Morphology

radiopacity = radiopaque (semi-transparent) = radi + opaque + ity

Formed by the adjective 'radiopaque' plus the nominalizing suffix '-ity'; the components are semantically clear but the combining form 'radi(o)-' and the medical technicality may be unfamiliar to learners.

Etymology

Radiopacity combines the part radio- meaning 'ray' and opacity meaning 'not letting light through'. So something with high radiopacity blocks X-ray 'rays' and shows up clearly on an X-ray image.
