Root Explanation

Radiolucent → It is formed from "radio-" (from Latin "radius", meaning ray) and "lucent" (from Latin "lucere", meaning to shine or give light). The term describes materials that allow radiation to pass through, appearing transparent to rays of light or other forms of radiation.

Memory Tip

Think of 'rays' ('radio-') passing through something that 'shines' or is 'clear' ('lucent') — that's why radiolucent means allowing rays to pass through.
