1. Provide a description of double sided screen film cassettes, which feature intensifying screens.

2. What materials are likely used in these cassettes, assuming that they emit green visible light?

3. The X-Ray film used has a relative speed of 400, what does this describe?

4. Describe the composition and characteristics of double-emulsion X-Ray film.

5. Define the variables of the following equation,

OD = -log(T)OD = Optical Density T = Transmittance

where , T = I/10

and , I = IO e^(-μd)

6. Define contrast and latitude in reference to radiographic imaging.

7. Define noise and mottle within radiographic imaging and the effect of increasing beam energy on noise.

8. Describe the difference between low and high contrast X-ray films. What are these films typically used for?

9. Mention the technical specifications of the Nuclear Associates Densitometer used in measuring optical density.
