Describing a material that allows x-rays or other types of radiation to pass through it easily.
The radiolucent material was used in the medical imaging process to ensure clear results.
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.
Think of 'rays' ('radio-') passing through something that 'shines' or is 'clear' ('lucent') — that's why radiolucent means allowing rays to pass through.
