Root Explanation

Autoradiograph → It is formed from "auto-" (meaning self) and "radiograph" (from "radius" meaning ray and "graph" meaning to write or record). The word refers to a self-recording image produced by the radiation emitted from a radioactive substance.

Memory Tip

Think of 'self' ('auto-') creating a 'record' ('radiograph') of its own radiation — that's how autoradiograph captures an image.
