Root Explanation

Radioautography → It is formed from "radio-" (from Latin *radius*, meaning ray) and "autographia" (from Greek *autographos*, meaning self-written). The word refers to a method of imaging that uses rays to create a self-written record of the internal structure of an object.

Memory Tip

Think of 'rays' ('radio-') being used to create a 'self-written' image ('autographia') of something, which helps you remember that radioautography is a technique for imaging.
