How does exposure affect the quality of a radiographic image?

The statement that proper exposure ensures clear images is accurate because exposure directly influences the contrast and visibility of the features within a radiographic image. When the exposure is appropriately calibrated for the material and thickness being radiographed, the resulting image can effectively highlight differences in density and structural details. Underexposure can lead to images that are too light, resulting in a loss of detail and making it difficult to discern features, while overexposure can cause the image to be too dark, obscuring crucial information. Therefore, achieving the correct exposure is critical for producing high-quality images that facilitate accurate interpretation and assessment in radiographic testing.
