What is the result of inadequate exposure on a radiograph?

Inadequate exposure on a radiograph primarily leads to increased noise in the image. When an image is underexposed, the amount of radiation reaching the film or digital detector is insufficient. This can lead to a grainy appearance or a lack of clarity, which is often termed 'noise.' The noise can obscure useful diagnostic information, making it difficult for radiologists and technicians to interpret the images accurately.

Increased noise can result from the insufficient quantity of photons that have interacted with the detector, making it difficult to distinguish between the various tissues or structures being imaged. Therefore, adequate exposure is crucial for producing high-quality radiographs where diagnostic features can be clearly seen.
