Detailed explanation-1: -Radiopaque volumes of material have white appearance on radiographs, compared with the relatively darker appearance of radiolucent volumes. For example, on typical radiographs, bones look white or light gray (radiopaque), whereas muscle and skin look black or dark gray, being mostly invisible (radiolucent).
Detailed explanation-2: -Definition: radiopaque. radiopaque (rA-dE-O-pAk) Impenetrable by x-rays or any other form of radiation.
Detailed explanation-3: -Upon detection a chemical reaction occurs. The more radiodense the material, the greater the attenuation of the X-ray beam. Bone attenuates more than soft tissue and appears radiodense (white) on a radiograph. Tissues that do not diminish X-rays are radiolucent or darker on a radiograph.
