Morphology

radiotracer = tracer (semi-transparent) = radio + trace + er

Formally built from 'radio' + 'tracer' and indicates a tracer that involves radioactivity, but the meaning is technical and could be confused with 'radio' (broadcast) by learners.

Etymology

Radiotracer joins radio-, from a root meaning 'ray' as in radio, and trace, meaning 'to follow' or 'mark'. So a radiotracer is like a tiny 'ray' marker doctors can 'follow' inside the body to see how blood or other parts move.
