
,◉ What is the composition of radiographic film? Answer: -
Supercoat
- Emulsion
- Adhesive
- Film Base
◉ In the composition of radiographic film, what is the Supercoat
layer? Answer: A durable protective layer.
◉ In the composition of radiographic film, what is the Emulsion
layer? Answer: Radiation and Light sensitive layer.
◉ In the composition of radiographic film, what is the adhesive
layer? Answer: Adheres layers together.
◉ In the composition of radiographic film, what is the Film Base
layer? Answer: Polyester layer that gives the film physical durability.
◉ What does the emulsion contain? Answer: Crystals
◉ What do Crystals in the emulsion do? Answer: Absorb radiation.
, ◉ Where are electrons freed from? Answer: The ionized crystal
atoms.
◉ What happens with ionized crystal atoms? Answer: Electrons are
freed from them.
◉ Gurney Mott Theory Answer: - Sensitivity speck entraps free
electrons.
- Silver ions collect at speck and become latent image centers.
◉ In the Gurney Mott Theory, what happens to free electrons?
Answer: They are entrapped by sensitivity specks.
◉ Gurney Mott Theory, what is the purpose of a sensitivity speck?
Answer: Entraps free electrons.
◉ In the Gurney Mott Theory, what collects at speck? Answer: Silver
Ions
◉ In the Gurney Mott Theory, where do Silver Ions collect? Answer:
At the Sensitivity Specks.
◉ In the Gurney Mott Theory, once Silver Ions collect at speck, what
happens? Answer: The silver ions become latent image centers.
