radiopacity

[-pas′itē]

Etymology: L, radiare, to emit rays, opacus, obscure

the ability to stop or reduce the passage of x-rays. Bones have relative radiopacity and therefore display as white areas on an exposed x-ray film. Lead has marked radiopacity and therefore is widely used to shield x-ray equipment and atomic power sources. Also called radiodensity. radiopaque, adj.

radiodensity.

radiopacity (rā´dēōpas´itē),

n relative term referring to the considerable attenuation of a radiographic beam produced by materials of relatively high atomic number. The image on a radiograph of such materials is relatively light because less radiation passes through, which prevents the exposure of the film in that area.
