Final answer:
Optimum film viewing requirements for radiographs include dim lighting, brief viewing time, large viewing distance, and a neutral background.
Step-by-step explanation:
Optimum film viewing requirements for radiographs include:
- Dim lighting: This helps to enhance the visibility of the images on the radiograph.
- Brief viewing time: Prolonged viewing can lead to eye strain, so it's important to limit the time spent viewing radiographs.
- Large viewing distance: Viewing the radiograph from a distance allows for a better overall view and reduces the need for constantly refocusing the eyes.
- Neutral background: A neutral background helps to focus attention on the radiograph itself, making it easier to interpret.
