Root Explanation

Radiolabelled → It is formed from "radio-" (from Latin "radius", meaning ray) and "labelled" (from Old French "label", meaning a small note or tag). The term refers to something that has been tagged or marked with a radioactive label, indicating the presence of radiation.

Memory Tip

Think of 'ray' ('radio-') to remember that 'radiolabelled' means something marked with a radioactive tag.
