Root Explanation

Radiocarbon is formed from "radio-" (from Latin 'radius', meaning ray) and "carbon" (from Latin 'carbo', meaning coal or carbon). The term refers to a type of carbon that is radioactive, emitting rays as it decays.

Memory Tip

Think of 'rays' ('radio-') being emitted by a special type of 'carbon' — that's why radiocarbon refers to carbon that gives off radiation.
