Answer 1

Scattered radiation in radiographic images can produce fog, increase contrast, and increase grid cutoff.

Step-by-step explanation:

The effects of scattered radiation on a radiographic image include:

1. It produces fog: Scattered radiation can contribute to a decrease in image quality by causing a haze or fog on the image, reducing sharpness and contrast.
2. It increases contrast: While scattered radiation can reduce contrast in an image, it can also increase it, depending on the technique used. Scatter can enhance the visibility of certain structures and improve image interpretation.
3. It increases grid cutoff: Scatter radiation can cause grid cutoff, which is a decrease in the intensity of the primary beam due to interactions with the grid. This can lead to underexposure and decreased image quality.
