Morphology
radiopharmaceutical = pharmaceutical (semi-transparent) = radio + pharmaceutical + radio
The term is formed by adding the combining form 'radio-' (relating to radiation) to 'pharmaceutical', but the sense is technical and 'radio' can be ambiguous for learners (e.g., 'radio' = broadcast).
Etymology
Radiopharmaceutical combines radio- ('ray' or 'radiation') and pharmaceutical (related to pharmacy, meaning 'medicine' or 'drug'). So, a radiopharmaceutical is a medicine that contains radiation and is used to find or treat disease.
