Scatter radiation on a radiographic image primarily results in

• A. Increases sharpness
• B. Produces fog
• C. Decreases density
• D. Improves image contrast

Answer: (B)

Scatter radiation adds unwanted photons to the image from many directions, causing a uniform hazy exposure across the receptor. This extra exposure fills in the gaps between areas of differing tissue attenuation, so the image loses contrast and appears foggy. The visible effect is a washed-out look that makes details harder to distinguish, rather than sharpening edges. It isn’t about increasing sharpness, nor about reliably decreasing density; the key impact is the fog that reduces image contrast. Techniques like using a grid or tighter collimation help cut down scatter and restore contrast.
